Hon Chemistry & Chemistry Assignment for Monday

Posted on by

Here is your assignment for Monday. You’ll be working on your extra credit Science In the News assignment today.

IMPORTANT guidelines for the assignment:

  • For today, you can use the laptops in the back of the room, or you can also use your own laptop
  • You will have to print the article at another time. You cannot go to the computer lab today to print your article.
  • Find your article on sciencenewsforstudents.org or sciencenews.org. If you already have an article printed from one of these sites, you can use it.
  • Make sure you pick an article you find interesting and that you understand!!
  • Make sure you pick an article that you can use to answer the questions on the Science In the News sheet. If there are questions you cannot answer with the type of article you have – pick another article!!!
  • The SItN assignment must be handwritten on notebook paper – you may write on the back
  • Check the syllabus for the due date for extra credit.

IMPORTANT #2: When you are finished today, put your laptop up in the correct slot and plug it in!!

Physics 9-27-19 Relative Motion Revisited & a HW Baseball Problem

Posted on by

PHYSICS – Wow, we finally made it to the official end of chapter 3! Do you realize how much you’ve accomplished? Awesome!

How’d you do with relative motion “revisited”? You know, you’ve done this already. The only new part is the motion of objects in the same direction and opposite directions, relative to each other. Don’t forget, you’ll use what you learned about vector addition to work those “boat goes across a river” and “plane experiences a head wind” types of problems.

Also included at the end – a look at one of the angular projectile homework problems – a baseball hit over a fence.

Physics 9-26-19 More Angular Projectiles & the Monkey-Hunter Problem

Posted on by

PHYSICS – Great job today working through the monkey-hunter problem!

Do the problems make more sense now? Don’t give up on the next set! They are tough, but you can do it!

If you need some inspiration – here are links to the Monkey-Hunter videos from class today:

Physics 9-25-19 Angular Projectile Motion

Posted on by

PHYSICS – So we are finally putting it all together – angular projectile motion! Here’s the lesson – some homework discussion and then angular projectile motion. Mic battery died in the middle of recording, so here’s a recording from a looooooooong time ago. I think you will find it helpful. Ahem.

The number one thing to remember – Never use the resultant velocity to do more than find the vertical and horizontal components! And vertical is vertical, horizontal is horizontal and don’t ever mix the two!

Physics 9-24-19 Horizontal Projectile Motion

Posted on by

PHYSICS: Great job today – and applying stuff from the last chapter no less!

Just go slow and easy, talk yourself through what you are doing and ask if the formulas you are using are legit. You’ll master it in no time flat. Watch out for squirrels throwing nuts!

Hon Chemistry 9-24-19 Physical & Chemical Changes and Conservation of Mass

Posted on by

HON CHEMISTRY: More review today on chemical properties and chemical changes. Can you determine if a chemical change has occurred? And what about energy? How is that important in chemical changes? Let’s play with a chemical change tomorrow!

Physics 9-23-19 Component Method of Vector Addition

Posted on by

PHYSICS – Great job today!! You are on your way to conquering the component method of vector addition. So which do you like better? Give yourself a chance to get used to separating everything into x and y and it will click, I promise!

Hon Chemistry 9-23-19 Intro to Chemistry

Posted on by

HON CHEMISTRY: So now that you know how to use all the tools we’ll need in chemistry, it’s time to start talking about ….chemistry!!

Were you able to able to make applications with the branches of chemistry and categories of scientific work? We’ll finish talking about the properties of matter tomorrow. Don’t forget the applications!

Now it gets interesting! 🙂

Chemistry 9-20-19 Technology 101 & Lab Reports

Posted on by

CHEMISTRY: Great job today beginning the journey of learning to write digital lab reports. Be sure and follow very carefully the directions in the Tech 101 Assignment sheet. Everything in the Tech 101 assignment is there to teach you something that you will need to know how to do to write up lab reports.

Two GREAT apps for your phone that will make your lab report writing life SOOOO much easier are the Google Drive app and Scannable (iphones) or CamScanner (android phones.) With the Google Drive app you can send lab photos from your phone directly to your drive and then insert them directly into your lab report. Huge time saver! With the Scannable app, you will be able to scan in your handwriting, calculations, etc., without having to use a scanner. So very helpful for this year – and I use it all the time in my every day life!!

For the future, here’s an overview of your workflow as you write up labs:

  • First, you’ll write your lab in Word or Google Docs, CAREFULLY following the Digital Lab Manuscript Form guidelines
  • Convert your Word document or Google Doc to a PDF
  • Upload the PDF to Google Drive in your Class Shared Folder
  • AND upload the PDF to turnitin.com

Instructions for using turnitin.com are on the Tech 101 sheet. If you already have an account you can use it – you don’t have to set up a new one. Here are the class codes – be sure and use the code for your class period!!

Chemistry 4 – 21813776
Chemistry 6 – 21813804

Physics 9/19/19 Graphical Vector Addition

Posted on by

PHYSICS – Hey guys, great job today drawing motion with vectors – graphical vector addition, resultants, and the like. Have you done anything like this before?

A couple of super important things – GRAPH PAPER(!) and sketch it out before you start so you’ll know where to place the first vector with out running off the page. Also, graphical addition is adding vectors head to tail – then the resultant is found from the tail of the first vector to the head of the last vector. Get the direction by measuring from the tail of the resultant.
