Boats, ships, submarines, or a pleasant swim at the lake are all possible because of the buoyant force. In fact, buoyancy is the upward force we need from a liquid to stay afloat.In this simulation, you will learn that the fluid density and the submerged volume of an object both influence the buoyant force. Do you think you will be able to help Archimedes design a perfect swimsuit for Dr. One and help her enjoy a trip of ultimate relaxation at the lake?

Floating and sinking objects

加入One博士在我们的虚拟实验室中，并尝试对物体的重量以及这如何影响其在液体中的位置。您将有三个带有不同重量的球，还有一个坦克，里面装满了从湖中收集的水样品。

During this experiment, you will investigate how the densities of both the object and the fluid affect buoyancy. You will also understand what exactly causes something to float or sink, and the relation between the buoyant force and the object’s weight for a floating object.

Play with different liquid densities

You will have the possibility to fill up the tank with three different liquids. This experiment will explain how the fluid’s density affects the submerged volume of an object. You won’t just intuitively guess the position of the balls in the tank, but you will also evaluate the submerged volume of the balls using equations. You will look at how the submerged fraction of an object relates to the ratio between the densities of the object and the fluid it is immersed in. But don't worry! Dr. One will be there to explain and guide you through the terms of each equation.

The shape-shifting ball

It is time now to understand if the shape of an object can also influence its ability to float or sink. You can find this out by playing with a magic ball, which is able to change shape with the click of a button. Will you be able to solve this mystery? You will need this last piece of information to be able to help Dr. One float on her vacation!

Help Archimedes

At the end of this simulation, you will use your knowledge on the buoyant force to help Archimedes design a perfect swimsuit for Dr. One, and allow her to enjoy a trip of ultimate relaxation at the lake. Of course, you will be able to test your piece of art and see if it works!
