Matter and Atoms.

๐ŸŽฏ Your mission

Play with the model. Break it. Understand it.

โšก The twist

If it bubbles, something invisible is escaping.

๐Ÿคฏ

Mind = Blown

๐Ÿ’ง Hot water can freeze faster than cold water under the right conditions. Nobody fully understands why.

๐Ÿ”ฎ

Make a hypothesis first

Guess: will the fizz be loud, soft, or none at all?

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
  • endothermic

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.
