Patterns on the Periodic Table:

 The Periodic Table is a list of all the elements in the universe. Here are some patterns that you ought to know. Take notes on this lesson

ASSIGNMENT: 

on the Periodic Table provided, colour code the following:

METALS

NONMETALS

NOBLE GASES

ALKALI METALS

ALKALI EARTH METALS

TRANSITION METALS

label the ionic charges of the families. photograph your work SUBMIT TO TEAMS 

Atom Element Compound

  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 : 

practice making a model of ATOM, ELEMENT, COMPOUND, MIXTURE  and label it. practice making lego formulae.  Take a picture of the lego formulae you did in class

We will learn the analogy of LEGO and  practice building lego compounds, and writing lego formulae.

Make as many combinations of compounds as you can with the boxes of lego provided

Take a picture of the work you did in class

Examples:

Work on Safety assignment

 Today and tomorrow you will work on our Science Safety Assignment

or, finish up your filter fan

Create a pamphlet for your box fan filter

 Using one page, Write the following facts on your pamphlet:

1.  Climate change causes wildfire smoke and PM 2.5 is very unhealthy

2. Hepa filters in classrooms reduce particulates by 48%

3. Hepa filters in classrooms reduce ABSENCES due to illness from flu, covid, RSV 

4.  Draw a picture to show how bad air enters your fan and clean air exits

Welcome to Science Class

  Welcome to Science 10! 

This course is a lab course which will cover Chemistry, Physics, and Biology   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 as paper assignments or 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.  

ASSIGNMENT 1. HAND IN YOUR CONSENT FORM  /5

Please get the consent form signed and bring it back to class. It will give us the ability to walk to Trout Lake or Renfrew Ravine or go to a local field study 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 respiratory season of flu, RSV and covid 19.   

SAFETY MEASURES:

 In class, our safety measures will include:

- good ventilation. I will be using a CO2 monitor to check the air quality in our class. If this number goes above 800ppm CO2 then there is a 1% rebreathed fraction meaning that 1 breath out of 100 is from someone else's lungs. Beyond this point I will ask for volunteers to wear a mask so that my class remains accessible to those who are medically vulnterable

- wear a mask! It is encouraged because you will be an ally for those who are medically vulnerable or those who live with people who are vulnerable. 

- no academic penalties for being home sick, for isolating or for a +ive diagnosis of covid-19 either in yourself or a household member. You only need to email me to tell me of your positive test, and I will excuse you from homework.

- windows shall be open in my class to admit adequate ventilation.  Further we will conduct class outside wherever possible as outside is safer than inside at this time.  Dress for the weather and be prepared to be outdoors rain or shine. 

Science 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
                         SYSTEM 

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

THESE ARE MY SCIENCE SAFETY RULES:

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

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 

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
