How Fish Maintain Neutral Buoyancy
In this buoyancy activity, 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.

Buoyancy Bulls-Eye
Why does a seastar sink, but a jellyfish float? Through a fun investigation, learners examine the concept of buoyancy using simple household items. The challenge: create neutral buoyancy for an action figure in water. With ample teacher...

Exploring Buoyancy
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...

Come On Down!
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...

The NBL Pool
That is a lot of water. Class groups explore the size of the NASA's Neutral Buoyancy Pool and calculate the volume of water needed to fill it. They then compare that volume to the amount of water needed to fill a pool the size of a...

Newton’s Cool in the Pool
Pupils work together to investigate the cooling of NASA’s Neutral Buoyancy Laboratory. Using data collected as the pool cooled, groups determine the values needed in Newton's Law of Cooling equation to model the situation. They...

Cartesian Diver
Amaze your scholars with an activity that uses a Cartesian diver to demonstrate Pascal's Law, Archimedes' Principle, and the Ideal Gas Law. Groups then repeat the process and make their own diver move up and down in a bottle.

Floating Fishes: Boat Sinking Lab
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,...

Pilot a Balloon
Balloons will go where you want them to. Young pilots first add paper clips to a balloon to make it neutrally buoyant. They then use cardboard to steer the balloon in different directions, taking air pressure into account.

Design a Submarine
Don't just sink the boat. Using a closed container as a submarine, pupils experiment to see what to add to the container to make it float, sink to the bottom, and hover in the middle. After finding one option, learners see if they can...

Technology of the Deep: Experiments with Buoyant Forces
Students conduct a series of experiments to study the effects of temperature and salinity on the buoyancy of an object in water. They devise ways to make floating and sinking objects neutrally buoyant.
