Project Selection Work with your child to select a topic interesting to them (e.g., paper airplanes) Work with your child to select a topic 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?” A: “They fly!!!”

Project Selection Q: “How do I change what paper airplanes do?” A: “Perhaps I can change the mass of the plane?” So now you have your experimental question! “Does changing the mass of a paper airplane effect how far it flies?”

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

Variable Identification Controlled Variables – things that might change but shouldn’t because they might effect the results; sometimes referred to as constants. Controlled Variables – things that might change but shouldn’t because they might effect the results; sometimes referred to as constants. Type of paper Type of paper Airplane shape Airplane shape Launch style Launch style Winds aloft Winds aloft Others? Others?

Hypothesis An Educated Prediction An Educated Prediction If ……. then……… If ……. then……… If (independent variable changes this way), then (the dependent variable changes this way) If (independent variable changes this way), then (the dependent variable changes this way) If the mass of the paper airplane is increased, then the distance the plane flies will decrease If the mass of the paper airplane is increased, then the distance the plane flies will decrease

Materials and Procedure Use things you have already Use things you have already Be creative with existing materials Be creative with existing materials Procedures should be clear and concise Procedures should be clear and concise Perform multiple trials Perform multiple trials Repeatable by others Repeatable by others
