How Do You Make A Simple Machine For 2Nd Grade?
Pulleys, levers, wedges and inclined planes are all examples of simple machines that can be used to reduce work. Building a simple machine is a great way for a 2nd grade class to learn about how these machines work and how they can be useful. The following steps describe how to build a simple pulley and observe how it can lift more weight with less force. Step 1 Provide enough materials for students to build their own pulley systems in pairs or small groups. Before the lesson, attach a pulley to one end of the boards, and a hook to the other side. The pulley and hook should be next to each other on the same end of the board. Step 2 Clamp the board to the edge of a desk with the clamp or vise. The pulley and hook should extend off the edge of the desk, facing down. Step 3 Fill the small bucket with stones and tie the rope to the small bucket’s handle. Put the small bucket on the floor and run the rope over the top of the board. Tie the large bucket to the other end of the rope. The larg
