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.
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. 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%
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. Photograph your set of compounds.
Evaluation criteria
18-20- your cards are complete and you were able to make a variety of compounds. The deck is very creative. And the writing is legible, in ink or typed.
15-17 - your cards are comprehensive but not totally complete. The deck is written in pencil.
10-14 - your cards are a good start and almost a complete set. the deck is written in pencil
0-9 - your cards are pretty good but they are not yet complete. You need to complete this assignment.
In our first lesson we will go over science safety and start out with studying the ATOM.
I will do a lesson on phase changes of atoms demonstrating SOLID, LIQUID, GAS.
I will ask you to write a paragraph describing our demo and also explaining phase changes in solid liquid and gas
Assignment 2: summarize the class activity SOLID LIQUID AND GAS and explain how I did the demonstration using the following words: solid, liquid, gas, evapouration, condensation, absolute zero, thermal energy, space between atoms. draw a picture of the demo.or cartoon, or photograph.
completed summary: /10
8-10 / 10 - you explain the concepts in clear language and use all vocab words. You are an exceptional communicator and you are correct. your grasp of the concepts are excellent.
6-7/10 - you do an incredible job of summarizing and explaining the concepts. you miss a few of the words
Assignment 3: Practice questions: What is an atom?
An analogy for Atoms, Compounds and Formula, drawn by SN
This video is the first in the series for beginner Chemistry. In this video, I use the analogy of the atom as units very much like "lego bricks". This analogy was first used by researchers in MIT.
assignment :
1. Please do this worksheet in pen and also photograph it :
1. Take a good look around our science room and imagine we are just about to do a lab were each student is given a flask of acid, a candle and magnesium. Identify ALL POTENTIAL HAZARDS in point form
2. Identify ANYTHING IN THE ROOM TO MITIGATE those hazards! in point form
3. DRAW A MAP showing where the safety equipment is for all the things you mentioned in number 2
evaluation:
9-10/10. Your assignment is complete, neat creative and inked and coloured
7-8 Your assignment is complete, neat creative and really well done! it is in pencil
3-6. your assignment is a good start. it is incomplete.
This course is a lab course which will cover Chemistry, Physics, Biology and Astronomy. It is expected that you will receive most of your course content on line and we will do labs and field study in class. You will hand in ALL assignments through Microsoft Teams. I have set up my class so that the majority of the class notes shall be distributed on line from this blog.
The majority of class time will be lab work (chemistry and physics experiments, microscope work) and also field study (walking to Trout Lake). My windows shall be open ALL THE TIME to give us nice fresh air so dress warmly!
ASSIGNMENT 1. HAND IN YOUR CONSENT FORM /5
It will give us the ability to walk to Trout Lake or Renfrew Ravine or Central Park at any time that I announce during the term. Bring this consent form to class.
evaluation: 5 points for handing this in
As we go into your semester, I would like to prepare for learning during the second wave of Covid 19. I would like to remind everyone that the best way to protect one another in class is to keep our distance (2m), wash our hand frequently AND to wear a mask especially in indoor spaces. Further, the greatest protection you have is getting vaccinated!
I invite you to flatten the curve by these simple measures! We will beat Covid 19 together! Further, all of my class assignments will be posted here on this blog and therefore, if anyone misses any class due to illness, or self-isolation, you can easily keep up with the work.
SAFETY MEASURES:
In class, our safety measures will include:
- physical distance, as much as possible in our class.
- wear a mask! It is strongly encouraged by our VSB! (if you have medical reasons for not wearing a mask, please have your guardian inform me)
- no academic penalties for being home sick, or isolating, or you found out your friend has covid and you think you'd better isolate, or you are afraid of the covid situation.
- windows shall be open in my class to admit adequate ventilation.
- we can conduct class outside sometimes to do field study
- I encourage ALL STUDENTS TO GET THE VACCINE!!! I myself am vaccinated!
- if you do not have the vaccine, the following places are dangerous: ANY SPACE WHERE YOU SHARE AIR WITH PEOPLE NOT WEARING A MASK INDOORS.
WHMIS - WORKPLACE HAZARDOUS MATERIALS INFORMATION SYSTEM THESE symbols are on the MSDS sheet for all chemicals Materials safety Data Sheet. 1. Follow teacher instructions

You will create safety rules by reading and summarizing the safety procedures in your poster The rules can be under the following categories: HIGHEST PRIORITIES: THESE RULES CAN BE SUMMED UP LIKE THIS 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 KNOW THE SYMBOLS Know the correct symbols, WHIMIS symbols
COMMUNICATE AND REACT TO AN EMERGENCY be familiar with emergency procedures for fire, toxins, spills, and evacuation SAFETY ASSIGNMENT: . Make a poster of the safety rules Draw a comic showing all the safety rules on one side of the page.
