Physics 10-23-20 And Did the Hammock Crash?

PHYSICS: Great work today thinking through this one and also the “Wanda has a sign” problems! How you look at problems from the beginning can make a huge difference – huh?

A couple of things that work for me when doing equilibrium, etc., problems – first, draw them. Then go back through and separate resultants into components. If an object is in equilibrium, then there are no net forces – all the forces in the x direction balance – everything left equals everything right, and all the forces up equal all the forces down.

You’ve got all the ammo you need, now go forth and conquer!

Answers for the Equilibrants II worksheet are below:

  1. Fn = 3430 N upward against feet
  2. Fn1 = Fn2 = 1890 N upward on each foot
  3. F forward = 4.59 N
  4. T1 = T2 = 1760 N
  5. T1 = 1360 N and T2 = 680. N

Chemistry 10-22-20 Chapter 1 Test Help Session

CHEMISTRY – Are you ready? God bless you as you study! Here’s the help session from this morning – good stuff!! (FYI – I didn’t put on the mic until about 24 seconds. Crazy morning!)

Make sure you aren’t just reading your book and notes. First, memorize the facts, then go back and make sure you can apply the concepts. Study examples, make your own examples, practice making questions. And don’t forget, if you are getting lost with everything you need to know, or if you’re not sure how to study, Chapter 1 Stuff to Know Sheet under the Test Info tab

Don’t forget the Chapter 1 Pre-test. Scroll down here on the web site for the web post from yesterday to find it. Also remember there are great review games that are in the Student Premium section of the online textbook. You can do this – I believe in you! I’m praying for you!!

Chemistry 10-20-20 Elements & Intro to the Periodic Table

CHEMISTRY – Wow! Do you realize what we just did?!? We finished the chapter!!! Did you feel like today was mostly review?

The elements that you are going to research for the test are Cu, Si, and P. A great resource to research the elements are these video clips on copper, phosphorus, and silicon that a group of chemistry researchers have put together at www.periodicvideos.com. Watch these and take notes. The information on these video clips will be on the test.

Hey, have you had a chance to check out the chapter 1 study suggestion sheet? Let me know if there is anything you need help with before the test! (And you’re still learning the symbols of the elements, right?!?)

Chemistry 10-19-20 Classifying Matter, Pt 2 and Energy, Pt 2

CHEMISTRY: So if I gave you an unknown substance, could you begin to ask yourself questions to determine what type of matter it is? Could you design an experiment to find out? And which has more heat – a burning match or an ice burg? So many ways to apply what you know today!!

And wow!! The paper cup with water did not burn! Why? Today we finished notes on the classification of matter and we also finished notes on energy. So why did the paper cup with water not burn in the flame? Wow! And why? Hmmmm……

Chemistry 10-16-20 Classification of Matter, Pt. 1

CHEMISTRY: Here’s a mixture that looks like it might be worth investigating – bacon caramel popcorn! I mean, I like bacon and I like caramel popcorn, but bacon caramel popcorn? Hmmmm….

So now that you know about mixtures, could you figure out how to separate one? Keep these notes handy!
