Today I invited you to a fancy French restaurant and served you "red wine or white wine"...
Do an experiment with three unknown chemicals. Write up your experiment in a lab report. Use your knowledge from the Acids and Bases notes to deduce what happened during our little magic trick. Write up your experiment.
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.
The FOUR Factors that affect chemical reaction are as follows:
TEMPERATURE - hotter means faster because the molecules have more thermal energy.
CONCENTRATION - the more concentrated the reactant, then the reaction moves faster! (strong acid will react faster than weak acid)
SURFACE AREA - if you chop the reactant in smaller pieces, you increase the surface area and the reaction goes faster!
CATALYST - add a catalyst like liver enzyme, (remember our experiment with raw liver?) and the reaction goes faster!
We saw an example of this in the DRY ICE experiment you recently did! (picture below )Remember when we put hot water with the dry ice? The carbon dioxide came pouring out fast!
in light of our recent covid-19 exposure alert at school, I would like to empathize with you that this is a worrying time. I know that VCH has already contacted the parents and guardians of the class where the exposure has occurred. If you have not been contacted, you are not at risk.
Our school has excellent protocols and in my class, these are the layers of protection, which are similar to many workplaces:
- students wear masks in our school (with very few medical exceptions) and in my class, all wear masks.
- we ask students who are sick to stay home.
- we avoid physical contact and I encourage students to maintain physical distance
- for many classes, including mine, windows are open at all times, admitting fresh cold air (my students need to wear a coat!). Students can also request that windows are opened.
-there are less than 15 students in the class
I invite my students to come to school , wear a mask, and learn with us. We will get through this together!
complete this work for 5 marks YOUR NAME MUST BE ON THE SHEET.
ASSIGNMENT 8: In class practice sheets. Show me a picture of your in class practice sheets all done. YOUR NAME must be on each sheet. Complete for 5 marks. fyi I will post an answer key soon
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.
The video above explains the law of conservation of mass
Assignment 7: Write up our lab on Calcium and water.
Your lab must include the following
1. First and Last names of all investigators
2. Purpose of lab: write about how this lab illustrates the law of conservation of mass. Explain how the lab relates to the law 3. Materials: write a complete list of materials that we used 4. Procedure: write a step by step procedure (including illustrations if it makes it clearer) that is so well written that another person could read it and replicate your actions exactly 5. What is the question we are trying to answer? Write the two chemistry equations which were our possible outcomes of this reaction? Oxygen gas or Hydrogen gas? 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? And was it Calcium hydroxide that was made? How do you know?
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 emailed to msngscience@gmail.com. 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%
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.
Please do this worksheet in pen and also photograph it and hand it into teams
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!
I would like you to download this consent form and bring it to class. It will give us the ability to walk to Trout Lake or Renfrew Ravine 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 Quadmester 2, 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.
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:
- a cap of 15 students in every class
- physical distance, as much as possible
- 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
- windows shall be open in my class to admit adequate ventilation.
- we can conduct class outside sometimes to do field study
You will be invited to come to TWO SESSIONS of my class and you can leave at any time (since it is optional). The schedule will be sent to you through MS Teams.
Please note that my class will be conducted entirely outdoors RAIN OR SHINE and you should arrive to school dressed to be out in west coast weather while you attend my class. We will do a species inventory project on school grounds. You will be taking pictures of plants and bugs and identifying these with a species identification app. This project does not have to be done on school grounds and can easily be done at or near your home. It is due on June 18, through MS Teams
After this assignment gets handed in, then any in person class will involve a local, optional interpretive walk to the park (Trout Lake), again, rain or shine.
Common questions: May I use a computer in school library or computer lab?
All computer labs and library computers are closed. Please use your own device to access the internet at school. If you have access to a phone or tablet, you may use this.
Do I bring my own pens, pencil crayons and paper?
You are encouraged to bring your own pen, pencil crayons or felts as we have been advised by public health that students should not share writing materials. However, we can give you paper. We may do some sketching during class time so if you have your own sketchbook, you may bring it.
Is it mandatory to come to school? No it is not. School is OPTIONAL. If you come, I would be delighted to welcome you and help you with the plant ID app, but this is not mandatory. You can come for as much or as little biology class as you choose. If you do not come, I will continue to support your learning on-line.
Although you studied mitosis and meiosis last year, it is worth a look again to make sure you have all the steps down correctly. This video explains how alleles are connected to the steps of mitosis and meiosis. I also assume this is familiar from last year.
Please watch this video

Thanks for sharing questions. I will answer a few of them below
MORE QUESTIONS
Can a mom and dad alleles merge with each other? (for example, Heterochromia)
- your Mom and dad's alleles merge when you do meiosis. That is crossing over.
Why are DNA located in the nucleus?- for protection
How does a chromatid form as it is branching off the DNA strand? - chromatids wind up at the last
part of interphase in mitosis and meiosis.
How much chromatids or genes does one DNA strand produce? - one DNA strand makes one
chromatid
Is an Y Chromatid a piece of an normal chromatid? - a y chromatid is a part of a normal set of DNA in a human.
MUTATION QUESTIONS:
Gene mutations happen when DNA REPLICATION makes a mistake in copying the chromatin. DNA polymerase makes a mistake when your body is exposed to MUTAGENS. a MUTAGEN is anything that causes DNA to make mistakes during replication. For example, UV radiation, or X-rays or smoking, eating a diet heavy in preserved meats... all of these are linked to cancer. These are all EXTERNAL FORCES which cause mutation. Finally, they are discovering that even some viruses can also cause mutation. For example, the human papilloma virus can cause cervical cancer. That is why all of you got the vaccine for HPV when you were young.
CHROMATID AND ALLELE QUESTIONS
"Why does your nucleus contain only one chromatid?"

We can't be on site, but we can be together again in a virtual learning community! Please stay tuned here so that I can give you class assignments from my website. You will receive an email from your homeroom teacher at Gladstone. Please reply to that email!
We want to come together as a learning community again. I hope that you have the resources around you to be safe, to be fed, sheltered, to be at peace and to be connected with those who love and care for you.
If you need to contact anyone at the school, such as a counsellor or staff member, and you are not sure how to do that, please send me an email and I will try to connect you.
Take a blank sheet of paper and work with a partner. Think of an ANALOGY of a cell. For example, my analogy of a cell is...The cell is like a chocolate factory. And the office where they have the recipes for the chocolates is the nucleus. The door is the cell membrane. The assembly line where they make the chocolate is the endoplasmic reticulum. The furnace and the electricity providing heat and powerfor the factory is the mitochondria. If the factory has a solar panel, that's a chloroplast.
Come up with your own analogy.
Draw this analogy, and label it and also explain your analogy. Choose to make an analogy of a plant cell and an animal cell. staple your two papers together and hand it in. It must be in colour and in pen for 20 marks.
These are articles written by reporters who lived through the SARS outbreak. That coronavirus also came out of an animal market and that virus caused respiratory distress. These were the precautions that people took.
Today you will work on the concept of "Half Life" and you will be given a worksheet.
