Experiment with mass and density as scholars figure out what makes things float or sink. First, they watch a podcast introducing these concepts. Be sure to use the comprehension question to test their understanding. Young scientists...

Using a variety of objects, learners conduct buoyancy experiments. They make predictions on which object will sink or float and test their predictions. They use a graphic organizer to record their findings.

Learners investigate which objects sink and which ones float. Learners engage in an experiment, make predictions, and record results on a graphic organizer. This is a comprehensive and easy to follow resource.

Why does a seastar sink, but a jellyfish float? Through a fun investigation, learners examine the concept of buoyancy using simple household items. The challenge: create neutral buoyancy for an action figure in water. With ample...

Swimmers know to float by turning their bodies horizontally rather than vertically, but why does that make a difference? In an interesting lesson, scholars explore buoyancy and the properties of air and water. They test cups to see which...

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.

Ninth graders develop operational definition of density, do computations using density equation, categorize pieces of matter as being able to float on water or not, based on density, explain why some objects sink or float based on...

How is it possible for ocean water to have layers? The sixth installment of a 23-part NOAA Enrichment in Marine sciences and Oceanography (NEMO) program investigates factors that cause different water densities to occur. Experiments...

How do astronauts know how to live and work in a weightless environment? It doesn't come naturally! Junior physicists conduct experiments to examine the link between buoyancy and microgravity. Each activity illustrates a different aspect...

The density of the huge planet of Saturn is 0.7 g/cm3, which means it could float in water! In the second part of 22, science pupils explore the size and order of the planets. They then calculate weight and/or gravity and density of...

Students examine population density in Jewish ghettos. In this Holocaust lesson, students calculate population density of cities around the world using the provided information. Students then discuss the implications of high...

Eighth graders measure irregular and regular shaped solids.  In this investigative lesson plan students calculator volume, mass and density of wood and blocks.

High schoolers determine the density and thickness of a piece of aluminum foil. In this density and thickness of materials lesson plan, students experimentally find the density of a piece of aluminum foil and compare it to the...

Students investigate Archimedes' Principle and show how it relates to density. In this Archimedes' Principle lesson plan, students experiment with a beaker of water, a Styrofoam "boat" and a weight. They predict what will happen when the...

High schoolers calculate the size of a molecule. In this molecules and their sizes lesson plan, students find the size of an oleic acid molecule by using a measured amount of drops of oleic acid to find the volume of the sample, the...

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

Young scholars observe experiments in density and describe the results. In the experiment, milk, corn syrup, and oil are added in different orders to three glasses, while one other glass contains only water. As objects are dropped into...

Learn about defensible space and renewable resources with a lesson about forest fires. After exploring the ways that humans have impacted the environment, kids conduct mock interviews about differing points of view in the conservation...

Students plot the Kaibab deer population from 1905 to 1939 and analyze the changes over time. In this populations lesson plan, students investigate the causes of changing populations of the Kaibab deer and they find the carrying capacity...

Third graders explore the food industry by viewing a presentation about farming. In this farming geography lesson, 3rd graders view globes and maps while identifying the prime geographical locations for fertile land. Students view a...

Students identify different woods based on their density. In this density lesson, students use a triple beam balance to find the mass and a metric ruler for the volume. They look through various wood blocks and identify what type of wood...

Students compare the densities of different liquids. In this liquids lesson plan, students compare color, viscosity, weight, volume, and graph their findings.

Students explore the properties of water. In this cross curriculum art and physical science lesson, students experiment with a variety of materials to demonstrate the cohesive forces and adhesion of water. Students create a water color...

Students explore the meaning of density. In this density lesson, students use interactive whiteboards to review definitions regarding density and compare the density of selected objects.
