Young scholars 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.

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...

Learners 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.

In this density learning exercise, students review how to rearrange the equation for density to solve for mass or volume. Then students complete 4 problems.

Students recognize that density determines whether objects sink or float.  In this sink or float lesson, students experiment with plastic in three liquids. students drop their objects into the liquids and observe and record their...

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...

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...

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...

High schoolers 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, high schoolers...

Students design and execute a lab through which they study the distinctions between density, buoyancy, and volume.

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.

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! 

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...

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...

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...

Use this art lesson to study insolubility and density. Combining water-based paint and mineral oil will cause a fun and interactive painting. This is a great art project to incorporate during a science unit.

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...

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...

NASA presents a mini-unit on distances in our solar system. It incorporates scientific concepts of gravity, mass, density, and payload while your aspiring astronauts also employ mathematics skills. They calculate speed, they determine...

Find the mass, volume, and density in five different equations with a straightforward worksheet. Each equation prompts kids to work through word problems of varying difficulty and to find the necessary measurement using different formulas.

Bone up on bone density. The second installment of the seven-part series has pupils read articles on two different websites to learn about bone density and its measurement, as well as X-rays and other imaging tools. A quiz assesses their...

What do logarithms have to do with bone density? Scholars learn that the equation for bone density includes logarithms. The majority of the third lesson of seven is devoted to logarithms and their properties.

Hop into a resource on Beer's Law. A PowerPoint presentation introduces Beer's law as part of calculating bone density from X-ray images in the sixth lesson in the series of seven. Individuals work on practice problems with this law and...
