Reinforce concepts and encourage learner engagement with a collection of math games, science experiments, and cross curricular activities. In one fun resource, learners sort objects, keep a diary of everyday fractions, play a game using...

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...

Teach the masses about the metric system with this hands-on measurement lesson. Given a fruit or vegetable, learners estimate, measure, and convert its mass using the metric units gram and kilogram.

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...

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...

Learners will shout "Eureka!" in this quick but deep activity replicating the famous bathtub experiment of Archimedes. Given the scenario of a king with a suspected fake crown, young investigators develop formulas using density to...

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. 

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...

Will the block float? Pupils take measurements to calculate the volume of various blocks of different materials. Using a scale, they determine the mass of each block and then calculate their densities. Scholars finish by ranking the...

Every child's dream: stuffing as much candy into a bag as possible. Doing this, though, requires a nice sturdy bag. Scholars design the sturdiest bag they can and test the limits of those bag using a sweet treat!

Using helium as an example of propane, physical science middle schoolers experiment with and graph the relationship between temperature and volume in gases. In a whole-class demonstration, they show how molecules behave under different...

Sugar isn't good for you, but it's great for yeast! Scholars design an experiment to investigate how variables affect the rate of sugar consumption in yeast. The last installment of a nine-part Life Science unit considers how scientists...

This site allows you to convert weight/mass measurements. For example converting tons to grams. CCSS.Math.Content.3.MD.A.2 Measure and estimate liquid volumes and masses of objects using standard units

Students will use two different methods to determine the densities of a variety of materials and objects. The first method involves direct measurement of the volumes of objects that have simple geometric shapes, while the second uses the...

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...

Metric units for volume, mass, length and temperature are explained to a cute little alien called Maggie. There are lots of real life examples for comparison that younger children will understand.

Students investigate the relationship between density of an object, its mass and its volume. They use mass and volume measurements to determine the density of pennies. They compare the density of pre-1983 and post-1984 pennies.

Use this converter to find equivalent units for a measure. You can convert measures for area, length, weight, temperature, and volume.

Students act as chemical engineers and use LEGO MINDSTORMS NXT robotics to record temperatures and learn about the three states of matter. Properties of matter can be measured in various ways, including volume, mass, density and...

This unit could be used as supplementary material for a topic on measurements. It has good examples with illustrations and some interactive activities.

Disappearing Wetlands: Explore the relationship between mass, density, and salinity by measuring the mass and volume of four saltwater solutions of increasing strength.
