Properties of Matter.

🎯 Your mission

Predict it first. Then prove yourself right (or wrong).

⚡ The twist

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

🤯

Mind = Blown

💧 Hot water can freeze faster than cold water under the right conditions. Nobody fully understands why.

🔮

Make a hypothesis first

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

What You'll Learn

Solutions are special mixtures where one substance dissolves completely in another. Salt water is a solution where salt (solute) dissolves in water (solvent).

Key Words

Tap a word to see its definition.

Materials Needed

sugar

Safety First

Adult supervision required for any heating. Hot glassware looks identical to cold — use tongs.
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 how temperature affects dissolving: dissolve sugar in cold, warm, and hot water. Count stirs needed for each and create a data table.

Step 3 — Observe

Use your senses (except taste) to describe what you notice.

Step 4 — Record

Write a summary of your findings in 3-5 sentences.
