Today quarter grades were posted. If you want to improve your grade before your parents see it, you have until next Wednesday to do so. I will have all classes' lab books graded by then.
Parent Teacher Conferences are next Thursday, October 28th. We have a half day of school in the morning, I believe school will release at 11:30 (it changed this year from 10:50 in the past), and conferences run all afternoon. I believe the official hours are 12:30 to 7:00pm; I will update here when I have the official information.
Students: The good thing about parent teacher conferences (besides getting a half day and knowing that your parents go to talk to your teachers about how wonderful you are...) is that there is no school on Friday! (the 29th)
Parents: you will be getting phone calls from your child's advisory teacher (not necessarily a teacher of a course they have). If they leave a message, they should include information about conferences and how to call them back, at 636-296-5210 and their extension number. Please call back and let them know you got the message.
The other thing that will be mentioned is grades online and how to access edline; if you don't have a login/password, email hoelzer@fox.k12.mo.us with your name and your child's name, and Judy will get you started.
Today in class we learned about satellites and orbit, and that there is no such thing as "zero gravity" , only situations where an object is in "free fall" and feels weightless. All satellites are constantly falling toward Earth and accelerating due to gravity. As long as they don't speed up or slow down due to an external force, they will remain in orbit indefinitely.
We also learned how to use the Fg = (Gm1m2)/r^2 equation to find an object's weight, and practiced using scientific notation in calculators. Tomorrow we'll emphasize the effects of changing mass and radius on an object's weight, with a bit less math.
