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 harder or easier. Then they learned about the six simple machines by participating in a series of experiments and activities.
The first graders learned about levers and balanced a lever on a fulcrum. They had a bubble race and learned how a wheel and axle makes work easier. They also used a pulley to avoid lifting objects, and had an egg drop challenge. The first graders learned that using an inclined plane makes it easier and safer to move a load. They also made a paper helicopter and learned how a screw works. Lastly, the class made funny faces with oranges and popsicle sticks and learned that the shape of a wedge was easier to use.
The first graders had a great time learning about simple machines through these hands-on, fun experiments. To make the lesson even more fun, each student created and built their own inventions.
First grade has so much creativity and these inventions rock!
