Learners form lab groups and work together to construct a submarine out of a soda bottle. Next, they observe its action in a tub of water as the inner pressure is changed. It is an engaging experiment. However, links to outside resources...

High schoolers construct their own submarine following a certain procedure. In this physics lesson, students calculate the density of objects using a mathematical formula. They explain why some object floats in water while some do not.

Young scholars discover how engineers use sound energy. They participate in hands-on activities in which they discover how we know sound exists. They identify different pitches and frequencies as well.

Students compare and contrast the properties of salt water in the oceans/seas and freshwater elsewhere on the planet. They also analyze mixing caused by currents in the ocean, including the effects of warm and cold water as well as with...

Students study echolocation and understand how dolphins use it to locate prey, escape predators, and navigate their environment. They view a video, "In the Wild-Dolphins with Robin Williams" and see first hand how dolphins communicate. ...

Students explain how electricity is transferred from source to load without actual wires connecting the two. In this physics lesson, students explore how wireless electricity was discovered. They cite practical applications of this...

Young scholars work together to discover the concept of echolocation. They examine dolphins and their behaviors. They discuss how humans could use this information to help them in their everyday lives as well.
