Wondering how you can catch the perfect wave? Dive into the fascinating and complex physics of surfing. -- Whether or not you realize it, surfers are masters of complicated physics. The science of surfing begins as soon as a board...

Join us as we investigate a classic question: what happens to the water level in a glass when a chunk of ice melts? Learn about buoyant force, density, and volume displacement, and witness the principles of physics come to life before...

When metals react they lose their outermost electrons. This video covers which metals are the most and least reactive & also how we can determine reactivity by reacting them with acids and water. Then at the end we cover displacement...

Through real world examples, students will come to understand that chemical reactions cause reactants to undergo changes, so the products have different properties. Viewers will learn about single displacement and double displacement...

Learn the basics about reactions of iron, as a part of chemical reactions.

This program begins by discussing common ways mass and volume are measured in the home. The video highlights how mass and volume are measured with various types of equipment in the school science lab. Some of the different tools used to...

Stories of discovery and invention often begin with a problem that needs solving. Summoned by the king to investigate a suspicious goldsmith, the early Greek mathematician Archimedes stumbles on the principle that would make him famous.

This video explains different methods of measuring the volume of liquids and objects. It demonstrates the use of tools such as beakers, graduated cylinders, and water displacement to accurately measure volumes. The video also highlights...

It’s time to meet some extraordinary Australians who have done lots of extraordinary things! Meet David Unaipon, Cathy Freeman, Jessica Mauboy and Hein Bergerhausen – discover what makes these people so incredible!

Along the way,...

This engaging program helps students comprehend the concept of volume. Easy-to-understand examples illustrate how the volume of liquids are measured. Measuring solids is shown using a ruler, or through the process of water displacement.

Archimedes principle states that if an object is submerged in a fluid, then the buoyant force acting on it is equal to the weight of the fluid displaced by that object. Buoyant force exists because pressure increases as an object goes...

Archimedes is not just the owl from the Sword in the Stone. Although that's a sweet movie if you haven't seen it. He was also an old Greek dude who figured out a bunch of physics way before other people did. Some of this was discovered...

The best way to know how to do calculations and report your answers to the correct number of significant figures is to practice! In here there are a few opportunities to check your understanding of this concept.

Hurricane Katrina was historic, not just for size and strength but for way it hit the Mississippi Gulf Coast, and southeastern Louisiana. It led to death, destruction, displacement, and suffering, particularly in New Orleans. See the...

This video explains how to calculate the force experienced by an object when it is submerged in a fluid, specifically focusing on upthrust and fluids. The video also covers the concepts of pressure, density, gravitational field strength...

It explains density and its unit, relative density and determination of relative density of a solid.
