Modeling Atoms, Elements, Compounds

 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:

The Nature of Sound

 Sound is a mechanical wave, a longitudinal wave...Today we explored the nature of sound by reading a printout of this information from this website 

Sound is a Pressure Wave 

Assignment: 

Write notes on this website and get ready for a quiz on this material. Write a one page summary. 

Also, on the same page, write OBSERVATIONS on observing  a longitudinal wave using slinkies provided in class .  write your observations. 

5 marks 

We also tested our hearing in class. How old are your ears? 

Can you hear these frequencies?

Answer the following questions: 

1. Copy the data table

2. Notice that the numbers are not identical. Identify at least 3 factors that account for these differences

3. Which column shows the most variation? L,W, or H? Why?

4. Which numbers are most likely to be true? Explain

5. How would you reduce the error? 

Measurement activity

 Find the length, width and height of our science classroom. 

Find the mass of a large chair

Write a data table on the measurements. 

Safety scavenger hunt: Find the following materials and put it on a map

1. draw a map of the class

2. label the following

a. fire safety

b. eye wash

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

Science 9 safety part 2

 

Dear Students,

As I welcome you back to school in the midst of our 5th wave of Covid-19, I would like to review our safety rules in class:  Community prevelance of Covid is extremely high right now, so you  must assume you will be exposed to Omicron when you return to school. There is no vaccine mandate at school so there is no way of knowing who is at higher or lower risk. Further there is no more contact tracing so we have no idea who is infected and who is not.  

 

The following safety precautions will be made to mitigate the risk from this exposure:

1.  Windows open at all times in my class while I supervise the class. Dress warmly! 

2.  Outdoor activities are  being planned for the remainder of the semester.

3.  Students are NOT to attend school sick. There will be NO ACADEMIC CONSEQUENCES for absence in my class. If you email me to say you are not feeling well and will be home, I will mark you absent, and will excuse your absence. Further if you feel more comfortable learning from home, please contact me and I will be flexible for you.

4.  I STRONGLY RECOMMEND NO EATING INDOORS as this is where the exposure is most likely to occur. If you eat  OUTDOORS, it is much safer and will help reduce the chance of getting sick and missing school. 

5. I STRONGLY RECOMMEND upgrading your mask to N95 if possible. The black VSB masks given out were washable K95s.  These masks need to be tightly fitted on your face 

6. While students of any vaccine status is very welcome in my class,  I STRONGLY RECOMMEND making sure you are fully vaccinated and you access the booster shot as soon as possible. This step will enhance safety at our school. 

I am commited to airborne precautions in my class.   This means walks to Trout Lake, to the forest in Central Park, to the Renfrew Ravine to do ecological activities.  It means doing in class labs in cold wintry conditions .  We can try our best to  beat Omicron and have fun doing it!  

ASSIGNMENTS 

 We will be spending some time on LOCAL FIELD STUDY in the month of January to end the semester!  Please have a look at the field study form which you will need to hand in SIGNED by your parent or guardian. this form is due on Tuesday for 5 marks.  

I would also like you to design a safety poster (can be digital or on paper) which summarizes the main points of this important paper written by academics and doctors.  TRY TO ILLUSTRATE THIS with as FEW WORDS as possible.  It can be in a variety of creative formats such as A COMIC, a POSTER, a RAP or POEM, illustrated, a PODCAST or recording of a public safety announcement.

The best of these assignments will be shared with professionals with credit to you.  If they use it as part of a pandemic safety campaign, you may put that on your resume or portfolio!  20 marks

20 - This stands out in its effort and creativity. 
18-19. This is done in ink and colour and includes all the details above and the details are all correct.  This is excellent

15-17. This is very good work with effort and correct details.  Some details are not there but most are there and there is excellent quality of drawing and presentation.

10-14. This is a very good start and your work shows creativity.  It is not in colour or ink and looks like a very nice draft

5-9.  This is incomplete but a decent start.
