Curated OER
Ice Floats
Students explore the changing density of water. In this physics lesson, students investigate how an object's density determines whether it will float or sink in water. They explain why this unique property of is important to living things.

Thermo and Fluid Dynamics of a Homemade "Lava Lamp"
Students construct their own lava lamp using simple substances. In this physics lesson, students explain how difference in density causes convection. They solve for forces and buoyancy using mathematical equations.
Curated OER
Build Your Own Submarine
High schoolers construct their own submarine following a certain procedure. In this physics activity, students calculate the density of objects using a mathematical formula. They explain why some object floats in water while some do not.

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
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...
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...
Curated OER
What Floats Your Boat?
This open-ended boat building exercise is meant to be part of a three-activity series on ships. Links to the other two lessons are included. This particular part is mostly a group lab activity in which they build a boat, find its load...
Curated OER
Sink It
Introduce your class to the concept of sinking and floating. In groups, they classify objects after making predictions about which materials will sink or float. They record their results and create graphs and charts to share with the class.
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...
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
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
Diving Raisins
Students hypothesize and observe what occurs when raisins are dropped in a carbonated liquid. They examine buoyancy and how density effects ascent and descent.
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
Day Six: Floater What Ifs
Students observe earth science by examining results from an experiment. In this buoyancy instructional activity, students practice floating different items in two different liquids and identify why certain objects will float and others...
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...
