How to Float an Egg
Use the scientific method to experiment with an egg. Your class can examine buoyancy and density by finding how many spoons of salt are needed to float an egg. They can predict, experiment, record data, and analyze results.

Carbon Dioxide - Sources and Sinks
Where does all of the carbon dioxide come from that is supposedly leading to climate change? Earth science pupils test animal, plant, and fossil fuels as sources in this investigation. Using an indicator, BTB, they are able to detect the...
Curated OER
Sink or Float
Third graders sort objects into those they think will float and those that will sink and test their predictions. They experiment with clay molding it into shapes that float. They place pennies in them until they sink. They test other...

Float or Sink?
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...
Curated OER
Sink or Float
Students explore water properties by conducting a class experiment. In this buoyancy lesson, students make predictions as to whether or not specific objects will sink or float in water. Students conduct the experiment and record their...
Curated OER
Sink or Float
Students experiment with different objects to test if they sink or float. They predict what the object will do before it is put into the water. They are allowed to play with the items after the experiment is over.
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...

Heavy Ice: Day Five
Students explore physics by conducting a class experiment. In this density lesson plan, students examine a list of items and discuss whether they will sink or float and then determine their density. Students examine the objects over five...

Vegetable Olympic Swimming: Will it Float?
Students inspect nutrition by conducting a science experiment in class. In this vegetable identification lesson, students examine a group of different veggies and predict whether they will sink or float in a tub of water. Students check...

The Role of Density in Sinking or Floating: Relational Causality
Students watch the teacher do a demonstration of density with diet and regular soda. Note: try this first, as different types of artificial sweetener have different densities. Students discuss density and volume. They discuss "Relational...

Will the Pumpkin Sink or Float?
Students participate in a sink or float activity using pumpkins.
Curated OER
Sink or Float?
Students analyze the relationship between density, buoyancy, and salinity. In this chemical properties instructional activity, students read a background activity for the instructional activity and experiments to the topics. Students...
Curated OER
The Role of Density in Sinking or Floating: Relational Causality
Students 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 liquids...
Curated OER
WHY DO SOME THINGS FLOAT WHILE OTHERS SINK
Students explore how density can cause things to sink or float by experimenting with a jar, oil and corn syrup.
Curated OER
Does Soap Float?
Students form hypotheses and carry out an investigation in order to answer a central question: Does soap float? The focus of this lesson is on scientific inquiry, but it incorporates scientific topics such as sinking and floating.
Curated OER
To Float or Not to Float, That is the Question?
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...

What's The Matter: A Sinker or Floater?
Students conduct an experiment. For this water lesson, students watch the lesson "Float and Sink" on an interactive website. Students learn how to test items in water and then work in groups to test their items. Students discuss their...

Changing Planet: Ocean Acidification - the Chemistry is Less than Basic!
A video and laboratory investigation are highlights to this lesson on acidification of ocean water due to increased atmospheric carbon dioxide. Using bromothymol blue (BTB) as an indicator, pupils analyze the amount of carbon dioxide...
Curated OER
Floating and Sinking
Young scholars conduct experiments in which they investigate which materials float and which sink. They examine what qualities the materials that float have in common. They carry out a scientific investigation, predict, and test their...
