Out SciFri video was about motion and forces today, as we start our first unit of content! Usain Bolt is known for his speed running...but can he beat the motion of something due to the acceleration due to gravity?

Sorry this is a little late but here is our SciFri video from last week. What do you think happens to a basketball when it's dropped from a really high height? What do you think might change if you give it a little backspin? I guarantee you wouldn't have expected this! Air and how it interacts with matter really plays a large role in the motion of objects. We'll explore some similar concepts with this in our first major unit about forces. A few years ago I started watching SciFri videos in class, where I would share a cool science video on Fridays. This is the first SciFri video of the year! The question is, "Why is yawning contagious?" I dare you not to yawn when you watch it! |
