G.A.T.E. Students at Fourth District Elementary Participate in STEM Activity
Ms. Gina Eason’s G.A.T.E. students at Fourth District Elementary participated in a STEM activity to test their hypotheses about the effects of friction and weight on the speed of the bobsleds they designed for the project. Lydia stated, “We got the idea from the NBC website Science and Technology in the Winter Olympics to build bobsleds to learn new science terms.” “During our experimentation we observed that weight increases the speed the majority of the time,” said Mary Evelyn. Andon explained, “However, we discovered that some heavier bobsleds that are wider, touch the sides causing friction which therefore decreases speed.” After many testing opportunities we know for sure that gravity is the force acting on the sleds causing them to move from potential energy behind the gate to kinetic energy down the track. Colby added, “After several time trials our group realized that an increase in the incline of the track increases the speed because there is more gravitational pull.” “While doing this project we recognized just how fun and exciting science and technology can be!” yelled Hank.
