Physics 2-17-21 Chapter 7 Test Overview

PHYSICS: Good to see some of you today! Here’s our overview of the Chapter 7 test. It will be an open notes test that you’ll take on PowerSchool Learning. First open notes – not open book, not open Internet, not open anything but your brain, your own personal notes, your calculator, and the Lord Jesus.

Time: The test will open at 10:00 A.M. and I’ll close it at 2:00 P.M. You do not need a password. You can have 90 minutes to take the test, but it’s a regular length test so I don’t think it will take that long. Let me know immediately if something isn’t working for you. You will not Zoom in to take the test.

Format: There are 3 sections. First, Multiple Choice. You’ll answer the multiple choice in PSL. If I were you, I’d have notebook paper for scratch work for these. Next, Discussion. You’ll answer these on your notebook paper. There is one that you have to answer, and two others of which you will pick one to answer. Finally, Problems. There are six problems and you’ll pick five to work. Answer these on notebook paper.

How to Turn It In: When you’re finished, you’ll submit your PSL mulitple choice answers only via PSL and you’ll scan your scratch work, discussion, and problems as a PDF and submit them to your Google Drive shared folder. Include in the PDF title, Ch 7 Test. Text me when you’re done and have submitted everything so that I can check to make sure I can see your work.

God bless you as you study and prepare!!

Chemistry 2-17-21 Activity Series & Completing Chemical Equations Review

CHEMISTRY: Happy snow week! Here’s the lesson for Wednesday. It’s the LAST of the notes from chapter 8. At the end is a great review of completing and balancing equations. Also be sure and check the syllabus to find out about the optional homework assignment that will be great help if you’re having trouble predicting products of reactions.

So guess what happens when a gummy bear falls into a test tube of molten potassium chlorate?! Click on the video below to find out! Do you reckon that it’s a physical change or a chemical change? Why do you think?

Remember these steps when you are completing chemical equations: #1 – write the correct formulas; #2 – ask yourself what type of rxn it is; #3 – find the rule that applies and go for it! Don’t forget also that if you answer single replacement to #2 (or the synthesis or decomposition of a metal oxide!) you’d better check the activity series first!! Good luck!

Hon Chemistry 2-17-21 Structure of the Atom

HON CHEMISTRY: Happy snow week! Here’s the lesson for Wednesday! As you watch and take notes, follow the connections the scientists made as they discovered the structure of the atom. Do you think there could be anything smaller than protons, neutrons, and electrons? Hmmmmm……

Make sure you know the name of the scientists, the name of their experiments, be able to draw a diagram of their experiment, and describe how they interpreted the experimental results that led to their discoveries.

Here are some extra video clips to go with the lesson for today. They’ll help you review the different experiment that the guys like Thompson and Rutherford did. Click here for the video on the Cathode Ray Tube Experiment that Thompson did, and also for a little history on The Discovery of the Electron. Here’s the other one on The Discovery of the Nucleus.

By the way – do you think you could do what they did – figure out what something’s made of without seeing it?
