- Understanding of projectile motion
- Knowledge of force and energy transfer
- Understanding of potential and kinetic energy
- Knowledge of simple machines and how they can be used to create complex machines
- Understanding of structural engineering and how to create a stable structure
Encourage the child to continue exploring the concepts of force and energy transfer by experimenting with different types of projectiles and materials. They can also explore the use of different types of simple machines in their creations and learn about the history and development of weapons technology.
