These awesome spring STEM activities below are great for a range of kids from ages 3 to at least 9 to 10!  Think preschool, kindergarten, and elementary age kids.

Most spring STEM activities can be adapted to fit your kids’ unique interests, needs, and abilities with just a bit of tweaking.  You can make all of these spring STEM activities and plant experiments work for you!

If you have kids who love to explore, discover, get dirty, create, tinker, and build, this is the STEM resource for you! However, if you are new to STEM or science, technology, engineering, and math, we have a few additional STEM resources you can check out below.


Science activities and experiments, and STEM challenges are awesome for young kids!  Kids are naturally curious and looking to explore, discover, check out, and experiment to find out why things do what they do, move as they move, or change as they change!

Our science activities are visually stimulating, hands-on, and sensory-rich for discovery and exploration of simple concepts for young learners! My son is 8 and we started around 3 years of age with simple science activities for kids. Here’s our very first experiment!

All our science activities and experiments are designed with you, the parent or teacher, in mind!  Easy to set up, quick to do, most activities will take only 15 to 30 minutes to complete and are heaps of fun!  Plus, our supplies lists usually contain only free or cheap materials you can source from home!
