Mark wants to find out how the surface of a ramp affects the speed of a toy car. He wants to know whether the cars will travel faster down a smooth surface or a rough surface. To gather data to answer his question, what must Mark do?

• conduct an experiment

• draw a conclusion

• make a prediction

• communicate results

Evan wrote down some notes about ways he thinks scientists conduct investigations.

• Make a hypothesis

• Plan and conduct an investigation

• Analyze data and communicate results

• Change results to match the hypothesis

Which of Evan’s notes is NOT a way scientists conduct investigations?

• make a hypothesis

• plan and conduct an investigation

• analyze data and communicate results

Carol performed an experiment in which she tested how mass affects the distance 5 different model airplanes can travel. She tested each airplane once. She noticed that the results for Airplane C were very different from the other results. What should Carol do to verify the results of her experiment?

• conduct the experiment using model rockets instead

• repeat the experiment more times using the same airplanes

• ignore the data for Airplane C and use her other results

• change the experiment to use different airplanes

Jose observes two bird feeders in his backyard. Each bird feeder has a different type of seed. Jose records the number and type of bird at each feeder each day for five days. He chooses to display his data in a bar graph. Why is a bar graph the best choice for the data?

• It can show each type of bird by using symbols.

• It can easily compare the number of birds at each feeder each day.

• It can show how the number of birds changes over time.

• It can show what percentage of each type of bird is at the feeders.
