Do fruit flies

really like fruit?

Question Do fruit flies really like fruit? If not

what food do they like best?

My hypothesis….. They will prefer any sweet smelling

thing I put in there.

VariablesIndependent V.: Type of food Dependent V.: Number of fruit flies on food

What I used for this experiment

Assortment of food Glass tank Fruit flies Patience

Procedure I waited for the flies to reproduce so I

would have plenty of test subjects. Then I put about 40 in the glass tank along with 4 specimens of food in each corner. The flies I put in the center each time.
