In this ocean water and life worksheet, students match the vocabulary term with the correct definition. Also, students answer questions by deciding if the statements are true or false. Finally, students complete concepts maps while using...

Students explore physical science by participating in a class experiment. In this chemistry lesson, students discuss what they predict will happen when cooking oil and water are blended together. Students utilize a plastic bottle,...

Young scholars 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 lesson, students discover the different factors that affect an object's density and buoyancy in water. Students conduct several investigations to further...

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.

In this buoyancy instructional activity, 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...

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 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. 

High schoolers 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...

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 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...

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 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, 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 sink. 

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.

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.

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 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...

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.

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.

For this properties of matter worksheet, students answer 11 questions about the various properties of matter such as density, elasticity, malleability, and how hard or brittle a substance is.
