Mass, Volume and Density

All 20 of the problems on the worksheet involve the computation of cubic volume or density. As long as your young scientists can apply the appropriate mathematical formulas, they will succeed in solving these problems. They are not...

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...

This sequence of slides is a fabulous introduction to the concept of density as it relates to mass, volume, physical impact, and interpretation. Various examples are given and your class will find the charts and procedures helpful in...

Change the density of water by adding minerals. The presentation discusses density—from the definition to calculations—and applies it to the real world. It briefly mentions specific gravity, and finishes by showing Archimedes' principle. 

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.

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.

Students 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...

Students perform an experiment to measure the density of tap water vs. salt water.

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...

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...
