Mass and density — aren't they the same thing? This activity has groups use balance beams and water displacement to measure several objects. The pupils use the measurements to calculate the density of the objects. 

Groups suspend objects within layers of liquids to determine the densities of different liquids and compare them to the densities of objects calculated in Part 1. The groups then carefully test their calculations by layering the...

In lab groups, young scientists place aluminum cans with a bubble-solution cap into different temperatures of water to see what size of bubble dome forms. As part of an atmosphere unit in preparation for learning about convection...

Seventh grade scientists weigh in on the concept of density. In a nutshell, they participate in the following activities: Measurement of the mass and volume of fruit in order to compare densities Measurement of the mass of oil and water...

Let there be light. The last installment of a seven-part series has pupils conduct an experiment on light attenuation through different numbers of transparency sheets. They then relate the results back to how X-rays measure bone density.

See the direct relationship between pressure and temperature using these classic science toys. As individuals hold the glass bulb, the liquid inside reaches it's boiling temperature, which is just a bit above room temperature. As the...

A lab experiment that shows students that different molecules melt in different ways. This lab also allows students to practice calculating and finding density, mass, and volume. Lesson plan includes lab handout for students.

Concluding a two-part lab activity, students use triple balance beams and graduated cylinders to take measurements and calculate densities of several household liquids and compare them to the densities of irregularly shaped objects (as...

In this first part of a two-part lab activity, students use triple balance beams and graduated cylinders to take measurements and calculate the densities of several common, irregularly shaped objects with the purpose to resolve confusion...

Students will determine what an unknown substance is by finding mass, volume, displacement, and density of an object. Students will also create a report which will require them to read a graph, interpret data, calculate averages, and...

Students determine the mass and volume of soil samples and calculate the density of the soils. They use this information to determine the suitability of the soil to support a building foundation.

Help students brainstorm and find a solution as to why Diet Coke floats and Coke sinks. Student will learn to define what density is as they engage in this creative lab. This resource is in PDF form; requires Adobe Reader.

A collection of over 30 virtual chemistry problems with accompanying interactive activities. Each problem includes a word file for potential differentiation in your classroom.

A lab activity to show students how different densities of liquid layer on top of each other by using four different colored liquids that contain different levels of salinity. This activity can also be used in an ocean unit where...

A simple lab activity to demonstrate that ocean currents are influenced by changes in water density.

Students contrast the densities of oil and water in this lab activity. Can be done in groups or individually. This resource is in PDF form; requires Adobe Reader.

In this activity, students use the virtual lab to prepare a sucrose solution for a soda recipe. They next calculate the concentration of their solution in terms of molarity, percent mass and density. Finally, they compare the density of...

This is a good source of basic information about density currents in water. It includes simple activities you can do to demonstrate these currents.

In this activity, students use the virtual lab to create dilute solutions from a concentrated stock solution of acids or bases. They must first calculate the correct volumes of concentrated acid solution and water to mix together to...

Engaging hands-on science lessons for grades 2-6 on the properties of different materials.
