Matter and Atoms.
๐ฏ Your mission
Run the sim. Spot the pattern.
โก The twist
Color changes mean atoms are rearranging โ even if you can't see them.
Mind = Blown
๐งช If you could remove all the empty space from atoms, the entire human race would fit in a sugar cube.
Make a hypothesis first
Before you mix: what color do you think it'll turn?
What You'll Learn
Chemical formulas show the types and numbers of atoms in a molecule. COโ has one carbon and two oxygen atoms. The subscript tells how many of each atom.
Key Words
- exothermic
- reactant
Steps
Read the introduction and identify the main idea of this lesson.
Build a model of an atom using craft supplies. Show protons, neutrons, and electrons in the correct arrangement. Label each particle.
Watch carefully for any changes and note the time.
Create a data table to organize your measurements.
