Biocomplexity Lab Activity: Density and Buoyancy of
Students investigate how the density of water changes the buoyancy of
water. Students create a hypothesis about what will happen when placing the
egg into the water.Students can research online different bodies of water (The Red Sea, The...

The Weight of Water
Learners examine how salt water is more dense than fresh water. They discuss how manatees need to float and sink, conduct a sink or float experiment, and conduct an experiment with eggs and salt and fresh water.

Bathtub Physics - Density, Buoyancy and Flotation
High schoolers study Archimedes' Principle, flotation and the reaction of buoyant forces and explain the relationship between density and flotation.

Habitats and Adaptations
Students research and describe the habitat and adaptations of a reef animal. After the student is assigned a habitat, they design and draw a cresture adapted to eat each food and to live in each habitat.

Learning Lesson: Salt 'n Lighter
Learners participate in a demonstration showing that as salinity increases density increases as well. They also examine the different densities of air. They discuss the amount of water displaced by large ships.

Man Floating in Dead Sea
This site takes an interesting look at the Dead Sea. It provides answers to questions such as: Why is it called the Dead Sea? and Why is the Dead Sea so salty?
