Young scholars have seen that solids, which are more dense than a liquid, that sinks in that liquid and solids, which are less dense than a liquid, that floats on that liquid. They use a metal boat to float in water. Pupils comprehend...

Combine science and literature with this lesson on buoyancy. Read There's an Ant in Anthony by Bernard Most to examine words containing the letters a, n, and t. Then introduce your class to the word "buoyant." Demonstrate how an egg...

Students explore physical science by conducting an in-class experiment. In this density lesson, students define vocabulary terms dealing with physics and discuss their knowledge of density. Students conduct several "sink or float"...

Begin with an introduction to famous deep-sea submersibles. Learners work in groups to gather information on different vessels and then share with the class. Each group then uses water displacement to help calculate the density of...

What do we do when a dive is too dangerous for humans to accomplish? Send in the robots! Middle school scientists get acquainted with several different models of submersible robots in the second lesson of six from NOAA. Lab groups then...

Students discuss possible reasons for the Titanic sinking. They are split into small groups to research a historical figure involved in the sinking of the Titanic. They formulate a way to prove their characters guilt or innocence....

Fourth graders explore and experiment with objects that float to see if they float differently in salt water or fresh water. After the experiment, they write a paragraph in their science journal explaining how fresh water and ocean water...

Students explore an estuarine system to gather data on density driven currents. This type of current is contrasted with temperature and wind driven currents.
