During this activity, you use a whole host of STEM skills including the physics involved in skydiving and the interaction between gravity and air resistance. Your skydiver will start to accelerate downwards until it reaches terminal speed, this is the speed at which the drag from the air resistance balances the force of gravity pulling the skydiver down. You are also able to test variables including:

• The surface area of the parachute
• Dropping the parachute from different heights
• Changing the lengths of the elastic bands
• Making the parachute different shapes

Challenge yourself to use a full range of STEM skills in creating your pom-pom run from the engineering of the build to the maths of finding the correct angles to make sure the pom-pom runs and the science of the gravity behind how the pom-poms move down your run. Gravity is force that causes everything to fall towards the Earth.

Why not compare pom-pom runs and have a race against your friends or try different materials to investigate how they move down your pom-pom run?

Use your engineering, maths and technology skills making a scale model theatre. In this activity you need to think about the correct measurements to make a suitable space to put on your show, the materials you are going to use and the engineering of creating your scale model theatre.

Aim to use different materials to make different sets for each show you put on in your theatre, why not ask family and friends how they would rate each show and set?

Put your geometry skills to the test with this exploding shapes activity studying sizes, shapes, dimensions and angles. These will create flat shapes that are called 2D shapes having two dimensions of length and width.

How not try creating a 3D exploding shape plus investigate if different angles in your shape make a difference.

Your catapult works when the potential energy stored in a stretched rubber band is converted to kinetic energy when it snaps back to its loose shape, moving the catapult arm and the projectile. The catapult involves science and engineering skills.

Consider how levers work, looking for more real world examples of when these are used and how they are linked to your catapult.
