With this Physics and Computing activity, learn about the effects of gravity and how to simulate them in Scratch with code. You can learn more about the forces of gravity and the effects of weightlessness as well as more about British ESA Astronaut Tim Peake's mission aboard the International Space Station and the Astro Pi Project here: https://www.raspberrypi.org/competitions/astro-pi/

By creating a gravity simulator in Scratch, you will learn:
- About the force of gravity and how it is calculated on different planets in our solar system.
- How to import images into Scratch and use them as backgrounds and sprites.
- How to store data in variables.
- How to set and use an if condition.
- How to use multiply operators.

Suitable for KS2 and KS3 students.

I section 4 'The simulation Loop' I suggest you need to change the equation a little to match your (correct) script<br /> Velocity = Velocity + (0.1 x -9.81)<br /> Otherwise students may gain the impression that velocity is not changing. Which would really surprise them the first time they get to fly a real spaceship.

Great resource but the sentence, &quot;This is because everything becomes ​weightless ​outside of our planet, Earth.&quot; is wrong on many levels. I know we have to simplify and abstract in resources (ignoring microgravity here for example) but this is just plain wrong and will lead to misunderstanding. (The wording could take a cue from the the KS3 Science Programme of Study that says students should be taught that gravity is &quot;different on other planets and stars&quot; and about &quot;gravity forces acting at a distance on Earth and in space&quot;.)

Great tutorial well explained using real life situations (and cute little cats) to help understand using variables to store data and loops in Scratch. So glad to see that Scratch is still supported. This exercise would be ideal to modify using the Pico-Board as an extention you could shout at the microphone or hover your hand over the light sensor to give even more tactile effects.
