A simple machine is an instrument that changes the direction of the force. You can easily make simple machines for your science project. Here is the tutorial to guide you on the steps to make a simple machine. Let’s learn how to make two types of simple machines at home.
Before making anything, it’s pretty much better to gather all the required stuff in one place to avoid any fuss.
Steps To Make A First Class Lever (Seesaw)
Step 1: To make a first-class lever, take a piece of cardboard of 20×3 cm.
Step 2: Take a stick and two cardboard pieces, as shown below.
Step 3: Take a cardboard strip of dimension 20 x 3 and cut it in the shape of an ice cream stick.

Step 6: At the corners of the strip, put a different color of paper.
Step 7: Later, take a straw and cut it short, and stick it to the seesaw.
Step 8: Now, stick a toothpick under the strip and insert it into the two cardboard wheels.
Steps To Make A Pulley
Step 1: Take cardboard of measurement 17×9 cm.
Step 2: Take another cardboard of measurement 19×4 cm.
Step 3: Wrap the cardboards with colored paper.
Step 4: Make two wheels from the cardboard of diameter 3cm.
Step 5: Glue it with the help of another circular cardboard.
