Physics 9-29-20 Horizontal Projectile Motion

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 9-25-20 Lighting a Bunsen Burner

CHEMISTRY – Great job lighting Bunsen burners today! By the way, did you happen to see a green flame when you put the copper wire in the flame? The electrons in the copper atoms were being excited and they gave off a green flame. Cool!!

Here’s something you will find useful in the future…everything you wanted to know about a Bunsen burner and how to light it. Be sure and view the slide show BEFORE you take turn in your lab sheets and take the test.

Next week we’ll continue with Parts 4 & 5. Be sure and read ahead before you come to class! Also, make double dog sure you are keeping up with the observations and answering ALL of the questions at the end of the lab on pg. 13 – 18. There are a TON of them!!!

Physics 9-24-20 Graphical Vector Addition

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.

Hon Chemistry 9-24-20 Lab Safety & Procedures

HON CHEMISTRY: Wow! Great video, but do you feel like you have information overload!?

Here is the lab safety video we watched in class. It does have a ton of info, and the thing is, you absolutely must know it – and not just for the test, but also throughout the year in lab. It’s a really good idea to watch it again and take notes as you go.

HOMEWORK: First though, lets talk about homework.(Don’t forget to check your syllabus to see what else is due tomorrow and Monday!!)

Lab Safety ContractSince we’ll be in lab so much, it’s important that you write your own lab safety contract. Here’s how you do it::

  • From the first couple of pages of the Safety Packet that you got in class (or it’s also here under the Lab tab), write the lab safety statements as your contract.
  • They may be handwritten on notebook paper or typed.. You only have to write the first part of the rule that is bold. There are 29 in all and they almost all start with “I will…”.
  • At the end of your contract – after the last statement, hand write the following statement at the bottom: “I agree to abide by these rules.” Then sign underneath and date it. Even if you type the safety rules, you’ll need to hand write this last part and then scan an IMAGE of your hand written statement and signature/date at the bottom.
  • Scan your final document as a PDF and submit it into your Chemistry Shared Folder. You must have this safety contract submitted to do lab for the rest of the year! Due Monday!

Physics 9-23-20 Intro to Vectors

PHYSICS – Hey guys, great job today on the intro to vectors – graphical vector addition, resultants, and the like. Have you done anything like this before? We’ll spend tomorrow practicing adding vectors graphically. Great start today! Don’t forget your protractor and graph paper!

Hon Chemistry 9-23-20 Lab Equipment

HON CHEMISTRY – Hey guys! There’s a ton of useful equipment for chemistry this year! Below is a slide show with an overview of the apparatus that you’ll use in the chemistry lab. Click on the black arrow to start the slideshow. For all of the equipment:

  • Know the name of each item.
  • Explain the use of each item (it’s written in white on the slide)

The second slide show is a great tour of our lab. It’s very important information about where stuff is and what it’s used for. I think you’ll find it very helpful. Both of these would be a great way to study equipment for the test! (Hint, hint!) 🙂

Lab Apparatus Assignment – Study the lab equipment in the slide show below and then, when you know them, identify the equipment in the Lab Apparatus Review on Power School. Once you start, you will have 30 minutes to complete the assignment. It’s due on Monday by 8:00 A.M.. If I counted right, there are 33 of them.

By the way, there is also a Practice Review on PowerSchool Learning that you can practice with before you do the actual assignment. Also, pictures of most of these are in the back of the Safety Packet.

Hon Chemistry 9-21-20 Graphing Exercise 1

HON CHEMISTRY: Today you are going to learn (or review) how to make graphs using data analysis software like Google Sheets or Excel by watching the video below at your own pace.

Here are the instructions for Monday – (You are going to be dreaming about graphs!!)

IMPORTANT: A rough draft of your first graph is due tomorrow by class time. The entire assignment must be submitted by this coming Friday, September 25, 8:00 A.M.

You can do this assignment at school or at home with your own computer. If you use any device other than a PC or any graphing tool other than Excel or Google Sheets, you may need to modify the instructions to fit your device.

  1. Watch one of the vodcasts below for a tutorial on how to make graphs in Excel or Google Sheets.
      • My advice is to use a split screen view on the laptop with the video on one side and Excel open on the other side of your laptop screen. Watch the video and at the same time pause it as you follow along with the steps in Excel. Holler if you need me to show you how to do a split screen view. Or Google it! 🙂

     

  2. When you begin working on the Graphing Exercise 1 assignment, pay very close attention to the instructions. Also, pay close attention to the sheet on How to Make a Best Fit (Scatter Plot) Line Graph in Excel 2010 – UPDATED to make sure you have all the parts of the graph covered.
  3.  

  4. Google Sheets only: If you ever need to add subscript or superscripts to the axis labels in Google sheets, try copying and pasting whatever number you need from this set in to the axis title in Google sheets: ⁰¹²³⁴⁵⁶⁷⁸⁹₀₁₂₃₄₅₆₇₈₉

Now go forth and conquer graphs!!
