Since February, the 8th graders have been studying physics in science class. They have been learning about the forces of gravity, air resistance, and friction on our planet. The students have also been working on putting Newton’s three Laws of Motion into real life scenarios.
To learn about these forces, the eighth graders have been taking part in different hands-on labs to help exhibit how these forces act on objects on our planet. Students first studied friction by measuring the force needed to move different blocks and bricks along different surface textures. These textures included a smooth countertop, markers that roll and sandpaper. Using a spring scale students could measure the force needed to move the objects and the amount of friction the textures were producing.
To see gravity and air resistance, students created different sized parachutes in class and dropped them from the ceiling of the science lab. Students could then see the pull of gravity on the parachutes and how air resistance could be used to slow that force down. Next, students worked on designing, creating, and shooting off rockets to try to see how to defy both air resistance and gravity.
