Lesson Plans for Astronomy: 9/23/13 – 9/27/13

MONDAY: Today we will discuss what makes an investigation scientific rather than secular. We will look at hypothesis, theory and law to see how science uses each of these in a particular way. Next we will see how these were applied by early astronomers and scientists which resulted in the development of our heliocentric cosmology. You understanding will be checked as we answer EOCQ2 4-9 and 18-19. Homework: Download the SG for chaper2 (here) and have a hard copy in class with you on Tuesday. The test over chapter 2 will be on Friday.

TUESDAY: We will look at the contributions of Kepler and Newton today discussing the laws of the universe which they literally discovered. (Can you imagine discovering a UNIVERSAL Law?!) You will be required to know these laws by memory for the test. Your understanding will be checked as we answer EOCQ2 1-3, 10-15 and 23. Homework: Do Wednesday’s 3mQ and the Friday portion of it as well. Mr. Young cannot help with this 3mQ unless you show evidence of at least writing the question as and answer.

WEDNESDAY: Today, in Mr. Young’s absence you will work on the chapter 2 study guide in preparation for Friday’s test. You will turn in the answers to the following questions by the end of class: 1, 6, 8, 9, 12, 16, 22, 24, 27, 36, 43-45 and 49.

THURSDAY: We will review the SG today. By the end of class all of these questions will be answered and then all you have to do is know them for the test on Friday. Homework: Finish up the 3mQs so that they can be turned in first thing on Friday before you take the test.

FRIDAY: Take the chapter 2 test today. Homework: Read chapter 3:0-4, take notes and answer EOCQ3 1, 2, 5, and 16. Also download the chapter 3 0-4 study guide here. You will need to have this on Monday.

3mQ Astronomy Monday 09/23/13

1.       Which of the ancient Greek philosophers put forth the idea that the universe is governed by regular laws?

2.      What is the function of a theory, of a hypothesis, of a law?

3.      If we spoke Greek and said ‘planet’, of what would we think?

BONUS: What is an epicycle? Draw one.

3mQ Astronomy Tuesday 09/24/13

  1. What conclusion did Copernicus draw from the fact that Venus and Mercury were never very far from the sun?
  2. What is the name given to the position at which Mercury and Venus are most easily seen because they are highest in the sky?
  3. What was T Brahe able to do regarding the positions of the planets that no other astronomer before him was able to do?

BONUS: Consider two objects, one is three billion times the mass of the other; how much force is needed to keep the more massive object going at constant velocity than is needed to keep the less massive object going at constant velocity?

3mQ Astronomy Wednesday 09/25/13

1.      What is the equation for Kepler’s 3rd law; to what does Kepler’s 3rd law apply?

2.      Write the equation for Newton’s second law; describe three ways in which an object can accelerate.

3.      Is it possible for Newton’s third law forces to act on the same object?

BONUS: What determines the weight of an object; what determines the inertia of an object?
