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

LESSON: Chemical reactions may be categorized as follows : 

1.     Synthesis

2.     Decomposition

3.     Single replacement

4.     Double replacement

5.     Combustion

       Cellular Respiration

6.     Oxidation of metals

Synthesis reaction:

element     +   element    -->    compound

Decomposition reaction:

Compound    -->   element     +     element

Or

Compound --> smaller compound    +   element

DOUBLE REPLACEMENT


single replacement

IN ADDITION TO THE FOUR TYPES ABOVE, THERE ARE ALSO THREE MORE KINDS of reaction TO KNOW: 

Combustion:  combustion may happen to any *organic compound* meaning any compound made of carbon, hydrogen and/or oxygen...

Carbon based compound+ oxygen --> carbon dioxide + water

+ heat and light energy

Cell respiration looks like combustion,

BUT IT IS NOT. YOUR CELLS ARE NOT COMBUSTING.  The carbon based compound in this case is glucose, a simple sugar.

Glucose +   oxygen -->  carbon dioxide + water + energy for cell

Oxidation reaction

Metal +  oxygen   -->   metal oxide

ACID BASE REACTIONS ARE ALL NEUTRALIZATION REACTIONS

In summary....

 

Liver Anyone?

 

In the human body, ENZYMES help speed up chemical reactions. 

Today we take a piece of raw pork liver and add it to Hydrogen Peroxide.  Raw liver contains an enzyme called "catalase" which has a job of breaking the bonds in hydrogen peroxide.  When those bonds are broken, atoms rearrange themselves and new products are formed.  

In today's lab, we discover the new products

Science Observation and Measurement Activity

 In this lab you will take the following measurements and you will tell me how you arrived at your answer

1.  Find the volume of our classroom using only metre sticks.  Enter the data on the chart on the side of the class

2. Find the mass of the science chair using only a bathroom scale

3.  observa n interesting object under the dissecting microscope. Measure its size in the field of view.  

4.  Measure the volume of a  REGULAR shape of your choice

5.  Measure the volume of an IRREGULAR shape of your choice.

Show your work and hand this in . There are 5 points per question

Safety

 MAKE A POSTER SHOWING   SUMMARY OF ALL THE RULES

and have a look at this standard science safety quiz

1. 

                         WHMIS -  WORKPLACE HAZARDOUS 
                         MATERIALS INFORMATION

      Talk to the instructor                     

KEEP ORGANIZED AND SAFE
Keep the classroom safe
Keeping your work area safe
Keep safe with your colleagues
Keep yourself safe

     be familiar with emergency procedures for fire, toxins, spills, and evacuation  


SAFETY ASSIGNMENT: . Make a poster of the safety rules 

Make a safety poster which is 

Exceptionally creative and it stands out  It includes all the WHMIS symbols and all the science SAFETY rules listed above . It is done in colour and ink  22-25/25

Your poster is very creative and artistic and includes all the WHMIS symbols and all the science rules . It is done in pencil  18-21 

all the WHMIS symbols and all the science rules . It is mostly done and needs a bit extra work 10-15

This is a good start and seems like a great draft. It needs more time to complete it. 0-10

Chemistry Karate Practice!

 This is the  Chemistry practice sheet Here is the Chemistry practice sheet key.

Do the work on this practice sheet on your own piece of paper up to page 11.  If you finish, you can continue your practice.   Take breaks as you need to! This is hard work!

 10 marks for completing this. 

later,  is an activity next week called " Chemistry Karate"  where your chemistry skills will be respectfully assessed by myself and by peers and you will demonstrate your level of chemistry karate belt.  The goal is to move up one belt, not for everyone to be a black belt !
