Curated OER
Floating Soap
Young scholars explore the density of soap. In this science lesson, students conduct an experiment to find which types of soap will float. Young scholars make a hypothesis and record their observations.
Curated OER
Sink or Float
Students construct clay boats and predict whether the boats will sink or float. Students will hypothesize what caused the boats to sink or float.
Curated OER
Dragon Boats
Students create a model boat. In this art lesson, students identify what makes a boat float and use milk cartons to create their own boat.

What's The Matter: A Sinker or Floater?
Students conduct an experiment. For this water lesson, students watch the lesson "Float and Sink" on an interactive website. Students learn how to test items in water and then work in groups to test their items. Students discuss their...
Curated OER
I'm Warm Now
Third graders graph how much water is wasted while waiting for it to get warm in the spigot in the sink. For this graphing lesson plan, student first predict how much water is wasted. That night they test it out at home and the next day...
Curated OER
Sink or Float
Students experiment with different objects to test if they sink or float. They predict what the object will do before it is put into the water. They are allowed to play with the items after the experiment is over.
Curated OER
Sink or Float Experiment
Students participate in an experiment to determine which objects float or sink. They use different amounts of salt for the objects and discover as the salt content increases, objects will float. They record their predictions and what...

Anthony's sink or float game
Students explore the concepts of float and sink by playing a game where they build things on mud, water, rock and jelly. In this Anthony's sink or float game lesson plan, students discover what materials remain strong in various...

Determining Densities
Don't be dense—use a robust resource. The second installment of a five-part Floaters and Sinkers unit has learners determine the densities of several objects. As part of the activity, they learn the displacement method for finding...

Science: Floating and Sinking Objects
Second graders discuss why some objects float while others sink. They examine various objects and predict whether or not they will sink or float. Students discover the properties needed for objects to float.
Curated OER
Ice Floats
Learners 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.
Curated OER
Why Cheerios Don't Sink
Students investigate Archimedes' Principle and show how it relates to density. In this Archimedes' Principle lesson plan, students experiment with a beaker of water, a Styrofoam "boat" and a weight. They predict what will happen when the...
Curated OER
Floating and Falling Flows
Students discover fluid dynamics related to buoyancy through experimentation and optional photography. Using one set of fluids, they make light fluids rise through denser fluids. Using another set, they make dense fluids sink through a...
Curated OER
Sink or Float: Exploring the Laws of Buoyancy
Students explore the relationship between density and buoyancy. After watching a video explaining buoyancy, students discuss displacement and floating. Students have a raft building competition. Afterward, they conduct experiments to...
Curated OER
Density - To Float or Not to Float? That is the Question!
Students investigate how to find the density of fluids and solids using math. Students also learn how to find the density of regular and irregular shaped objects.
Curated OER
Can You Make A Penny Float?
Pupils explore the concept of density by trying to make a penny and other materials float.
Curated OER
Buoyancy: What will float and what will sink
Students write and explain why an object sinks or floats. In this buoyancy lesson students demonstrate how items float or sink and graph the results.
Curated OER
Floating
First graders discuss with the teacher if everything will float in water. They observe a marble and determine whether it will float making predictions as a class. After observing the results, they discover that liquids exert an upward...
Curated OER
Floating Oranges
Pupils get into groups or watch one demonstration of the game. They observe an orange floating in the pool, pretending it is a little boy/girl wearing a life jacket. Next, they watch as the orange is peeled and thrown back in, with the...
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
Buoyant Behavior
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...
Curated OER
Density
Second graders watch a demonstration and complete an experiment to determine how an objects' density allows it to float or sink. They work in small groups to assimilate the characteristics of items that float as opposed to simply...
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.

Will the Pumpkin Sink or Float?
Learners participate in a sink or float activity using pumpkins.
