Science for Kids: 28+ STEM Activities To Do at Home

Step-by-step instructions and materials lists for family-friendly science activities.

May 5, 2020

These easy-to-follow science activities for kids were put together for school-based Family Science Night events with support from UL, and they’re now available for parents to download directly and use at home!

The 28 activities cover several scientific disciplines, including the physical science, engineering, and life sciences. Each activity includes a list of materials, step-by-step instructions, photographs, and a section to learn more about the concepts in that activity, plus a Science Investigator’s Journal to record observations and results from the activity.

There are also two extended activities to do at home—codebreaking and geocaching—and a roundup of 10 STEM careers for kids to explore.
