Density Balloon
Learners experiment with density using a mylar balloon and hair dryer in an experimental setting. The concept of density is often confusing to students and this activity gives them an introductory insight into the concept in a fun way.
Curated OER
Floating Pencil
Students discover how salt water makes a pencil float better than freshwater by measuring and comparing the lengths of the portion of the pencil that floats above the water surface. They then determine if an unknown water sample is...
Curated OER
Rising Waters
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.
Curated OER
Displaying Data
Students create a display map with data from a previous lesson. They incorporate graduated marks that identify areas of the school grounds that are good for planting based on density.
Curated OER
Earth: The Water Planet
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.
Curated OER
Density - To Float or Not to Float? That is the Question!
Students investigate how to find the density of fluids and solids using math. Students also learn how to find the density of regular and irregular shaped objects.
Curated OER
Diving Raisins
Students hypothesize and observe what occurs when raisins are dropped in a carbonated liquid. They examine buoyancy and how density effects ascent and descent.
Curated OER
More Volume Please! Don't Be Dense!
Fifth graders determine volume and density through their knowledge of mass, volume and density.
Curated OER
Density Destiny
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.
Curated OER
Mass, Volume and Density
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.
Curated OER
Using Soap Foam to Alter the Density of Plaster of Paris
Students determine the density of Plaster of Paris that has been prepared with a foam generated from dishwashing liquids and shampoo.
Curated OER
Testing Density of Various Soap Products
Young scholars have the opportunity to observe, measure and analyze the density of aerosol shaving creams and foams generated from shampoo and dishwashing liquids or detergents.
Curated OER
How Does Altitude Relate To Density?
Students demonstrate an understanding of the properties of matter by applying them to density, pressure, and temperature. The educational software program, "Foilsim" is used in this inquiry.
Curated OER
Density Discoveries
Students participate in Density Discoveries, which is a hands-on learning opportunity for students to find the mass, volume, and density of solid matter.
Curated OER
Can You Find the Difference?
Students create their own balance to determine a difference in the weight (and composition) of cents made in different years.
Curated OER
Float Your Boat
Students design an experiment to find density using Archimedes' Principle. In this physics lesson, students calculate density using mass and volume. They share their findings in class.
Curated OER
i-Density Crisis
Eighth graders determine the density using mass and volume. For this science lesson, 8th graders explain why some materials float or sink. They estimate the density of objects based on whether it floats or sinks in a liquid of known...
Curated OER
Introduction to Density
Seventh graders define density in their own words. In this physics lesson, 7th graders solve density problems using its mathematical formula. They explain why some objects flow and some sink.
Curated OER
To Float or Not to Float - A Lesson on Density
Learners define density in their own words. In this physics lesson, students calculate density using mass and volume. They explain why some objects sink and some float.
Curated OER
Density, Iron, and Anemia
Young scholars explain what factors determine density. In this physics lesson, students hypothesize which objects are less dense. They cite the importance of density in everyday life.
Curated OER
Condiment Diver: The World's Simplest Cartesian Diver
Middle schoolers explain what density is in their own words. In this physics lesson, students perform the condiment experiment and explain why some float and some sink. They share their findings in class.
Curated OER
The Floating Golf Ball
Fourth graders discuss density. In this floating golf ball lesson students complete a lab activity on density while working in groups.
Curated OER
Wood Identification Based on Density
Eighth graders measure irregular and regular shaped solids. In this investigative lesson students calculator volume, mass and density of wood and blocks.
Curated OER
Diving Raisins
Students participate in a mini lab to explore density. For this density lesson students view a demonstration and answer questions.
