how evolutionary change occurs

  WRITE A SUMMARY OF HOW SPECIATION OCCURS, WITH ILLUSTRATIONS.

 review these intro notes on evolution,  and read the notes on

How evolutionary change occurs

Review THE BIRD video on the steps of speciation and take notes on this, outlining the steps. 
2.  NEXT, write a summary of the human evolution video

Evolution Introduction

 Take a look at the Evolution power point and do the lab exercise at the end:

BIRD NEST lab

  

This bushtit nest is extremely fragile. It was collected from a Vancouver sidewalk more than 5 years ago prior to the outbreak of  the current mammalian variant of highly pathogenic avian flu.  Also Flu viruses are not viable for the time that has elapsed.  It is not advisable at this time to collect any bird nests due to potential exposure to HPAI.  

Do not take it out of its container.  Instead, use the petri dishes which contain parts of this nest to answer the questions.  

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  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. "

write 10 points which characterize bushtit biology

1.  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.

2.  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? 

3.  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.   

4.  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 4 is optional.

Evaluation GROUP ACTIVITY 

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

NOTES ON CLASSIFICATION

 Read these notes on classification

please correct the following in these notes:   the notes show the old classification. today the new classification is:

Kingdoms archaea , bacteria  (formerly monera ) and eukarya 

and under the eukarya kingdoms kingdom animalia, fungi and plantae 

Answer these questions 

1.  What is classification?  Who invented it?
2. Explain the term binomial nomenclature
3.  What are the taxons of life, in order of largest to smallest?
4.  Define species.
5.  Cell respiration is a universal energy equation.  Where does it happen?  Write the equation.
6.  What is ATP, ADP.  Give an analogy for how this works
7.  Define Heterotroph and Autotroph
8.   ACCORDING TO THESE NOTES, What is the definition of
a. Animal
b. plant
c. Fungus
d. Protozoa
e. Monera

Hey Eu! Eukaryotes vs Prokaryotes

 watch this intro video on Eukaryotes and Prokaryotes

This video is an intro to some of the similarities and differences between eukaryotes and prokaryotes. It is meant to accompany our class notes.

Vocabulary words and ideas in the video:

Eukaryote Prokaryote DNA nuclear membrane protozoan multicellular organisms unicellular organisms cell membrane, cytoplasm, DNA, RNA, ribosome, protein, endoplasmic reticulum vacuole mitochondria Plant cell chloroplast cell wall made of cellulose cell wall made of peptidoglycan Bacteria in the environment and the gut

MAKE a model of the cell out of lego: Make one eukaryotic cell and one prokaryotic cell
 Make a creative summary of these notes.  The summary must cover all of the points below:

 1. What are the 4 criteria to life? 

2. What are the two main types of cells on earth? 

 3. Give an example of a. UNICELLULAR organism b. MULTICELLULAR organism 

4. I gave an example of the cell as a chocolate factory. Make your own analogy of the cell and include EVERY ORGANELLE. You may choose a plant cell or an animal cell.

 5. How are plant cells different from animal cells?

 6. What are four ways that cells can interact with each other. below

evaluation: 20 points

Classification Activity

 1.  Read 196-199 in the Biology Textbook

and make point form notes on these pages, copying fig 7.2 an 7.3. Write all the definitions of words in bold: binomial nomenclature, species, dichotomous key, Taxa, phylogeny.

2.  Examine all the specimens in class

a. draw the specimen using a half page per drawing

b. Identify the Kingdom or phylum and include as many taxons as possible

c. What are the adaptations? 

d. What is your evidence for your answer for b?
