Work with your child to select a topic Work with your child to select a topic interesting to them (e.g., paper airplanes)interesting to them (e.g., paper airplanes)
Ask, “What does the topic do?”Ask, “What does the topic do?”Q: “What do paper airplanes do?”Q: “What do paper airplanes do?”
A: “They fly!!!”A: “They fly!!!”
Project SelectionProject Selection
Q: “How do I change what paper airplanes Q: “How do I change what paper airplanes do?”do?”
A: “Perhaps I can change the mass of the A: “Perhaps I can change the mass of the plane?”plane?”
So now you have your experimental question!So now you have your experimental question!
““Does changing the mass of a paper airplane Does changing the mass of a paper airplane effect how far it flies?”effect how far it flies?”

Independent Variable : The variable Independent Variable : The variable changed by the experimenter.changed by the experimenter.
Mass of the paper airplaneMass of the paper airplane
Dependent Variable: The variable Dependent Variable: The variable that changes as a result of IV change that changes as a result of IV change (the change which is measured)(the change which is measured)
The distance the plane fliesThe distance the plane flies

Controlled Variables – things that Controlled Variables – things that might change but shouldn’t because might change but shouldn’t because they might effect the results; they might effect the results; sometimes referred to as constants.sometimes referred to as constants.
