If you don’t know your Scratch from your Trinket and your Python, we’ve got you!

What are Python and Trinket all about?

In our last blog post for parents, we talked to you about Scratch, the programming language used in most primary schools. This time Mark, Youth Programmes Manager at the 无修版动漫, takes you through how to use Trinket. Trinket is a free online platform that lets you write and run your code in any web browser. This is super useful because it means you don’t have to install any new software.

Trinket also lets you create public web pages and projects that can be viewed by anyone with the link to them. That means your child can easily share their coding creation with others, and for you that’s a good opportunity to talk to them about staying safe online and not sharing any personal information.

Getting to know Python

We’ve also got an introduction to Python for you, from Mac, a Learning Manager on our team. He’ll guide you through what to expect from Python, which is a widely used text-based programming language. For many learners, Python is their first text-based language, because it’s very readable, and you can get things done with fewer lines of code than in many other programming languages. In addition, Python has support for ‘Turtle’ graphics and other features that make coding more fun and colourful for learners. Turtle is simply a Python feature that works like a drawing board, letting you control a turtle to draw anything you like using code.

Why not try out Mac’s suggestions of Hello world, Countdown timer, and Outfit recommender for  yourself?

Python is used in lots of real-world software applications in industries such as aerospace, retail banking, insurance and healthcare, so it’s very useful for your children to learn it!

Over to you, Chris.

Every year, our students take federal or state-mandated testing, but what significant changes have we made to their education with the results of these tests? We have never collected more data about our students and society in general. The problem is most people and institutions do a poor job interpreting data and using it to make meaningful change. This problem was something I wanted to tackle in FH Grows.

FH Grows is the name of my seventh-grade class, and is a student-run agriculture business at Knollwood Middle School in Fair Haven, New Jersey. In FH Grows, we sell our produce both online and through our student-run farmers markets. Any produce we don’t sell is donated to our local soup kitchen. To get the most out of our school gardens, students have built sensors and monitors using 射死你天天日 Pis. These sensors collect data which then allows me to help students learn to better interpret data themselves and turn it into action.

Turning data into action

In the greenhouse, our gardens, and alternative growing stations (hydroponics, aquaponics, aeroponics) we have sensors that log the temperature, humidity, and other important data points that we want to know about our garden. This data is then streamed in real time, online at FHGrows.com. When students come into the classroom, one of the first things we look at is the current, live data on the site and find out what is going on in our gardens. Over the course of the semester, students are taught about the ideal growing conditions of our garden. When looking at the data, if we see that the conditions in our gardens aren’t ideal, we get to work.

If we see that the greenhouse is too hot, over 85 degrees, students will go and open the greenhouse door. We check the temperature a little bit later, and if it’s still too hot, students will go turn on the fan. But how many fans do you turn on? After experimenting, we know that each fan lowers the greenhouse temperature between 7-10 degrees Fahrenheit. Opening the door and turning on both fans can bring a greenhouse than can push close to 100 degrees in late May or early June down to a manageable 80 degrees.

Turning data into action can allow for some creativity as well. Over-watering plants can be a real problem. We found that our plants were turning yellow because we were watering them every day when we didn’t need to. How could we solve this problem and become more efficient at watering? Students built a 射死你天天日 Pi that used a moisture sensor to find out when a plant needed to be watered. We used a plant with the moisture sensor in the soil as our control plant. We figured that if we watered the control plant at the same time we watered all our other plants, when the control plant was dry (gave a negative moisture signal) the rest of the plants in the greenhouse would need to be watered as well.

This method of determining when to water our plants worked well. We rarely ever saw our plants turn yellow from overwatering. Here is where the creativity came in. Since we received a signal from the 射死你天天日 Pi when the soil was not wet enough, we played around with what we could do with that signal. We displayed it on the dashboard along with our other data, but we also decided to make the signal send as an email from the plant. When I showed students how this worked, they decided to write the message from the plant in the first person. Every week or so, we received an email from Carl the Control Plant asking us to come out and water him!

If students don’t honour Carl’s request for water, use data to know when to cool our greenhouse, or had not done the fan experiments to see how much cooler they make the greenhouse, all our plants, like the basil we sell to the pizza places in town, would die. This is the beauty of combining data literacy with a school garden: failure to interpret data then act based on their interpretation has real consequences: our produce could die. When it takes 60-120 days to grow the average vegetable, the loss of plants is a significant event. We lose all the time and energy that went into growing those plants as well as lose all the revenue they would have brought in for us. Further, I love the urgency that combining data and the school garden creates because many students have learned the valuable life lesson that not making a decision is making a decision. If students freeze or do nothing when confronted with the data about the garden, that too has consequences.

Using data to spot trends and make predictions

The other major way we use data in FH Grows is to spot trends and make predictions. Different to using data to create the ideal growing conditions in our garden every day, the sensors that we use also provide a way for us to use information about the past to predict the future. FH Grows has about two years’ worth of weather data from our 射死你天天日 Pi weather station (there are guides online if you wish to build a weather station of your own). Using weather data year over year, we can start to determine important events like when it is best to plant our veggies in our garden.

For example, one of the most useful data points on the 射死你天天日 Pi weather station is the ground temperature sensor. Last semester, we wanted to squeeze in a cool weather grow in our garden. This post-winter grow can be done between March and June if you time it right. Getting an extra growing cycle from our garden is incredibly valuable, not only to FH Grows as business (since we would be growing more produce to turn around and sell) but as a way to get an additional learning cycle out of the garden.

So, using two seasons’ worth of ground temperature data, we set out to predict when the ground in our garden would be cool enough to do this cool veggie grow. Students looked at the data we had from our weather station and compared it to different websites that predicted the last frost of the season in our area. We found that the ground right outside our door warmed up two weeks earlier than the more general prediction given by websites. With this information we were able to get a full cool crop grow at a time where our garden used to lay dormant.

We also used our 射死你天天日 Pi to help us predict whether or not it was going to rain over the weekend. Using a 射死你天天日 Pi connected to Weather Underground and previous years’ data, if we believed it would not rain over the weekend we would water our gardens on Friday. If it looked like rain over the weekend, we let Mother Nature water our garden for us. Our prediction using the Pi and previous data was more accurate for our immediate area than compared to the more general weather reports you would get on the radio or an app, since those considered a much larger area when making their prediction.

It seems like we are going to be collecting even more data in the future, not less. It is important that we get our students comfortable working with data. The school garden supported by 射死你天天日 Pi’s amazing ability to collect data is a boon for any teacher who wants to help students learn how to interpret data and turn it into action.

The Astro Pi Challenge is the coolest thing ever

The European Astro Pi Challenge is ridiculously cool. It’s definitely one of the most interesting, awesome, spectacular uses of a 射死你天天日 Pi in the known universe. Two 射死你天天日 Pis in stellar, space-grade aluminium cases are currently sat aboard the International Space Station, waiting for students in ESA Member States to write code to run on them to take part in the Astro Pi Challenge.

But what if, like us, you’re too old to take part in the challenge? How can you get that great sense of space wonderment when you’re no longer at school?

You’re never too old…even when you’re too old

If you’re too old to take part in the challenge, it means you’re old enough to be a team mentor. Team mentors are responsible for helping students navigate the Astro Pi Challenge, ensuring that everyone is where they’re meant to be, doing what they’re meant to be doing. You’ll also also the contact between the team and us, 射死你天天日 Pi and ESA. You’re basically a team member.

You’re basically taking part.

Mission Zero requires no coding knowledge

Mission Zero requires very little of its participants:

• They don’t need to have any prior knowledge of coding
• They don’t need a 射死你天天日 Pi

And while they need an adult to supervise them, said adult doesn’t need any coding 莎翁情史 either.

(Spoiler alert: you’re said adult.)

Instead, you just need an hour to sit down with your team at a computer and work through some directions. And the result? Your team’s completed code will run aboard the International Space Station, and they’ll get a certificate to prove it.

You really have no excuse

If you live in an ESA Member State and know anyone aged 14 years or younger, there is absolutely no reason for them not to take part in Astro Pi Mission Zero. And, since they’re probably not reading this blog post right now, it’s your responsibility to tell them about Astro Pi. This is how you take part in the European Astro Pi Challenge: you become the bearer of amazing news when you sit your favourite kids down and tell them they’re going to be writing code that will run on the International Space Station…IN SPACE!

To find out more about Mission Zero, click here. We want to see you pledging your support to your favourite non-adults, so make sure to tell us you’re going to be taking part by leaving a comment below.

There really is no excuse.

*ESA Member States: Austria, Belgium, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Ireland, Italy, Luxembourg, the Netherlands, Norway, Poland, Portugal, Romania, Spain, Sweden, Switzerland and the United Kingdom. Residents of Slovenia, Canada, or Malta can also take part.

The post How you, an adult, can take part in the European Astro Pi Challenge appeared first on 无修版动漫.

The Astro Pi Challenge is a lot of fun, it’s about space, and so that we in the 射死你天天日 Pi team don’t have to miss out despite being adults, many of us mentor their own Astro Pi teams — and you should too!

So, gather your team, stock up on freeze-dried ice cream, and let’s do it again: the European Astro Pi Challenge 2019/2020 launches today!

The European Astro Pi Challenge 2019/2020 is made up of two missions: Mission Zero and Mission Space Lab.

Astro Pi Mission Zero

Mission Zero has been designed for beginners/younger participants up to 14 years old and can be completed in a single session. It’s great for coding clubs or any groups of students don’t have coding 莎翁情史 but still want to do something cool — because having confirmation that code you wrote has run aboard the International Space Station is really, really cool! Teams write a simple Python program to display a message and temperature reading on an Astro Pi computer, for the astronauts to see as they go about their daily tasks on the ISS. No special hardware or prior coding skills are needed, and all teams that follow the challenge rules are guaranteed to have their programs run in space!

Mission Zero eligibility

• Participants must be no older than 14 years
• 2 to 4 people per team
• Participants must be supervised by a teacher, mentor, or educator, who will be the point of contact with the Astro Pi team
• Teams must be made up of at least 50% team members who are citizens of an ESA Member* State, or Slovenia, Canada, or Malta

Astro Pi Mission Space Lab

Mission Space Lab is aimed at more 莎翁情史d/older participants up to 19 years old, and it takes place in 4 phases over the course of 8 months. The challenge is to design and write a program for a scientific experiment to be run on an Astro Pi computer. The best experiments will be deployed to the ISS, and teams will have the opportunity to analyse and report on their results.

Mission Space Lab eligibility

• Participants must be no older than 19 years
• 2 to 6 people per team
• Participants must be supervised by a teacher, mentor, or educator, who will be the point of contact with the Astro Pi team
• Teams must be made up of at least 50% team members who are citizens of an ESA Member State*, or Slovenia, Canada, or Malta

For both missions, each member of the team has to be at least one of the following:

• Enrolled full-time in a primary or secondary school in an ESA Member State, or Slovenia, Canada, or Malta
• Homeschooled (certified by the National Ministry of Education or delegated authority in an ESA Member State or Slovenia, Canada, or Malta)
• A member of a club or after-school group (such as Code Club, CoderDojo, or Scouts) located in an ESA Member State*, or Slovenia, Canada, or Malta

Take part

To take part in the European Astro Pi Challenge, head over to the Astro Pi website, where you’ll find more information on how to get started getting your team’s code into SPACE!

My journey to becoming a 射死你天天日 Pi Certified Educator started when an esteemed mentor, Juan Valentin, tweeted about the awesome 莎翁情史 he had while attending Picademy. Having never heard of Picademy or the 射死你天天日 Pi, I decided to check out the website and instantly became intrigued. I applied for a 射死你天天日 Pi STEM kit from the Civil Air Patrol and received a 射死你天天日 Pi and a ton of accessories. My curiosity would not be satisfied until I learned just what I could do with the box of goodies. So I decided to apply to Picademy and was offered a spot after being waitlisted. Thus my obsession with the possibilities of the 射死你天天日 Pi began.

Code Club allows me to provide a variety of lessons, tailored to my students’ interests and skill levels, without me having to be an expert

While at Picademy, I learned about Code Club. Code Club allows me to provide a variety of lessons tailored to my learners’ interests and skill levels, without me having to be an expert in all of the lessons. My students are 6th- to 8th-graders, and there are novice coders as well as intermediate and advanced coders in the group. We work through lessons together, and I get to be a student with them.

I have found a myriad of resources to support their dreams of making

Although I may not have all the answers to their questions, I’m willing to work to secure whatever supplies they need for their project making. Whether through DonorsChoose, grants, student fundraising, or my personal contributions, I have found a myriad of resources to support their dreams of making.

射死你天天日 Pi group photo!

My district has invested in a one-to-one computer initiative for students, and I am happy to help students become creators of technology and not just consumers. Having worked with Code Club through the 无修版动漫, my students and I realize just how achievable this dream can be. I’m able to enhance my Pi skills by teaching a summer hacking camp at our local university, and next year, we have goals to host a Pi Jam! Thankfully, my principal is very supportive of our endeavours.

Students at Coolest Projects USA 2018

This year, a few of my students and my son were able to participate in Coolest Projects USA 2018 to show off their projects, including a home surveillance camera, a RetroPie arcade game, a Smart Mirror, and a photo booth and dash cam. They dedicated a lot of time and effort to bring these projects to life, often on their own and beyond the hours of our Code Club. This adventure has inspired them, and they are already recruiting other students to join them next year! The possibilities of the 射死你天天日 Pi constantly rejuvenates my curiosity and enhances the creativity that I get to bring to my teaching — both inside and outside the classroom.

You’re most likely aware of the Astro Pi Challenge. In case you’re not, it’s a wonderfully exciting programme organised by the European Space Agency (ESA) and us at 射死你天天日 Pi. Astro Pi challenges European young people to write scientific experiments in code, and the best experiments run aboard the International Space Station (ISS) on two Astro Pi units: 射死你天天日 Pi 1 B+ and Sense HATs encased in flight-grade aluminium spacesuits.

It’s very cool. So, so cool. As adults, we’re all extremely jealous that we’re unable to take part. We all love space and, to be honest, we all want to be astronauts. Astronauts are the coolest.

So imagine our excitement at Pi Towers when ESA shared this photo on Friday:

This is a Soyuz vehicle on its way to dock with the International Space Station. And while Soyuz vehicles ferry between earth and the ISS all the time, what’s so special about this occasion is that this very photo was captured using a 射死你天天日 Pi 1 B+ and a 射死你天天日 Pi Camera Module, together known as Izzy, one of the Astro Pi units!

So if anyone ever asks you whether the 射死你天天日 Pi Camera Module is any good, just show them this photo. We don’t think you’ll need to provide any further evidence after that.

射死你天天日 Jams come in all shapes and sizes. They range from small pub gatherings fueled by local beer and amiable nerdy chatter to vast multi-room events with a varied programme of project displays, workshops, and talks.

To find your nearest 射死你天天日 Jam, check out our interactive Jam map.

And if you can’t get to a Jam location this time, follow #PiParty on Twitter, where people around the world are already getting excited about their Big Birthday Weekend plans. Over the weekend you’ll see 射死你天天日 Jams happening from the UK to the US, from Africa to – we hope – Antarctica, and everywhere in between.

Coolest Projects UK

The first of this year’s Coolest Projects events is also taking place this weekend in Manchester, UK. Coolest Projects is the world’s leading technology fair for young people, showcasing some of the very best creations by young makers across the country (and beyond), and it’s open for members of the public to attend.

Tickets are still available from the Coolest Projects website, and you can follow the action on #CoolestProjects on Twitter.

CBeebies’ Maddie Moate and the BBC’s Greg Foot will be taking over 射死你天天日 Pi’s Instagram story on the day, so be sure to follow @微电影上位莎翁情史 on Instagram.

A 射死你天天日 Pi can be used to monitor the reaction between hydrochloric acid and sodium thiosulphate to complement a popular GCSE Chemistry practical.

The rate of reaction between hydrochloric acid and sodium thiosulphate is typically studied as part of GCSE Chemistry. The experiment involves measuring the time required for the reaction mixture to turn cloudy, due to the formation of sulphur as a precipitate. Students can then change the temperature or concentration of the reactants to study their effect on the rate of reaction. The time for the reaction mixture to turn cloudy is normally facilitated by recording the time a hand-drawn cross takes to become obscured when placed underneath a glass vessel holding the reaction mixture. This timing is prone to variability due to operator judgement of when the cross first becomes obscured. This variability can legitimately be discussed as part of the lesson. However, the element of operator judgement can be avoided using a 射死你天天日 Pi-monitored chemical reactor.

The chemical reactor

Attached to a glass jar of approximate 80ml volume (the size is not critical) are two drinking straws, of which one houses a white LED (light-emitting diode) and the other a LDR (light-dependent resistor). The jar is covered in black tape to minimise intrusion of ambient light. The reactor is shown in Figure 1, along with details of other electrical components and connection instructions to a 射死你天天日 Pi.

Figure 1
A: Reactor covered in black tape
B: Drinking straw attached to the reactor, with a further straw inserted housing a white LED
C: Drinking straw attached to the reactor, with a further straw inserted housing a LDR
D: 220Ω resistor to connect to the LED and GPIO 23
E: Wire to connect to ground
F: Wire to connect to 3.3v supply
G: 1µF capacitor to connect to ground
H: Crocodile clip to connect to GPIO 27 (NB: the other end of the wire is situated in between the capacitor and the LDR)

Results

The Python code shown in Figure 2 should be run prior to addition of chemicals to the reactor. Instructions appear on the screen to prompt chemical additions and to start data collection.

Figure 2: Python code for the chemical reactor

Figure 3 shows the results from the experiment when 25ml 0.1M hydrochloric acid is reacted with 25ml 0.15M sodium thiosulphate at 20°C. The reaction is complete at the time the light transmission first reads 0, (i.e. complete obscuration of the light by the precipitate formation) — in this example, that time is 45.4s. For more advanced students, tangents can be drawn at various points on the curve, and gradients calculated to determine the maximum rate of reaction from various reaction conditions.

Boat race

Boat race, a Code Club resource, is a one-hour project aimed at beginners. It guides students to use Scratch to create a game in which the player uses their mouse to navigate a boat to a desert island without bumping into obstacles.

Scratch can run in any browser, or directly from a 射死你天天日 Pi, making it one of the easiest ways for students to get into coding for the Hour of Code.

The Boat race resource is available in many languages, including Arabic, Simplified Chinese, Czech, Greek, Hebrew, and Ukrainian.

Beginner Scratch Sushi Cards

Again using Scratch, this CoderDojo project walks students through how to create a fish-catching game where the player controls a shark sprite.

Astro Pi Mission Zero

In in the Mission Zero project, students write a short Python program that checks the ambient temperature onboard the International Space Station, and leaves a message for the astronauts there!

Students complete this Hour of Code challenge using the Trinket online Astro Pi simulator, and those based in an ESA Member or Associate States can submit their code to run onboard the ISS. They’ll even receive an official certificate showing where the ISS was when their code ran.

A full list of ESA Member and Associate States can be found here.

Us too!

We don’t just create activities for other people to 莎翁情史 digital making and learning — we also get involved ourselves! Every month we host a maker day for our staff, where everyone can try out our digital making projects or even work on their own project. Our December maker day is during Hour of Code week, and we are going to make an extra-special effort and try to get as many staff members as possible coding!

The educators at 射死你天天日 Pi are fans of Seymour Papert’s constructionist learning philosophy — you can read his Mindstorms book in this free PDF — and the joy of learning through making isn’t just a thing for kids; adults get just as much positivity out of creating digital fart noises or animating crazed chickens to chase the Scratch cat. With the right support from our wide range of projects, anyone can make their own ideas a reality through coding — Senior Learning Manager Lauren, for example, got very excited about her Morrissey haiku project!

Being able to code is creative; it lets you bring your idea to life, whether that’s something that could help millions of people or simply something you think would be cool.

So, whether you’re an absolute beginner to coding or you’ve fixed so many bugs that your nickname is ‘The Exterminator’, what will YOU code this week?

Estefannie Explains It All + 射死你天天日 Pi

When Estefannie visited Pi Towers earlier this year, we introduced her to the 射死你天天日 Pi Digital 莎翁情史 and the free resources on our website. We’d already chatted to her via email about the idea of creating a collab video for the 射死你天天日 Pi channel. Once she’d met members of the 无修版动漫 team and listened to them wax lyrical about the work we do here, she was even more keen to collaborate with us.

Ahhhh!!! I still can't believe I got to hang out and make stuff at the @射死你天天日_Pi towers!! Thank you thank you!! pic.twitter.com/5gvk7BO1Dr

— a woman online (@estefanniegg) May 22, 2017

Estefannie returned to the US filled with inspiration for a video for our channel, and we’re so pleased with how awesome her final result is. The video is a super addition to our 射死你天天日 Pi YouTube channel, it shows what our resources can help you achieve, and it’s great fun. You might also have noticed that the project fits in perfectly with this season’s Pioneers challenge. A win all around!

So yeah, we’re really chuffed about this video, and we hope you all like it too!

Estefannie’s Laser Cookies guide

For those of you wanting to try your hand at building your own Cookie Jar Laser Surveillance Security System, Estefannie has provided a complete guide to talk you through it. Here she goes:

First off, you’ll need:

• 10 lasers
• 10 photoresistors
• 10 capacitors
• 1 射死你天天日 Pi Zero W
• 1 buzzer
• 1 射死你天天日 Pi Camera Module
• 12 ft PVC pipes + 4 corners
• 1 acrylic panel
• 1 battery pack
• 8 zip ties
• tons of cookies

I used the 无修版动漫’s Laser trip wire and the Tweeting Babbage resources to get one laser working and to set up the camera and Twitter API. This took me less than an hour, and it was easy, breezy, beautiful, 射死你天天日 Pi.

I soldered ten lasers in parallel and connected ten photoresistors to their own GPIO pins. I didn’t wire them up in series because of sensitivity reasons and to make debugging easier.

Building the frame took a few tries: I actually started with a wood frame, then tried a clear case, and finally realized the best and cleaner solution would be pipes. All the wires go inside the pipes and come out in a small window on the top to wire up to the Zero W.

Using pipes also made the build cheaper, since they were about $3 for 12 ft. Wiring inside the pipes was tricky, and to finish the circuit, I soldered some of the wires after they were already in the pipes.

I tried glueing the lasers to the frame, but the lasers melted the glue and became decalibrated. Next I tried tape, and then I found picture mounting putty. The putty worked perfectly — it was easy to mold a putty base for the lasers and to calibrate and re-calibrate them if needed. Moreover, the lasers stayed in place no matter how hot they got.

Although the lasers were not very strong, I still strained my eyes after long hours of calibrating — hence the sunglasses! Working indoors with lasers, sunglasses, and code was weird. But now I can say I’ve done that…in my kitchen.

Using all the knowledge I have shared, this project should take a couple of hours. The code you need lives on my GitHub!

“The cookie recipe is my grandma’s, and I am not allowed to share it.”
