In today's lecture, we started off by asking questions. Dr. Ezrailson made a statement that it is important for our students to answer questions and understand the material, which i also believe to be very important. We also discussed upcoming projects, quizzes, and the reading guide which are due within the next week or so. As a class, we spent alot of time discussing the reading guide and the questions it asked. For example, what our opinions were of our scientific learning was in our elementary years and in our internship placements. The reading guide also discusses questions from the reading of chapters 5 and 6. To end the class we did an experiement called "The Leaping Egg;" we used a ping pong ball. We take a plastic (never glass) cup and place a small funnel inside the cup. Within the small funnel we place our ping pong ball and try blowing at it at different angles to see how far the ball would go and what was causing the ball to shoot in those different directions. We found out that the ball shoots out of the glass and funnel because of the exerted force we are placing on the ball. But what happens if we blow on it in different ways? If we blow on the near side of the cup the ball will shoot forward, but if you blow on the far side of the cup the ball will shoot back at us, because of the air current and pressure we force on the ball.
