What was the Independent Variable?
Students wanted to see if the type of material affected the temperature after being placed under a heat lamp for 10 minutes.
What is the dependent variable for this investigation?
Type of material (rocks, sand etc)
Temperature after 10 minutes
Time under the lamp
Heat lamp, amount of material
A scientist hypothesizes that the temperature at which an Alligator's egg is incubated will determine whether the alligator will be male or female. The independent variable is...
the male alligators
the incubator
the gender of the alligator
the temperature
In this graph, what is the independent variable?
Population
Day
Species 5
In this graph, what is the dependent variable?
Walla Walla Island
Time
Number of Deer
Xavier’s team designed an experiment to answer the following question. How does the surface of a ramp affect how far a toy car rolls?
Which factor should Xavier change in the experiment?
the kind of car
the height of the ramp
the surface of the ramp
Melika made a model to help understand why craters on the moon are different sizes. She represented the moon’s surface with a pan of flour. Melika represented objects that hit the moon with marbles. She thinks that dropping marbles from a greater height will make the crater’s diameter larger.
What should she change in her experiment to test her hypothesis?
the weight of the marbles
the kind of flour in the pan
the height she drops the marbles from
the size of the marbles
1. Place 20 spinach leaves into the container
2. Put the carbon dioxide sensor in and close the container
3. Turn on the light and wait 20 minutes
4. Check the carbon dioxide levels
5. Repeat experiment with different amounts of time under the light
What is the Dependent Variable?
Amount of Light
Amount of Spinach
Distance from the light
Amount of Carbon Dioxide
Choose the BEST hypothesis for the following:
Annabelle wanted to know if Bic pens would last longer if she used cardboard rather than copy paper. She used 5 Bic pens on cardboard and 5 Bic pens on copy paper. She used the same color ink in every pen.
If she uses Bic pens on cardstock her pen will last longer.
The Cardstock will last longer than copy paper.
If she uses bic pens on copy paper, then the bic pen will write for a longer amount of time.
Since this student is graphing a change over time, which graph type would be most appropriate?
line graph
pie graph
bar graph
pictograph
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
