You can contrast the properties of water. You can take ice cubes from a freezer and put them in a glass. You can put water from a faucet into a pot and boil it on the stove. Where will you find water as a liquid turning into a gas?

• in the glass

• in the freezer

• on the stove

• from the faucet

Javier makes three balls out of clay. He puts all the clay balls on a balance and measures the total mass as 56 g. He then molds the clay into one big ball and measures its mass, which is 56 g. Analyze Javier’s data to construct a reasonable explanation for his findings.

• He measured incorrectly and should measure again.

• The whole is equal to the sum of its parts.

• The clay gains mass when it is one large ball.

• Dividing the clay resulted in some of it being lost.

Compare mixtures that you can identify. What do all of the mixtures have in common?

• They are a combination of substances that give off a gas.

• They are any type of matter that can change its shape or color.

• They are any type of matter that evaporates when heat is added.

• They are a combination of two or more substances that keep their identities.

Water changes states when energy is added or taken away. Predict what will happen to liquid water when heat is added.

• It will melt into a gas.

• It will evaporate into water vapor.

• It will freeze and become ice.

• It will condense into water droplets.

Mixtures cannot be separated physically.

• True

• False

Some of the ice in a student’s tea melts. Explain why.

• Ice turns to liquid water as it absorbs heat from the liquid.

• The tea is warm.

• The ice is cold.

• It became a solution.
