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...

Begin with an introduction to famous deep-sea submersibles. Learners work in groups to gather information on different vessels and then share with the class. Each group then uses water displacement to help calculate the density of...

Learners determine the density of 1 drop of water. In this determining density lesson plan, students determine the mass and volume of a drop of water in the lab using appropriate lab techniques and calculate the density of a drop of water.

Students find the density of objects by finding their mass and their volume. In this density lesson plan, students determine the mass of objects, the find the volume by using formulas or by water displacement and they calculate the...

Young scholars experiment with a variety of liquids to calculate density. In this integrated science and math lesson plan, students listen to a story in which the characters must prove and explain why 5 "mystery" liquids react in a...

In this moon's density learning exercise, students solve 4 problems about the Moon and a model planet. They find the Moon's density and they find its volume. They make a model of a planet's interior and use its mass and radius to find...

Learners investigate density using film canisters filled with different density materials and larger objects of varying density. In this density lesson plan, students discuss the concept of density and rank film containers from dense to...

In this density learning exercise, students read about density, volume and mass. They then use what they learned to answer the 8 questions on the page. The answers are on the last page.

Students investigate density and salinity of water. In this density and salinity lesson plan, students find the density of objects and liquids and show the relationship between the salinity and density of water. Students add salt to...

In this density of pennies worksheet, student conduct an experiment to determine the metals used in the core of pennies made after 1983. High schoolers design their own experiments using a balance and graph paper to determine the density...

Students explore the concept of density. In this density lesson plan, students determine the density of a crown and a sample of clay. They hypothesize about the densities of 4 liquids they are given including molasses, cooking oil, a red...

A micro-unit on the phase changes of water includes three laboratory activities. Junior scientists compare the densities of ice and water, and then they do the same for cold and warm water. They examine freezing and boiling temperatures....

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...

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...

Why do some things float and others sink? A creative simulation allows learners to adjust mass and volume of an object to affect its buoyancy in water. A graph records the effect of each manipulation.

Atoms, elements, and molecules, oh my! Teaching the fundamentals of chemistry to curious sixth graders has never been easier to accomplish. Here is a resource that pulls together everything needed to get them off to a good start,...

Whatever floats your boat. Young engineers learn about density by measuring the masses and volumes of boxes filled with different materials. Using their knowledge of densities, they hypothesize whether objects with given densities will...

Here is a planet worksheet in which learners read about organic molecules detected through spectral lines of the planet Osiris. They calculate the mass, the volume and the densities of common ingredients for planets including Osiris and...

Middle schoolers investigate the role of temperature and salinity in determining seawater density. They use a Temperature-Salinity Diagram to examine the effects of mixing on density.

Students use materials found at a resource table to design simple devices that will house instruments to take water samples from a tub of water. They design 3 instruments, each varying in density so that one will float, one will hover...

Students recognize that density determines whether objects sink or float.  In this sink or float lesson, students experiment with plastic in three liquids. students drop their objects into the liquids and observe and record their...

Students integrate history and science while discovering how salinity affects the density of water. After a lecture/demo, students work in groups to complete a lab activity that demonstrates how salinity affects the density of water.

In this ideal gas law worksheet, students solve eighteen problems using the ideal gas law to solve for moles of gases, temperature of gases, pressure of gases or volumes of gases.

Students investigate ways to find the density of irregular shaped objects. In this physics lesson, students calculate density using its mass and volume. They explain why some objects float or sink in water.
