Floating Egg Experiment Worksheet

You ll need a few things for this egg floating experiment.

Floating egg experiment worksheet. The floating egg experiment is a good example. Probably half the class correctly hypothesized that the egg would float in the salt water but everyone was excited to see it actually happen. We did this experiment as part of our ocean unit.

Fill the two containers with equal amounts of tap water. First heat one jar of water so that it s easier to mix the salt into it. With the use of an egg salt and water kids will learn and understand the concept of floating.

This will save you time but don t let the kids touch the jar when it s hot. Record if the egg floats in a data table. Objects will float in water if their density is less than 1 g ml.

They will learn how and why lighter objects can easily float in water and heavier objects sink to the bottom. Procedure first hypothesize whether or not an egg will float in water and or if an egg will float in saltwater 1. Here s the sheet you can download it below that i use with my class.

When you add salt to the water you are increasing the density of the water by adding more mass or stuff in the given volume. The egg will sink in regular tap water because the density of the egg is greater than the density of water. Develop a hypothesis for which container salt or fresh water will cause the egg to float.

The egg s density is only slightly higher than water at 1 03 g ml but that is enough to make the egg sink. If you live near the ocean you can just use seawater as well for this experiment but it will look dirty. Add salt iodized or non iodized to water and mix solution.
