Elephant Toothpaste

Last week we pivoted in science from a focus through a series of lessons on how engineers solve problems to deeper work on the nature of science and how scientists think and work. Mrs. Swanson took the group through a demonstration that involved catalyzing the breakdown of hydrogen peroxide. The result of the very exciting demonstration was that a huge swath of thick foam poured out of the graduated cylinder, and the timely addition of food coloring made the foam look like large toothpaste, or “Elephant Toothpaste."

Engineering Solutions: Keeping Water at Bay

Engaging in the practices of engineering helps kids understand the work of engineers, as well as the links between engineering and science.

As problems are identified and solutions are needed, often times the solution is developed through the engineering design process. Engineers, like scientists, utilize a series of practices as they design solutions to solve meaningful problems…
