Curated OER
Density and Mass
Learners experiment to find which liquids are more dense. In this density and mass activity, students predict and then test objects to observe and measure their density. learners observe which items sink and float. Students complete...
Curated OER
Light and Water
Third graders experiment with coins and water to explore light rays. In this light and water lesson, 3rd graders work in pairs to observe what happens with a coin in water or how it appears based on the density of the water....

Using Soap Foam to Alter the Density of Plaster of Paris
Middle schoolers determine the density of Plaster of Paris that has been prepared with a foam generated from dishwashing liquids and shampoo.
Curated OER
Density
Students explore the meaning of density. In this density instructional activity, students use interactive whiteboards to review definitions regarding density and compare the density of selected objects.
Curated OER
Water Density
Students identify and analyze the concept of density using the formula, density equals mass divided by volume. They review the differences in salinity levels of the ocean and note that the changes in density are caused by wind and...
NOAA
The Oceanographic Yo-yo
How does chemistry help deep-sea explorers? Part four of a five-part series of lessons from aboard the Okeanos Explorer introduces middle school scientists to technologies used in ocean exploration. Groups work together to analyze data...
Curated OER
Density of Liquids
Students explore the density of liquids. In this scientific inquiry lesson plan, students discover the density of water, corn syrup, and cooking oil through an experiment. In addition, students will draw and label pictures of the...
Curated OER
Discovering Density
Students explore the physical properties of density. In this hands-on activity, students calculate density and distinguish between intensive and extensive properties.
Curated OER
Testing Density of Various Soap Products
Students have the opportunity to observe, measure and analyze the density of aerosol shaving creams and foams generated from shampoo and dishwashing liquids or detergents.
Curated OER
8th Grade Earth Science: Density
Students draw upon their prior knowledge of the density of water and practice writing a hypothesis, making an observation, and analyzing data while watching a density demonstration.
Curated OER
Density and Buoyancy Lesson Plan
High schoolers investigate why some objects float or sink in water. For this physics lesson, students calculate the density of clay ball using a mathematical equation. They write a complete lab report about the experiment.
Curated OER
Student Exploration: Density Laboratory
In this density laboratory instructional activity, learners complete 2 prior knowledge questions, then use the "Density Laboratory Gizmo" to complete several activities, answering short answer questions when finished.
Curated OER
Earth: The Water Planet
Students elicit data on the water cycle, ocean topography, and island formation in this six lesson unit. The ocean floor and the properties of water are examined through a variety of discussions and hands-on experiments.
Curated OER
Mass, Volume and Density
Students compare and contrast the mass, volume, and density of various objects. They use a triple beam balance, measure and record the volume of a cup of water, and discuss the results.
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
Density Discoveries
Students participate in Density Discoveries, which is a hands-on learning opportunity for students to find the mass, volume, and density of solid matter.
Curated OER
Water and Ice
Students explore the states of matter. In this physical science lesson plan, students observe what happens to water when it freezes and record observations. Students then observe ice when it melts and record observations.
Curated OER
Seashore Explorers
There are three separate lessons within this resource that can be used together, or that can each stand alone. In the first, five simple activities allow junior scientists to examine the amazing properties of water. In the second, they...
Normal Community High School
Golf Ball Lab
The first golf balls were made of wood and would only last for a few games. Modern golf balls last a lot longer but they don't float. The presentation provides the directions for a lab to determine the minimum amount of salt needed to...
American Chemical Society
Investigating the Line
Note that this instructional activity is best paired with the preceding instructional activity in the unit. In that instructional activity, elementary physical scientists observed that the color coating of M&Ms® candies do not mix...
Curated OER
Density Currents
Students experiment with currents caused by temperature variations that simulate the origins and flow of polar bottom currents. They discover water density is affected by temperature and salinity, resulting in deep water currents.
Curated OER
To Float or Not to Float - A Lesson on Density
Students observe and experiment with the concept of density. This is done using a simple experiment that helps them to apply scientific principles of observation and proving a hypothesis.
Curated OER
Ocean Currents
Students discover the geography of Earth by analyzing water currents. In this oceanography lesson, students create visual references on a map of the globe where and why major ocean currents are moving water. Students conduct a water...
Curated OER
Mixing Oil and Water
Students explore physical science by participating in a class experiment. In this chemistry lesson, students discuss what they predict will happen when cooking oil and water are blended together. Students utilize a plastic bottle, food...
