What Are Easter STEM Activities?
STEM stands for science, technology, engineering, and math. Easter STEM activities encourage kids to explore these concepts through hands-on challenges using common Easter materials like eggs, candy, and baskets.
Kids become engineers as they design structures, test forces, experiment with motion, and improve their designs through trial and error.

Featured Easter STEM Challenge: The Great Easter Egg Tower
One of our favorite Easter engineering activities is the Easter Egg Tower Challenge.
In this activity, kids design and build the tallest tower possible using spaghetti noodles that can support a plastic Easter egg.
This challenge encourages kids to test ideas, work within limits, and redesign their structure to make it stronger.
Challenge
Can you build the tallest spaghetti tower that can hold an Easter egg on top?
Supplies
• 20 sticks of dry spaghetti
• 1 yard (3 feet) of string
• 1 yard (3 feet) of tape
• 1 plastic Easter egg
Rules
- Use only the materials provided.
- Build the tallest tower possible.
- The egg must sit on top without falling.
- You have 18 minutes to complete the challenge.
Encourage kids to measure their tower and record their results.

It is nearly impossible to find where to actually get a download link. Everything goes to the “Start Download” button which then downloads malware (Ask comes along with it). It makes an excellent website a really difficult site to use.
I am sorry those are ads I believe, and I don’t have a ton of control over there placement or when they show up. My download boxes are black rectangles that are pretty big!
I am trying to get a copy of the Easter STEM Activity Cards.
It is saying Link not found.
Hi! I just checked and am not seeing the error can you email me please, sarah@littlebinsforlittlehands.com
