Students experiment with different salinities of water using straws and different colors of water. They collect and interpret data from the experiment.

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...

Learners find the density of two substances. In this density lesson plan, students determine the density of water and ethyl alcohol and compare their densities. They enter their data into the computer to produce a class compiled graph....

Students watch the teacher do a demonstration of density with diet and regular soda. Note: try this first, as different types of artificial sweetener have different densities. Students discuss density and volume. They discuss "Relational...

Young scholars conduct a series of investigations on the unique properties of water. In this general science instructional activity, students explain what causes water's surface tension. They explain the different stages in the water cycle.

Students calculate the densities of several liquids that appear similar.  In this physical science lesson, students go beyond understanding the way liquids of different densities behave to researching how this knowledge applies in...

Students experiment with a variety of liquids to calculate density. In this integrated science and math lesson plan, students listen to a story in which the characters must prove and explain why 5 "mystery" liquids react in a certain...

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

A classic investigation on the density of liquids is explained for you in this lesson plan. Te begin, you prepare water samples of different salinities and then add different food coloring to keep them separated and easily identified....

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....

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 explore the concept of density. In this density lesson plan, students determine the density of a crown and a sample of clay. They hypothesize about the densities of 4 liquids they are given including molasses, cooking oil, a red...

Students investigate density and salinity of water. In this density and salinity lesson plan, students find the density of objects and liquids and show the relationship between the salinity and density of water. Students add salt to...

Students find the mass, volume, and density of various objects. In this density measurement instructional activity, students observe how same-sized objects can have different masses, then use water displacement to find the density of...

Students investigate the concept of density by observing demonstrations. In this density lesson plan, students make observations while the teacher demonstrates the Cartesian diver, a density column, a candle trough, a wave bottle, an...

Sixth graders explore the concept of density as a relationship of an object's mass to its volume. Densities of a variety of objects are compared and used to identify an unknown object.

Students experiment with objects of different densities. In this density lesson, students examine same-sized objects with different weights, then look at a teacher explanation of density. Students make wave bottles and a density jar to...

Students discover the different forms of water on Earth. In this states of water lesson, students read material on the different forms of water and how they are created. The students answer written questions on worksheets.

Learners determine the density of 1 drop of water. In this determining density lesson plan, students determine the mass and volume of a drop of water in the lab using appropriate lab techniques and calculate the density of a drop of water.

Students observe 2 demonstrations of density. In this density lesson plan, students observe a vial with various substances of different densities. Students then observe the differences between a diet coke and a regular coke can when on a...

Students experiment floating a variety of objects in various liquids. They discover how density affects the ability of an object to float and apply the concept of density to solve problems.

Use this art lesson to study insolubility and density. Combining water-based paint and mineral oil will cause a fun and interactive painting. This is a great art project to incorporate during a science unit.

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...

Learners recognize that density determines whether objects sink or float.  In this sink or float lesson, students experiment with plastic in three liquids. learners drop their objects into the liquids and observe and record their...
