Freezing and Melting (Part 3).

๐ŸŽฏ Your mission

Play with the model. Break it. Understand it.

โšก The twist

Color changes mean atoms are rearranging โ€” even if you can't see them.

๐Ÿคฏ

Mind = Blown

๐ŸŒˆ Every color you see is your brain inventing a translation of light frequencies.

๐Ÿ”ฎ

Make a hypothesis first

Before you mix: what color do you think it'll turn?

What You'll Learn

Some changes can be reversed (melting ice) and some cannot (baking a cake).

Key Words

  • cool
  • mixture

Steps

Step 1 โ€” Read

Look at the new words. Can you say each one?

Step 2 โ€” Do

Put an ice cube on a plate and watch it for 10 minutes. Draw what it looks like every 2 minutes.

Step 3 โ€” Observe

Use your senses to describe what you notice.

Step 4 โ€” Record

Write 1-2 sentences about what happened.
