I'm supposed to develop an hypothesis about a certain aspect of a snail's behavior and then devise an experiment that would prove or disprove that hypothesis.
The Attempt at a Solution
Hypothesis: Snails will avoid travelling on hot surfaces.
Experiment: Place a snail on a surface whose temperature is neutral, say room temperature, and then leave the snail free to travel off the neutral surface onto the surrounding surface. The temperature of the surrounding surface would be the variable and the temperature of it can be changed by degrees from hot to cold in relation to the original neutral surface.
If the snail stays on the neutral surface as opposed to venturing onto the warmer surfaces than the hypothesis is true, if not then it's false.
Would this be a legitimate experiment. I'm unsure since the control is sort of integrated into the experiment. Thanks for the advice.
