SPECIES LIST

PLANTS vine maple, cedar, sitka spruce (mystery tree), sword fern, bracken fern, alder, red elderberry, salmonberry, skunk cabbage, horsetail, english ivy, 

DNA intro lesson

 Have a look at this introductory video on DNA.  DNA is a code, an alphabet.  Its alphabet has only 4 letters, and these 4 letters can create words, which make instructions for all of life.

In this lesson, you will learn the basic structure of DNA.  Have a look at my videos describing the nature of DNA

 

In the history of DNA, Watson and Crick and Franklin discovered the structure of DNA as a RIGHT HANDED HELIX!  It is quite the story of Scientific competition and ingenuity!  

I would like you to answer these questions:
In Microsoft Teams, I would like you to find your assignments for this DNA unit.


ASSIGNMENT 1 :  part 1 DRAW DNA
First, draw a labeled picture of DNA that summarizes the main points of DNA.  Photograph this cartoon in a clear picture and hand it in.  your NAME MUST BE CLEARLY WRITTEN ON CARTOON.

The main points are:

1.  DNA is made of nucleotides
2.  The nucleotides are made of sugar, phosphate and a nitrogen base
3.  The nucleotides join together in a ladder structure
4.  The ladder structure is antiparallel.

5.  There is complimentary base pairing

6.  DNA forms a RIGHT HANDED helix

your rubric
5 points:   your cartoon is brilliant, it includes all main points and it is in colour and inked YOUR NAME IS CLEARLY WRITTEN ON THE PAPER
3-4 :  your cartoon includes all main points and is complete.
1-2: your cartoon is incomplete.


ASSIGNMENT 2:  UPLOAD YOUR MODEL OF DNA which we constructed in class

5 points:  you upload your model WITH your MAPLE LEAF with your name on it.

in person assignment for both classes: Dead or Alive assignment for week of Tuesday, April 27

Today we will review what it means to be alive for an intro to biology. First, a look at our biosphere in the context of our universe.   

The definition of biosphere is the thin layer of soil, water and air and all the life that interacts within it

Next, we look at the living things on our school grounds. The app inaturalist is very useful to identify living things.  Tuesday and Wednesday you will explore what it is to be a living thing, and you will create a Naturalist Notebook using blank paper, your MAPLE LEAF and an iNaturalist app.   Today you will

1.  Do an exercise called "Dead or Alive"  Have a class discussion on the fundamental criteria of living things. 

2.  Download iNaturalist on  an electronic device (such as a phone).  

3.  Find living things in a natural place such as our Gladstone School Grounds, or Gladstone Garden. 

4.  Photograph living specimens (and upload to iNaturalist). IDENTIFY the specimen and create a document which shows the pictures you took with your MAPLE LEAF.

SAFETY PRECAUTIONS:   WHMIS: biohazardous, infectious disease 

At this time, the risk of covid-19 Brazilian variant P1 is high in Vancouver, especially if you are meeting people who are not in your immediate household.   This covid-19 variant of concern is more easily transmissible and can cause illness in young people.  Estimates are that in VCH more than 60% of positive covid tests are P1.   Therefore   we will conduct our lesson outdoors to mitigate this risk. You will keep your mask on when you are within 2m of another person outside and you will wash your hands if you share any maretials today, including pencil crayons.

ASSIGNMNENT A AND B 

ASSIGNMENT A:  SCAVENGER HUNT WITH your MAPLE LEAF: DEAD OR ALIVE?   ( 5 marks ) 

1.  Find something dead:  How do you know it is dead? (1 mark)

2. Find something alive.  What are the characteristics that tell you that this thing is alive? (1 mark)

3.  Find something that has never been alive.  What characteristics tell you that this is a NONLIVING thing.  (1 mark). 

4.  Discuss together, as a class,  what are the fundamental criteria of living things.  There is no wrong answer here...  Write these criteria in a paragraph.   (2 marks). 

What are the Criteria for Living things? look at these notes which we took today

ASSIGNMENT B: SCAVENGER HUNT WITH YOUR MAPLE LEAF WHICH HAS YOUR NAME ON IT.

(5 marks). 

FIND THE FOLLOWING SPECIMENS ALL ON SCHOOL GROUNDS:

5 different plants 

5 different animals (this can be INSECTS, SPIDERS, PILLBUGS)

2  fungi ( if you cannot find a mushroom, this can be lichen, which can be found on tree bark)

Include pics of your specimens under the microscope 

UPLOAD YOUR PHOTOS ON A WORD DOCUMENT OR PDF 

*If you are currently working from home, try to find these specimens in a garden

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 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

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 your Quadmester, I would like to prepare for learning during the third wave of Covid 19, including transmission of covid variants.   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:

- 15 students in every class.   

- physical distance, as much as possible

- wear a mask! It is required  (if you have medical reasons for not wearing a mask, please have your guardian inform me) 

- no academic penalties for being home sick, for isolating or for a +ive diagnosis of covid-19 either in yourself or a household member.

- 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. 

- for Quadmester 4, in May, I will hold many science classes outdoors for the first few weeks so that all those who are over 40 (many of your parents and guardians) may access vaccines before we do more indoor learning, in June.  

Cases are very high especially in our neighbourhood.  case per 100 000 is 257 and this means 1 out of every 500 people in the Kensington neighbourhood is +ive for covid 19 in the last few weeks. I am determined to reduce any exposure risk in my classroom by holding class in the school garden or school grounds.  Dress accordingly with hat or sunglasses or rain jacket if we are to take a walk.

What colour is that dress?

There is a very interesting dress. It has caused major arguments!  This dress causes your cells in your retinas to perceive it to be certain colours depending on the state of your retinas. Of course your genes determine what your retinas are like...but also your retinas change over time too!  

Your perception is also based on whether you think this dress is in shadow or light...Try this, 

 I would like you to ask  20 people you know "What colours do you see on this dress:  Is it :  

A. GOLD AND WHITE 

B.  BLACK AND BLUE

C.  GOLD AND BLUE

D.  NONE OF THE ABOVE...THEN what colour is it?  

What are the characteristics of the people who are more likely to say that it is any of the choices above?   

Remember you can poll people without meeting face to face. Ask a variety of people including old, young, male, female...put your results on a table and hypothesize why people see different colours
