Students comprehend the four parameters of water quality. They perform tests for salinity, dissolved oxygen, pH and clarity or turbidity. Students comprehend why scientists and environmental managers monitor water uality and aquatic...

For this activity, students investigate whether objects and liquids float or sink when placed in water. As they proceed, they will develop an understanding of what density is. Student handouts are provided.

Because different liquids have different properties, density also differs. In this lesson from the Illinois Institute of Technology, students will calculate densities of water, dish-washing detergent, cooking oil, and other liquids.

Students determine whether a liquid will sink or float in water by comparing its density to the density of water.

After students conduct the two associated activities, Density Column Lab - Parts 1 and 2, present this lesson to provide them with an understanding of why the density column's oil, water and syrup layers do not mix and how the concepts...

Students experiment with liquids; comparing and contrasting, and creating a density tower leading to a beginning understanding of density.

Students explore the concept of density by investigating how several solids and liquids interact. Through hands-on activities and a teacher demonstration, they develop a greater understanding of density by using their observational...

Students first predict, then mix several liquids and then add salt to the mix, simulating a lava lamp.

This lab experiment has students observe and compare the density of five different liquids while measuring mass and volume.

An easy to do activity that investigates density and solubility. The activity is presented in lesson plan format that meets NSES standards.

Middle schoolers investigate density in this activity when they try to find out if oil or water has a higher density.

An experiment in density. After a review of floating and sinking of different materials, students test four bottles, all holding four ounces of water, to see if they will float or sink. They each contain a different density of sugar...

For this inquiry lab activity, students will attempt to layer 6 different kinds of soda pops in a large test tube using their knowledge of density and other physical properties of liquids.

Students investigate the properties of water in the ice and liquid phase as it relates to convection in the ocean and density driven circulation, and ultimately the climate.

This lesson introduces students to the important concept of density. The focus is on the more easily understood densities of solids, but students can also explore the densities of liquids and gases. Students devise methods to determine...

Learners use the water-displacement method to find the volume of different rods that all have the same mass.

How does oil seep naturally from beneath layers of rock to the surface of the ocean?
