Rates of Reaction lab

   Read the following notes

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

You will be doing a simple two beaker experiment to observe rates of reaction.

Types of Reactions

I am absent today due to unexpected illness.  Our Dry Ice Lab  is therefore postponed to Thursday.  Please open the windows and turn on the fans on low for ventilation.

Today, you will learn about the different types of reaction and review these types with the teacher.  

This is  a study guide and notes for different types of reactions   You will work on this today.  

Here are some practice problems  to work on today.     If you did not get the sheets in class you can do those problems to practice.  This material and the study guide questions will be on this friday's quiz. 

TEAMS ASSIGNMENT: 

For 10 marks, make a lego model of each type of reaction.  Label your lego reactions and photograph it with your maple leaf.    If you are working from home, use any material you have on hand to create the models.  

TEACHING NOTES:

First lets review the main types of reactions: 

Chemical reactions may be categorized as follows : 

1.     Synthesis

2.     Decomposition

3.     Single replacement

4.     Double replacement

5.     Combustion

       Cellular Respiration

6.     Oxidation of metals

A Synthesis reaction:

element     +   element    -->    compound

Decomposition reaction:

Compound    -->   element     +     element

Or

Compound --> smaller compound    +   element

DOUBLE REPLACEMENT


single replacement

IN ADDITION TO THE FOUR TYPES ABOVE, THERE ARE ALSO THREE MORE KINDS of reaction TO KNOW: 

Combustion:  combustion may happen to any *organic compound* meaning any compound made of carbon, hydrogen and/or oxygen...

Carbon based compound+ oxygen --> carbon dioxide + water

+ heat and light energy

Cell respiration looks like combustion,

BUT IT IS NOT. YOUR CELLS ARE NOT COMBUSTING.  The carbon based compound in this case is glucose, a simple sugar.

Glucose +   oxygen -->  carbon dioxide + water + energy for cell

Oxidation reaction

Metal +  oxygen   -->   metal oxide

ACID BASE REACTIONS ARE ALL NEUTRALIZATION REACTIONS

In summary....

Found a bushtit nest and I would like to do an investigation with it.

 

FYI if you are working from home, I will upload clear pictures of the bushtit nest here on this blog and on TEAMS, so you may do this assignment.

Investigation:  Write a report as a two page document or slide show. 

1.  a.  Here is some info on  Bushtit biology right here:  an excerpt from the website:

"Bushtits need to eat 80% of their body weight each day to keep up with their speedy metabolisms when weather is warm- they eat even more when it cools down. According to a study from 1907, bushtits in California had diets that consisted of 81% insect matter through most of the year, and which increased to 100% insect matter in the spring. "  

http://wildfarms.weebly.com/blog/bushtit-fluffy-insect-eating-swingers

write 10 points which characterize bushtit biology

1.b.  Observe the nest that was found and draw it.  

Take clear pictures of sections of this nest and try to identify what was used to make the nest. What do you think was used to construct this nest?  

2.  NEST SAMPLE (shared microscope) : Observe the tiny sample of the nest under the microscope and report what you see.  Can you see the spider silk?  The moss?  feathers?  Take a picture with your camera if you can.

3.  COLLECT YOUR OWN SAMPLE OF a similar species of MOSS and LICHEN  that is NOT from the nest  from outside and examine this magnified either under the microscope ( OR using your camera to take a really close shot )  and draw your sample.  Answer this question: What properties of moss make it suitable for nesting material? 

4.  Listen for the sound of a bushtit around our school.  Observe for bushtits over a few days.  Draw a map of where and when you hear this sound and include it in the report.   

The sound can be found in this video here

5.  Optional extra observations:  Some of you began looking at other interesting specimens in our class and using our microscopes.  If you looked at other specimens and photographed them, include them here too.  If you did not, no worries, number 5 is optional.

Evaluation

17-20 - This is a beautifully presented assignment with clear observations, photos, drawings and observations.  It is insightful and excellently done. It is typed or written in ink and in colour

13-16 - This assignment is complete and very well done with great photos and observations. It is in pencil

5- 12 - This is a good start with some good observations but it is incomplete

Greek Naming System for nonmetal compounds

 Learn how to write formula and compounds of nonmetals in my  video lesson below

Liver anyone? Today you made a Raw Liver Latte...

 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

Balancing equations worksheet

 

We did a worksheet practicing balancing equations and also modeled it with lego!  

Here is the worksheet and here is the answer key to the front side of it.

Ecological Scavenger Hunt Activity for Wed. May 12

I observed this (native species)  Douglas Squirrel in Capilano Suspension Bridge park. It is a herbivore eating Douglas fir cones but it was also begging for food. 

Today you will do a scavenger hunt activity.  Make a document, pdf or powerpoint to upload onto TEAMS and this document must have an example of the following WITH YOUR MAPLE LEAF with your name (or a piece of paper with your name if you don't have your maple leaf. )  If the pic doesn't have your name then you lose a mark.  

note that class sessions will do this in class.  And Flex blocks will do this on their own time during flex!  

You will get 2 marks for each item:  

Go to a park (such as Trout Lake) and for one mark, find an example of the following For your second mark, explain what you found in a sentence.   If you are doing this work from home, you may easily do this in a garden or yard!  

1.  Take a beautiful landscape picture of your site with your team members in it. 

2.  Take a picture of 3 trees Use iNaturalist to identify these using the leaves

3.  Take a picture of one animal that eats plants (herbivore).  Can be a bug or a worm

4.  animal that eats herbivores. (Can be a bird)

5.   one animal that eats animals that eat herbivores, a top predator, or evidence that it lives there...coyote hair, owl poo, etc. 

6. Take a picture of COMMENSALISM

7.  Find an animal in its NICHE and take a picture.  

8.  Find an example of PARASITISM

9. Find animals or plants that appear to be COMPETING for something (if it is an animal, it competes for food, prey, mates, territory...if it is a plant, it might compete for light, water, space etc)

10.  find an animal, plant or fungus in its HABITAT. 

Evaluation:  

18-20/20        This is an excellent compilation of ecological interactions!  Every item has a clear pic with your name (on a maple leaf) or a team member, or a paper with your name on it.  And a sentence EXPLAINING how your picture illustrates the ecological concept.  Your explanation makes sense and is logical. 

13-17   Every item has a clear pic with your name (on a maple leaf) or a team member, or a paper with your name on it.  And a sentence EXPLAINING how your picture illustrates the ecological concept.  Your explanation needs a little more evidence to be convincing but you have amazing pictures! 

5-12     You have a pretty good start on this and the pics are great but you did not include your name or team members in EACH photo or you are missing the explanation. 

Introduction to Chemistry

How does a linear code get translated into 3-d objects?

 DNA gets transcribed into mRNA which is given to the ribosome. This ribosome constructs a chain of amino acids, like a string of pearls. Some pearls are attracted to one another, others repel...And the pearls begin to move , to fold like molecular origami until it becomes a critical life protein:

enzymes

hemoglobin

keratin for hair, for feathers. 

pigment for photosynthesis

All of life's proteins have a specific order of amino acids, dictated by the sequence of RNA, which comes from the sequence of DNA.
