The Causes of Differences in Density
Students explore how density changes. Students read an article on density. They observe a ball and ring demonstration and discuss the outcome. Students draw models of the demonstration and explain what happened.

The Role of Density in Sinking or Floating: Relational Causality
Students consider density and how it affects sinking and floating. Students make predictions, test liquids, and observe why some liquids sink and others float. They perform experiments to determine relational causality and how liquids...
Curated OER
The Causes of Differences in Density
Students explore what causes differences in density. They observe an models depecting atoms, compounds, and molecules. Students determine if there is air in between atomic bonds. They study the structure and spacing of molecular bonds.

Causal Patterns in Density Phenomena
Students investigate the relationship between volume and mass in different liquids such as vegetable oil, rubbing alcohol and water. They measure the mass of several different volumes of each liquid and then graph the results as well as...
Curated OER
The Causes of Differences in Density
Students explore the causes of differences in density. Students choose objects, measure the mass and volume, and calculate the density of each. They perform additional density experiments to model atoms and their correspondence to...
Curated OER
Defining Density as a Relationship
Students discover that density is considered a property and that cutting an object in half does not affect its density. They examine the densities of many common substances and make connections.
Curated OER
Defining Density as a Relationship
Students investigate density and its relationship to air and gas. Students perform experiments to determine if gases have mass. They explore possible ways to figure out the density of gases.
Curated OER
Defining Density as a Relationship
Students review the relationship between mass and volume is constant for a pure substance under standard conditions. They complete mass and volume worksheets using formulas for calculating density.
Curated OER
Visualizing Density: Density is Non-obvious
Learners explore models of density; wooden balls and marbles discussing whether they think the volume and mass are the same or different. They then compare the density of a loaf of bread that is squished and one that is not compressed.
Curated OER
Salt Water Wedge
Students conduct an experiment to observe the properties of both salt and freshwater. They explain why freshwater will stay at the surface while salt water will travel up a river bottom because of density. Students also research the...
Curated OER
Density Balloon
Students experiment with density using a mylar balloon and hair dryer in an experimental setting. The concept of density is often confusing to students and this activity gives them an introductory insight into the concept in a fun way.
Curated OER
Floating Pencil
Students discover how salt water makes a pencil float better than freshwater by measuring and comparing the lengths of the portion of the pencil that floats above the water surface. They then determine if an unknown water sample is...
Curated OER
Rising Waters
Fourth graders rank balls by size from smallest to largest and from lightest to heaviest and then by how much they made the water rise. They then discuss why certain balls make the water rise higher than do other balls.
Curated OER
Displaying Data
Students create a display map with data from a previous instructional activity. They incorporate graduated marks that identify areas of the school grounds that are good for planting based on density.
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
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
Diving Raisins
Young scholars 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
More Volume Please! Don't Be Dense!
Fifth graders determine volume and density through their knowledge of mass, volume and density.
Curated OER
Density Destiny
Sixth graders measure and investigate the densities of several objects. They, in teams, determine the mass and volume of each of the 5 objects and record the measurements in the data table.
Curated OER
Mass, Volume and Density
High schoolers 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
Using Soap Foam to Alter the Density of Plaster of Paris
Students determine the density of Plaster of Paris that has been prepared with a foam generated from dishwashing liquids and shampoo.
Curated OER
Testing Density of Various Soap Products
Middle schoolers 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
How Does Altitude Relate To Density?
Students demonstrate an understanding of the properties of matter by applying them to density, pressure, and temperature. The educational software program, "Foilsim" is used in this inquiry.
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.
