A teacher blew up a balloon. Students observed the balloon getting bigger. What happened?

• The particles that make up the air around the balloon pushed the balloon, making it smaller.

An ice sculpture of a dolphin was ordered for a birthday party, but was left outside in the sun by mistake. When the party started, all that was left was a large puddle on the floor! The ice dolphin disappeared because

• The ice is a solid, and the heat from the sun caused the particles to stop moving

• The dolphin was a liquid and the heat from the sun caused it to freeze.

• The ice is a solid, and the heat from the sun caused the particles move around and become a liquid.

• The dolphin is made from water vapor gas

Katie wanted to make a model of matter by drawing particles. Katie decided to make a model of a solid. How should she draw the particles?

• She should only draw a few randomly arranged and spread out.

• She should draw the particles close together in rows.

• She should draw the particles close together, but arrange them at random.

• You cannot create a model of particles

Katie then decided to create a model of the particles in air. How should Katie arrange her particles to represent the air in the room?

• She should draw the particles so they are really far apart from each other and randomly arranged.

• She should draw the particles close together in rows

• She should draw the particles quite close together, but randomly arranged

• She cannot draw models of particles
