Density Column Lab - Part 1
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.

The Inertial Balance
Students weigh objects using a triple beam balance. For this mass lesson, students use an inertial balance made with a metal rod to measure and graph vibrations of varying numbers of pennies in a bucket. References and discussion prompts...

Density Lab Activities
Students participate in several density lab activities in order to clarify the misconceptions that solids sink and liquids float. Students work with triple beam balances to find mass of objects to calculate density.

Matter and Energy
Does the change in energy of matter lead to a change in mass? Upcoming chemists compare the mass of equal-volume, but different-temperature liquids and materials both before and after a chemical reaction has occurred. In another...

Balancing Bottles
Students explore the Law of Conservation of Matter using effervescent tablets. In this mass and energy instructional activity, students investigate how mass is conserved in the reaction of effervescent tablets and water. They will...
Curated OER
Mass, Volume and Density
High schoolers compare and contrast the mass, volume, and density of various objects. They use a triple beam balance, measure and record the volume of a cup of water, and discuss the results.

Practice with Mass
Fourth graders investigate the weight/mass of a number of items using grams, and equivalents. They examine the use of a triple beam balance before massing objects including oil and water. They go over the weights they amassed and weigh...

Law of Conservation of Mass
Students work in small groups. They grab a handful of ice, and place the ice in an empty beaker of ice using a triple beam balance. Students heat up the beaker of ice over a hot plat until the ice has changed into water. They measure...

Using Density to Identify Wood Types
Young scholars identify different woods based on their density. For this density lesson, students use a triple beam balance to find the mass and a metric ruler for the volume. They look through various wood blocks and identify what type...
Curated OER
Mass
Students determine how mass is a property of an object that can be measured, and examine how size affects mass. They work with balances and determine what units of measurement are associated with mass. Finally, they determine the...
Curated OER
Denser Sensor
Fourth graders calculate density, compare densities of solids and liquids, measure liquids using a balance, and investigate the significance of density. They conduct an experiment to determine an order of densities, and complete a...

Density Column Lab - Part 2
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 liquids...

Project Geode
Young geologists attempt to predict the appearnace of a geode's internal structure based on how it looks from the outside, its mass, and its physical characteristics. In this geologly instructional activity, learners use scientific...
Curated OER
Cycles and Starting Mealworms
Here is a fascinating lesson about the life cycles of plants and animals, and other cycles found in nature. Learners explore the cycle of the moon, the tides, and other sequences of events in every day life. The big activity is the...
