Solar System Project

If your students is learning about our solar system in astronomy, they are going to learn the planet names and the planet order. Most lessons have children make a¬†solar asystem planets project to reinforce that knowledge. This silly and FUN¬†solar system project combines¬† easy solar system projects and a¬†space science experiment. After teachign planets to preschoolers, you will dig in and make solar system model for kids. Once you have made all the Mars, Earth Venus, Mercury, Venus, Jupiter, Saturn, Uranus, Venus, and the sun, it’s time to turn it into a baking soda and vinegar experiment. Children will be delighted by this surprise twist to the project where they will cause the planets to fizz, bubble, and errupt. This baking soda and vinegar reaction will delight students of all ages! Try this¬† planet activities for preschoolers, toddlers, kindergartners, grade 1, grade 2, grade 3, grade 4, grade 5, and grade 6 students.

baking soda and vinegar experiment

Solar System Project for Kids

To try this fun homemade school project solar system model all you need are a few simple materials:

  • baking soda (the amount varies by the size of your planets, but you will need several boxes)
  • water
  • dish soap
  • vinegar
  • food coloring
  • toothpicks and orange pipe cleaner (optional) to make Saturn’s ring
  • FREE Printable planet book as a visual aid

Model of solar system for school project

Space science experiments

Start out by mixing baking soda, water, and dish soap until you get a consistency that will hold a ball form without being too runny.

Now form planets on a dish or pan with a lip. You can have the planets in a line or going around the sun in an orbit.

How to scale you get your planets is up to you depending on the age of your child.

planet project for kids

You can add in the food coloring as you shape them or at the end.  We tried to make ours look like the images of the planets from NASA.

NOTE: If you add the food coloring at the end like you are painting the planet it does not saturate the inside of the ball and thus will not make as colorful of a melting planet at the end. On the plus side, it uses less food dye. We tried it both ways.

The order of the planets in the solar system starting with the sun on the left and working outward is the Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune.

Solar System Planets Project

Don’t the planets look so pretty all in a line. The colors and sizes came out super cute!

We added an orange pipe cleaner that we attached with a toothpick around saturn to make it look a little more authentic.

At this point our project looked just like a typical solar system model you would make for a science fair. It is hard to tell that they are made of a base – baking soda. They could just as easily have been made of playdough, paper mache, craft foam, etc.

But now is when the fun begins! Have your child use a pipette, eye dropper, or carefully pour a small amount of vinegar on a planet.

Solar System Planets Project

The key, in my opinion, is to pour just a little bit of vinegar to get the bubbly, foamy reaction SLOWLY.

Remember to have your planets on a surface with a lip so the melted planet doesn’t run everywhere!

Isn’t that BEAUTIFUL!

Planet learning for kids

Baking Soda and Vinegar Experiment

The baking soda and vinegar react causing carbon dioxide gasto push out which is why it looks like it swells. The dish soap we added starts to bubble which is why it looks foamy. As the baking soda changes form the planet will look like it is melting.

Baking Soda and Vinegar Reaction

Continue adding vinegar at the rate you like. After a while the kids had seen the small fizz enough and they were ready for a more dramatic melting of the planets. To really get the vinegar and baking soda reaction going, simply pour more vinegar. We neded up with a beautiful combination of converging colors and melting planets. Continue adding vinegar until the planets have dissolved.

  • Thank you for all your resources.
    For the Fizzy Planets activity, do you have measurements. I could not see any listed…so how much Baking soda, water and dish detergent are best to start with to make your planets.
    THANK YOU!
    Julia AKA Nonna to three grandkids

    • The activity is so forgiving, no exact measurements needed! I promise =) Make them as big or small as you want. Just a squirt of dish soap and as much water as you need to make your baking soda stick together.
