How to Make Middle School Science Fun

Middle school science starts to get into the whys, hows, and whats of science. It’s not just about fun experiments anymore. Middle school is when a lot of kids start to lose interest in science because it takes work.

But just because you have to teach specific concepts and themes in middle school doesn’t mean you can put a bit of hands-on science fun into the middle school science lab.

We like to do seasonal twists on our middle school science experiments. For Valentine’s Day, use valentine candy, turn things pink, or learn about the heart! These silly additions will make science a bit more fun, and may help keep kids interested in science even through high school.
