=1.) Potential and Kinetic Energy Lab= 1. What measurements do you need to find the Gravitational Potential Energy (GPE) of the car at the top of the ramp?
 * You'll need to know the car's weight and height to find the GPE

2. Calculations

3. What do you need to find the Kinetic energy of the car at the bottom of the hill?

4.Compare the potential energy at the top of the ramp with the kinetic energy of the car at the bottom of the ramp.
 * The difference between the PE (Potential Energy) and KE (kinetic energy) was that the PE changed to sound energy and thermal energy. This means that not all the PE changed to KE.

The Problem:
Burning fuels produces greenhouse gases that contribute to global warming which causes the melting of polar ice, alters the natural habitats of animals and contributes to extreme weather conditions

The Solution:
To solve the problem about the ice melting, altering the natural habitiats of animals, and contributing to extreme weather conditions, we can... If you create a blog or website, you can have individual sections for fundraisers, information, videos, petitions, and how to help. A website or blog can be seen all over the world, as long as there is internet. This means that anyone and EVERYONE can see it!
 * 1) Create a blog or website

Information:
Question: What is under our board? Hypothesis: We think that the shape will be a polygon. Ind. Variable: where the marble enters Dep. Variable: where the marble exits Costant: amount of times we rolled the marble, size of the marble

Inference:
We think our shape will be a circle or pentagon because of the way the marble entered and exited the board.
