Directions Fill a clear glass a little over half full of water. Carefully place an egg in the glass. It should lay on the bottom of the glass if it is fresh.

Salt Water Density Science Experiment April 5, by littlebins 13 Comments This easy to set up salt water density science experiment takes the classic sink and float science experiment to a whole new level.

What will happen to the objects in salt water? Will an egg float? There are so many questions to ask and predictions to make with this easy salt water density science activity.

Make sure to check out all our classic science experiments for more great ideas! I mixed and mixed and mixed and had my son mix and mix and mix seemed to need a lot of re-mixing along the way.

It was pretty salt heavy. I got out two eggs as I had read that eggs specifically work great for this experiment. See some of the items we chose below. Test each item by placing one gently in the fresh water measurer.

So explaining salt water density to a preschooler is not the easiest task, but you can show that two things of similar size can weigh different amounts and that is what causes things to sink or float. Things that have a higher density may sink and things with a lower density may float. Ok, so obviously we know that salt makes the water more dense allowing more types of objects float when they might not in fresh water.

Fresh water is less dense so many things sink. As the salt dissolves in the water, it adds mass more weight to the water! This makes the water more dense and thus allows more objects to float on the surface. The best response from my son: I like to let Liam examine and observe as long as he is interested.

Can you guess which one? This is hard for Liam to notice on his own, but by helping him discover it by asking him questions about what he sees, he can now see it too! He can also tell you about it. You know what, it worked. Liam guessed it would sink in both and I was feeling a bit skeptical myself!

I got pictures to prove it! Some I figured would be too light and some too heavy. As he became more familiar with how the salt water worked, he could more easily predict what might float or sink.

My favorite is the super hero!

Floating egg experiment

I filled a mason jar half full of room temp water. I put a tiny amount of water in the second mason jar and mix in more salt. Liam squeezed in some food coloring.Be careful to use fresh eggs however, because the older an egg gets the more air is contained inside the shell, which will make it float.

The “sink or float” experiment is actually how we test to see that our eggs .

Experiment Materials. A few dozen eggs that are in egg cartons (Large-sized eggs work best) Large plastic trash bag ; Scissors ; Bucket . Drop as many eggs into plain tap water as you want, but they'll all sink to the bottom.

In the Floating Egg experiment, we'll show you how the addition of something as simple as table salt, can drastically alter what happens to eggs in water. Earth Science Experiments, Floating Eggs. These Earth Science Experiments use fresh eggs for a fun and easy science activity.

Expertise. Insights. Illumination.

In this experiment you will learn how eggs can actually float in water instead of sinking. After getting your eggs to float you will try floating an egg between fresh and salty water.

So many egg activities for kids all in one place! Egg Decorating, Crafts, Science, Painting and Sculpture, and more. Pendulum Challenge. Make this thing swing back and forth in 5 seconds.
