Welcome to the Haunted Matter Lab!

Discover how molecules make solids stay firm and liquids flow freely.

Welcome to the Haunted Matter Lab! Everything in the universe is made of tiny particles called molecules. Solids keep their shape. Liquids take the shape of their container.

Spooky Solids

Solids have a fixed shape and fixed volume! They do not change shape when moved into a new container or cauldron.

🔬 Molecule Secret:

Particles are packed tightly together in rows and can only vibrate in place!

Halloween Solids:

  • Chocolate Bars
  • Carved Pumpkins
  • Candy Corn
  • Skeleton Bones
🧪

Licorice Liquids

Liquids have no fixed shape! They slide around and take the shape of whatever bottle or cauldron holds them.

🔬 Molecule Secret:

Particles stay close, but can roll, slide, and flow past one another!

Halloween Liquids:

  • Witch's Brew
  • Pumpkin Latte
  • Melted Candle Wax
  • Slime Juice
