What does the effect of salt have on the melting of ice.|||the control group would just be a piece of ice in a specific dish at the same temperature each time you perform the experiment. one thing too you may want to think about is to make the ice from the same amount of water. there's a lot of variables to think about like temperature, size of ice or water it's made from, the dish the ice sits in, etc.
good luck.|||Well any ice that DOES NOT have any salt on it is the control group (also known as placebo)|||The control would be where the dependent variable has a change of 0. You are testing whether salt affects the melting point, so the control is what the melting point is when there is no salt present.|||Set up 2 experiments, exactly the same. One add salt to the ice and the other, DONT add salt. then you monitor the melting rates of the ice in the two setups. The one without salt is the control. You'll compare the results of the experimental (with salt) to the control (no salt)
