Multiple Choice

Gabriel is designing an experiment to see whether sugar or artificial sweetener will attract the greatest number of ants. Which statement best describes why Gabriel should write down his experimental procedure?

• The data will show people which ants are more common.

• The data will help people decide what type of sweetener to use.

• The experiment can be changed by others to get different results.

• The exact experiment can be repeated by others and the results compared.

Multiple Choice

Two scientists were conducting experiments. They each tested the same hypothesis. They made different observations and reached different conclusions. What will the scientists need to do to determine which conclusion is correct?

• Write two conclusions.

• Test other hypotheses.

• Write a new hypothesis.

• Ask other scientists to do the same experiment.

Multiple Choice

Zack and Josh did the same lab activity from their science book. When they compared their data, they found out that they got very different results. What should they do next?

• ask the teacher who is correct

• use Josh’s data because he is a better student

• throw out their data and copy someone else’s data

• review their experiments to see if they can tell what caused the difference

Multiple Choice

Thomas and Julie wanted to find out which material would insulate their teacher's coffee cup and keep the coffee hot for the longest period of time. They first wrapped her cup with bubble wrap and recorded the temperature of the coffee once every 15 minutes for 2 hours. They repeated the investigation, this time using newspaper instead of bubble wrap, but they got the same results for both materials. What could they do to make sure their results are valid?

• Use tea instead of coffee.

• Repeat their investigation.

• Use a different thermometer.

• Conduct their investigation in a colder room.

Multiple Choice

A teacher writes the following note on a student’s experimental design: “You did not identify a control group.” Why is it important to identify a control group?

• Because a scientist must know which variable to use for making a model.

• Because a scientist must form a prediction to see if their results are valid.

• Because a scientist must observe data to make a conclusion based on evidence.

• Because a scientist must know what normally occurs so they can compare this to what they are testing
