Students explore the density of soap. In this science instructional activity, students conduct an experiment to find which types of soap will float. Students make a hypothesis and record their observations.

Students explore plant biology by conducting field experiments outside of class. In this desert plant lesson, students discuss how cacti thrive in such dry climates and how dense their populations are. Students utilize action cards, a...

Students study how hot air balloons were created and the different types there are.  In this density and lift lesson students build their own hot air balloon.

Students, in groups, stake out and rope off their study area, do population counts and density studies. They construct a map of the whole area, collect plants and insects, and mount and identify the organisms using keys.

Teach the masses about the metric system with this hands-on measurement lesson. Given a fruit or vegetable, learners estimate, measure, and convert its mass using the metric units gram and kilogram.

In this assessment task, learners determine whether a crown with given information is composed of pure gold. The task expects algebraic and numerical solution methods, so unlike Archimedes, no bathtub is necessary.

In this exponential growth worksheet, students determine the population of a country. They set up an integral which represents the mass of an abject and determined the total accumulation of snow in a region. This one-page worksheet...

Students define density and explain how to determine the density of an object. Students participate in a demonstration that shows the differences in the densities of different liquids and how they affect the liquid's physical properties.

Learners explore how density can cause things to sink or float by experimenting with a jar, oil and corn syrup.

Students develop a population density visualization chart to begin the instructional activity. In groups, they use this information to compare to rates of carbon emissions for their country. They identify solutions to the problem and...

Students experiment with density of ice, and examine how density affects how icebergs float in water.

Students measure volume using water displacement and mass using a balance. Once they have calculated these two values they will then calculate density while at the same time working on long division. After the activity and explanation of...

Students perform experiment in which they model convection as it occurs in our Sun. They also explain that convection acts where the effect of gravity and heat are present (low density fluids can rise and cool, and high density fluids...

Fourth graders, in groups, experiment with density and the displacement of water by creating and designing their own boats and seeing which boat holds the most centimeter cubes without sinking..

Students discover the origin of the Great Ocean Conveyor. They participate in a demonstration showing how salinity and temperature affect water density. They also examine the new sea ice that forms every winter.

Young scholars research the development and implementation of a research vessel/vehicle used for deep ocean exploration. For this oceanography lesson, students calculate the density of objects by determining the mass and volume.

Students participate in a demonstration to test the different densities of plastics, and suggest a method that plastic waste can be separated and collected.

Twelfth graders work in teams to design a method of recycled plastics purification by flotation. They base their design on the concept that different kinds of plastics have different densities and keep overall costs and purification time...

Students determine how to use a quarter meter quadrant to find population density, relative density, frequency and how to calculate a diversity index while participating in a virtual field trip. They study how to establish a Correlation...

Students explore various methods for visualizing the results of hydrogen wave function. They observe trends using a polar plot tool and make plots for the first three energy levels of the radial wave function for hydrogen. Students apply...

Young scholars perform experiments to explore differences in wind speed and forest density. Through experimentation and observation, students realize that changes in vegetation affect the atmosphere and wind conditions. They create a...

Fourth graders see that salt increases the density of water and creates a condition wherein objects are more buoyant than would be expected under normal conditions. They describe the relationship between heat energy, evaporation and...

Eighth graders measure strike and dip of given land features and explain the difference between them. They also look at rock and mineral samples for indentification, along with calculating the density. Finally, information is analyzed...

Students determine the density of touch receptors in various parts of the body on the right hand side. They use collected data to draw a picture of the "homunculus" of an experimental subject.
