The Sun’s gravity holds this solar system together and, in fact, it’s the reason we even have a solar system. Its pull is so strong that it can even “grab” comets millions of miles away. So the Sun is the most massive thing in the neighborhood. Everything else makes up just 0.1 percent. The Sun has 99.9 percent of all the matter in the solar system. All objects pull other objects toward them, and the more mass (or matter) an object has, the stronger its pull. Why don’t all these planets, moons, and asteroids just stay where they are? The answer is gravity. Comets fall into planets, and asteroids smash into moons. Sometimes these spinning, circling, moving objects crash into one another. Earth orbits the Sun, and so do other planets, their moons, and asteroids. While these objects rotate, they revolve around, or orbit, each other. Other planets and moons spin, too, and even the Sun itself spins. The egg is probably the easiest object for young children to spin because of its shape.You and everything else on Earth are traveling up to 1,000 miles per hour right now! That’s how fast the planet’s surface is spinning, or rotating, at the equator. The egg and game die were the most popular. The children like to see which objects spin the best. This is a fun science center display you can use any time of year. They will catch on quickly because they are so motivated. Show them how to hold the objects upright on the table and give them a quick twist. Mini bottle (a Cracker Barrel syrup bottle)Ĭhallenge children to see if they can make the items spin on a table.I used mostly “found” items as well as some inexpensive toy spinning tops found in the party section of a store. The more variety you can find, the more interesting this center will be. To set up this center, collect a variety of objects that you can spin on a flat surface. Make this paper toy and be mesmerized by the colorful action 15. Your prekinders will be drawn like magnets to the science center! Design colorful mini mazes using large Perler beads 14. Setting up a tray of “things that spin” is an inviting activity young children.
