Learners find the density of two substances. In 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....

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,...

Students observe 2 demonstrations of density. In this density lesson plan, students observe a vial with various substances of different densities. Students then observe the differences between a diet coke and a regular coke can when on a...

Students find the density of objects by finding their mass and their volume. In this density lesson plan, students determine the mass of objects, the find the volume by using formulas or by water displacement and they calculate the...

Students investigate density using film canisters filled with different density materials and larger objects of varying density. In this density lesson plan, students discuss the concept of density and rank film containers from dense to...

Students explore the concept of density. In this density lesson plan, students determine the density of a crown and a sample of clay. They hypothesize about the densities of 4 liquids they are given including molasses, cooking oil, a red...

Students investigate the concept of density by observing demonstrations. In this density lesson plan, students make observations while the teacher demonstrates the Cartesian diver, a density column, a candle trough, a wave bottle, an...

Students experiment with objects of different densities. In this density lesson, students examine same-sized objects with different weights, then look at a teacher explanation of density. Students make wave bottles and a density jar to...

Students work in groups to compare the density of different liquids.  In this density lesson, students use cooking oil, liquid detergent and water to measure density.  Students record their results and check the accuracy of...

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...

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...

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...

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...

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...

Students explore physical science by conducting an in-class experiment. In this density instructional activity, students define vocabulary terms dealing with physics and discuss their knowledge of density. Students conduct several "sink...

Is your current lesson plan for salt and freshwater literacy leaving you high and dry? If so, dive into part one of a seven-part series that explores the physical features of Earth's salt and freshwater sources. Junior hydrologists...

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...

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...

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...

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.

Turn your class loose to experiment with the different fat content in skim milk, whole milk, half and half, and heavy cream. This is a visually vibrant experiment, as learners drip food coloring on the surface of the products and measure...

Can you use X-rays to measure bone mineral density? This is the essential question that learners must answer in the first installment of a seven-part series. They brainstorm ideas about necessary background information and what they...

The arctic seas contain currents that are both warm (with high salinity) and cold (relatively fresh water) that circulate throughout the year. Through discussion, a lab, and a web quest, participants explore the impacts of melting and...
