New ReviewA short video introduces the triangle that illustrates how to find any value given the other two in the density formula. Class members use the triangle to work several problems to find the mass, volume, or density of an object.

New ReviewWhile the AP Physics 2 test maintains the reputation for one of the most difficult AP exams, scholars feel better prepared after practicing free-response questions on currents, conservation of energy, and displacement. The College Board...

New ReviewCompounding is dividing units. Pupils practice using compound measures such as units for speed and density to solve problems that range from straightforward speed problems to those requiring conversions. The last few items challenge...

A good concept map requires high thought processes. This makes it a great tool for teaching and evaluating your pupils. A helpful article describes a great approach for teaching young scholars the art of concept map building and how best...

Flat, positively curved, or negatively curved ... what is the true shape of the universe? Scientists use many indirect measurements to base their theories on the shape of the universe. Using an installment from the SciShow Space series,...

Did you know many insects use cohesion or surface tension to walk on water? Using a presentation, scholars learn the more important properties of water. It extends into the concepts of solutions, suspensions, pH, and more.

Pack the lesson into your plans. Young mathematicians learn about packing and optimization with the context of circular paving stones. They use coins to model the paving stones, and then apply knowledge of circles and polygons to...

It's time to mix things up! Introduce biology scholars to the latest topic in marine research—invertebrates! The third installment in a five-part series of Invertebrates lessons explains the hypothesis that tiny, migrating shrimp are...

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 plan from PBS's Weather and Climate series. After completing a...

Swirling and churning, the waters of the North Atlantic play a vital role in Earth's climate! Discover the many factors that produce circulation using a multimedia lesson from PBS's Weather and Climate series for high schoolers. Scholars...

Learners calculate the pixel density of a specific cell phone using the concept of similarity. They use information from the cell phone's website to make their calculations and then compare their results to the posted information.

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

What can your class tell about a wave just by looking at it? Using a simulation, physics pupils work through a series of case studies to determine the effects of speed, frequency, and density on waves. Part of a larger playlist on waves...

That would make a lot of cans! Learners analyze a photo of a truckload of aluminum to determine its value. The provided information includes the weight of a smaller block and the dimensions of the larger block. It's up to your pupils to...

Clay itself sinks, but clay boats float. Why? Young engineers build clay boats to learn about buoyancy. They test the weight the boats can hold using washers and then tweak their designs to make improvements, following the engineering...

Clay's as good a material as any to build a boat, right? An introductory lesson sets the stage for two activities associated with buoyancy. The first involves building boats out of clay, while the second uses these boats to measure the...

Don't be dense—use a robust resource. The second installment of a five-part Floaters and Sinkers unit has learners determine the densities of several objects. As part of the activity, they learn the displacement method for finding...

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...

An engating lesson relates mass and volume to better understand density. Young scientists explore and experiment with floating and sinking as well as density cubes. Then, they solve how to make a sinking item float.

How can something as vast as the universe also be flat? Go beyond the Big Bang Theory using a video from an expansive physics playlist. Topics include the expansion and inflation of the universe, why opposite sides of the universe are...

Assume the role of Canadian border control! The percent of alcohol and density of a solution are related. Young scholars use this fact to classify solutions by their alcohol content to determine if they meet Canadian import laws.

Mislabeled bottles can cause a dangerous situation! Young chemists design a method for determining the true contents of a solution in a virtual lab activity. Their study of density helps them identify the makeup of the solution.

A metal's density could be considered its fingerprint! A virtual lab activity has learners calculate the density of a sample of metal to make its identification. The simulation allows individuals to perform the measurements as if they...

Recreate the secret Coca-Cola formula in a virtual lab. Young scholars create the solution and then calculate sucrose concentrations in terms of percent mass, molarity, molality, and mole fraction. Then using density, learners determine...
