A Shot Under Pressure
Posted on January 29th, 2016 by Mary Lord
Teams of high school students use their understanding of projectile physics and fluid dynamics to calculate the water pressure in squirt guns by measuring the range of the water jets. They create graphs to analyze how the predicted pressure relates to the number of times they pump the water gun before shooting.

In this activity, elementary students in grades 3 to 5 learn about reverse engineering and how to collect and represent data graphically by investigating different balls and their abilities to bounce.
In this activity, teams of students in grades 5 to 7 learn about environmental, civil, and sanitation engineering by designing and building model landfills that hold the most garbage, minimize costs, and prevent trash and contaminated “rainwater” from polluting the nearby “city.” Teams test their landfills, and graph and compare designs for capacity, cost, and performance.
