How Can We Prevent the Corrosion Crisis?
Contemplate the causes of corrosion. An interesting activity has learners first conduct an experiment where they place nails in different types of water. Based on the results, they consider how corrosion occurs and how engineers need to...
Teach Engineering
Boxed In and Wrapped Up
If cubes have the smallest surface area, why aren't there more cube-shaped packages? Scholars take a box in the shape of a rectangular prism, cut it up, and make new boxes in the shape of cubes with the same volume. They then brainstorm...
Teach Engineering
Stay in Shape
Using their knowledge of right triangles, pupils find out how far a ship is from a light house. Class members determine how far around the world a ship would be sailing at a constant speed.
Teach Engineering
May the Force Be With You: Lift
Get the class up and going with a activity that discusses how airplane wings provide lift. Pupils use their knowledge of Bernoulli's Principle to develop an explanation of how it creates lift on airplane wings.
Teach Engineering
Glowing Flowers
What a bright idea! Young scientists conduct an experiment on flowers to finish the last of a six-lesson unit on Cells. Putting the stems into dye-injected water and leaving it overnight results in flowers that glow. This is to simulate...
