Density Problems
In this density worksheet, high schoolers use a table showing the density of different substances to identify substances or calculate mass or volume.
Perkins School for the Blind
Volume, Mass, and Density Boxes
Mass and density are difficult topics for kids to understand, and even more difficult when you have visual impairments or blindness. Learners will make boxes and fill them with cotton, sand, or crushed paper. They will feel the density...

Rock Density Lab
Students use a balance and weigh a rock sample. They weigh the rock suspended on a sling in a glass of water. They tabulate the rock's density using the two weights and compare the density of various rocks of similar sizes.

Floaters and Sinkers
Whatever floats your boat. Young engineers learn about density by measuring the masses and volumes of boxes filled with different materials. Using their knowledge of densities, they hypothesize whether objects with given densities will...
Curated OER
Sea Water Mixing and Sinking
Students investigate the role of temperature and salinity in determining seawater density. They use a Temperature-Salinity Diagram to examine the effects of mixing on density.
Houghton Mifflin Harcourt
Rearranging Algebraic Equations
In this density worksheet, students review how to rearrange the equation for density to solve for mass or volume. Then students complete 4 problems.
Curated OER
Why Do Some Things Float?
Students recognize that density determines whether objects sink or float. For this sink or float lesson, students experiment with plastic in three liquids. students drop their objects into the liquids and observe and record their results.
Curated OER
Lake Strata and Internal Waves
Use the classic density demonstration of placing a cola, a clear soda, and a diet soda into a tank of water. Then let learners attempt to pour some of the soda into layers in a clear container. The procedure explains a thermocline, and...
Alabama Learning Exchange
Float or Sink?
Experiment with mass and density as scholars figure out what makes things float or sink. First, they watch a podcast introducing these concepts. Be sure to use the comprehension question to test their understanding. Young scientists...
Curated OER
Come On Down!
Begin with an introduction to famous deep-sea submersibles. Learners work in groups to gather information on different vessels and then share with the class. Each group then uses water displacement to help calculate the density of...

# 15 A Search for Automated Plastics Recycling Separation
Students are challenged to investigate the physical and chemical properties of plastics and use them to design a system that could be used to separate them. 1st year chemistry students use density for separation, students gathered...
Curated OER
The Stone Boat Mystery
Students design and execute a lab through which they study the distinctions between density, buoyancy, and volume.
Curated OER
Count Marsili & the Mediterranean Current
Students integrate history and science while discovering how salinity affects the density of water. After a lecture/demo, students work in groups to complete a lab activity that demonstrates how salinity affects the density of water.
Curated OER
Bubble and Boyle
Middle-schoolers still enjoy playing with bubbles! In this series of eight laboratory activities, science learners explore convex and concave surfaces, angles, gas laws, buoyancy, density and more!
Curated OER
#17 Determining the Accuracy of Selected Laboratory Glassware
Students calculate the volume of a specific mass of water placed in selected pieces of common laboratory glassware, using the density formula. They then determine the accuracy of the volumetric measurement for selected pieces of...
Curated OER
How Big is Big?
Geography learners compare and contrast population densities throughout the world. Using maps, they estimate the relative size of the world's regions and populations. They develop analogies to discover the world they live in and...
Curated OER
Attack of the Raging River
Students explore mass and volume. In this mass and volume lesson, students pretend to be on a hike and have lost their way. Students must cross a river get back on track. Students must use mass, volume, surface area, density, property...
Curated OER
Organic Molecules Detected on Distant Planet!
Here is a planet worksheet in which learners read about organic molecules detected through spectral lines of the planet Osiris. They calculate the mass, the volume and the densities of common ingredients for planets including Osiris and...

BioFuels: The Chemistry and Economics of Alternative Fuels
Junior chemists manufacture biodiesel in the lab. In this exercise, they check the purity of the biodiesel using thin layer chromatography. They also calculate its density and heat of combustion. They are sure to rise to the challenge...
Curated OER
Taking the Boat to Manaus
Fifth graders apply the concepts they know regarding mass, volume and density in the previous activities to design a boat. Student teams must make a boat which can travel the waters of the Amazon Rainforest. Each group makes a...
