Visualize STEM

Thermagram handIn this lesson, high school students learn the value of writing and art in science and engineering by designing visual diagrams to communicate the results of thermal conductivity (heat flow) experiments they have conducted to anyone with little background on the subject. The principles of visual design include contrast, alignment, repetition, and proximity, and involve such elements as the use of lines, color, texture, shape, size, value, and space.

A Shot Under Pressure

super soaker water gunTeams 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.

Paper Penny Bridge

stacks of penniesIn this activity, student teams in grades 8 and up learn about the engineering design process and physical forces by building a bridge from a single sheet of paper and up to five paper clips that will span 20 cm and support the weight of 100 pennies. Like real engineers, teams also have limited budgets and must make trade-offs in materials.
