Properties of Matter.
🎯 Your mission
Learn the rule. Then catch nature using it.
⚡ The twist
Color changes mean atoms are rearranging — even if you can't see them.
Mind = Blown
🌈 Every color you see is your brain inventing a translation of light frequencies.
Make a hypothesis first
Before you mix: what color do you think it'll turn?
What You'll Learn
Density is how much mass is packed into a given volume. Objects denser than water sink, while less dense objects float. Oil floats on water because it is less dense.
Key Words
Tap a word to see its definition.
Steps
Look at the vocabulary words and write a definition for each in your own words.
Create a density column: carefully layer honey, dish soap, water, vegetable oil, and rubbing alcohol in a tall glass. Drop small objects in to test where they float.
Look for patterns in your observations.
Make a graph or chart showing your results.
