Sunshine City wants to lower heat by paving the sidewalks. Which

pavement is most likely a good choice?

• black pavement because it absorbs heat

• black pavement because it reflects heat

• white pavement because it reflects heat

• white pavement because it absorbs heat

Alex and Jade are conducting an experiment to measure how the sun

affects the evaporation of water. Alex places 50mL of water in the shade.

Jade places 50mL of water in direct sunlight. What will the students

most likely observe?

• The water in the sun will be warmer, causing the water to evaporate

  more quickly.

• The water in the shade will be cooler, causing the water to evaporate

  more quickly.

• The water in the shade will be warmer, causing the water to

  evaporate more slowly.

• The water in the sun will be cooler, causing the water to evaporate

  more slowly.

Which best explains why there are gaps between the concrete

sidewalks?

• When temperatures get cold, the gaps allow the concrete to expand

  without cracking.

• When temperatures get hot, the gaps allow the concrete to expand

  without cracking.

• When temperatures get cold, the gaps allow the concrete to contract

  without cracking.

• When temperatures get hot, the gaps allow the concrete to contract

  without cracking.

During winter months, people worry about the water pipes in their house

breaking. Which best explains why?

• Water in pipes can freeze, expand, and the added pressure can break

  water pipes.

• Water in pipes can melt, expand, and the added pressure can break

  water pipes.

• Water in pipes can freeze, contract, and the added pressure can

  break water pipes.

• Water in pipes can melt, contract, and the added pressure can break

  water pipes.

Why will it not be a good idea to carry extremely hot liquids in a thin

metal container?

• Heat travels through metal easily.

• The metal container will remain cool.

• Cold air travels through the metal too easily.

Lisa wants to make some dinners that she can freeze and pull out

quickly to put in the oven. What material should she use to store her

meals in the freezer and be able to put them directly in the oven?

• aluminum

• styrofoam

• plastic

A student notices that an inflated balloon gets larger when it is warmed by a lamp. Which best describes the mass of the balloon as a result of this change? 

• The mass of the balloon increases because the size of the balloon has increased. 
• The mass of the balloon increases because the temperature of the balloon has increased. 
• The mass of the balloon stays the same because the gas inside the balloon still has the same mass after it warms up. 
• The mass of the balloon stays the same because warming decreases the mass enough to cancel out the effect of increasing the size.

Which mixture could you separate by adding water and then pouring through a coffee filter?

• sand and salt, because the salt would dissolve and the sand would not
• baking soda and salt, because they both dissolve
• sugar and salt, because they both dissolve
• iron fillings and sand, because neither one dissolves
