salinity of water and density experiment

Evan is back with another impressive water experiment that you can try at home to learn about water salinity and density. Fresh water is less dense than salt water, so it can sit on top. In undistributed waters, they can remain as separate bodies for a long time! This is referred to as a salt wedge. Did you know there is a pretty amazing salt ...

Design the experiment by preparing several solutions with varying amounts of salt dissolved in water (variables), then placing an egg in each solution and observing whether it floats or sinks. Collect and record data on the egg’s buoyancy in each solution, noting the specific salt concentrations.

Salt Water Density Experiment. Here's a brightly colored science experiment that not only looks cool, but allows students to develop their own understanding of density! I used this experiment for a freshman Physical Science class, but it could be adapted for many ages and situations.

We experimented with the salinity of water and how it affects items sinking or floating. We did this on the density of water based on its salt content by using fresh water, and also water with the approximate salt content in the ocean, the Great Salt Lake, the Dead Sea (bordering Israel and Jordan).

Evan is back with another impressive water #scienceexperiment that you can try at home to learn about water salinity and density. 💦Fresh water is less dense...

This super easy salt water experiment is the perfect kitchen science experiment to teach kids about the density of salt versus fresh water. With summer approaching and beach trips planned it’s a great time to learn about how salty ocean water is different from fresh river water.

If you add salt to plain water, it increases the density of the water. In fact, if you add enough salt, you can make the water so dense that an egg will actually float in it! Explore how this works in this science activity.

This video shows the different densities of freshwater and saltwater. Saltwater is denser and sinks down in the freshwater jar, and will only mix with the freshwater after some time. The cold freshwater will stay on the top layer in saltwater.

When you placed the egg into the tap water, the egg sank because it was denser than the water. But when you placed an egg into the saltwater, it floated: The saltwater was denser than the egg. By trying the experiment with different materials, you will be testing the density of different objects.

This experiment uses simple kitchen items to mesmerize your students. We use this Salt Water Density Experiment while investigating our Earth’s Water Unit since it is an effective at displaying the difference in density between salt and fresh water.
