Solar System Inner Planets Activity for Kids

We are continuing on in our solar system unit. We’ve talked about the sun and now we are ready to start learning about the Solar System’s inner planets activity. We read books, did some hands-on inner planets activities, and of course added in some inner planets worksheets. : Mercury for kids, Venus for kids, Earth for kids, and Mars for kids. This is a really fun, hands on unit includes both solar system science experiments and solar system for kids printables to help kids learn while having fun.

Mercury for Kids

We made a model of mercury by mixing 1 cup of flour, 1/4 cup salt, 1 teas oil, and 1/4 cup water. After we’d shaped it we hit the planet with rocks of different sizes to make the craters Mercury is known for.

Venus for Kids

Igneous rocks for kids

To help the kids understand that Venus was so hot that rocks melted we set up this simple science experiment. We made a mound by overturning a custard dish and covering it and the surrounding area with flour. I showed them a 1/4 stick of butter was solid like rocks. I melted it in the microwave just like the heat melts rocks on Venus. Then we poured it over the center of the overturned custard dish so the kids would see it form streams. When it cooled down the butter turned back hard, just like the rocks on Venus.

We read several books  on earth discussing how the earth is the perfect home, the layers of the earth, how the atmosphere protects us (keeping us warm and burning up meteors before they hit the earth), how our tilt gives us seasons, and more.

For hands on activities consider making a playdough earth (showing the layers) or make a compass (because of our powerful magnetic field a compass always points north)

Mars for Kids

This terrestrial planet has mountains, valleys, and volcanoes including a volcano called Olympus Mons the largest volcano in our whole solar system.

To make our Olympus Mons we put red construction paper on a baking sheet. We put an empty 2L bottle in the center.

We wadded up paper around the 2L bottle to make the volcano. Then we covered the entire surface with our favorite playdough recipe tinted brown. The volcano looked amazing!

Now for the eruption! We put 6 teas baking soda in the bottle. In a separate measuring cup put 2 cups vinegar, red food coloring, and a squirt of dish detergent. When you are ready for the eruption pour the vinegar mixture into the bottle and stand back – it is going to erupt!

Plus for every planet we studied the kids took notes on things they learned that were interesting using these free solar system worksheets for kids.
