How well can mealworms climb up a tin foil plate vs. a cardboard plate

Goal: To discover whether or not the mealworms would be able to climb up the aluminum pan as easy as a cardboard plate or vice versa.
Materials: Aluminum pan, paper plate
Hypothesis: On the tin foil we believe that the mealworm will slip and slide everywhere. We believe that the beetle will have an easier time walking on it but will still have more difficulty than on the cardboard
Procedure: We placed the mealworms and beetle on a pie plate. We allowed them to attempt to walk for sixty seconds, and then removed them both and placed them on a paper plate.
Observations: The Mealworm and beetle were both slipping quite a lot on the tin foil and having difficulty walking. The mealworm crawled toward the edge of the aluminum pan, and used it to move by squirming around, we noticed that he seems to be attempting to hod on with hes front legs while using his back legs to attempt to push himself forward. After placing them on the paper plate instead we noticed that they are able to climb it with ease and moved around very quickly.
Results: The mealworm and beetle were unable to climb the aluminum pan, as when viewed under a microscope there is nothing to grip onto, however, under the microscope we a
Independent Variables: Type of plate used,
Dependent variables: Mealworm's reaction to experiment
