Regular Coke vs. Diet Coke: Which is Denser?
Learners define the terms "mass," "volume," and "density." The relationship between these three terms is established. They observe the differences between Regular and Diet Coke. They develop an hypotheses about why a can of Regular Coke...
Curated OER
Sink or Float Experiment
Students participate in an experiment to determine which objects float or sink. They use different amounts of salt for the objects and discover as the salt content increases, objects will float. They record their predictions and what...

MEASURING THE DENSITY OF WATER
Students perform an experiment to measure the density of tap water vs. salt water.
Curated OER
Density Demonstration: Coke vs. Diet Coke
In this density demonstration, students compare a can of diet coke to a can of regular coke. They list the similarities and differences of each prior to the demonstration. The cans are placed in a tank of water and students record their...

Density - An Introduction
Young scholars experiment with objects of different densities. For this density lesson, students examine same-sized objects with different weights, then look at a teacher explanation of density. Young scholars make wave bottles and a...
Curated OER
Graphical Determination of Density
Young scholars determine the density of metal shot by a graphical method using significant digits in making measurements and calculations. Students graph a seris of laboratory measurements and determine density from a mass verses volume...
Curated OER
Regular Coke versus Diet Coke, Which is Denser?
Students investigate the density of liquids. In this geometry lesson, students calculate the volume and differentiate between volume, mass and density. They observe similarity and differences between coke and diet coke.
Curated OER
8th Grade Earth Science: Density
Students 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.

Science Is Fun: Bowling Balls Float or Sink?
In this experiment, you test whether two different bowling balls will float or sink, then determine the density of each of the balls to see if they are less than that of water.
Better Lesson
Better Lesson: Floating and Sinking Sorting in Science
Students sort objects according to whether they sink or float.

Uen: Does Coke Float?
Sixth graders predict if different types of coke will float or sink.
Science Education Resource Center at Carleton College
Serc: Mn Step: Sink or Float: All Liquids Do Not Have the Same Density
An experiment in density. After a review of floating and sinking of different materials, students test four bottles, all holding four ounces of water, to see if they will float or sink. They each contain a different density of sugar...

Serc: Investigating Density in Solutions: How Can You Make an Egg Float?
In this activity, students will learn about density by determining how to make an egg float in water. By the end of the instructional activity, students will understand that density and weight are different and that density matters in...
American Chemical Society
Middle School Chemistry: Density: Sink and Float for Liquids
Students determine whether a liquid will sink or float in water by comparing its density to the density of water.
Science and Mathematics Initiative for Learning Enhancement (SMILE)
Smile: Density in Relation to Float and Sink
Students find the densities of objects based on sinking or floating in this activity that demonstrates Archimedes Principle.
Science Education Resource Center at Carleton College
Serc: Density of Solid Objects
In this science inquiry, learners investigate whether volume or density of objects determine the floating or sinking in water. Using a rock and a block of wood teachers engage students in the discussion of density, mass and volume.
Other
National Engineers Week Foundation: Flinker
Students investigate with common objects to see if they can make something that neither floats nor sinks, but rather "flinks" in the middle.

Science Is Fun: Sinking and Floating Soda Cans
An experiment to determine if either a regular or a diet can of soda will float or sink when placed in water, and what causes this.
Science Education Resource Center at Carleton College
Serc: Mn Step: Sink or Float? Inquiry Investigation
For this activity, learners make predictions about whether different objects float or sink, then test them. They are asked to record their observations and results for each, and compare their results to others'.
Middle School Science
Mss: Density Demonstration: Coke vs. Diet Coke
In this demonstration, students will brainstorm to find a solution as to why Diet Coke floats and Coke sinks. Through this exercise students will arrive at a definition of density.
