Lab Brief #1

🎯 Your mission

Run the experiment. Find out what really happens.

Nature loves to surprise the careful watcher.

What you'll learn

Minerals are naturally occurring, inorganic solids with a crystalline structure and definite chemical composition. Minerals are identified by hardness, luster, color, streak, and cleavage.

Key words

mineral
A natural solid found in the ground that makes up rocks.

Make a hypothesis first

Before you start: write down what you think will happen, and why.

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