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.

Sink or Float?
Will it sink or will it float? Learners predict the outcome as they drop random objects into a container of water. Then, they keep track of the results and record the data in a t-chart to draw a final conclusion.

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...

"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...

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.
