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

Freshwater/Saltwater "Eggs-Periment"
Young scholars explore water properties by conducting a class experiment. In this buoyancy lesson, students utilize freshwater, saltwater, plastic cups, hard boiled eggs and food coloring to experiment with the floating capabilities of...
Curated OER
"Eggs-perimenting" Fun
Young scholars 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...

Buoyant Behavior
Combine science and literature with this lesson 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 how an egg...
Curated OER
Density: Floating, Sinking, and Suspending
Students observe teacher demonstrations that illustrate density. In this density lesson, 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 floats in salt...
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.
