**Lets Physics That** started in 2012 as the basis of my masters degree final thesis. It was designed to help increase intrinsic motivation in
students, which it did to a certain extent (Click to read my thesis!). Since 2012 it has expanded enormously, and was rebranded in 2015 as 'Lets Physics
That'. It is now used by students as a homework tool, a practise tool, and an opportunity to extend their learning. It even forms the basis
of one of the courses I teach in my general physics class.

Students earn physical badges when they get to different levels.

**Lets Physics That** is now used as the basis for all homework I set.

- Students all have a sign in to
**Lets Physics That**. For every module we do in class they have access to tasks to help enrich this learning. - Students get to choose which tasks to do, this is to help weaker students practise the things they need review on, and stronger students to push forward and really test their understanding.
- Further to this, students also choose when to do the tasks - I only ask that on average they do 2-3 tasks per week. This is to help reduce stress on busy weeks.

This extension will give you a whole range of different circuits (of varying difficulties!) to check your electricity knowledge on. Test yourself on Voltage calculations, Current calculations, Series and Parallel circuits, Power calculations and calculating the total resistance of a circuit.

This extension will test your knowledge on all things Circular Motion. Apply your knowledge of Newtons laws to objects moving in non straight lines, testing yourself on Frequency, Velocity, Centripetal Force. Radian usage, calculating Arc length and more!

Test your writing skills in this extension to see how well you can define key ideas. Learn the definitions in practice mode (or by having a go at the other achievements in the topic!) then try out the tasks to get the points!

Electron transitions within energy levels are the result of either absorbed or emitted light radiation. Practice calculating wavelengths, frequencies and energy changes in this extension.

This large extension allows you to practice your energy calculations for various objects moving down various slopes. It goes from simple gravitational potential energy calculations, to more complicated velocity calculations, and all the way up to velocity calculations taking work into account.

This extension allows you to practice your mechanics. Specifically the motion of a box on a flat surface. You can calculate simple things such as weight, or normal forces, or move onto more advanced subjects such as work done from friction or deciding which way to box might be moving using Newtons Second Law.

This extension allows you to practice your mechanics. Specifically the motion of a box on a slope. You can calculate simple things such as weight, or normal forces, or move onto more advanced subjects such as work done from friction.

This extension allows you to pracice your use of a Temperature-Time, or Temperature-Energy graphs. It will test you on how you calculate the specific heat capacity, latent heat of a substance, or even how to calculate the power of a heater, given a T-t OR t-E graph.

The different apps students can use to practise their calculations in Physics.

A major part of **Lets Physics That** is the extension apps. These are designed to test the students and help them build their numerical physics
capabilities.

Extension apps are fully customisable within a topic. You can make them really easy so you can learn the basics, or you can make them really hard to really ensure you know the material well. Students can either free practise or they can complete the tasks based upon extensions to earn points for their efforts.

The best part about extension apps is that generate new questions every single time. No question is ever the same as the last, meaning there is always continual practise for the students... the extensions even randomise the information students are given in some cases to make them think more deeply about how to solve problems.
