The 8th grade class began their science explorations with STEM challenges of Olympic proportions! The students were given 5 different challenges, Regatta, Dominoes, Aerodynamics, Cartesian Divers, and Slow Roller. After a brief introduction to each challenge the students, working in groups, chose three of the five challenges in which to compete.
The students then researched concepts associated with their challenge, discussed and formulated a plan of action and tested their hypothesis. On the day of their challenge the students had 15 minutes in which to create their final hypothesis based on their observations and results from the practices.
Regatta: Students researched buoyancy and created a boat from wax paper, aluminum foil, or copier paper. Once the students had their construction floating they would had gram cubes until the boat began to take on water. The winning boat held 1305 grams!
Dominoes: Students researcher force and inertia. They then designed how they would set up 100 dominoes to knock down with a single push. Each branch added an additional 10 pts. Each 110 degree curve added another 10 pts and any dominoes that fell up or down an incline would gain a two pt. bonus. Highest competitor was 295 dominoes!
Aerodynamics: Students researched Bernoulli’s principle in terms of flight and the force of air. Students designed a paper airplane that would fly as far as it could while remaining in a 90cm width. The longest flight went over 10 meters!
Cartesian Divers: Students researched Pascal’s principle. Placing three divers into a 2 liter plastic bottle filled with water. Students had to manipulate the density and buoyancy of the divers to make them descend on a specific order and rate. Very challenging but all teams were successful!
Slow Roller: Students researched force, inertia and friction. Using a variety of objects, such as, rulers, wooden dowels, and yarn, students designed a course that with a single push keep a marble rolling as long as possible without going off a large piece of construction paper. First and second were divided by a mere .01 second!
Each team earned 5pts for a first place finish, 3pts for a second place finish and 2pts for a third place finish. After all of the challenges were completed the totals were tabulated and the overall Science Olympic Winners for the 2018-2019 school year are:
Trevel A.; Alexis G.; Brooke A.; and Karrion W.
Fidel R.; Jalen D.; Chloe N.; and Brenden D.
Maeve Mc.; Eric R.; Felix Z.; and Jalen J.
