HS-PS1.7 Mathematical representation of Conservation of Matter

# data[].attributes.body
Create Turtles, move turtles, assign variables to turtles (mass).

# data[].attributes.body
We want students to see the mass of the reactants and the mass of the products change over time.  They should also see that the total mass of the system is remaining constant.

These values should be being calculated and plotted constantly.

# data[].attributes.body
Since we need molecules to decompose and synthesis (or whatever type of reaction) we think the most reasonable solution is for students to have the reactants die and then the products to hatch at the same location.

# data[].attributes.body
For students to implement the kinetic molecular model they need to be able to have turtles sense other turtles so they can determine if a collision has occurred.

Conservation of mass
will show reaction of different atoms and track mass of reactants and products
