Properties of Matter.

🎯 Your mission

Run the experiment. Find out what really happens.

⚡ 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

A mixture contains two or more substances that are not chemically combined. You can often separate a mixture using physical methods like filtering, evaporating, or using a magnet.

Safety First

Keep strong magnets away from phones, bank cards and anyone with a pacemaker.
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

Separate a mixture of sand, salt, and iron filings using a magnet, water, and a filter. Record each step and what you separated.
