Three States of Matter.

🎯 Your mission

Set it up. Test it. Be amazed.

⚡ The twist

Mixing two safe things doesn't always make a safe thing.

🤯

Mind = Blown

🌈 Every color you see is your brain inventing a translation of light frequencies.

🔮

Make a hypothesis first

Predict: will the mixture get hotter, colder, or stay the same?

What You'll Learn

Matter exists in three common states: solid, liquid, and gas. Solids have a fixed shape and volume, liquids have a fixed volume but take the shape of their container, and gases fill any container.

Key Words

Tap a word to see its definition.

Materials Needed

  • vinegar
  • baking soda
  • paper towels

Safety First

  • Wear eye protection, keep the substance off skin, and wash your hands when you finish.
  • Mop up spills straight away so nobody slips, and keep liquids away from sockets.

Steps

Step 1Read

Look at the vocabulary words and write a definition for each in your own words.

Step 2Do

Test 5 household liquids (vinegar, milk, lemon juice, baking soda water, soap) with pH paper. Classify each as acid, base, or neutral.

Step 3Observe

Draw a detailed diagram of what you observe.

Step 4Record

Write a conclusion: what did your results show? Did they match your prediction?
