Students draw upon their prior knowledge of the density of water and practice writing a hypothesis, making an observation, and analyzing data while watching a density demonstration.

Students have the opportunity to observe, measure and analyze the density of aerosol shaving creams and foams generated from shampoo and dishwashing liquids or detergents.

In this water activity, learners review the properties of water including the density, boiling point, and evaporation. Students define mixture, solute, and solvent. This activity has 22 short answer questions.

In this mass worksheet, students fill in a chart with different items and their volume, whether they float or sink, and their density. Students complete this for 10 items and answer 6 multiple choice mass questions.

Students explore the density of liquids. In this scientific inquiry lesson plan, students discover the density of water, corn syrup, and cooking oil through an experiment. In addition, students will draw and label pictures of the...

Pupils explore the physical properties of density. In this hands-on lesson, students calculate density and distinguish between intensive and extensive properties.

For this density laboratory worksheet, students complete 2 prior knowledge questions, then use the "Density Laboratory Gizmo" to complete several activities, answering short answer questions when finished.

High schoolers investigate why some objects float or sink in water. In this physics lesson plan, students calculate the density of clay ball using a mathematical equation. They write a complete lab report about the experiment.

Middle schoolers determine the density of Plaster of Paris that has been prepared with a foam generated from dishwashing liquids and shampoo.

Learners observe teacher demonstrations that illustrate density. In this density lesson, the teacher demonstrates how air bubbles in a carbonated drink can cause a raisin to float and how an egg sinks in fresh water, but floats in salt...

Students explore a hydrometer.  In this gravity lesson plan students construct a hydrometer and create a liquid density column. 

Students compare and contrast the mass, volume, and density of various objects. They use a triple beam balance, measure and record the volume of a cup of water, and discuss the results.

Students explore the meaning of density. In this density lesson, students use interactive whiteboards to review definitions regarding density and compare the density of selected objects.

Pupils must plan, design, and conduct an experiment that answers the scientific question: "Come up with a question that addresses the factors (variables) of the water and its effect on whether an object floats or sinks."

Students research the impact that human activity had on Pennsylvania's water supply over time. In this water quality lesson plan, students research, discuss, and write about how Pennsylvania's water quality has been affected and what...

Students elicit data on the water cycle, ocean topography, and island formation in this six lesson unit. The ocean floor and the properties of water are examined through a variety of discussions and hands-on experiments.

Students participate in Density Discoveries, which is a hands-on learning opportunity for students to find the mass, volume, and density of solid matter.

Fourth graders rank balls by size from smallest to largest and from lightest to heaviest and then by how much they made the water rise. They then discuss why certain balls make the water rise higher than do other balls.

Sixth graders measure and investigate the densities of several objects. They, in teams, determine the mass and volume of each of the 5 objects and record the measurements in the data table.

Students measure the properties of two different types of soap and wood and calculate their densities. Then they predict whether or not whether or not each object would float or sink in fresh or salt water.

Students engage in a lesson plan that is concerned with the water cycle and different states of matter. They conduct research using a variety of resources in preparation for taking a quiz. Then students take the quiz in correlation to...

Learners investigate the states of matter. In this physics lesson, students use water and ice to demonstrate the characteristics of a solid and liquid. Learners record their observations as the state of the water changes.

Pupils observe what happens to water as it goes from a solid to a liquid.  In this exploratory lesson students gain an understanding for the water cycle while working in groups observing what happens to water as it changes state. 

Students explore the states of matter. In this physical science lesson plan, students observe what happens to water when it freezes and record observations. Students then observe ice when it melts and record observations.
