Ring around the Rosie
Students learn the concept of angular momentum and its correlation to mass, velocity and radius. They experiment with rotation and an object's mass distribution. In an associated literacy activity, students use basic methods of comparative mythology to consider why spinning and weaving are common motifs in creation myths and folktales.
Kinetic and Potential Energy of Motion
In this lesson, students are introduced to both potential energy and kinetic energy as forms of mechanical energy. A hands-on activity demonstrates how potential energy can change into kinetic energy by swinging a pendulum, illustrating the concept of conservation of energy. Students calculate the potential energy of the pendulum and predict how fast it will travel knowing that the potential energy will convert into kinetic energy. They verify their predictions by measuring the speed of the pend
All Caught Up: Bycatching and Design
Bycatch, the unintended capture of animals in commercial fishing gear, is one of the hottest topics in marine conservation today. About 25% of the entire global catch is by-catch This surprisingly high level of by-catch is responsible for the decline of hundreds of thousands of dolphins, whales, porpoises, seabirds and sea turtles each year. Through this curricular unit, students will analyze the significance of by-catch in the global ecosystem and propose solutions to help reduce by-catch Stude
In this activity, students will learn the meaning of preservation and conservation and identify themselves and others as preservationists or conservationists in relation to specific environmental issues. They will understand how an environmental point of view affects the approach to an engineering problem.
