4/7/2023 0 Comments Eggs float or sink![]() Try this experiment again, but instead of using an egg use a potato slice or a carrot slice. By adding enough salt, you increase the density of the water so that it is higher than the density of the egg and the egg will float! Other Ideas to Try ![]() You don’t really change the volume of the water by adding salt. 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’s density is only slightly higher than water at 1.03 g/mL, but that is enough to make the egg sink. The egg will sink in regular tap water because the density of the egg is greater than the density of water. Objects will sink in water if their density is greater than 1 g/mL. Objects will float in water if their density is less than 1 g/mL. Simply said, how much “stuff” in a given volume. Why does the egg sink in regular tap water, but float in saltwater? The answer lies in the density of water!ĭensity is a measure of the mass per unit volume of a substance. Watch the Floating Egg Science Experiment Step by Step Instructions How Does the Floating Egg Science Experiment Work Why do you think one egg sinks and the other egg floats?įind out the answer in the how does this experiment work section below. What happens to the egg? That’s right, it floats. Step 5 – Next carefully place the second egg into the glass with the salt water. What do you think will happen if you place the egg into the glass with the salt water? Write down your hypothesis (prediction) and then test it to see if you were right. Step 3 – Add 3 Tablespoons of salt to the water and stir until it is completely combined. Step 2 – Fill another tall drinking glass about 3/4 full of water. What happens to the egg? That’s right, it sinks to the bottom.ĭid you know there is a way to make it float? Continue on in the experiment to find out how. Step 1 – Fill a tall drinking glass about 3/4 full of water and carefully place the egg into the glass. Do you think that the eggs will sink or float when placed in water? Do you think it’s possible to make them float? If so, how? Write down your hypothesis (prediction) and then follow the steps below. Note that they are both raw eggs and have a similar size and weight. JUMP TO SECTION: Instructions | Video Tutorial | How it Works Supplies Neededįloating Egg SCIENCE EXPERIMENT INSTRUCTIONSĮxperiment Setup – Start with some observations about the eggs. Can you make an egg float in water? In this simple science experiment, we take just a few minutes to test the laws of density and discover just how easy it is to make an egg float!īelow you’ll find detailed instructions and our demonstration video as well as the scientific explanation of “why it works.” We’ve also included a more ideas to explore the concept a bit further. ![]()
