We are beginning a new unit and will study Sir Isaac Newton's Laws for the second quarter. We will first examine Newton's First Law of Inertia: an object at rest remains at rest until a force acts upon it, and an object will continue in motion until friction/an opposing force acts upon it. Our first topic of discussion is gravity and students will test different objects to see which has more gravitational pull and which will reach the ground first if dropped from the same height. This will lead to a discussion of air resistance, mass, and what determines gravitational pull. Next lesson, we will push a box over various surfaces with the same amount of force to determine which surface has the most friction. Finally, students will design paper airplanes with lift, thrust, and aerodynamic principles in mind. The most aerodynamic plane will win the competition.
While we are studying Newton's Laws, I will give students a bit of time to study their Competitive Edge on Monday and Tuesday. The Weather Nine Weeks Test will be on Wednesday.
Homework for the week is the following:
Monday night:
1. Study for the Weather Nine Weeks test using multiple choice questions in Competitive Edge.
2. Pg. 218 #1 and pg. 220 #9 Competitive Edge textbook
Tuesday night: Study for the Weather Nine Weeks Test
Wednesday night: pg. 218 #2-8, 19, 20 in the Competitive Edge
Thursday night: none; there is no school on Friday
