9. Students working on a science research project are testing batteries in order to determine which brand will last the longest. The students placed two new Brand A batteries into a flashlight. The students placed two new Brand B batteries into a remote control truck. Both devices were turned on, and the students recorded how long each device ran on the batteries. Students repeated this experiment once a week for ten weeks. Although the students collected and recorded their data, they realized they had a major flaw in their experimental design. What was this flaw?
A. The students did not collect enough data.
B. The students tested only two brands of batteries.
C. The students used two different devices to test the batteries.
D. The students did not run their experiment over a long enough time.
SC.8.N.1.1
10. A group of students is participating in a science project to determine what factors affect the severity of a skin burn more, the temperature of the water or how long the hot water stays on the skin. The students use small potatoes to model the skin and placed 6 potatoes each in hot water at 50, 75 and 100 degrees Celsius. Which statement best explains why the temperature of the water is the test variable (independent variable) in this project.
A. The students are placing potatoes in the water that is at specific temperatures.
B. The students heated all of the water samples to the same temperature.
C. The students are intentionally changing the temperature of the water.
D. The students are recording the temperature of the water.
