Summer Science Scientific Method Review Worksheet - Engage students with fun, real-world scenarios to practice hypothesis writing and experimental design.

- If you wrap your snacks in aluminum foil, then they will not be stolen by seagulls at the beach.
- Independent Variable (underlined once): wrapping snacks in aluminum foil
- Dependent Variable (underlined twice): seagulls stealing snacks

- If you ride a bike with larger tires, then you will go faster even if you pedal at the same rate.
- Independent Variable (underlined once): bike tire size
- Dependent Variable (underlined twice): speed of the bike

- To test whether sharks are more attracted to people in black wetsuits: Set up controlled observation zones in shark-prone waters where human-shaped decoys or swimmers wear either black wetsuits or non-black attire. Keep distance from shore, water temperature, time of day, and decoy movement constant. Record frequency of shark approaches or interactions per suit color. The independent variable is wetsuit color; the dependent variable is number of shark interactions. Controls include using identical decoy shapes, consistent environmental conditions, and avoiding bait or scents.
