Students test the freezing /melting point of water. Students record the time and temperature every 2 minutes for 6 minutes using a thermometer and a timer. What is the best way to report the results of this experiment? 5.2(G)

• A table

• A pie graph

• A sketch

• A list

An investigation is set up to explore what causes a solid to change into a liquid. Each lab group uses four ice cubes in a sealable bag. Two groups tape the bags of ice cubes on a window where sunlight will shine through. The other two groups place the bags inside a desk. Students then record their observations every half hour to determine what causes the change in state of matter. What is the variable within the experiment? 5.2(A)

• Sealable bag

• Four ice cubes

• Sunlight

• Length of time observed

Water undergoes changes in state because temperature affects the speed of its particles. Which of the following statements best explains why water changes into a gas when heated? 5.3(A)

• The lower the temperature, the slower the speed of the particles

• Particles of liquids can move from place to place

• The higher the temperature, the faster the speed of the particles

• Water takes the shape of its container

Which of these is the best conductor of electricity? 5.5(A)

• Glass rod

• Plastic tubing

• Cotton string

• Copper penny

Which of these is not soluble in water?

• Oil

• Honey

• Salt

• Sugar

Objects that blow into a swimming pool or that are dropped into the pool by swimmers need to be removed. These objects include foam cups, keys, and coins. Which of the following explains a useful method for removing some of these objects? 5.5(A)

• The keys and coins are less dense than water, so they can be easily picked up off the bottom of the pool by divers.

• The foam cups are less dense than water, so they can be removed from the surfaces with a pool cleaning net.

• The foam cups have the same density as water, so they can crumbled up for removal by the pool filter.

• The keys and coins have the same density as water, so they can wash away when the pool is drained,

Which of the following choices has the moon phases in the correct order?

• Full moon, new moon, waxing gibbous, first quarter, waxing crescent, waning gibbous, waning cresent, last quarter

• waxing gibbous, new moon, first quarter, waxing crescent, full moon, waning crescent, third/last quarter, waning gibbous

• New Moon, Waxing Crescent, First Quarter, Waxing Gibbous, Full Moon, Waning Gibbous, Third/last quarter, Waning Crescent

• New Moon, Waning Crescent, First Quarter, Waning Gibbous, Full Moon, Waxing Gibbous, Third/Last Quarter, Waxing Crescent
