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.

Junior high schoolers explore possible theories for the cause of the Hunley submarine sinking. Through hands on activities, they investigate how to create a waterproof seal. Afterwards, they discuss how seals work and various...

Teach your environmental studies, life science, or engineering class how an internal combustion engine works using the first few slides of the accompanying presentation. Then, focus in on the resulting carbon emissions. Finally, take a...

Students explore the ocean depths. In this scenario based lesson, students pretend they are on a submarine in an unknown part of the ocean. By using clues the class discusses and determines where they are in the ocean. They follow up...

Students 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...

Learners 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, through hands on games and activities, discover how bats live and how bats benefit ecosystems. They play a game designed to show them how echolocation works and another to show how mother bats locate their young through their...

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

Students 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.

Students study an article and answer questions.  In this exploring robots lesson students read an article on military robots and answer questions. 

Explore the streamlined shapes of submarines and design an effective hull shape. Observe how streamlining affects a vehicle as it is pulled through a water-filled trough.
