Student+D+Hairspray+7

Does someone wearing hairspray attract more insects than someone who is not?

1. A hypothesis: A person who is wearing hairspray attracts more bugs than a person who is not.

2. Explain how to set up the experiment


 * 1) Brainstorm a list of all the variables that must be kept constant during the experiment: Same age, same hair colour, same gender, same types of insects, same type of hairspray, same room, same temperature, same liking for insects, same amount of insects in each room
 * 2) Include identification of the independent variable: The independent variable is amount of hairspray being used.
 * 3) The dependent variable: The dependent variable is the insects being attracted to the hairspray.
 * 4) Identify the control group: The control group is the group without hairspray
 * 5) Identify the experimental group(s): The experimental groups of this experiment are the groups with hairspray.

3. Provide enough details for someone else to set up your experiment: First, you would collect one hundred people of the same gender, the same age, and the same hair colour. Next, split up the one hundred people into four groups. Twenty-five people in each group. In group one, no one will have hairspray. In group two, the people will have a weak amount of hairspray. In group three, people will have a medium amount of hairspray. In group four, the people will have a high amount of hairspray. Put each group in a room full of insects. Check after an hour to see which group attracted the most insects.
