Fizzing Planets Solar System Project for Kids

Are you looking for an easy solar system projects to try? This fizzy planets experiment is quick and easy, with a fun twist that kids will love. In this fizzing planets children will will create each of the planets – which is great for learning planet names, shapes, sizes, and position from the sun. Then kids will create a chemical reaction with a fun experimento del sistema solar that will make their planets fizz, foam and melt. This space experiments for kids is perfect for kids of all ages from toddler, preschool, pre-k, kindergarten, first grade, 2nd grade, 3rd grade, 4th grade, 5th grade, and 6th graders too.

fizzy planets

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.

We have lots more science for kids and solar system activities to choose from! Plus don’t miss our solar system for kids pdf booklet, free solar system coloring pages, free solar system worksheets, and pipe cleaner constellations.

fizzy planets experiment

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

fizzing planets

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.

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.

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.

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!

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.

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.

space experiments for primary school

This is such a fun, simple solar system project for kids of all ages to explore both the planets in our solar system, as well as a fun chemical reation with a simple chemisty experiment for kids! Next time I would add big chunky glitter stars around the planets for effect!
