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...

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.

Density - An Introduction
Students experiment with objects of different densities. In this density instructional activity, students examine same-sized objects with different weights, then look at a teacher explanation of density. Students make wave bottles and...
Curated OER
Graphical Determination of Density
Students 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 graph.
Curated OER
Regular Coke versus Diet Coke, Which is Denser?
Students investigate the density of liquids. For this geometry lesson, students calculate the volume and differentiate between volume, mass and density. They observe similarity and differences between coke and diet coke.

Serc: Investigating Density in Solutions: How Can You Make an Egg Float?
In this activity, young scholars will learn about density by determining how to make an egg float in water. By the end of the lesson, students will understand that density and weight are different and that density matters in floatation....

Middle School Chemistry: Density: Sink and Float for Liquids
Young scholars 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.

Serc: Density of Solid Objects
In this science inquiry, students 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.

Serc: Mn Step: Sink or Float? Inquiry Investigation
For this activity, students 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'.
HotChalk
Hot Chalk: Lesson Plans Page: Sink or Float?
This lesson plan is designed to have young children explore the concept of sinking vs. floating by using the skills of prediction, observation and classification.

Serc: Water Activity
Students investigate water by estimating how long it takes to freeze, then see if the ice cube will float in water, and eventually work with other items to see if they sink or float in water.
