This is a great experiment to add to your ocean science lesson plans because the ocean is salty!
If the item still sinks in the saltwater, ask the kids what they think! Should they add more salt? Have each kid contribute an item to the experiment! THE SIMPLE SCIENCE OF DENSITY Small plastic items will work best with the measurements of salt and water provided. We love sink/float style experiments for encouraging predictions! Kids can easily experiment with different objects from around the room. The second egg should float due to the change in density of the water! Mix well to dissolve the salt! Ask the kids what they think will happen this time and demonstrate! STEP 2: In the other glass, fill to the same height with water. Ask the kids what will happen if you carefully drop an egg into the glass of water.

STEP 1: Start by filling one glass about 2/3 of the way full with water. 2 Tall glasses big enough to hold an egg.Looking for easy to print activities, and inexpensive science experiments?Ĭlick below to get your quick and easy science activities.
This salt water experiment asks the question: How does salt affect the density of water? And if you are curious about the rubber egg experiment in the video, click here. Head to the kitchen, open the pantry and be prepared to get a little salty. Let’s get right to investigating what adding salt water to fresh water does with this fun ocean science activity.
