Learn how to prove the buoyant force on a submerged object equals the weight of the water it displaces. This quick experiment makes buoyancy easy to understand.

This Design Squad Nation animation shows how the water displaced by a boat produces a force that pushes on the hull and supports a boat. For more videos, activities and games visit pbskids.org/designsquad

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...

In this video Paul Andersen explains how density measures the compactness of a material. You can calculate the density of a material by measuring the mass and dividing this by the volume. Water displacement is an effective way to...

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...

Learn the basics about Displacement reactions and reactions in solutions. What are displacement reactions? and what they in solutions? Find out more in this video!

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...

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.

You throw a rock in water from your boat. Can you figure out what happens to the water level?

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.

We've learned before here on SciShow Kids how boats can float on water using displacement! Today, Bill and Webb will show you how to build you own boat and see displacement in action! Anchors aweigh!

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...

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...

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...

How does a small life vest keep a large human from drowning? Discover how life vest manufacturing uses physics to keep us safe in water.

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...

Louisiana still is learning from Hurricane Katrina. Forecasts are dire for Louisiana to experience the second-highest sea level rise in the world. There is a big movement brewing in New Orleans to build adaptive "resilience zones." In...

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...

Using stones to raise water in a pitcher isn't just the stuff of Aesop's fables: this experiment shows that crows have an understanding of water displacement. Read
