How Scientists Think

Looking for a project to do for your science fair? Try these downloadable science fair kits. They provide everything you need to get started thinking like a scientist, from forming a question to communicating results of your experiment.

Remember, science is about asking questions and that there can often be many answers to a single question. To figure out which answer is most correct, scientists follow a process called the Scientific Method.

The Scientific Method is a series of steps that helps scientists identify a question, think of a possible answer (the hypothesis) and then use experiments to test the hypothesis to see if it is true.

The important thing to remember is that all scientists will often try many experiments until they can be sure a hypothesis is true or not true. Once a conclusion is made, scientists report their results in either a written report or visually on a display board.

Is Your Home A Pill Bug Habitat?

Pill Bug Box

Observe the pill bug in all its glory (or at least its preferred habitat). In this investigation, you will create a controlled environment, a pill bug habitat. Then you'll select different changes to test to determine the pill bug's preferred habitat.

Repelling Ants

There are many types of ants and many ways for them to infest your home. In this project, you will test how effective one or more natural repellents are at preventing ants from entering your home.

Age Range: Third Grade (with adult supervision) to Eighth Grade

Time Required: 4 days to 2 weeks, depending on the questions you ask.

Cost: Minimal - most materials are readily found in many home kitchens.

Which Came First: The Fly or The Egg?

Fruit Fly

Fruit flies are not only pests but they are also incredibly helpful in scientific research. For this project, you will start by observing the fruit fly life cycle. Then you will follow the scientific method to test how temperature affects fly development during their life cycle.

Age Range: Fourth Grade to Eighth Grade

Time Required: 2 weeks to 1 month or longer (if you choose).

Cost: Minimal - most materials are readily found in many home kitchens.
