A machine is any tool that makes work easier. Now when I say work, I don’t mean jobs or chores. I’m talking about what scientists call work: making something move. There are six kinds of simple machines, but each can be used in lots of different ways. What makes them simple? Easy, they have just a few or no moving parts. ramp A ramp doesn’t move, but it helps you move things. Roxy is too heavy for me to lift straight up from the floor. But I can push her up a ramp onto the table. A ramp doesn’t have to be straight. It can turn around and around, like the path up a mountain. screw A screw is a pole with a kind of ramp winding around it. But…

One day when Jakey went outside to play, he found a possum in the window well. “Hello, possum,” Jakey said. “You look stuck. How did you get down there, anyhow?” The possum hissed at Jakey. “Whoa, possum,” said Jakey. He backed away. This possum didn’t look cozy and friendly like the possums in his picture books.

You need: • ruler (the lever)• marker (the fulcrum)• can or block (the load)• rubber bands (to attach the load) The fulcrum is the place the lever sits and pivots. It doesn’t move. You supply the effort at the place you push or pull the lever. The load is the thing that gets moved. 1 In a first-class lever, the fulcrum is always between the effort and the load. When you push the empty end of the ruler down, you supply the effort, and the…

Fold the bottom up along the orange dotted line and put a paper clip on it. 4.For each of the three remaining rectangles, repeat steps 1, 2, and 3, then cut along the solid purple line and fold along the green dotted line so one wing points toward you and the other away from you. 5.Lift the toys high, then let them drop. When you drop the yellow toy, it comes crashing down. When you drop the other toys, they turn around and around like a screw. The spinning toys take longer to reach the ground, but they drop with less force…
