Choosing your project.
Your science fair project will answer a question. You probably ask questions all the time. You just
never thought of them as science fair projects! Are cats smarter than dogs? Does washing your hands
really get rid of germs? Why does your Mom say she's cold when you're hot? How warm is global warming?
Is that TV commercial true?
Good Places to Get Science Fair Ideas
Your house or apartment, especially the kitchen, bathroom, laundry, basement, garage.
Your pets. Their food, bed, or flea stuff. Also at your veterinarian's office.
Your yard. Good for ideas about how things grow.
TV, especially news, science and nature programs. You can also try to prove if what a commercial says is true.
Newspapers. Current events about health, the weather and the environment are good sources of questions.
Library. Look at science books and magazines. You might find an interesting subject.
