Through the activities, children will learn what scientists have discovered about our Solar System and feel both a sense of awe and connection to our world each time they look at the sky.  \nAll of these adventures call on students to predict what will happen, test their theories, then share their results. They’ll be introduced to astronomy vocabulary, make items they can take home to expand their adventures and come home armed with enough knowledge about the night sky to share with their family.  \nThe lessons in this unit were adapted from various NASA resources and from“Astronomy – It’s Out of this World” 4-H Leader/Member Guide by Brian Rice.

Scale model of our solar system  \nMain Idea  \nScale models make it easier to comprehend the vast sizes and distances in our solar system.  \nMotivator  \nDid you know that Mercury, the closest planet to the Sun, is still 36 million miles away from the Sun? Earth is 93 million miles from the Sun? Don’t know how far 93 million miles is? Let’s find out by making a model of our solar system.  \nPre-Activity Questions  \nBefore you start the activity, ask the students:  \n􀂉 How many stars are in our solar system? (One, our Sun)  \n􀂉 How many planets are in our solar system? Can you name them in order? (Assign students a planet name and line up in order of the planets.)  \n􀂉 Do you know any mnemonic (memory) phrases to help remember the planets?  \n􀂉 Do you know the two main types or groupings of planets?  \n􀂉 How is Pluto now classified?  \n(See background resources for answers)  \n\n| Activity\u003Cbr>􀂉 Basketball\u003Cbr>􀂉 Grain of sand\u003Cbr>􀂉 Two peas of different sizes\u003Cbr>􀂉 BB\u003Cbr>􀂉 Golf ball\u003Cbr>􀂉 Ping pong ball\u003Cbr>􀂉 Two gum balls\u003Cbr>􀂉 Meter stick\u003Cbr>􀂉 A half-mile field, football field or at least 15 feet of clear space\u003Cbr>􀂉 Cardboard and sturdy bamboo skewers (optional, for making signs) | You could also use other\u003Cbr>objects of similar size and scale to eachother. |\n| --- | --- |\n| 1. This activity demonstrates the relative placement (order from the Sun) of the planets and relative size difference between them.\u003Cbr>2.
