Astronomy: Natural Science 1740

Today:

Today is the last day to do lab #2!

The average score on the MasteringAstronomy quiz was about 60/100. That's about what I expected, in part because I will always include some challenging questions on quizzes. We'll do lots of MasteringAstronomy quizzes, and homeworks as well, so there's plenty of chances to improve if you got a low score. You will always be able to rework the quizzes for practice after they are due, including viewing hints and requesting correct answers.

The SECOND quiz at MasteringAstronomy.com will be available later today. It is still about Chapter 2, and is due in two weeks (Thursday Oct. 20th at 11:59 pm).

There is also a Chapter 2 Practice Homework available, due Monday October 24th. It is worth only half as much as a quiz, but there is no time limit. You have multiple attempts at the right answer, and can view hints, but you get more points if you get the answer right on the first try and if you do not use hints.

Current reading: Chapter 3: sections 3.1 and 3.2 by Monday Oct. 17th; sections 3.3 and 3.4 by Wednesday Oct. 19th.

Draconid meteor shower tonight and tomorrow night... look for meteors appearing to come from the direction between Polaris and the bright star Vega

Constellation help session Wednesday night next week, from 8-10 pm, IF clear at 8 pm. York University Observatory also open at 9 pm Wednesdays if it's clear.

The Monday after fall term break, you will have a guest lecturer, Prof. De Robertis. There will not be an in-class activity, but I will be taking two or three exam questions from the lecture. Give Dr. De Robertis your full attention, and take notes!
