Chemical Reactions.
🎯 Your mission
Run the sim. Spot the pattern.
⚡ The twist
Color changes mean atoms are rearranging — even if you can't see them.
Mind = Blown
🧪 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
Mixtures can be homogeneous (uniform, like salt water) or heterogeneous (non-uniform, like trail mix). Colloids like milk appear uniform but contain tiny suspended particles.
Key Words
- endothermic
- exothermic
- reactant
Steps
Read about Chemical Reactions and write down three key facts.
Test 5 household liquids (vinegar, milk, lemon juice, baking soda water, soap) with pH paper. Classify each as acid, base, or neutral.
Note any unexpected results and think about why they happened.
Share your findings with the class or a partner and discuss what you learned.
