Inexpensive Science Fair Experiments and Project Ideas

A science fair project does not need to cost a lot of money. A project can easily be done for under $30.00, including the project board and crafting supplies. You can probably spend even less. Trust me, I have done it.

Tips to Keep it Inexpensive

1. Come up with an idea from items you already have.

Experiment with your favorite cookie recipe.
Water is amazing all on its own.
Get some eyedroppers and wax paper and see what it does.
Explore the absorption or strength of paper towels.

2. Pick a topic that is about an everyday science concept.

Why do we use salt on sidewalks?
Explore which fruits will float with or without the peel.
What type of milk makes the best butter?
Does the type of salt affect the thickness of ice cream?
Use coins for chemistry and motion experiments.

3. Get creative with your idea.

You can do a science fair project with a sled, snow, and a hill. Increase the weight of the sled and measure the distance the sled travels. Just start with one person in the sled, then two, and then three.
Test different cat toys to see how long your cat plays with each of them or your dog.
What can you create with Matchbox Cars?
Which paper towel is the strongest?
What is your favorite sport? Can you think of an experiment?
Think of some of your hobbies. What can you come up with?
Head to the Dollar Store and look around. Glow Sticks, candy, marbles, flashlights, and more.

Project ideas are endless. Anything can be turned into an investigation.
