In the teapot example, what represents the liquid?

• The teapot/kettle

• The water inside

• The steam coming out of the spout

When looking at the teapot, what represents the gas?

• The water inside

• The steam coming out of the pot

True or False: All matter is made up of teeny particles (atoms).

• True

• False

What atoms combine together to make water?

• • carbon dioxide and oxygen

• • hydrogen and oxygen

• • calcium and oxygen

In solids, the particles-

• • are spaced far apart and move around a lot

• • are pretty close together, and move around a little bit

• • are packed closely together and barely move, staying pretty much where they are

What will happen to the particles when the ice melts (think about changing state from solid to liquid)?

• • nothing will change

• They will start moving faster

• • the particles will get even closer together

What state of matter have the molecules changed into?

• Solid

• Liquid

• Gas
