If you want to see cool science experiments that are easy to do and learn about density, then you've come to the right place. Density is defined as mass per unit volume, and it is essential to understanding how the world works. These...

This simple density science experiment starts with placing two glasses with yellow water on top of two glasses with blue water. When we remove cards that separate coloured water, colours on the right do not mix, but they do mix quickly...

Here is a cool oil and Ice density experiment! By now, you all know that oil and water don’t mix. But what about when water is frozen? I have been curious about this for a while, so I decided to do an experiment to find out. If you have...

The science will amaze you if you just look close enough to things that surround you. What do you think would happen if you put hot and cold water in one container without mixing? Would "hot-air-balloon" principle work underwater where...

We are observing the different densities of the liquids (coloured water, honey and oil) versus the different densities of the objects (marble, grape, legobrick and foam cube).

Explore the fascinating world of matter in this science experiment video featuring a plastic bottle. Witness how gases, liquids, and solids interact within the confines of a simple plastic container. From dynamic gas expansions to...

Simple density experiments you can try in your kitchen now. We started by putting a glass of water on top of a glass of vegetable oil. That is a cool experiment on its own, but let's focus on density here. After we moved the card that...

Have you ever wondered if an orange would float or sink? It turns out that this is a question that many people ask, and the answer may surprise you. It turns out that not all materials float on water! How does density come into play?...

This lava lamp experiment is a fun and easy experiment every child should try. We haven't done this simple lava lamp experiment for a while, and this time it did not fail to amuse too. We coloured water with food colouring and poured it...

We are back home and we are going back to experiments. A raw egg sinks in water, but can we increase water's density to make it float? Alex adds salt to see what would happen. Then I carefully add fresh water on top of salted one (not to...

This is an impressive but simple experiment for children. We did it with Alex about two years ago, so it was Max's turn now. But this time I added a bit of a twist though. I spread food colouring on the bottom of tea candle, lighted it...

Today, we are making a simple experiment with diving jellyfish in a bottle. It is also called a bottle diver.

You'll have to try this fun kids science experiment to see what happens when you layer liquids of different densities. Making an impressive 8 Layer Density Tower Experiment requires an understanding of density. Let me...

This saltwater density tower experiment will help you and your children understand density better. Density is the mass of a material per unit volume, and it is a fixed number for each material. The density of water is 997 kg/m³;...

Have a snow day any day! You can make it snow no matter how hot it is outside. Be sure to do this project in a tall, clear container so you can see the blizzard you’ve created!

It took some time for us to realize it isn’t the best idea for scientists to experiment on themselves. But along the way, sometimes at the expense of the health of scientists, we have gained crucial insights into their areas of study.

These tiny creatures are Arctic surfclams. They're getting packed up for a trip to the shore. With some help, they're about to take up residence in an intertidal mudflat on the Maine coast, or 'Downeast' as they say...

It takes a very steady hand to execute the "shot glass on shot glass" maneuver Dr. Boyd pulls off...twice. Find out how this helps explain fluid diffusion and fluid density in this cool video! Minute 0:30 – Introduction Minute 0:52 –...

You can make something that usually sinks—like an egg—float with this simple science experiment exploring density! #ActivitiesCorner Stay curious with more #BritannicaKids activitiesttps://kids.britannica.com/activities' target='_blank'...

Make a fun Halloween density potion, the water and oil doesn't mix even if you shake the jar.

Learn how to make antibubbles and the science behind these fun, unusual spheres. This cool and unusual demonstration is an easy DIY experiment. Antibubbles are a spherical shell of air enclosing a droplet of water, all submerged in...
