Density comes to life as investigators place soda cans into containers of various liquids to find if they sink or float. They layer different density liquids, compare densities of different gases, and more. A total of six different...

Engage young scientists in the upper-elementary and middle school grades with this collection of simple experiments. Whether you're teaching about heat transfer, density, or potential energy this resource has a lab for you.

Keep your class afloat with a hands-on density lesson plan. The challenging lesson plan has learners experiment with different materials to compare their densities. They learn that increasing or decreasing the amount of the material...

Continuing with the concept of volume and its effect on density, learners now work with a piece of clay to see if they can get it to float in water. This is a memorable end to a seven-part investigation of density. Make sure to check out...

Larvae transportation on the New England seamounts is based on the density of the water. Scholars calculate density and graph salinity versus temperature to better understand the distribution of organisms in a water column....

Most scholars associate density with floating, but how do scientists determine the exact density of an unknown liquid? The third lesson in a seven-part series challenges scholars to find the mass and volume of two unknown liquids. Each...

Earth's vast ocean is full of mysteries! Science scholars discover the big-picture properties that influence its characteristics at different latitudes using a lesson from PBS's Weather and Climate series. After completing a background...

Math scholars of many ages examine the concept of population density and then discuss the significance of the population densities of Minnesota and China. They figure the population density of their school.

Students examine world population density and population distribution. They create pie charts showing population distribution and analyze population patterns in the United States and major regions of the world. They identify...

Seventh graders discover the definition of density through a demonstration using ethanol and ice cubes and a class discussion using a SMART Board to illustrate formulas and calculations. Students finish the lesson by practicing...

Using a dry cleaner bag and a blow dryer, create a hot air balloon! The materials list suggests obtaining one dry cleaner bag per student, but since this is probably inconvenient, consider doing this as a demonstration during a lesson on...

Learners discover the property of density while participating in a lab exercise. In this scientific measuring lesson, pupils utilize a scale to measure the density of different metal materials. They document their work and present their...

There are underwater rivers that flow on the ocean floor thanks to a difference in density. Scholars learn about the density in both liquids and solids in the second lesson of an 11-part series. They then determine the density of water,...

Explore the concept of density within states of matter—gases, liquids, and solids—through a group experiment in which young scientists test objects' texture, color, weight, size, and ability to sink or float.    

Students determine the density of different substances. In this physical science lesson, students rank them according to their density. They discover the relationship between volume and density.

Students watch the teacher do a demonstration of density with diet and regular soda. Note: try this first, as different types of artificial sweetener have different densities. Students discuss density and volume. They discuss "Relational...

Students find the density of two substances. For this density lesson plan, students determine the density of water and ethyl alcohol and compare their densities. They enter their data into the computer to produce a class compiled graph....

Students make calculations of population density to recognize the stressful conditions experienced by European ghetto dwellers due to high population density and scarcity of resources.

Students set up working models demonstrating lake turnover and the formation of deep water masses in the oceans.

Create layers of water. Pupils investigate different densities of colored water caused by salinity by trying to stack layers of water. Scholars compare two water samples to determine which is the most dense. As the class members work...

Learners define the terms "mass," "volume," and "density." The relationship between these three terms is established. They observe the differences between Regular and Diet Coke. They develop an hypotheses about why a can of Regular Coke...

This is the grown-up version of the classic "float an egg in salt water" experience, plus an experiment in soap making. High schoolers explore density, but more importantly, practice accuracy, precision, and the use of significant...

First, young chemists practice polymer identification by density and flame tests. With the data collected, they propose a method of separating polyethylene from other plastics and determine what property makes it desirable for recycling....

Even middle schoolers still enjoy experimenting with bubbles! They execute a series of experiments enabling them to distinguish between convex and concave surfaces, explore the properties of buoyancy, surface tension, and density,...
