What Does STEM Look Like in Middle School?

Middle school is an exciting time for the STEM classroom because this is when you can start introducing “real” science and STEM into the classroom.

Equipment can be more sophisticated and the challenges can be more robust.

I like to encourage every middle school STEM activity to solve a real-world problem. To illustrate some concepts, sometimes the real-world problem has to be a bit of a stretch, but that only adds to the fun.

A middle school STEM activity should have a problem to solve, an open-ended solution, and a discussion on why or why not that solution worked to solve that problem.

Middle school STEM activities can also help introduce new concepts or tools in the science lab.

How to Bring Valentine’s Day into Middle School STEM

Middle school science can get a little boring, as things get more complicated. But you can lighten up the work by bringing in more hands-on activities and making some experiments seasonal.

For Valentine’s Day, you can learn using candy, chocolate, or hearts.

Maybe the kids can figure out how to make a working model of a heart, or they can find out how to create sustainable crystals that replaces diamond mining.

There is almost no end to what you can add in for Valentine’s STEM activties!
