Third Grade Forces of Motion

Third graders have been introduced to a new design problem that focuses around how to rescue a trapped tiger at the zoo! We began learning about different forces of motion including friction and gravity. Next students explored balanced and unbalanced forces and were introduced to simple machines. Students were so excited to start using the VEX kits! They’ve worked in teams to build an inclined plane, lever, and pulley with VEX pieces. Next we’ll be looking at compound machines and designing a way to combine the simple machines into a compound machine. Students are beginning to think about how these machines could help them rescue the tiger!
