Students examine the effects of temperature and density in ocean currents. In this density lesson, students explain how coastal climates are impacted by ocean currents. They investigate how the ocean currents are affected by temperature...

Young scholars 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.

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...

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

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

Students 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 students construct a hydrometer and create a liquid density column. 

High schoolers 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 plan, students use interactive whiteboards to review definitions regarding density and compare the density of selected objects.

Students 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."

Learners 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 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 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 having...

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

Learners 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...

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

Have your class predict whether objects will sink or float in water. Learners consider a data table of mass, volume and whether the object sank or floated. They develop an evidence-based explanation for the results.

This open-ended boat building exercise is meant to be part of a three-instructional activity series on ships. Links to the other two lessons are included. This particular part is mostly a group lab activity in which they build a boat,...

There are three separate lessons within this resource that can be used together, or that can each stand alone. In the first, five simple activities allow junior scientists to examine the amazing properties of water. In the second, they...
