In this unit, students explore the science phenomena of animal behaviors of parents and offspring that help the offspring survive. This page is a high-level extract of lesson two in which students mimic the beaver’s behavior of building dams to design their own dams that solve the problem of flooding.
In the last unit, students explore how objects can be seen when they are illuminated by a source of light and how light passes through opaque, transparent, and translucent materials differently. In this unit, students apply what they have learned about light and sound to design a solution that can be used to communicate over a distance.
