Solid Carbon dioxide lab

 

Today you will do this solid carbon dioxide lab

Today we balanced equations

 here is the answer key

Red Wine or White wine?

  Today I invited you to a fancy French restaurant and served you "red wine or white wine"...

Do an experiment with four 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.

Going for a nature walk

Today we will meet promptly

 at the classroom at :

1035 for Flex A morning class

1215 for Flex B afternoon class

We will walk together to Trout Lake park.

You only need a camera. Bring the frog.

This is our proposed route.

      

Wednesday FLEX SCAVENGER HUNT: find the most interesting tree bark and take a picture of it.

We think of ecosystems as being big places like a rainforest, or a desert.  But did you know that there are micro ecosystems, little tiny habitats that are filled with living things!  Even tree bark can have lots of interesting things growing on it!  For today's assignment, GO OUTSIDE. Find the most interesting tree bark picture and place your frog on it.  Your picture should have LOTS OF LIVING THINGS such as moss or lichen or mushrooms or  little bugs etc.  It might have SIGNS OF LIVING THINGS... The more living things a habitat has, the healthier the ecosystem. 

written observations: Tell us where you found this picture and what drew you to this particular tree bark.  Tell us how many different kinds of living things you can see on this tree bark.  Tell us where you took your pic, whether your tree was evergreen or deciduous and also what sounds of animals you heard, if any.  

UPLOAD YOUR PICS between 11 and 12 today!  

Here is an example.   I found this tree bark in Central Park. It has lichen (light grey green upper left), moss, and a little bush growing out of it.  The holes were made by woodpecker, which ate the bugs living there.  The white stuff is left by an owl.  When I took this picture, I heard chickadees.  

TEAMS ASSIGNMENT:

upload your OWN PICTURE and words.  And look at ALL THE PICTURES.  What were the most common living things mentioned by the whole class?

Liver anyone? Today you made a RAW LIVER LATTE as our lab in class!

 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.  

In today's lab, we discover the new products

There are four ways to increase rate of reaction. You will do some simple home experiments to illustrate some of these points

 Read the following notes

Assignment : Do the study questions, put your name on it and photograph it.   Answer key is here.

I gave you a Nomenclature practice sheet!

Here are the nomenclature videos again

 

Assignment:

 Nomenclature practice sheet. Do these practice sheets for 5 marks

Why are we opening windows when it is so cold?

 The 1912 TB epidemic threatened to close schools because TB causes pneumonia. Open air schools were created in New York to stop the spread of infectious disease.  According to the BCCDC school guidance, the same methods work against covid 19. An open window can dilute the virus, keeping us all safe.  Take a look back in time: there were pupils dressed just like you! in winter clothes in their school classroom!   Pictures from this NYT article on how to beat a pandemic with fresh air! 

Ionic bonding and the game of compound

Ionic bonding

 Make a deck of cards for yourself and play the game of compound!

Safety

  Now we are doing a unit on safety. Please do the reading, the homework and MAKE A POSTER SHOWING   SUMMARY OF ALL THE RULES

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

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. PLEASE EDIT THE FORM TO PERTAIN TO YOUR QUADMESTER 

evaluation:  5 points for handing this in

As we go into your Quadmester, 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
