Students use population density and other statistics to compare countries. They find the population density for the countries listed in the table. Students compare findings with a partner, and then share with the class.

Students determine the density and thickness of a piece of aluminum foil. In this density and thickness of materials lesson plan, students experimentally find the density of a piece of aluminum foil and compare it to the theoretical...

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...

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...

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

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.

Learners 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 predict the impact of population density on shelter, transportation, recreation, land use, and social skills and then research that impact on Japan. They write a response about the impact of population density on food...

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

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

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

Students explore the changing density of water. In this physics lesson, 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 to living things.

Students estimate the density of a population of insects (grasshoppers) at a given life cycle stage in a given type of habitat.

Students 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 hardnesses. They...

Students investigate water density. In this water density lesson, students conduct an experiment with food coloring, water and salt to see how the salt effects bodies of water.

Students 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.

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

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...

Students examine how a hot air balloon works. In 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.

Learners discuss the each of the following objects/substances in terms of what contributes to their density: 1) a piece of copper; 2) a piece of bread; 3) steam in the air. They evaluate the causes in the various densities of substances.

Eighth graders measure irregular and regular shaped solids.  In this investigative lesson students calculator volume, mass and density of wood and blocks.

Students practice determining liquid densities in a short, hands-on lab activity. Students use a graduated cylinder to measure out 100 milliliters of a liquid, find its mass using a balance, and record measurements in a data table....

Students consider the causes of density at a microscopic level. They then discover that one cause of density has to do with how many protons and neutrons the material contains.
