Why Do Some Things Float?
Students recognize that density determines whether objects sink or float. In this sink or float lesson, students experiment with plastic in three liquids. students drop their objects into the liquids and observe and record their results.

What Is Viscosity?
Students experiment with the visocosity of corn syrup, mineral oil, vegetable oil, water, and honey. They research viscosity before beginning. Pupils draw the conclusion that the marble sinks more slowly in the liquids with greater...

Sink or Float
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.

Observation Milk Fat Lesson
Turn your class loose to experiment with the different fat content in skim milk, whole milk, half and half, and heavy cream. This is a visually vibrant experiment, as learners drip food coloring on the surface of the products and measure...

Science: Different Levels of Density
Students 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 each...
Curated OER
Density
Second graders watch a demonstration and complete an experiment to determine how an objects' density allows it to float or sink. They work in small groups to assimilate the characteristics of items that float as opposed to simply...
Curated OER
Density
In this density learning exercise, students read a selection on density and answer 10 questions using the information from the selection.

The Role of Density in Sinking or Floating: Relational Causality
High schoolers consider density and how it affects sinking and floating. Students make predictions, test liquids, and observe why some liquids sink and others float. They perform experiments to determine relational causality and how...
Curated OER
Defining Density as a Relationship
Students investigate density and its relationship to air and gas. Students perform experiments to determine if gases have mass. They explore possible ways to figure out the density of gases.
Curated OER
Deducing Density
In this deducing density learning exercise, students follow the procedures to set up an experiment about objects floating in water and liquids of different densities, answer questions, collect data and complete charts.
Curated OER
Density Lab Activities
Young scholars participate in several density lab activities in order to clarify the misconceptions that solids sink and liquids float. Students work with triple beam balances to find mass of objects to calculate density.
Curated OER
Density In A Wave Machine
Students explore density. In this science lesson plan, students gain an understanding of the concept of density, especially as it relates to liquid. Students demonstrate that a less dense liquid will float on a denser liquid and that...
Curated OER
Density and Mass
Students experiment to find which liquids are more dense. In this density and mass lesson plan, students predict and then test objects to observe and measure their density. students observe which items sink and float. Students complete...
Curated OER
Density
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.
