Multiple Choice

Destiny conducted an experiment to test which of four types of batteries lasts longest in a flashlight. She used four identical flashlights and placed a different type of new battery in each flashlight. She turned the flashlights on at the same time, and she recorded the time when each flashlight stopped giving off light. What is the dependent variable in this experiment?

• The type of battery used

• The type of flashlight used

• The total amount of time each battery lasts

• The starting time when each flashlight is turned on

Multiple Choice

Using the table, which of the choices below places the variables of this experiment in their right function?

• A

• B

• C

• D

Multiple Choice

Which conclusion did the biologist most likely make from the data shown in the table?

• A

• B

• C

• D

Multiple Choice

A student wants to determine the effect of soil type on plant growth. He sets up three pots as shown below. How could this experiment be improved?

• A. All three pots should have the same kind of soil.

• B. All three pots should have the same kind of seed, the same amount of light, and the same amount of soil.

• C. The three pots should have different amounts of water.

• D. There is nothing wrong with this experiment.

Multiple Choice

Which procedure determines whether water temperature affects the weathering of sedimentary rocks?

• A. Test 3 identical sedimentary rocks, 1 in hot water, 1 in cold water, and 1 in room-temperature water.

• B. Test 3 identical sedimentary rocks in 1 water temperature.

• C. Test 1 crushed sedimentary rock in warm water and 1 whole sedimentary rock in cold water.

• D. Test 3 identical sedimentary rocks, 1 in an acid, 1 in a base, and 1 in water.

Multiple Choice

Duckweed is a plant that grows on the surface of ponds. Duckweed has leaf-like structures called fronds. A student conducts a lab investigation on duckweed growth and creates the graph shown above. Which of these is a valid conclusion based on the data from this investigation?

• A. The number of fronds increased quickly between days 2 and 4.

• B. The number of fronds increased quickly because the plant has a short life span.

• C. The number of fronds is related to the number of hours of sunlight each day.

• D. The number of fronds increased at a constant rate between days 1 and 5.

Multiple Choice

Scientists have studied the melting glaciers as evidence of global warming. One team of scientists predicts that the glaciers are melting at an accelerated rate. The scientists collect the same types of data on the same glaciers on the same dates each year for ten years. The scientists conclude that the glaciers have decreased in mass and increased their velocity toward the sea each successive year. Which of the following statements best evaluates the process that the scientists used?

• A. The process is a flawed experiment because the variables are not controlled.

• B. The process is a valid experiment because there is an independent variable and a test variable.

• C. The process is a flawed investigation because the investigators did not form a hypothesis.

• D. The process is a valid investigation because scientists used systematic methods for collecting and analyzing information.

Multiple Choice

Some students hypothesize that heating a mixture of any substance and water will always increase the amount of the substance that will dissolve in the water. The table shows results of an investigation testing this hypothesis. The results for which of the substances tested weaken this hypothesis?

• A. Substance W

• B. Substance X

• C. Substance Y

• D. Substance Z

Multiple Choice

Which is the dependent variable, and what is the trend in the graph?

• A. Solubility; as temperature decreases, solubility increases.

• B. Solubility; as temperature increases, solubility increases

• C. Temperature; as temperature increases, solubility increases

• D. Temperature; as temperature decreases, solubility decreases.

Multiple Choice

The table shows the results of an experiment with bread molds. According to the data, what are the best conditions for growing mold?

• B. cold temperature and high humidity

• C. warm temperature and low humidity

• D. warm temperature and high humidity

Multiple Choice

Kyra is studying the different factors tha can affect the growth of a plant. Based on her research, she thinks that the amount of water, the exposure to sunlight and the type of fertilizer may contribute to the growth of the plant. What should Kyra do to test the effect of sunlight and get accurate result in her experiment

• A. Change the amount of water and keep the fertilizer and the amount of sunlight the same.

• B. Change the type of fertilizer and the amount of wter and the same tiem and keep the amount of sunlight the same.

• C. Change the amount of sunlight by placing the plants in different locations and keep the amount of water and the type of fertilizer the same.

• D. Change the type of fertilizer, the amount of water, and the amount of sunlight at the same time.

Multiple Choice

Students made an electromagnet by wrapping a wire in loops around an iron nail and attaching the wire to a battery. The students conducted a test to learn how the number of wire loops affected the number of paper clips held by the electromagnet. The table shows the results. Based on the information from the table, which of the following is the outcome (dependent) variable in this experiment?

• A. The number of wire loops wrapped around the nail.

• B. The number of paper clips held by the electromagnet.

• C. The material the nail was made of.

• D. The size of the battery.

Multiple Choice

Which of the following is most likely responsible for differences in the data?

• Group 2 calculated incorrectly

• Group 2 measured incorrectly

• Group 3 measured incorrectly

• Group 3 recorded data incorrectly
