10/14 Class

Today, class began with Dr. Ezrailson discussing our midterm projects. We have already chosen our partners and now we need to choose a topic to present. She let us know that the projects are not to teach students specifically about safety, but to include a safety component to inform our students of possible safety issues during the lesson. This discussion cleared up many questions I had regarding to the project. Next, we went over our Module Two study guide for chapters three through five. Dr. Ezrailson discussed in depth about potential and kinetic energy. She drew a diagram of a bowling ball falling as a visual aid for a more clear understanding. I learned that in the middle of the ball falling the kinetic and potential energy are equal. We discussed that simple machines we are able to save time and work at the cost of distance. Also, we discussed how the moons gravitational pull and the sun create tides on earth. The different pulls of the moon stretch the earth, producing ocean bulges that extend nearly one meter above the average surface level of the ocean. We also talked about projectile motion and escape speed. This discussion cleared up most of the questions I had about the study guide, and I feel more prepared to take the quiz.
