Density

For Students 7th - 12th Standards
A 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.

Density (Liquids)

For Teachers 6th - 12th
Using a graduated cylinder and triple beam balance, middle schoolers measure the volume and mass of four different liquids. They use the values to compute densities. In a separate activity, they experiment with Cartesian divers and learn...

Density (Solids)

For Teachers 4th - 7th
Elementary and middle school physical science learners explore density in a hands-on lesson. They measure the mass and calculate the volume of different metal and wood blocks. From these two values, they compute the density for each....

Density of Water

For Students 6th - 8th Standards
We know solids have a density we can measure, but what about liquids? Lesson explores this concept and allows scholars to explore the relationship between volume and density. Graphing and analysis questions round out the activity.

Density

For Teachers 6th - 12th Standards
Why do some large objects float while other tiny objects sink? Simulation relates mass and volume to density. After repeated measurements with known substances, scholars must identify a mystery substance by calculating its density.

Investigating the Effect of Salinity on the Density and Stability of Water

For Teachers 6th - 8th
Water with varying amounts of dissolved salt are dyed and then used to compare densities. The objective is to discover the effect of salinity, and therefore density, on ocean water on the stability of the ocean. Many branches of science...

Density

For Students 6th - 8th
Certain things just do not mix, including liquids of varying densities. Learners collect data to determine the densities of several liquids. They then use the density information to predict the type of liquid.

Determining the Density of a Liquid

For Teachers 8th - 10th
Learners find the density of diet soda and regular soda. In this density lesson plan, students measure the mass of a graduated cylinder with 10 different volumes of each soda. They find the mass of the liquid alone and use the volume to...

Defining Density

For Teachers 3rd - 8th
Three simple activities kick off a unit investigation of density. Your physical scientists make observations on the volume and mass of wood, water, and rocks, and make comparisons. Though this is written for grades three through eight,...

Determining the Molar Mass of a Gas

For Teachers 9th - 12th
Students determine the molar mass of a gas. In this molar mass of a gas lesson plan, students use the vapor density of an organic solvent to determine its molar mass. They vaporize the solvent and collect the vapor. Once it is cooled...

Mass and Volume

For Teachers 7th - 12th Standards
Don't be so dense that light bends around you; study the relationship between mass and volume instead. Young chemists measure the density of a variety of liquids and solids. A reading passage and analysis questions introduce pupils to...
