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.

Will It Sink or Float?
Learners conduct a science experiment to determine whether a variety of objects will sink or float. They discuss the concept of density, and then make predictions about whether the objects will sink or float. They then conduct the...

The Weight of Water
Students examine how salt water is more dense than fresh water. They discuss how manatees need to float and sink, conduct a sink or float experiment, and conduct an experiment with eggs and salt and fresh water.

The Weight of Water
Students examine how salt water is more dense than fresh water through experimentation with eggs.

To Float or Not to Float - Density
Students experiment floating a variety of objects in various liquids. They discover how density affects the ability of an object to float and apply the concept of density to solve problems.

Make An Egg Float!
Young scholars analyze density. In this density lesson plan, students experiment with floating an egg. Young scholars discover that salt added to water changes the density of the water allowing an egg to float.

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...

Freshwater/Saltwater "Eggs-Periment"
Students explore water properties by conducting a class experiment. In this buoyancy instructional activity, students utilize freshwater, saltwater, plastic cups, hard boiled eggs and food coloring to experiment with the floating...
Curated OER
"Eggs-perimenting" Fun
Students dissolve salt into water, place an egg into a glass of salt water, observe and record observations, make a scientific hypothesis, summarize what they studied from this hands-on experiment. They share their ideas and findings...

Buoyant Behavior
Combine science and literature with this instructional activity on buoyancy. Read There's an Ant in Anthony by Bernard Most to examine words containing the letters a, n, and t. Then introduce your class to the word "buoyant." Demonstrate...
Curated OER
Density: Floating, Sinking, and Suspending
Students observe teacher demonstrations that illustrate density. In this density instructional activity, the teacher demonstrates how air bubbles in a carbonated drink can cause a raisin to float and how an egg sinks in fresh water, but...
Curated OER
Salinity
Learners define and discuss salinity, conduct classroom experiment to determine salinity of water sample by using hydrometer, record predictions, and demonstrate understanding of how salinity influences object's ability to float in water.

Biocomplexity Lab Activity: Density and Buoyancy of
Students investigate how the density of water changes the buoyancy of
water. Students create a hypothesis about what will happen when placing the
egg into the water.Students can research online different bodies of water (The Red Sea, The...

Bathtub Physics - Density, Buoyancy and Flotation
Learners study Archimedes' Principle, flotation and the reaction of buoyant forces and explain the relationship between density and flotation.
Curated OER
Learning Lesson: Salt 'n Lighter
Students participate in a demonstration showing that as salinity increases density increases as well. They also examine the different densities of air. They discuss the amount of water displaced by large ships.

Science Lesson #2
Fourth graders explore and experiment with objects that float to see if they float differently in salt water or fresh water. After the experiment, they write a paragraph in their science journal explaining how fresh water and ocean water...
Curated OER
Lesson tow
Students study the ocean and its characteristics. For this oceans lesson students complete a lab activity and are able to predict temperature of certain depths.
