Students describe the role of density in driving deep ocean currents and the density layers of the ocean. They determine that the ocean is one continuous body of water with global currents that interact, with water surrounding all...

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.

Students explore the concept of density and buoyancy. In this physics instructional activity, students discover the different factors that affect an object's density and buoyancy in water. Students conduct several investigations to...

Young scholars create a model estuary. In this modeling estuaries lesson, students identify characteristics and mix water of varying densities. Young scholars form a hypothesis, conduct an experiment, and analyze the results.

In this buoyancy worksheet, students read about the principles behind objects floating including density, buoyancy and Archimedes' Principle. Students complete a buoyancy lab where they use a balloon and water and a film canister and...

Students explore the changing density of water. In this physics instructional activity, students investigate how an object's density determines whether it will float or sink in water. They explain why this unique property of is important...

Students explore how fish are able to move easily from one depth to another in water.  In this fish lesson students create their own balloon fish. 

In this density worksheet, students investigate what will happen when various liquids with different densities are put into the same container. They hypothesis and make observations. Students answer 4 questions about their investigation...

Students examine what happens to salt water when it freezes. In groups, they measure density and salt concentrations in different samples of water and record its freezing time. They discuss the relationship between water density and...

Third graders conduct an experiment. In this floating and sinking liquids lesson, 3rd graders discuss density and investigate it using syrup, vegetable oil and colored water. Students observe the results and complete a worksheet.

Students investigate Archimedes' Principle and show how it relates to density. In this Archimedes' Principle lesson plan, students experiment with a beaker of water, a Styrofoam "boat" and a weight. They predict what will happen when the...

Ninth graders develop operational definition of density, do computations using density equation, categorize pieces of matter as being able to float on water or not, based on density, explain why some objects sink or float based on...

Middle schoolers determine density and hardness of wood samples based on several investigations. In this physical science and music lesson, students visit four centers and perform tests on wood samples to determine densities and...

Students collect snow samples around their school. They explore the concepts of density and phase change as well as the math skills of measurement and statistics. Students explore the water cycle through an interactive, down loadable...

Students explore sinking and floating.  In this buoyancy lesson plan, students conduct an investigation dealing with regular and diet soda. Students drop various soda cans into water and then discuss why some float and some...

Students examine how a hot air balloon works. For this hot air balloon lesson, students do an experiment to test the effects of heat on density. Students make their own hot air balloon and act out how nitrogen moves when turned to a liquid.

Young scholars construct their own submarine following a certain procedure. In this physics lesson, students calculate the density of objects using a mathematical formula. They explain why some object floats in water while some do not.

Students investigate the properties of matter. In this properties of matter lesson, students observe containers of different metals and discuss their properties including density. Students find the density of an unknown metal and of...

Students calculate the size of a molecule. In this molecules and their sizes lesson plan, students find the size of an oleic acid molecule by using a measured amount of drops of oleic acid to find the volume of the sample, the thickness...

Students are introduced to the periodic table of elements. They devise and perform and experiment in which they determine the density of specific elements. They use their results to predict the density of other elements in the same group.

Students role play as paleontologists who make inferences about the weight of dinosaurs. They use models and the density of water to make these inferences.

In this properties of matter learning exercise, learners answer 11 questions about the various properties of matter such as density, elasticity, malleability, and how hard or brittle a substance is.

In this calculations worksheet, students find significant figures in numbers, they determine densities of substances and objects, they convert from one metric unit to another and they determine the appropriate unit of measurement for...

For this calculations review worksheet, students convert from one metric unit to another, they identify significant figures in numbers, they find density of substances, and they solve problems using dimensional analysis.
