Titles can also be catchy and interesting. For example, let's say you were testing flashlight batteries to determine which will last longest, to help consumers make a choice. You can use a witty title such as "Are You in the Dark when Choosing Batteries" to be entertaining and tell what the experiment is about.

So the title for the snake experiment, for example, could be "The Importance of Color in Determining the Attack Habits of Snakes" or "How Coloration Determines the Attack Habits of Snakes." The title of any experiment should be a one phrase summary of what the experiment is measuring or testing.

I can only concur with the above editors. You have been given the hypothesis for both experiments, and then the variable is the factor that is changed in the experiment. Every scientific experiment should have a control, which is meant to show that the results of the experiment is due to the variable that you change and not anything else.

I agree with #2 on the hypotheses and variables. For the flashlight test, you control it by testing just one variable at a time. For instance, you try new batteries with the old bulb. If that doesn't work, then you try changing the bulb, but you don't do both at once. For the snake experiment, the control is the plain brown snakes that were put out along with the colorful ones. The controlled variable is coloration, and the control snakes -the brown ones- are there to see if animals will either avoid or attack any snake they see, regardless of color.

Are you asking about the flashlight one?

You've already got the hypothesis written out.  The independent variable is the one you change -- the batteries.  The dependent is the one that is supposed to change based on the change in the independent variable.  In this case, it's whether the flashlight turns on or not.

If you're doing the snake one, the independent variable is the presence or absence of color on the artifical snakes.  The dependent variable is the number of attacks on the snakes.
