Count Marsili & the Mediterranean Current

Nature provides density columns in the polar regions that provides food for many animals. Young scientists build their own density columns with water in order to answer analysis questions. Through a slideshow presentation, scholars...

In this sixth of seven activities revolving around the concept of density, physical science fans figure out if anything can be done to change the density of an object. Demonstrate by placing a can of regular and a can of diet soda into a...

Get close up and personal with a drop of water to discover how the polarity of its molecules affect its behavior. Elementary hydrologists split and combine water droplets, and also compare them to drops of oil. Much neater than placing a...

Ecology candidates culture pond water organisms over a few days time, then they experiment to find out how increasing nutrients affects the population. As part of a unit on water, this exploration gives your class an understanding of how...

Larvae transportation on the New England seamounts is based on the density of the water. Scholars calculate density and graph salinity versus temperature to better understand the distribution of organisms in a water column....

Learners will like making a liquid layer cake to investigate the relative densities of various liquids: water, oil, and corn syrup. They will also introduce a few solid materials to find out how their densities compare. Standing alone,...

The densities of a variety of liquids are demonstrated in this simple, yet effective experiment. Liquids such as honey, dish soap, cooking oil, water, rubbing alcohol, and corn syrup are put on top of one another in a large beaker,...

Students perform an experiment to measure the density of tap water vs. salt water.

Explore how water interacts with our entire environment through the water cycle. This video employs wonderful models and clear explanations to describe the water cycle. You'll learn about evaporation, condensation, and precipitation, as...

Students find the density of diet soda and regular soda. In this density lesson plan, students measure the mass of a graduated cylinder with 10 different volumes of each soda. They find the mass of the liquid alone and use the volume to...
