Matter and Atoms.
🎯 Your mission
Predict it first. Then prove yourself right (or wrong).
⚡ 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?

Steps
Read about Matter and Atoms and write down three key facts.
Mix baking soda and vinegar in a sealed bag. Weigh the bag before and after. Did the mass change? Explain why or why not using the law of conservation of mass.
Compare the before and after states.
Write your conclusion: did the results match your hypothesis? What would you change next time?
