What Is Temperature?

๐ŸงชLab Brief #17

Matter and Atoms.

๐ŸŽฏ Your mission

Predict it first. Then prove yourself right (or wrong).

โšก The twist

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

๐Ÿคฏ

Mind = Blown

๐Ÿงช If you could remove all the empty space from atoms, the entire human race would fit in a sugar cube.

๐Ÿ”ฎ

Make a hypothesis first

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

What You'll Learn

Temperature measures how fast particles are moving. At absolute zero, particles have the least possible energy. Heating matter increases particle motion and can cause state changes.

Key Words

  • acid
  • base

Materials Needed

  • measuring cups
  • paper towels
  • thermometer
  • strainer

Safety First

  • Wear safety goggles when mixing liquids.
  • Wash hands after handling materials.

Steps

Step 1 โ€” Read

Look at the vocabulary words and write a definition for each in your own words.

Step 2 โ€” Do

Test how temperature affects dissolving: dissolve sugar in cold, warm, and hot water. Count stirs needed for each and create a data table.

Step 3 โ€” Observe

Use your senses (except taste) to describe what you notice.

Step 4 โ€” Record

Write a summary of your findings in 3-5 sentences.
