In December, the first graders learned about simple machines. The class discussed what work is (the transfer of energy from one object to another in order to make the second object move in a certain direction) and what makes work easier and harder. Then they learned about the six simple machines by participating in a series of hands-on activities.
The first graders learned about levers and balanced a lever on a fulcrum. They had an egg drop challenge and learned that an incline plane made it easier and safer to move a load. They made a paper helicopter and learned how a screw works. The class made funny faces with apples and sticks, and discovered that the sticks in the shape of a wedge made it easier to split the apple skin apart. They had a bubble race and learned how a wheel and axle makes work easier. Lastly, the class completed a “going up” activity, where they used a string as a pulley so they didn’t have to lift the object with their hands.
The first graders had a great time learning about simple machines through these hands-on, fun experiments. To take their learning a step further, each student created and built their own invention using their knowledge of simple machines. The inventions will be on display in the 1st grade classroom on Thursday, January 18th at 8:40 during their Invention Show. All Saklan community members are invited to stop by and check out the creative inventions the first graders designed!
