During a unit on density, pupils ponder whether or not temperature affects this property. By carefully inserting blue cold water and yellow hot water into a room-temperature sample, they will see the answer. Make sure to have done the...

Fourth in a set of several little lessons on density, this one compares the density of fresh and salt water. First by demonstration, and then by a hands-on activity, learners find that adding salt increases the density, as is evidenced...

High schoolers determine the linear equations of the density of water and oil by collecting data on the mass of various volumes of each liquid. They construct scatter plots from the data and use these to write the linear equations for...

Learners will like making a liquid layer cake to investigate the relative densities of various liquids: water, oil, and corn syrup. They will also introduce a few solid materials to find out how their densities compare. Standing alone,...

Young scholars find the density of diet soda and regular soda. In this density lesson plan, students measure the mass of a graduated cylinder with 10 different volumes of each soda. They find the mass of the liquid alone and use the...

A fascinating and engaging lesson on the properties of water awaits you. In it, learners engage in four activities that are designed to teach about the properties of water. This exciting plan has worksheets embedded in it which make the...

There's a lot content packed into the four lessons of this physical science unit on density. From salad dressing to the water cycle and hot air balloons, these lessons engage students in hands-on activities that explore real-world...

Given a variety of rocks, junior geologists calculate densities and correlate them to Earth's layers. As a simulation of continental crust, they experiment with how materials of differing density float in water. Finally, they...

Sprouting scientists explore the concept of density by making mass and volume measurements for five different liquids. From these measurements, they calculate densities. They apply their learning to explain Galileo's thermometer works...

Students develop their own techniques for drawing a small sample of solutions into a straw. They hypothesize ways to increase the density of water, and discuss how salt-free rainwater tends to float on top of salty seawater.

High schoolers explore displacement. In this displacement and density instructional activity, pupils find the volume of irregular shaped objects. Afterward, they determine the volume of containers. They compute the amount of water...

It's in your destiny to study density! Young scientists conduct an experiment to study the relationship between weight and density. They compare weights of liquid samples of different substances and predict how their densities are...

Students work in groups to compare the density of different liquids.  In this density lesson, students use cooking oil, liquid detergent and water to measure density.  Students record their results and check the accuracy of...

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

Groups suspend objects within layers of liquids to determine the densities of different liquids and compare them to the densities of objects calculated in Part 1. The groups then carefully test their calculations by layering the...

Students 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...

Learners 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.

Young scholars calculate the densities of several liquids that appear similar.  In this physical science activity, students go beyond understanding the way liquids of different densities behave to researching how this knowledge...

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

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....

Pupils 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. Pupils...

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

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...
