Properties of Balls
Enhance your states of matter lessons with a hands-on science investigation that compares six different balls' color, texture, size, weight, ability to bounce, and buoyancy.
Discovery Education
Future Fleet
Turn your pupils into engineers who are able to use scientific principals to design a ship. This long-term project expects pupils to understand concepts of density, buoyancy, displacement, and metacenter, and apply them to constructing a...

Design and Test an Air Lift Siphon
Build an air lift siphon using your mad physics skills! Learners first investigate the importance of circulating water in aquaponics systems. They then use density to their advantage as they engineer an air lift siphon
PBS
Paddle Power
Potentially get all the way across the water. The fourth of five design challenges asks pupils to develop a plan for a paddle-powered boat that will store its energy. Given a limited number of supplies, the class members design, build,...

Buoyancy-Why Things Float
In this buoyancy worksheet, students read about the principles behind objects floating including density, buoyancy and Archimedes' Principle. Students complete a buoyancy lab where they use a balloon and water and a film canister and...
Curated OER
Buoyancy
In this buoyancy worksheet, students read about why objects float or sink. Students apply the Archimedes' Principle in a buoyancy lab. Students complete 1 graphic organizer.
Curated OER
Cold Hard Facts...What Inquiring Minds Will Know
Learners work with "ice" in order to gain a practical application of math concepts that evolve into an inquiry-based study. They determine if the dimensions of the ice make a difference in the way the ice floats in the water.
Curated OER
The Weight of Water
Students 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.
Exploratorium
Bubble Suspension
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...

Life Vest Challenge
After reading about the history and science of personal floatation devices, patents, and intellectual property, engineering teams design a life vest for a can of soup. To evaluate which groups considered the need for waterproofing, hold...
Curated OER
Physical Science- Sink or Float?
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.

Can You Canoe?
A neat handout immerses learners in the history of canoe making. After reading, small groups of mini engineers work to craft a canoe that will not be immersed! This is an ideal exercise in engineering design for your STEM curriculum or...
CK-12 Foundation
Going Fishing
Why do some things float and others sink? A creative simulation allows learners to adjust mass and volume of an object to affect its buoyancy in water. A graph records the effect of each manipulation.
Curated OER
Sink or Float?
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...

How Does the USS Alabama Float?
Learners investigate buoyancy. For this buoyancy lesson, students apply the Archimedes Principle of Buoyancy to the experiment conducted in class to determine how battleships float.
Curated OER
Archimedes' Principle
Students examine the relationship between density and buoyancy. In this physics lesson students use Archimedes' Principle to complete calculations on buoyancy and a lab activity.
Curated OER
Dive In
Students study how buoyancy, pressure, and light can effect the work of underwater scientists. In this marine science lesson students complete a lab that allows them to better understand how pressure varies with altitude and depth.
Curated OER
Properties of Matter: "Sink or Swim"
Third graders recognize that different materials have different properties which can be observed such as texture and bouyancy, and compare and contrast, through observation, ability of some objects to float because of action of...
Curated OER
Condiment Diver: The World's Simplest Cartesian Diver
Young scholars examine buoyancy. In this density lesson students form a hypothesis, collect data and draw a conclusion using the data.
Curated OER
Come On Down!
Students research the implementation of a research vessel used for ocean exploration. In buoyancy lesson students will construct a device that shows neutral buoyancy.
Curated OER
Sink or Float
Students explore water properties by conducting a class experiment. In this buoyancy lesson, students make predictions as to whether or not specific objects will sink or float in water. Students conduct the experiment and record their...
Curated OER
Technology of the Deep: Experiments with Buoyant Forces
Young scholars 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.
Curated OER
Concrete Canoes
Students explore and analyze the relationship of buoyancy and displacement needed to make an object float. They examine various boat designs, then design and build clay and aluminum boats that hold a cargo of marbles.
Curated OER
Beneath the Sea
Students build a model of a submersible that will allow them to explore ballasts and how they operate. In this hands on lesson students participate in an activity that shows them how to control buoyancy.
