Question

1. you notice that the strawberries in your garden all have tiny bitemarks in them. you hypothesize that rabbits are the culprits, so you put a wire fence around half of the strawberry patch. list the independent variable, the dependent variable, and 3 possible controlled variables in this experiment.

Explanation:

• Independent Variable: The factor manipulated in the experiment. Here, it's the presence/absence of the wire fence (specifically, putting the fence around half the patch, so the fence (or the protection it provides) is what's changed).
• Dependent Variable: The factor being measured or observed, which depends on the independent variable. Here, it's the presence/absence of bitemarks on the strawberries (or the number of bitemarks).
• Controlled Variables: Variables kept constant to ensure a fair test. Possible ones:
• Type of strawberry plants (same variety to avoid differences in susceptibility).
• Amount of water given to the strawberry patch (so watering doesn't affect bitemarks).
• Amount of sunlight the strawberry patch receives (so light doesn't influence rabbit behavior or plant health affecting bitemarks).

Answer:

• Independent Variable: Presence/absence of the wire fence (or "wire fence (protection) around the strawberry patch")
• Dependent Variable: Presence/absence (or number) of bitemarks on strawberries
• Controlled Variables:
• Type of strawberry plants
• Amount of water given to the patch
• Amount of sunlight the patch receives
