Elements and Compounds

Lab Brief #6

🎯 Your mission

Master the concept. Use it tomorrow.

⚡ The twist

Color changes mean atoms are rearranging — even if you can't see them.

What you'll learn

Elements are pure substances made of only one type of atom. Compounds are substances made of two or more elements chemically bonded in fixed ratios.

Key words

compound
A substance made when two or more elements join together chemically.
element
A pure material made of only one kind of atom.

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.

Step 1 of 4 · Read

Step 3 of 4 · Observe

Note any unexpected results and think about why they happened.

Step 4 of 4 · Record

Share your findings with the class or a partner and discuss what you learned.
