![science experiments for high school Collage of high school science fair projects, including 3D printed cars and a DIY vacuum chamber](https://www.weareteachers.com/wp-content/uploads/high-school-science-fair-projects.png)
The cool thing about high school science fair projects is that kids are old enough to tackle some pretty amazing concepts. Some science experiments for high school are just advanced versions of simpler projects they did when they were younger, with detailed calculations or fewer instructions. Other projects involve fire, chemicals, or other materials they couldn’t use before.
Note: Some of these projects were written as classroom labs but can be adapted to become science fair projects too. Just consider variables that you can change up, like materials or other parameters. That changes a classroom activity into a true scientific method experiment!
To make it easier to find the right high school science fair project idea for you, we’ve rated all the projects by difficulty and the materials needed:
Difficulty:
- Easy: Low or no-prep experiments you can do pretty much anytime
- Medium: These take a little more setup or a longer time to complete
- Advanced: Experiments like these take a fairly big commitment of time or effort
- Basic: Simple items you probably already have around the house
- Medium: Items that you might not already have but are easy to get your hands on
- Advanced: These require specialized or more expensive supplies to complete
