An engating lesson plan relates mass and volume to better understand density. Young scientists explore and experiment with floating and sinking as well as density cubes. Then, they solve how to make a sinking item float.

Turn your pupils into engineers who are able to use scientific principals to design a ship. This long-term project expects pupils to understand concepts of density, buoyancy, displacement, and metacenter, and apply them to constructing a...

How does chemistry help deep-sea explorers? Part four of a five-part series of lessons from aboard the Okeanos Explorer introduces middle school scientists to technologies used in ocean exploration. Groups work together to analyze data...

Ninth graders predict when an object will sink or float based on comparison of the density of the object to the density of the substance in which it is placed.

Science learners simulate what happens when ice breaks up and floats on water and how increased pressure on ice causes it to melt faster. They view a clip from the movie, The Day After Tomorrow, and relate their lab activities to what...

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...

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.

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.

Note that this lesson is best paired with the preceding lesson in the unit. In that lesson, elementary physical scientists observed that the color coating of M&Ms® candies do not mix when dissolved off of the chocolate surface. Now...

Students analyze the relationship between density, buoyancy, and salinity. In this chemical properties lesson, students read a background activity for the lesson and experiments to the topics. Students discuss the questions and complete...

Fourth graders calculate density, compare densities of solids and liquids, measure liquids using a balance, and investigate the significance of density. They conduct an experiment to determine an order of densities, and complete a...

Fifth graders determine volume and density through their knowledge of mass, volume and density.

Young scholars hypothesize and observe what occurs when raisins are dropped in a carbonated liquid. They examine buoyancy and how density effects ascent and descent.

Students analyze population data. They convert population data into simple density maps to help make decisions about their world. They select the best location for a school store based on population density. They present their maps...

Tenth graders experiment with floating and sinking objects and heavy and light liquids, using correct terms, like density, to explain what happens.  In this Hindenburg lesson, 10th graders watch a demonstration called the invisible...

Pupils explore physics by conducting a class experiment. For this density lesson, students examine a list of items and discuss whether they will sink or float and then determine their density. Pupils examine the objects over five days...

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.

Students explore density by floating golf balls. They explore having their golf balls float halfway in a container of water and discuss density and its realtionship to where the golf balls are floating. After adding food coloring, they...

Learners analyze density. In this density lesson, students experiment with floating an egg. Learners discover that salt added to water changes the density of the water allowing an egg to float.

Students observe earth science by examining results from an experiment. In this buoyancy lesson, students practice floating different items in two different liquids and identify why certain objects will float and others sink. Students...

Learners examine the relationship between density and buoyancy.  In this physics lesson students use Archimedes' Principle to complete calculations on buoyancy and a lab activity.

Sixth graders find the physical properties of matter. In this matter lesson, 6th graders measure mass, volume, and density. Students are broken into 3 tiers with 3 different activities based on their understanding of mass and volume. 

Students collect data and make observations on how given element samples respond to the field of a magnet and they calculate the density of the samples by finding the mass and volume.

Students compares the density and distribution differences of four species of spiders in two hypothetical habitats. They "sample" two habitats and then do calculations such as average density and relative distributions to compare the...
