Particles in Motion

🧪Lab Brief #2

Properties of Matter.

🎯 Your mission

Set it up. Test it. Be amazed.

⚡ The twist

If it bubbles, something invisible is escaping.

🤯

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

Guess: will the fizz be loud, soft, or none at all?

What You'll Learn

Matter is made of tiny particles that are always in motion. In solids, particles vibrate in place; in liquids, they slide past each other; in gases, they move freely.

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 1 — Read

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

Step 2 — Do

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

Step 3 — Observe

Compare the before and after states.

Step 4 — Record

Write your conclusion: did the results match your hypothesis? What would you change next time?
