Get Down With Density

Density: the reason a giant pumpkin will float, but a tiny cranberry won't. Lesson begins with a demonstration of two of the same-sized cubes having different densities. Then pupils take eight cubes, each of the same size, and have to...

Are atoms too small to be isolated? Answer this question and more as you provide young chemists with the tools to conduct a hands-on activity demonstrating atomic mass. Pupils explore the mass of copper and aluminum, compare Dalton's...

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

Young scholars learn how to measure the density of metals. In this density of metals lesson plan, students measure the density of various metals in order to determine what metals were substituted in a king's crown, scepter, breast plate...

In this density graph learning exercise, middle schoolers graph data displayed in a chart. Students also calculate the density of each metal shown in the graph. Middle schoolers answer questions about which detail is more dense.

Students realize that density exists. They develop a mental model of density-to realize that something is going on that they cannot see to account for differences between materials.

From hydrogen to ununoctium, this collection of videos has everything you need to begin teaching about the periodic table. Offering descriptions of each element and interesting experiments demonstrating their properties, this resource is...

What are alloys, and why do we use them? Through a series of interactive puzzles, scholars examine the components and uses of several common alloys. The accompanying teacher's resources provide support in using the lesson, printable...

Students conduct a series of experiments on water electrolysis. In this chemistry lesson, students explain what happens to the molecules during the process. They cite real world applications of electrolysis.
