Design and make a slingshot car
Design
• Designing a shape that reduces air resistance.
• Drawing a net to create a structure from.
• Choosing shapes that increase or decrease speed as a result of air resistance.
• Personalising a design.
Make
• Measuring, marking, cutting and assembling with increasing accuracy.
• Making a model based on a chosen design.
Evaluate
• Evaluating the speed of a final product based on: the effect of shape on speed and the accuracy of workmanship on performance.
Technical Knowledge
• To understand that all moving things have kinetic energy.
• To understand that kinetic energy is the energy that something (object/person) has by being in motion.
• To know that air resistance is the level of drag on an object as it is forced through the air.
• To understand that the shape of a moving object will affect how it moves due to air resistance.
