Science Fair Project Description

Introduce kids to the wonders of space with a sensory bin with bouncy balls as planets, glow-in-the-dark stars and black beans as the expanse of space.


The hypothesis is that a fun sensory bin with planets, stars, the moon and the Sun will give kids a good introduction to the solar system.


The solar system can be a difficult concept for young kids to grasp because they can't physically see it, except for the stars and the Sun. This sensory bin activity provides an opportunity for them to become familiar with the other planets and the vast space in which our planet Earth is located. They can also see where the stars and the Sun fit into this space.

Scientific Terms

space, planets, moon, sun.


You will need colorful bouncy balls, glow-in-the-dark stars, a plastic container or tray and enough black beans to cover the container or tray.


1) Fill the container or tray with the black beans.

2) Put the bouncy balls in, with one that represents Earth, a smaller one that represents the moon and the largest one with a yellow, orange or red color that represents the Sun. Put a few more bouncy balls in to represent the other planets.

3) Put the glow-in-the-dark stars in.

4) Let the kids play with the sensory bin while explaining the concept of planets, the moon, the Sun, the stars, and the concept of a very big big area of space. You don't need to introduce the names of the other planets yet. You could explain that the planets orbit around the Sun.

5) At the end of the time, you can turn off the lights or bring the container into a dark room to show the kids the glowing stars.


This is a fun activity for young kids to explore the solar system.

Also consider

Add a space shuttle, rocket or astronaut toy figure to introduce space exploration. Use wild rice (black color) instead of black beans.
