3. Flotation Device for Action Figure

Ask your child to build a flotation device for their action figure and see if it will float. (3rd – 5th grade level suggested)

You can also ask them to log their results with different types of flotation devices they’ve built, to make it a little more challenging, as well as teach them how to record the results of experiments. Included are examples and printing instructions, including a video.

You can purchase this plan at Teachers Pay Teachers or do your own version of it. It’s pretty simple!

Supplies needed for activity:

You will also need plastic bags, tape, action figures, and a plastic tub for water.

4. Rai nbow Water Walking

The Rainbow Walking Water experiment is a practical application of science that can be used in educational settings to teach children about topics such as absorption, color mixing, and the properties of water. It provides a hands-on learning experience that helps to foster curiosity and a deeper understanding of scientific concepts.

This is a fun and colorful science experiment your kids will love!

Supplies needed for activity:

5. Egg Drop Project

If you’re unfamiliar with this popular STEM activity, the challenge is for kids to design a contraption using various materials (usually recyclables) to protect a raw egg from a high fall.

They will learn to be creative and use available resources of their choice to attempt the challenge. There will be lots of laughs with this one, as well as a few ‘oopsies!’

6. Paper Plate Marble Maze

In this STEM challenge for kids, children will create a paper plate marble maze game inspired by pinball machines using a paper plate and a marble. This engineering activity is great for kids from kindergarten age up through 4th, 5th, and 6th grades!

This one is unique, can be a lot of fun, and is even easier for younger students.

Build a roller coaster for a ping pong ball out of straws, hot glue, and a cardboard box for a base.This STEM challenge for kids is awesome because the materials are so simple and inexpensive!

The track is surprisingly sturdy, and kids will have a blast creating a path for their ball. I would recommend this project for ages 8+, but younger kids will enjoy building it with help.
