The cool thing about high school is that kids are old enough to tackle some pretty amazing science experiments and projects. 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 weren’t old enough to use before.
Many of these projects can be used as classroom labs or science fair projects. Feel free to adapt them as needed for students’ individual projects, or use them as full-class activities. However you plan to use the projects, just consider variables that you can change up, like materials or other parameters.
To make it easier to find the right high school science experiment 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
Materials:
- 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
