Students perform experiments to see if items will sink or float. In this sink or float lesson, students work in groups to make predictions, and record the results. After the experiments are complete students make a book of the results.

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...

Students 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 that...

Students inspect nutrition by conducting a science experiment in class. In this vegetable identification lesson, students examine a group of different veggies and predict whether they will sink or float in a tub of water. Students check...

Learners design, build, and test the specifications (water displacement and load line) for a model boat. The lesson focuses especially on integrating design principles with inquiry-based experimental skills.

Sixth graders develop an understanding of floating, sinking, density, and buoyancy and apply it to the design of testing of ships.

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"...

First graders discuss why some things sink and some float after dropping a variety of items into water.

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 physics by conducting a class experiment. In this density lesson, students examine a list of items and discuss whether they will sink or float and then determine their density. Students examine the objects over five days...

Students analyze the relationship between density, buoyancy, and salinity. In this chemical properties lesson, students read a background activity for the lesson and experiments to the topics. Students discuss the questions and complete...

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...

First graders write about vehicles that float using the interactive writing procedure.

Students investigate buoyancy by participating in a lab experiment. In this density lesson, students utilize vinegar and alcohol in beakers and attempt to float different items in them. Students analyze which items float and do not while...

Pupils perform experiments to examine if debris float, or blow in the wind. The effects of these characteristics on the marine debris are then discussed. They determine how a material can influence what becomes marine debris.

Students perform simple and fun experiments to use the scientific method, take careful notes, and write a lab report. They first make and test a hypothesis about how many drops of water they can fit on the face of a penny and then test...

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....

First graders write about vehicles that float.

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 will perform experiments to examine if debris will float, or blow in the wind. They discuss the effects of these characteristics on marine debris.

Students formulate a hypothesis using critical thinking skills. They use an orange to examine the displacement of water as the orange sinks or floats.

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 observe how different water densities control the depth at which different water masses occur. They explain one fact that they comprehend about salt water. Students comprehend that temperature and salinity affect the density...

Students use density to identify what metal a gold colored weight is made of. They use a spreadsheet to graph the experimental density of common metals and compare the know densities to their calculated density of the known metal.
