Ecosystem unit introduction

 Today we will begin a unit on Ecology.  This is the  Ecosystem worksheet. 

Copies might be found  at the back of the room. If not, answer the questions on a separate sheet of paper. If I am back before the end of this week, we will go on a field trip to Trout Lake to examine parts of the ecosystem.

please view my lecture on ecology and do the worksheet and study this content for the  upcoming  (online open book) quiz next week which will include this content as well as chem content.

Solid Carbon Dioxide: The Dry Ice Lab

 safety precautions: 

1. Do not inhale the gas coming out of the flask

2. Do not put the ice in an enclosed container and do not take the ice out of the classroom

3.  Report ALL accidents, no matter how minor and even if you are at fault. There will be no academic consequences for reporting accidents even if your actions led to the accident.

4.  Work with others respectfully without horseplay. 

Today you will do this solid carbon dioxide lab

Do a Bohr Diagram exercise called "Periodic Table Basics"

I would like you to answer the questions on another sheet of paper: The ones on  this worksheet to practice . You may need scissors and pencil crayons to do this activity. Ask the teacher to look in one of  the back rooms for a set of scissors. If none can be found, then just answer the questions. The remainder of the class could be a study block   (copyright T. Trimpe, 2002). 

Learning about Bohr Diagrams and Lewis Diagrams - with Answer key

    

We will practice drawing Bohr Diagrams and Lewis diagrams.   You should work through this Study guide on the same topic  and the Answer key   Finish these two worksheets and upload pics of your covalent compound "cookies" upload them on TEAMS  for 5 marks.  

Calcium demo and lab report

 Assignment:   Write up our lab on Calcium and water. 

image by Katelyn M

 Your lab must include the following

1.  First and Last names of all investigators

2. Purpose of lab:  The purpose of the lab is to find out what happens when you add calcium to water.  Describe the teacher demo that preceded this lab. 

3.a Materials: write a complete list of materials that we used including the litmus paper at the end.

b.  Safety:  list the safety precautions for this lab

4. Procedure: Draw a cartoon to describe the step by step procedure  that is so well written that another person could read it and replicate your actions exactly. You may also upload pics demonstrating your procedure.

5.  What is the question we are trying to answer?  For example there were two possible gases that came out of this reaction.  What gases were they?

6. Results:  Describe in detail what happened after you did the procedure.  Include any photos you took.  How did you know you made the gas, which gas?  

7.  What was the white stuff?  How did you test for the identity of the white stuff? 

8. Write your conclusion in paragraph form.  


EVALUATION   IS OUT OF 25 IN TOTAL

5
presentation is out of 5.  for 5/5 it is typed  with illustrations or photos and handed in electronically or on paper

     for 4/5 it is pretty good but there are a few spelling mistakes.  for 0-3 out of 5 it is in pencil or messy.  I prefer this to be printed

10
Clear writing is out of 10.  for 9/10 or 10/10, it is written with no English mistakes and it clearly communicates each part of the lab report.    7-8/10  it is very well written     for 5-6/10 some parts are not so clear and the reader must guess what you are trying to say.  0-4/10, it is minimally communicating what happened

10
Paragraphs are insightful and your observations are well done. this is out of 10.
             9-10/10,   your observations and conclusions are well written and logical.  It is brilliant
              7-8/10   your observations and conclusions are very well done
               5-6   your conclusions don't really logically follow from your results
                0-4   your conclusions are not relating to your results at all
      

ACKNOWLEDGEMENTS
write all names and who contributed what including the % of their contribution. so two people who contributed equally would be50%

Writing Ionic Compounds

Review the rules of writing compounds.  

 Nomenclature practice sheet. Do these practice sheets for 5 marks 

Answer key is here 

The Game of Compound

I asked you to make a deck of compound cards using the list of Common Ions which I gave to you in class.   Don't just make one of each card, make lots of repeat cards of the same ion so that the deck can be used to play a game.  Include as many of the ions as you can.   The challenge is to create a set of cards which can be used to play solitaire.  Hand in your set of  compounds.  

Practice making at least 15 compounds, write their formula and write their name! 

Here are some patterns on the periodic table.  Colour code your periodic table according to these patterns
