Year 5 have been given the challenge of designing and making toy Moon Buggies for children aged 9-10. The product specification is as follows:
- It must move using an elastic band ‘pull back’ mechanism
- Have 4 wheel and 2 axels
- The dimensions must not exceed an A4 piece of paper
- Be strong and robust to withstand regular play (on the moon’s surface)
- Include a chair for an astronaut
- Resemble a moon buggy and include features that a real Nasa Moon Buggy would have
- Be appealing to children aged 9-10 years old
The ‘pull back’ mechanism will be powered by an elastic band. To understand the concept of potential energy and kinetic energy, pupils have been exploring the game ‘Rubber Chicken Darts’.
As the rubber chicken is pulled back, potential (or stored) energy is created. As the chicken is released, the potential energy turns into kinetic energy and chicken is propelled forwards. The children discovered that the further the chicken’s tail is pulled back, the more potential energy is created and the further and faster the chicken will travel. The children's scores were high and the competition was fierce but it was a lot of fun! The winners were Njasha and Ellis! Congratulations!!!
This week, Year 5 will be designing their Moon Buggies and considering the size and surface of their wheels. They will be learning about friction and the purpose of tyres.
