Creative Ways to Learn About the Solar System

 I love science and art, so I especially love it when we can find ways to combine the two. Earlier this year we did a unit on the solar system. As we studied each planet we looked at photos and learned about surface features and then made a watercolor painting. It ended up being so much fun, and one of our favorite projects of the year!

Below I share some fun facts and a couple online resources for each planet, and some more fun solar system activity ideas:



Planet Facts

The solar system has 8 official planets. 4 terrestrial or rocky planets, 2 gas giants, and 2 ice giants. 

Mercury- Mercury is the closest planet to the sun. It is a rocky planet covered with impact craters. It is the smallest planet, just slightly bigger than Earth's moon. A day on Mercury is equal to about 59 Earth days. A year on Mercury is about 88 Earth days. That's a pretty short year!

Learn more about Mercury with these resources:

-Planet Overview- Mercury from NASA

-Mercury 101 video from National Geographic

-Crash Course Astronomy- Mercury


Venus- Venus is the second planet from the sun. Despite being further from the sun than Mercury, Venus is the hottest planet. The high amount of carbon dioxide in its thick atmosphere causes heat to get trapped, wrapping the planet in a hot blanket of air. 

A day on Venus is 243 Earth days, the longest of any planet. A year on Venus is 225 Earth days making a year shorter than a day!

Venus is easy to spot in the night sky, as it is the brightest object in the sky other than the moon. 

Learn more about Venus with the following resources:

-All About Venus from NASA

-Venus 101 from National Geographic

-Venus from Crash Course Astronomy


Earth- Earth, our planet, is the third planet from the sun. It is the only planet in our solar system known to have life. The Earth is a terrestrial planet, and it has one natural satellite- the moon.

Learn more about Earth with the following resources:

-Earth 101 video from National Geographic

-All About the Moon Unit Study


Mars- Mars is the 4th planet from the sun. It is a rocky terrestrial planet and has a reddish color due to the high amount of iron in its crust. Mars is named for the Roman god of war. It has two satellites named Phobos and Deimos.

A day on Mars is equal to about 24 hours and 37 minutes Earth time. A year is about 687 Earth days.

Learn more about Mars with the following resources:

-Mars Overview from NASA

-Mars 101 video from National Geographic

-Mars video from Crash Course Astronomy


Jupiter- Jupiter is the 5th planet from the sun and the first of the gas giants. Jupiter is the largest planet in the solar system and is more than twice as massive as all the other planets combined. It was named after the king of the Roman gods.

A day on Jupiter is about 10 Earth hours. A year is about 12 Earth years.

Jupiter has a total of 67 known moons. Its 4 largest moons are known as the Galilean moons and they are large enough to be seen from Earth with binoculars or a fairly low power telescope. They are named Io, Europa, Ganymede, and Callisto.

Activities to Try

Planets of the Solar System Watercolor Activity

Look at pictures of each planet as you work through the solar system. Take notice of the color of its atmosphere and any interesting surface features. Then make a watercolor painting of each planet. You can grab free printable planet templates here.


Make a Solar System Wheel

For this activity you will need:

-A very large cardboard box (thin cardboard is best)

-A piece of cardstock

-Paint (tempera or acrylic)

-Scissors

-A long screw with a bolt and two washers

Start by cutting 8 circles out of cardboard. Make the first circle about 2 and a half inches in diameter, and then make each following circle about 2 inches wider than the previous circle. 

Paint each cardboard circle black and add some white splatters for stars and set them aside to dry.

While the cardboard circles are drying, cut 9 small circles out of the piece of cardstock. These circles should be about an inch in diameter. 

Paint 8 of the small cardstock circles to look like the planets. Paint the remaining one to look like the sun. 

When everything is fully dry, stack the black painted cardboard circles starting with the largest on the bottom working up to the smallest one on top. Using a sharp pencil or a screw driver, poke a hole in the center of each one. Then fasten them together with the screw, washers, and bolt (the bolt should be at the bottom).

Glue the cardstock sun in the center of your wheel- on the head of the screw. Then glue your planets in place- one on the edge of each cardboard circle, starting with Mercury on the smallest circle, working out to Neptune on the largest circle. 

Once the glue is dry you should be able to spin each planet independently around the sun in the center!



Make a Solar System Model

Try making a model of the solar system. You could use a kit like one of these:

-3D Solar System Model Kit

-Solar System String Light Kit from STEAM Powered Kids (my 5 year old did this kit recently and it turned out pretty cool)

Solar System String Line Kit from STEAM Powered Kids

Or you could try making one from scratch. We made one out of paper mache, a coat hanger, some wire, and some paint a few years back.

View Planets in the Night Sky

Head outside after dark to observe the planets in the night sky. Mercury, Venus, Mars, Jupiter, and Saturn are all easily visible with the naked eye. And with just a low powered telescope or a pair of decent binoculars you can see Uranus, Neptune, Saturn's rings, and Jupiter's 4 largest moons. 

For help locating the planets, download the SkyView app.

I don't know about your kids, but mine absolutely love games involving water and getting wet in the summer time. In  this post I share 5 of our favorite water relay races to play with friends. These are perfect for birthday parties, homeschool get togethers, and other group events. Sponge Relay: For this relay you will need: - 2 teams of several kids each -2 large sponges -4 small buckets or containers of some sort Divide your participants into 2 teams and have each team line up single file at a predetermined starting place.  Hand out a sponge to the first participant in each line. Set a bucket of water by each team. Set an empty bucket about 20 ft away from each team.  The two empty buckets should be the same size and should have a "fill line" marked half way up. On a count of 3 (or ready set go) the first participant in each line should dip their sponge in the bucket of water, run to the empty bucket, squeeze the water from their spo

STEM Art: 21 STEAM Project Ideas

My kids love STEM projects and we're always looking for ways to add more art to our homeschool days, so I decided I am going to try to dedicate one morning a week this year to STEM art activities. In this post I share some of the ideas we're planning to try, plus a few favorites we've done in the past. What is STEM Education? STEM education is a blended and often hands on approach to teaching science, technology, engineering, and mathematics, which are some of today's fastest growing industries. STEM education offers students the opportunity to problem solve and work on real world problems and questions. Sometimes the acronym STEAM is used, to include the arts. Adding art to STEM education encourages creative thinking and problem solving skills. It can also help make the other included subjects more appealing to some students.

Learning About The Human Body Part 1: The Skeletal And Muscular Systems

At the end of each school year, I sit down with my daughter to discuss what topics she wants to learn about the next year. One of her science topics she picked to study this year was the human body. Instead of ordering a boxed curriculum set, I decided to put together my own human body unit. In this post I share some of the resources we used for learning about the human skeletal and muscular systems, plus instructions for a couple hands on learning activities. You can find my post about the human respiratory and circulatory systems  here , and my post about the human digestive and nervous systems  here . The Human Skeletal System Our skeletons are the frame of our body. They give us structure, without them our bodies would be limp like noodles. They also provide places for muscles to attach so our bodies can move. Why Does Your Body Need Calcium? Experiment: This is a simple experiment you can do to explore why calcium is important for our bones. You will need: -several clean
