Transparent or Opaque?

Lab Brief #6

🎯 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.

What you'll learn

Light passes through transparent materials (glass), but not through opaque materials (wood).

Key words

material
The stuff something is made of, like wood, metal, or plastic.

Make a hypothesis first

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

Say your guess out loud — then find out if you were right.

Get ready

🧰 What you need

paper towels

⚠️ Safety first

Have an adult check your set-up before you start, and tidy everything away afterwards.

Step 1 of 4 · Read

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

Step 2 of 4 · Do

Stretch, bend, and tear different materials (paper, foil, rubber band). Record what happens to each.

Step 3 of 4 · Observe

Compare what happened to what you predicted.

Step 4 of 4 · Record

Tell the class one thing you learned today.

Question 1 of 2

Which material is transparent?

How sure are you?😐 maybe

Question 2 of 2

An opaque material is one that light:

How sure are you?😐 maybe

Mind = blown

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

Nice work!

You got 0 of 2 right.
