Energy is a very important thing in our lives. It gives us light, lets us move, and allows us to use electrical devices, like a microwave to heat up food.

We can have the kids roll a ball down a ramp, which will trigger dominos, which will be lightly tapped for easier assembly, to fall and the last one will fall on a ball and the ball will land on a light switch turning on a light. Attached to the switch will be dental floss. The floss will become tight and pull a lever. The lever, that was holding back a small cup with a sticker in it will fly to the kid. =Materials:= - Ball - Small Basket - Stickers - A Light Bulb - A Switch for the Light - A Block of Wood - A Ramp for the ball to go down - Yarn - Tape

When the metal ball rolls down the hill, it starts to get more kinetic energy and as it's going back up the hill, it's potential energy grows. When you used two metal balls, the friction between them causes them to slow down so it won't roll for very long. We can use this in our project for when we roll a ball down a ramp to hit something and causing something to trigger a switch.

Energy is never lost it's transformed into different types of energy. An example is in the cartoon we had for homework whe the boot fell (gravitational energy) onto the switch that turned on the iron (thermal/electrical energy).

Types of Energy: Mechanical: Energy created by physial movement or rotation. Chemical: Energy stored in a substance that can be released when the substance reacts. Electrical: is a potential energy associated with the conservative Coulomb forces within a defined system of point charges

The materials you originally see are what we thought we were going to use. The materials we ended up using were as follow: -Yarn - Ramp - Tape - Paper Clip - Lego Car w/ Cup On Top For Stickers - HotWheels Car - Pen for More Weight on Paperclip
