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 discover density.  In this density lesson, students discover the properties of objects that allow them to float or sink in water.

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 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...

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

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 use scientific measuring tools to collect and use scientific data. They determine the density of four different objects by using their data to explain why objects have similar/different densities even though they are both made...

Students use the scientific method to conduct an experiment and use varied methods to gather background information. They correctly use lab equipment and prepare tables and graphs that organize, conclude, and present their findings. ...

Students observe teacher demonstrations that illustrate density. For 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...

In 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.

Students determine the mass, volume, and density of two different mineral samples. Students show data and calculations as well as answer questions about the mineral identities.

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

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.

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.

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 read and interpret graphs. In this population lesson plan, students explore population and population density as they read several data graphs and respond to questions.

Though information-packed, this presentation on soil is drab if it stands alone. As you journey through slides about soil texture, make sure to pass around samples of each type. Perform demonstrations as you lecture on soil density and...

Compare information from a US population cartogram and a standard US map. Learners draw conclusions about population density by analyzing census data a population distribution. They discover that census data is used to apportion seats in...

Learners collect data from different grade levels at their school and develop thematic maps which show population density, and determine how this might affect the school and themselves in the future.

The first golf balls were made of wood and would only last for a few games. Modern golf balls last a lot longer but they don't float. The presentation provides the directions for a lab to determine the minimum amount of salt needed to...

All soil is not created equal! A lab activity asks learners to collect and analyze soil. Specific calculations determine the amount of sand, silt, and clay in a sample and allow individuals to identify the soil texture. 

How many pennies can an aluminum foil boat hold? That is the challenge in a collaborative activity designed to explore the concept of buoyancy. Learners use aluminum foil to build makeshift boats and test the weight they hold before...

Students 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.

Students explore the concept of density. They use the the formula Density = Mass/Volume, one can determine where certain liquids and objects will settle in a graduated cylinder. In addiiton, they design a process to separate the liquids.
