Liquid Density
We compare the density of oil, salt water and fresh water using displacement tanks. Equally weighted measuring cylinders are placed into the three liquids and the amount of water displaced is collected for comparison. Physics - Forces -...

How to Make a Layered Density Tower
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 explain a bit - to...

Science Experiment: Density with Two Glasses
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...

Polymer MFR Regression
Polymer properties such as density, melt index, and melt flow rate must be kept within tight specifications for each grade. This case study is to analyze polymer production data to predict melt flow rate. 0:00 Introduction to Polymer...

Underwater Volcano
We create an underwater volcano by placing a conical flask of hot coloured water in a tank of cold water. The hot coloured water rises through the cold, demonstrating convection. Physics - Energy And Radioactivity - Learning Points....

Seven Layer Density - Cool Science Experiment
The densities of a variety of liquids are demonstrated in this simple, yet effective experiment. Liquids such as honey, dish soap, cooking oil, water, rubbing alcohol, and corn syrup are put on top of one another in a large beaker,...

Amazing 9 Layer Density Tower - Sick Science! #012
This is a strong visual display of density. It requires a mountain of materials and is quite messy, so you most likely will not want to have lab groups perform this activity. You could demonstrate it for your class when exploring the...

Dancing Raisins - The Bubble Lifter
Here is an engaging demonstration of density that you can do with your young physical scientists. Place different rough surfaced objects into carbonated liquid. The carbon dioxide bubbles collect on the surface of the objects and...

Egg in a Bottle...The Tricky Way - Cool Science Experiment
A teenaged Jack Spangler demonstrates how reducing air pressure in a bottle can pull a boiled egg inside. Then dad does a similar demonstration using liquid nitrogen to reduce the air pressure. Even though the result is the same, the...

Water - Liquid Awesome
If H2O is water and H2O2 is hydrogen peroxide, what is H2O4? Drinking, bathing, and cooking among others. Viewers of a short video explore water through its molecular structure, its ability to stick to itself through adhesion (cohesion...
