Actually ,we have assembled over 105 engineering projects for kids and are adding more as we complete or find more resources.

100 Engineering Projects for Kids

Why list so many engineering projects for kids?

Recent information from the Department of Labor Statistics forecasts that the largest job and demand growth will be in the technology fields between now and 2030.

Did you know the interest in engineering and STEM decreases for girls as they move into the upper grade levels in school?

100 Engineering Projects for Kids use with grades K-12. Wealth of STEM resources with simple to use activities and supplies.

A study conducted by Microsoft in partnership with KRC Research, related to engineering activities and STEM education, indicated that even with increased exposure for females to STEM education, interest in engineering and STEM related jobs did not increase as expected.

The reasons why the interest in STEM dropped off as girls got older:

  • Lack of role models
  • Peer pressure (Perhaps it wasn’t “cool” to be interested in STEM?)
  • Support from parents
  • Support from teachers

One solution even the study students pointed to was providing more hands-on engineering activities and STEM projects!

Below we have 105 engineering projects for kids. Whether you need a group or individual project, there is a variety of engineering projects listed below from which to choose.

Listed first are a few STEM and engineering activities specifically for preschoolers. We encourage you to involve your preschoolers with activities that may seem above grade level, as they will still learn by watching or participating in a small way, i.e. handing an older sibling supplies as needed, letting them take photos of the project along the way, or having them work on their own version of the project.

First, Download the STEM Resource Guide for Parents and Teachers – It’s FREE

I hold a master’s degree in child development and early education and am working on a post-baccalaureate in biology. I spent 15 years working for a biotechnology company developing IT systems in DNA testing laboratories across the US. I taught K4 in a private school, homeschooled my children, and have taught on the mission field in southern Asia. For 4 years, I served on our state’s FIRST Lego League tournament Board and served as the Judging Director.  I own thehomeschoolscientist and also write a regular science column for Homeschooling Today Magazine. You’ll also find my writings on the CTCMath blog. Through this site, I have authored over 50 math and science resources.
