Have you ever longed to swim while wielding a longer snorkel? Well, there are a few reasons why they might be shorter than you'd like.

Ever notice how cereal clumps up in your bowl, or how cereal sticks to the edges of the bowl? Bubbles in beverages do the same thing.You've probably seen this surface tension and buoyancy at work, but did you know there's some...

Mr. Andersen shows you how to sink leaf chads in preparation for the AP Biology photosynthesis lab. An empty syringe is used to remove gas from the leaves before the lab. As the chloroplasts absorb light they produce oxygen bubbles...

Discover the forces at work underwater, which dictate why large boats float but small pebbles sink. Physics - Forces - Learning Points. The buoyant force is an upward-acting force determined by the weight of the displaced water. Ships...

Hot air balloons rely on heat alone to keep them in the sky. How does this work? Physics - Energy And Radioactivity - Learning Points. Hot air rises in cool air because it is less dense. The hot air within a hot air balloon creates the...

Explore the fascinating world of buoyant force with this physics lesson on submerged objects in fluids! Join us as we dive into the principles behind Archimedes' discovery and unravel the mysteries of why objects float or sink. We'll...

Upon viewing the Forces in Fluids video series, students will be able to do the following: Define fluids as substances that can easily flow and readily change shape. Explain that fluids flow because particles can easily move past each...
