Day 1 Agenda

Energy is neither created nor destroyed: it is only transformed. There are many different forms of energy, including kinetic energy (the energy of motion), potential energy (energy that is considered stored because of an object’s position), mechanical energy (energy that performs work), and thermal (heat) energy. Kinetic and potential energy are often paired together in simple demonstrations, like dropping a book, jumping on a trampoline, or building cool machines like rubber band cars.

Elastic potential energy is stored in the rubber band when you twist it up. When the rubber band is released, the potential energy built up in twisting gets unloaded and turned into mechanical energy. The wheels push against the ground as the rubber band unwinds so that the only place the mechanical energy has left to go is into the weels in the form of torque, or force around an axis. This enables your car to roll forward.

We will be racing your cars tomorrow so your build needs to function. Your group will be given the same set of materials but can use your own if you wish. Use the internet for ideas as to what you can build with what you have or brought with you. Feel free to decorate your car.

Materials:

Wheels X4

Metal Axel X2

Wooden Popsicles (Multiple)

School Glue

Two Straws

One Pair of Scissors.

Card Board

Masking Tape

Rubber Band

Day 4 and 5 Ajenda

Electric Circuit Motor Car

Electrical circuits are essential to our modern civilization. They control lights across continents, keep planes flying through the air, and manage global communication. They also do more mundane things like the flow of electricity in flashlights or doorbells. Regardless of their function, all electrical circuits have certain things in common.

You will be provided with the basics to not only create an electrical circuit but one that will power your car. We will be racing your cars tomorrow so your build needs to function. Your group will be given the same set of materials but can use your own if you wish. Use the internet for ideas as to what you can build with what you have or brought with you. Feel free to decorate your car.

You will need to cut the top of the bottle to create a propeller. The propeller will be spun by the motor to create forward momentum. Be respectful of other people as this can be dangerous to others.
