Sizing Up The Solar System

Pocket Solar System
Make a miniature model of Earth's neighborhood. Our solar system is made up of eight planets and many other objects orbiting the sun. In this activity you will take a one meter strip of paper and follow instructions to approximate the distance of celestial bodies. Instead of using stickers, try drawing a picture of the planet on the line you measured for it. Add in other objects we know of in space like the Jupiter probe Juno or a Mars rover. Download the activity guides and access training videos on the NISEnet website.

Solar System on a String
Another fun way to visualize the distances between the planets of the solar system. In this version you will take a 7ft piece of string, or we like to use flagging tape, and attach a picture of the sun to one end. Then follow the guidelines of where the rest of the planets would be in relation to the sun and staple their labels into place. Stretch it out from the ceiling or across the floor and see how tall you are compared to the planets distance at this scale! Hang it on the wall and use it as a road map to the planets as you dive deeper into space learning! Download an activity guide.

Model the Sun/Earth System
Measure out a scale model of the actual distances of planets in the solar system. This model will be at a 2,000,000,000/1 scale. Hypothesize the distance, calculate the distance, then go outside and measure out the distances between the inner planets. Have one person stand where each planet would be. If it is dark where you are, try bringing five flashlights- one for each planet and the sun. This can also be extended into a factoring lesson. Download the lesson plan and worksheets here, as well as a summary for a table station. This lesson comes from the Geophysical Institute's Cultural Connections Middle School Kit.

Big Earth/Small Moon
We can see a solar eclipse here on Earth because the Sun and Moon appear to be the same size in the sky. Explore how you can trick your eyes with size and distance. Discover that the further away an object is, the smaller it appears. Use any two round objects that are different sizes: a beach ball and tennis ball? a basket ball and golf ball? two different size circles cut out of paper? Download the activity guides and access training videos on the NISEnet website. This activity is appropriate for all audiences.
