Saltwater: Nifty Aqueous Colorful Layers

For Teachers 6th - 8th
A classic investigation on the density of liquids is explained for you in this lesson plan. Te begin, you prepare water samples of different salinities and then add different food coloring to keep them separated and easily identified....
Lesson Planet

Come On Down!

For Teachers 6th - 8th
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...
Lesson Planet

Build a Model Submarine

For Teachers 4th - 8th
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...
Lesson Planet

Construct a Buoyant Scuba Diver

For Teachers 6th - 8th
Groups of young oceanographers get to use action figures to experiment with the property of buoyancy! This memorable lesson plan provides detailed background information, a link to the laboratory worksheet, and thorough instruction...
Lesson Planet

Exploring Buoyancy

For Teachers 4th - 8th
Students use materials found at a resource table to design simple devices that will house instruments to take water samples from a tub of water. They design 3 instruments, each varying in density so that one will float, one will hover...
Lesson Planet

Sink or Float?

For Teachers K - 2nd
Have your class explore density and buoyancy using this resource. Learners read the book Who Sank the Boat, and use several items, such as rubber balls, bottle caps, wood, and other household items to conduct an experiment. Using a tub...

Natalie Morales: Float

For Teachers Pre-K - K
Natalie Morales performs a simple experiment to show what the word float means by placing a pumpkin in water. This video could be used as an introduction to a science experiment on buoyancy. It would be fun to have your class experiment...
Lesson Planet

Float a Boat

For Teachers 3rd - 8th
Students design and build a floating vessel with its own propulsion system that will carry cargo across a wading pool.
Lesson Planet

The Stone Boat Mystery

For Teachers 6th - 12th
Students design and execute a lab through which they study the distinctions between density, buoyancy, and volume.
Lesson Planet

Bubble and Boyle

For Teachers 6th - 8th
Middle-schoolers still enjoy playing with bubbles! In this series of eight laboratory activities, science learners explore convex and concave surfaces, angles, gas laws, buoyancy, density and more! 
Lesson Planet

Bubble Suspension

For Teachers 5th - 9th
Create a cushion of carbon dioxide gas to float some soap bubbles on. Many concepts can be demonstrated through this activity: Carbon dioxide gas is more dense than air Bubbles are semipermeable, allowing only carbon dioxide to diffuse...
Lesson Planet

Floating Fishes: Boat Sinking Lab

For Teachers 4th - 8th
Cut milk cartons in half to make boats and let investigators attempt to sink them. They add dividing walls and observe what happens if marbles are put into only one of the newly formed compartments. Vocabulary is provided: buoyant force,...
Lesson Planet

Physical Science- Sink or Float?

For Teachers K - 2nd
Learners investigate which objects sink and which ones float. Learners engage in an experiment, make predictions, and record results on a graphic organizer. This is a comprehensive and easy to follow resource.
Lesson Planet

Sink or Float

For Teachers K - 2nd
Using a variety of objects, learners conduct buoyancy experiments. They make predictions on which object will sink or float and test their predictions. They use a graphic organizer to record their findings.
Lesson Planet

Thermo and Fluid Dynamics of a Homemade "Lava Lamp"

For Teachers 9th - 12th
Learners construct their own lava lamp using simple substances. For this physics lesson, students explain how difference in density causes convection. They solve for forces and buoyancy using mathematical equations.
Lesson Planet

How Fish Maintain Neutral Buoyancy

For Students 7th - 10th
In this buoyancy worksheet, students read about neutral buoyancy and that the downward force of gravity is equal and opposite to the upward force of water. They answer four critical thinking questions about buoyancy.
Lesson Planet

Salinity

For Teachers 4th - 12th
Learners take a provided ocean Trivia Quiz in order to start a discussion of the ocean. They then perform an experiment on how the amount of salt in the ocean affects it and varies from ocean to ocean.
