Students use density to identify what metal a gold colored weight is made of. They use a spreadsheet to graph the experimental density of common metals and compare the know densities to their calculated density of the known metal.

Students observe 2 demonstrations of density. In this density lesson plan, students observe a vial with various substances of different densities. Students then observe the differences between a diet coke and a regular coke can when on a...

Students discover the different forms of water on Earth. In this states of water lesson, students read material on the different forms of water and how they are created. The students answer written questions on worksheets.

Students study the water cycle and how the sun is an important factor.  In this water cycle lesson students investigate how to desalinate water and explore the different densities of fresh versus saltwater.

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...

Students experiment with water density, temperature and salinity. In this water lesson, students observe how the coldest water sinks to the bottom of a test tube, and how saltwater sinks in comparison to freshwater.

Students experiment floating a variety of objects in various liquids. They discover how density affects the ability of an object to float and apply the concept of density to solve problems.

Young scholars use a balance and weigh a rock sample. They weigh the rock suspended on a sling in a glass of water. They tabulate the rock's density using the two weights and compare the density of various rocks of similar sizes.

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...

Students develop their own techniques for drawing a small sample of solutions into a straw. They hypothesize ways to increase the density of water, and discuss how salt-free rainwater tends to float on top of salty seawater.

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

Use the classic density demonstration of placing a cola, a clear soda, and a diet soda into a tank of water. Then let learners attempt to pour some of the soda into layers in a clear container. The procedure explains a thermocline, and...

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.

Clay's as good a material as any to build a boat, right? An introductory activity sets the stage for two activities associated with buoyancy. The first involves building boats out of clay, while the second uses these boats to measure the...

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...

Fifth graders apply the concepts they know regarding mass, volume and density in the previous activities to design a boat. Student teams must make a boat which can travel the waters of the Amazon Rainforest. Each group makes a...

Students design and execute a lab through which they study the distinctions between density, buoyancy, and volume.

Students calculate the volume of a specific mass of water placed in selected pieces of common laboratory glassware, using the density formula. They then determine the accuracy of the volumetric measurement for selected pieces of...

Use this art lesson to study insolubility and density. Combining water-based paint and mineral oil will cause a fun and interactive painting. This is a great art project to incorporate during a science unit.

Students experiment with the visocosity of corn syrup, mineral oil, vegetable oil, water, and honey. They research viscosity before beginning. Pupils draw the conclusion that the marble sinks more slowly in the liquids with greater...

Have your class explore density and buoyancy using this resource. Learners read the book Who Sank the Boat, and use several items, such as rubber balls, bottle caps, wood, and other household items to conduct an experiment. Using a tub...

Junior chemists manufacture biodiesel in the lab. In this exercise, they check the purity of the biodiesel using thin layer chromatography. They also calculate its density and heat of combustion. They are sure to rise to the...

Students examine how salt water is more dense than fresh water. They discuss how manatees need to float and sink, conduct a sink or float experiment, and conduct an experiment with eggs and salt and fresh water.

Build an air lift siphon using your mad physics skills! Learners first investigate the importance of circulating water in aquaponics systems. They then use density to their advantage as they engineer an air lift siphon
