State Science Test Review Part 3

Maurice followed these steps of an investigation:

Step 1. Collect five objects made of different types of metal.

Step 2. Place them on a large laboratory table.

Step 3. Touch each metal object with a magnet and lift slowly.

Step 4. Record observations.

Which of the following statements is Maurice most likely testing?

• All types of metal are attracted to magnets.

• Each magnet can lift the metal object to the same height.

• Larger magnets can pick up heavier metal objects than smaller magnets can.

• Heavier metal objects are more attracted to magnets than lighter metal objects are.

Lucas told his mom he wanted to know how tall the members of his family are. Each family member takes turns measuring each other. His mom is 5 feet 2 inches, his dad is 6 feet, his sister is 3 feet 3 inches tall and he is 4 feet 7 inches tall. What could Lucas do with this data to make it easier to read and analyze?

• ask a question 

• make a prediction

• draw a conclusion 

• create a data table

Tyrone is conducting an experiment that investigates the heart rates of girls and boys in fifth grade. He measures the heart rates of 25 subjects every day for one week. At the end of the week, he divides the data into two groups according to gender. He then analyzes the data to find the average heart rate of each group. What is the purpose of forming a conclusion at the end of the experiment?

• The conclusion summarizes the results of the experiment.

• The conclusion states a theory or law based on the results.

• The conclusion asks new questions about the subject matter.

• The conclusion reports the way the experiment was performed.

Martha followed these steps of an investigation:

Step 1: Gather 3 microwavable cups the same size and material and label the cups A, B, and C.  

Step 2: Add 25 mL of water to Cup A, 50 mL of water to Cup B, 100 mL of water to Cup C.

Step 3: Heat each cup for 1 minute in a microwave and measure the temperature of the water.  

What is the best choice for what she should do after Step 3?

• Write a conclusion.

• Ask a new question.

• Add more water to each cup.

• Record the temperatures she observed.

Walter runs on his school’s track team. He knows that when he runs in the 100-meter dash, his heart rate goes up. Walter wonders if his heart rate goes higher when he runs further. How could Walter find the answer to his question?

• run a 100-meter dash and measure his heart rate

• run a 200-meter dash and measure his heart rate

• run a 100-meter dash and a 200-meter dash and measure his heart rate

• run a 100-meter dash and a 200-meter dash and see which one makes him most tired
