Countdown to FSA Science Review #5

(Nature of Science)

Jim did an experiment about heating water. He discovered that when he put a wool cover on a glass full of water, the water got hotter than when it was covered with a cotton cover. He wonders whether his data are accurate. How should Jim determine whether his data is accurate?

• He should draw a conclusion.

• He should repeat the experiment.

• He should start collecting data.

• He should form a new question.

(Earth in Space and Time)

The planets in our Solar System are different in many ways. Their atmospheres are made up of different gases, they are different sizes, and they are different distances from the Sun. Which of the following is a characteristic that all the planets have in common?

• They all support human life.

• They all have rings.

• They all have moons.

• They all orbit the Sun.

(Earth Structures)

It is important to develop renewable energy sources like solar, wind, and hydroelectric power. What is the advantage of using these resources, instead of using fossil fuels?

• They make more energy than fossil fuels.

• They are cheaper to maintain than fossil fuels.

• They cannot be depleted or used up, like fossil fuels.

• They cannot be depleted or used up, like fossil fuels.

(Earth Systems and Patterns)

Bailey takes a can of soda out of the cold refrigerator. The doorbell rings, so she places the can on a table and goes to answer the door. When she returns to the kitchen, the outside of the can is completely wet and is sitting in a puddle of liquid. How could this have happened when she hadn't even opened the can?

• The can had a tiny leak that Bailey had not noticed.

• The can had frozen ice on the outside that melted at room temperature.

• The temperature in the room caused the liquid in the can to evaporate.

• Water vapor from the air condensed on the outside of the can.

(Properties of Matter)

The students in Ms. Smith's class are going to observe and describe the physical properties of a stone that has an irregular shape. What is the best way to calculate the stone's volume?

• Using a straight ruler, measure the length, width, and height of the stone in centimeters.

• Using a graduated cylinder partially filled with water, measure the amount of water displaced by the stone.

• Using a balance, measure the mass of stone.

• Using a tape measure and yarn, measure the stone's circumference and change it into inches.

(Changes in Matter)

Haley's mom filled an ice cube tray with water and placed it in the freezer to make ice for the school picnic. The tray contained 500 grams of water when she filled it. How will freezing the water affect its mass?

• Freezing the water will decrease its mass.

• Freezing the water will increase its mass.

• Freezing the water will not change its mass.

• Freezing the water will first increase and then decrease its mass.

(Forms of Energy)

For thousands of years, people have used the power of water to do work. One example is a hydroelectric dam. Hydroelectric dams, like the one shown on the left, use water to generate electricity. Which of the following best explains why people can use water to generate energy?

• Water flowing downhill has energy.

• Water contains a lot of heat energy.

• Water is a good conductor of electricity.

• Water easily absorbs energy from the Sun.

• magnetism

• shape

• temperature

• mass

(Organization of Living Organisms)

Blood is moved through the body by veins and arteries to all the different parts of the body. Which organ is responsible for pumping blood through the body?

• kidneys

• lungs

• heart

• skin

(Heredity and Reproduction)

The Southern Toad and the Copperhead are two animals commonly found in Florida. What is the major difference in the stages of reproduction between toads and snakes?

• Toads lay eggs; snakes do not.

• Toads form larvae; snakes do not.

• Toads form nymphs; snakes do not.

• Toads give live birth; snakes do not.
