How Does the USS Alabama Float?
Students investigate buoyancy. In this buoyancy lesson, students apply the Archimedes Principle of Buoyancy to the experiment conducted in class to determine how battleships float.
Curated OER
Floating Soap
Learners explore the density of soap. In this science instructional activity, students conduct an experiment to find which types of soap will float. Learners make a hypothesis and record their observations.
Curated OER
Make An Egg Float!
Students analyze density. In this density activity, students experiment with floating an egg. Students discover that salt added to water changes the density of the water allowing an egg to float.

Science: Different Levels of Density
Students observe experiments in density and describe the results. In the experiment, milk, corn syrup, and oil are added in different orders to three glasses, while one other glass contains only water. As objects are dropped into each...

Science - 'Why does the wind blow?'
In this earth science worksheet, students read a poem about the wind and learn why the wind blows. After reading the poem and informative paragraphs that follow it, students answer 2 questions regarding the information they read....

Cody's Science Education Zone
Students observe a scientific experiment and pose a hypothesis. In this scientific inquiry lesson, students make predictions about the combination of alcohol in water and how it will affect a floating ice cube.
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
What Floats Your Boat?
Students are introduced to the concept of buoyancy. The Video used in this lesson plan demonstrates and explains the characteristics of objects that sink and float. It presents the concepts of displacement, weight, and buoyancy.
Curated OER
Types of Marine Debris
Students conduct an experiment. In this marine debris and environment protection lesson, students categorize trash into piles, predict whether these trash items will sink, float or be picked up and carried by the wind and then test...
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. In this graphing lesson plan, student first predict how much water is wasted. That night they test it out at home and the next day...

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.

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...
University of Waikato
Temperature, Salinity and Water Density
The difference between sinking and floating may be a little salt. Young experimenters analyze the effect of salt and temperature on the density of water. They use their results to predict the effect of climate change on ocean ecosystems.

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.

Scuba Training
How does a scuba diver control whether they sink or float? Scholars observe the relationship between absolute pressure and depth below the surface in an undersea simulation. They control the diver size and depth to center of mass to...

Science - "Why does it float?" - Exploring the Concept of Density
In this density worksheet, students read about density, volume and mass. They then use what they learned to answer the 8 questions on the page. The answers are on the last page.
Curated OER
Give Me a Tall Ship
Sixth graders develop an understanding of floating, sinking, density, and buoyancy and apply it to the design of testing of ships.
Curated OER
WHY DO SOME THINGS FLOAT WHILE OTHERS SINK
Students explore how density can cause things to sink or float by experimenting with a jar, oil and corn syrup.
Curated OER
Density and Buoyancy Lesson Plan
Students investigate why some objects float or sink in water. In this physics activity, students calculate the density of clay ball using a mathematical equation. They write a complete lab report about the experiment.
Curated OER
What are Properties of Wood?
Students use hands on scientific observation to determine characteristics of wood. They work directly with the materials and record their observations. Students test if wood absorbs water, if wood floats or sinks, and if all wood...
Curated OER
Density and Buoyancy Experimental Design
Students must plan, design, and conduct an experiment that answers the scientific question: "Come up with a question that addresses the factors (variables) of the water and its effect on whether an object floats or sinks."
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
Soap, Wood, and Water
Students measure the properties of two different types of soap and wood and calculate their densities. Then they predict whether or not whether or not each object would float or sink in fresh or salt water.
Curated OER
Can You Make A Penny Float?
Students explore the concept of density by trying to make a penny and other materials float.
