Welcome to Science 10

  Welcome to Science 10! 

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.

Science Safety Rules

 MAKE A POSTER SHOWING   SUMMARY OF ALL THE RULES

1. 
































                         WHMIS -  WORKPLACE HAZARDOUS 

                         MATERIALS INFORMATION
                         SYSTEM 

      THESE symbols are on the MSDS sheet for
       all chemicals    Materials safety Data Sheet. 

1. Follow teacher instructions
a.     If you wish to change instructions, check with teacher
b.     If you break anything or get hurt, report it REPORT ACCIDENTS

2.     No horseplay, fooling around
3.     Keep yourself safe
a.     Hair tied back, no loose clothing, shoes are closed
b.     If chemicals get on skin, use water
c.     Use eyewash if anything gets in eyes
d.     Wear goggles if needed
e.  If you wear contacts, inform the teacher

4.      Keep your area safe
a.     your work area is neat and organized
b.     you have your lab instructions
c.     aware of fire safety and chemical safety

5.     Keep the classroom safe
a.     Carry materials in a safe way
b.     Aware of fire safety procedure
c.     Don’t remove any experiments from the classroom
d.     Don’t do experiments without first checking with teacher.


6.      Hot and cold and chemical safety
a.     never assume the temperature of something.  Take precautions
b.     hot beaker and cold beaker look identical
c.     always point a test tube away from everyone
d.     when smelling a chemical, waft.

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. 

  Further include the WHMIS SYMBOLS

The Language of Motion

 Today we learned about the definition of the following words.  There is also a worksheet for 

which this is the answer key.  upload your pics of this with your maple leaf for 5 points

scalar

vector

motion

distance

displacement

We also took video of longboarding in the tennis court. 

Physics Assignment:  Longboarding data

Upload your data table and your position time graph of motion along the number line in the tennis court.

5 points 

your group member uploaded the video, you made a correct graph with the x axis labeled position and the y axis labeled timeit includes your data table.

Bohr Diagrams and Lewis Diagrams

  

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

Create covalent bonds by joining unpaired electrons


We are very pleased to welcome scientists in our class today

 Dr. Pascal Lavoie and Lauren Muttucomaroe will be joining us to present their research on covid-19 transmission in VSB schools.  Link to there study is below. We are very grateful they met our students today.

Your teams assignment is to create a one pager summarizing what you learned and upload that onto TEAMS. (5 marks)

Plants have defenses too!

 We have been learning about the immune system in class to get ready to meet a UBC researcher who studies immunology.  Did you know that plants have defenses too against herbivory?  Some of these defenses are chemical and some are physical.


Foxglove, or digitalis contains toxic chemicals which include cardiac glycosides.  

plants evolved defenses when the first sign of herbivory occurred in evolutionary history. 

Some of these are chemical defenses in the form of poisons. In fact many drugs are derived from plant poisons.  Digitalis is a drug derived from the flower foxglove.   The seed of an apple contains a small amount of  cyanogenic glycoside:  cyanide.  

Plants which contain volatile organic compounds are often very aromatic.  Thyme, Oregano, Rosemary and Lavender are plants which have alot of volatile organic molecules. Not all VOCs are used for herbivory defense.  Some plants use VOCs to attract pollinators. 

Pieris Japonica contains grayanotoxins I, II, III (polyhydroxylated diterpenes) which can cause arrythmias, seizures, vomitting.  



Spines, thorns and hairs also discourage herbivory even silica on horsetails. 






Scavenger hunt 

Take a picture (with your name in it) of the following specimens found in our school grounds:
1.  Foxglove, or Digitalis 
2.   A thorny stem
3.  Hairy leaves
4.  Horsetail. (look at the silica under the microscope).  
5. Lavendula stoechus. (lavender, which has volatile organic compounds)
6.  Pieris Japonica (there is only one specimen I know of on school grounds.

A.  Read and create a ONE PAGE visual summary of the main points of the resources below.  (a one page summary showing main points of ALL the resources below.

B.  Generate 5 questions from each of the 5 topics below:  (5 topics = 25 questions). 


1. SCHOOL TRANSMISSION:  What are the risks of covid transmission in schools and what mitigation measures are effective in schools?  What factors in schools can spread covid?  Read this review and write 5 questions:
