Today I chose my PBL Project. I chose the Inertia Force Demonstration. My teacher showed us the project to help us understand the topic of Centripetal Force, since I'm a visual learner, I understood better once I saw the demonstration in action. I seemed interesting to apply physics to a force I have been seeing since I was a boy. Inertia is truly in everything. For example in swings and playgrounds you can see inertia being used for entertainment. Millions of kids see this force in action, but don't know what its called. That is why I have chosen this demonstration for my PBL project. I will schedule an appointment to come after school someday and begin the action video.

Today I film the action video and start taking pictures of the project. I kind of enjoyed mixing the food coloring and the water. I then poured it inside the Rotational acceleration tank, which I had already set up on its base. I, then, connected the motor drive to the tank using the alligator cables. Lastly I turned the motor drive and begin observing inertia in motion. I learned some basic equations such as force = mass x acceleration which can help me figure out the exact acceleration and see how it affect the water

I have been working on my website and I had a hard time adjusting to Google sites. Its my first time making a web site. I asked some of my peers who were in computers class to help me learn the format of Google Sites. I did, in fact, have some practice with filming and video editing, so that part was more of a breeze. I have done videos for Spanish, Social Studies, English, and Speech Communications class. I believe this was beneficial because it polished my talents on video editing. I will admit that I had some trouble with the audio. Specially in the script of the introduction, "The Centripetal Motion Demonstration uses water with food coloring to demonstrate inertia in action.The Rotational Acceleration Tank demonstrates a centrifuge when used on the Rotational Platform. Observing the shape of the red liquid in the tank, students can better understand rotational motion and its relationship to centripetal force. The water is contained in a glass tank with a rotating base that spins on its y-axis to show the centripetal acceleration at work."
