Molecule Simulator Project
(Idea created by Nicholas Barreira - 5th Grade Smith's class 2008)

Objective:
Create a Scratch Project that simulates the motion of Molecules. 

Standards:
M5P4 Students will make connections among mathematical ideas and to other disciplines.
S5P2 Students will explain the difference between a physical change and a chemical change.
a. Investigate physical changes by separating mixtures and manipulating paper to demonstrate examples of physical change.
b. Recognize that the changes in state of water (water vapor/steam, liquid, ice) are due to temperature differences and are examples of physical changes.
c. Investigate the properties of a substance before, during, and after a chemical reaction to find evidence of change.

Requirements:
1. Has at least 10 molecule sprites
2. Each molecule moves and bounces off edge and each other
3. Each molecule moves faster and slower depending on the energy variable.

Extras:
1. Molecules "stick" closer together when energy is lower.
2. Molecules move farther apart when energy is higher.
3. Label sprites show the states of matter (solid, liquid, gas) at different energy levels.

Directions:

1. Draw one molecule with Scratch
2. Create Scripts to allow molecule to move about screen randomly and bounce off the edge


3. Create Variable to simulate energy (speed) and have the molecule move faster and slower depending on energy
4. Copy the molecule to create at least 10.
5. Use label sprites to show change between states in matter (solid, liquid, gas) depending on energy (temperature)
6. Save your file with name: "Lastname Molecules"
