100 Engineering Projects For Kids

100 Engineering Projects for Kids
Actually we have assembled over 105 engineering projects for kids and are adding more as we complete or find more resources.
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?
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
The sponsor for our guide is The STEMKids. TheSTEMKids is about empowering young learners to blossom into curious and adventurous learners. Our science toys for kids is a product line that is specifically engineered to maximize hands-on learning, the best type of learning there is!

4th Grade NGSS STEM Challenges Any Time 4th Grade NGSS STEM Challenges 4th Grade NGSS STEM Challenges
I got a fantastic question from a 4th grade teacher in my inbox the other day. it read:.
“I am hoping to teach a STEM lab starting in October for 4th grade and will need to focus on activities that support and teach 4th grade science standards. Do you have activities that specifically support the NGSS for 4th grade? I have discovered many bundled ideas that claim they support 4th curriculum but then there are only 1-2 activities that actually deal with the specific 4th grade standards making the resource not fully usable. The “engineering” standards are generally always included, but the activity itself has nothing to do with the specific energy standards for 4th grade. Thank you for your time!”
So thank you, Joyce, for reaching out! It can be annoying to figure out which Next-Generation Science Standards STEM Challenges are aligned with, I know. And for me, I’ve always been a hard-liner with the way I tag my resources for alignment. I only tag the engineering standards because that’s what the challenge itself thoroughly addresses.
I recently went live on my Facebook page to talk through all of this. I’ve embedded that video here, and everything discussed is linked below. Don’t hesitate to reach out if you have any questions!
Even though my STEM challenges come with content-connection suggestions and often also include related video links, activities, and handouts, it’s up to the teacher to decide to use those — or not. So, I’ve tended to err on the side of being overly cautious with standards tags; I never want to mislead or confuse anyone.
That said, there are a LOT of standards connections across many grade levels with the suggestions included in my resources, and I always include thorough previews of my resources, plus video walk-throughs to take the guess work out for you.
So with that, let’s check out the 4th Grade NGSS Topics and which STEM Challenges are aligned — beyond the engineering strand.
Note: This list addresses only 4th grade NGSS connections. Many of the challenges not on this particular list align well with other 4th grade standards in math and ELA.
4th Grade NGSS: Energy
Best connections:, apple annihilator (wrecking ball), wicked-fast water slide (potential/kinetic energy), keep it cool / make it melt (heat transfer), planetopia plants (energy from sun), sled & slope / sleigh & slope (potential/kinetic energy), carrot carriage (potential/kinetic energy), looser connections:, wings wanted (paper airplane), treat toss (catapult: potential/kinetic energy), cupid’s quiver (bow & arrow: potential/kinetic energy), build a boat / mini mayflower (wind energy, if using the sailing speed test).

4th Grade NGSS: Waves

4th Grade NGSS: Structure, Function, and Information Processing

Create-ure (creating an animal with features that support survival, growth, behavior, reproduction)
Planetopia plants (creating plants with features that support survival needs), amphibious phones (post-challenge extension: designing cases for different classes of animals and relate those features to their survival needs), wings wanted (if after you perform the paper airplane test, you extend with research or lessons on bats and how their anatomy helps support their survival), creature catcher (spider web challenge: extend with a study of spiders’ anatomy, functions, and behaviors that support survival), bone bridge (skeletal system or vertebrates vs. invertebrates, comparing structure and function), groundhog graffiti (light reflected from objects enters the eye — looser connection), 4th grade ngss: earth’s systems: processes that shape the earth, best connections, planetopia parcels (landforms), wild weather shelter or protect-a-pilgrim (i prefer wild weather shelter for 4th as it relates more throughly to reducing impacts of earth’s processes on humans), looser connections, card towers , apples aloft , or cards in the clouds (building towers resistant to earthquakes), new earth city (students build a “perfect” city on a fictional planet), create-ure (if you extend with fossil record activity).

The Verdict?
The best-aligned bundle for 4th grade teachers is the planetopia project . each challenge in that bundle addresses multiple 4th grade science standards., the others each challenge mentioned is included in a bundle 5-pack. the halloween bundle included 4 challenges on the list, so it’s another contender..

But remember, all the challenges on this list align with the engineering strand.
And just because a challenge didn’t make this science connections list, doesn’t mean it won’t align beautifully with 4th grade standards in math and ELA!
