Match

Match the following

Experimental Group

Independant Variable

Dependent Variable

Control Group

The group that receives the variable being tested and then can be used as a standard of comparison

Factor in an experiment that a scientist purposely changes.

Factor in an Experiment that a scientist observes in response to the independent variable

Match

Match the following

Variable shown on the X-axis of a graph

Variable shown on the Y axis of a graph

Variable in an experiment that a scientist purposely keeps the same.

Independant

Dependant

Controlled

5

Dropdown

Theory vs Law True and False:

Theories describe things and laws explain things.

Theories change because new technology improves our ability to observe the natural world.

Laws do not change with new evidence.

Theories become laws

Multiple Choice

Sabrina wants to test which brand of popcorn pops the most kernels. She picked a Giant Eagle brand, Orville Redenbacher, and PopSecret. All three bags started with the same number of kernels. She popped each for 3 minutes in the same microwave, and then counted the number of kernels left over. What is her independent variable?

1

Number of kernels left over

2

Brand of popcorn

3

Number of kernels before popping

4

Length of time cooking

Multiple Choice

Kira wants to test which type of soda creates the biggest foam explosion when adding a Mentos candy. She chose Sprite, Coke, and Mountain Dew. One at a time, she added a single Mentos candy and measured the height of the foam eruption. Mountain Dew created a foam eruption of 7 inches. Coke and Sprite tied at 5 inches. What is her dependent variable?

1

Brand of soda

2

Number of mentos candies used

3

Heigh of the foam eruption

4

Temperature of soda

A scientific law explains why something happens, while a scientific theory explains what happens

4

Both scientific theories and scientific laws explain why something happens

14

Multiple Choice

What is peer review?

Multiple Choice

SpongeBob noticed that his favorite pants were not as clean as they used to be. His friend Sandy told him that he should try using Clean-O detergent, a new laundry soap she found at Sail-Mart. SpongeBob made sure to wash one pair of pants in plain water and another pair in water with the Clean-O detergent. After washing both pairs of pants a total of three times, the pants washed in the Clean –O detergent did not appear to be any cleaner that the pants washed in plain water. What is the control in this experiment?

Type of detergent

2

Pants washed in plain water

3

Pants washed in Clean-O detergent

4
