A student investigated whether ants dig more tunnels in the light or in the dark.
describes the constant
describes the hypothesis
describes the question or problem statement
describes the dependent (outcome) variable
She thought that ants used the filtered light that penetrated the upper layers of earth and would dig more tunnels during the daytime.
describe independent variable
describes constants
describes conclusion
describes the hypothesis
Ten ant colonies were set up in commercial ant farms with the same number and type of ants per ant farm.
describe the constants
describe conclusion
describe independent variable
describe dependent variable
Five of the colonies were exposed to normal room light and five were covered with black construction paper so they did not receive light.
describes hypothesis
describes the independent (test) variable
describes conclusion
describes control variable
Every other day for three weeks the length of the tunnels was measured in millimeters using a string and a ruler. Averages for the light and dark groups for each measured were then computed. The averages are listed in the following chart.
describes the dependent (outcome) variable.
describes hypothesis
describes conclusion
describes independent variable
After analyzing the data and to make sure that the results were accurate, the next step for this student
should be __________.
re-check your measurements
graph the data
repeat the experiment
review the procedures
Since this student is graphing a change over time, which graph type would be most appropriate?
line graph
pie graph
bar graph
pictograph
Zelda noticed a puddle outside her front door. She saw that the puddle got smaller every day, until the 3rd day when it was completely gone. The next week, she noticed the puddle again. This time the puddle was gone the very next day. Since the sun was out the second week but not the first week, Zelda hypothesized that the heat from the sun was the reason for the water evaporating at a faster rate. If she were to set up two containers with equal amounts of water, what would be the best way for Zelda to test her hypothesis?
By placing one container under a lamp and the other not under a lamp, she should then time how long each takes to evaporate.
By placing one under a lamp that has a fan and one not under the lamp or fan, she should then time how long it takes to evaporate
By placing one outside on a sunny day, she should then see how long it takes for it to evaporate. Additionally, she should then wait until there is a cloudy day and put the other container outside, then see how long it takes to evaporate.
By placing one in the living room because that is where the most sun appears in the house and place the other one in the kitchen because there is less light and also a fan that makes it cooler. She could then time how long each takes to evaporate.
Ian proposed an experiment during which he would test the friction created when a skateboard is rolled along a flat surface. He selected three different surfaces (carpet, tile, and concrete) each with three different textures (dry, wet, and icy). His teacher told him that he would need to clarify his experiment before his project would be approved. Which of the following best describes why Ian’s project was rejected?
Ian’s project has two independent variables
Ian does not have a problem that can be tested.
The skateboard will not be able to roll along the carpet
The friction created by a skateboard cannot be measured

Becki, a science fair student, conducts an experiment to see if jumping jacks affect her heart rate more than running. She does 20 jumping jacks in the morning, afternoon, and night and measures her heart rate for 1 minute. Right after her jumping jacks, she runs 1 lap around her neighborhood and then measures her heart rate for 1 minute. Becki’s data is shown below:
Becki concludes that her heart rate is affected the most by running. Why might Becki’s conclusion be incorrect?
Becki should have run first and then do jumping jacks to get more reliable data.
Becki’s heart rate was mostly affected by the time of day, not the type of activity
Becki should have allowed her heart rate to return to normal before going for her run.
Becki should have challenged someone else to do jumping jacks and run with her to get better results.
