FOSSIL LAB

  We will go over these slides on GEOLOGICAL TIME

And this is some background info on how fossils are formed. please do this worksheet    using the link here for finding the answers. 

HERE IS A SECOND LINK

This is 10 marks

Geological Time Lab

USE THE DRAWING PAPER AND MAKE COLOUR AND INK DRAWINGS OF SPECIMENS

Station 1 . ROW 1 THREE drawings  

Draw TWO samples of SANDSTONE 

DRAW ONE SAMPLE OF SHALE

  Answer the following questions
1.  How is sandstone formed?  Explain how a fossil might be formed in Sandstone
2.  How is shale  formed?  Explain how a fossil can form in shale

Station 2.  Known Fossils  THREE DRAWINGS 
A.  COMPARATIVE TEACHING COLLECTION ROW 2
Photograph all  fossils summarize their descriptions 

MAKE ONE DRAWING which includes  one fossil and one modern day equivalent.   Label the drawings with the descriptions shown

B.  FOSSIL BOX and fossil bucket.  ROW 3   Identify 7 and MAKE TWO DRAWINGS

1. photograph  7 fossils from this box and identify them.

2. Make two drawings consisting of: 

a.  a careful drawing of ONE FOSSIL from the box.

b. a drawing of the actual organism that  it came from using an internet search.  

c.   Tell me what era it came from as well as its environmental conditions.  for example, if your fossil is a SHARK TOOTH, then the organism it comes from is a SHARK and it's environment is marine. So your drawing in section 2B b is a drawing of a shark in its marine environment.

Station 3. ROW 4  UNKNOWN FOSSILS. 3 DRAWINGS 

 Choose 3 to draw
CHOOSE 3 fossils to identify.  photograph them and give evidence that you can identify the fossil using the known fossils. 

EVALUATION.   60 marks total

lab portion total 60 marks 

50-60 marks - you photograph all the fossils and you make drawings 

 3 drawings for station 1

3 drawings for station 2 and 

3 drawings for station 3. 

 You complete all your observations.    

30-45 - you completed all the drawings and it is not in colour .  Your drawings look great.  Or, you have beautiful drawings but did not complete all the drawings for each station.  

10-30 - This looks great and you need to complete the work

0-9 - this work is incomplete. 

KERATIN ADAPTATIONS

 

 Open the windows for ventilation during this lab. 

Note: these feathers were collected prior to 2018

DNA forms the recipes for many adaptations in kingdom Animalia.  One example of a common recipe used for different purposes is keratin.  Keratin is a protein formed by a sequence of amino acids dictated by DNA.  

Keratin forms the hair of primates, canines, felines, all mammals.  Keratin also forms the scales of a fish, the feathers on a bird.  The soft keratin in birds and mammals is called alpha keratin. The harder keratin on a fish or a reptile is called beta keratin. 

This website explains the difference

The Science of Birds

Examine the variety of forms in the feather samples in the lab.  Look at these under the dissecting microscope.  Wash your hands after handling these feathers and note that all feathers are part of a collection that was assembled prior to 2018 and thus unexposed to current avian flu outbreaks in the lower mainland

Draw 3 samples of feather and answer the following questions: Each drawing ought to be half a page.

1.  Which  feathers look like they are good for insulation? These areas would be soft and fine, with the ability to trap air pockets

2.  Which feathers look like they might be good for catching wind for gliding or flying?  These feathers can zip together and come apart alike a zipper.  

3.  What are the differences that you can observe on these feathers? How are the feathers different in shape, texture, colour?  What is the purpose of colour for a bird? How can colour on a bird feather help a bird survive in the wild?

Examine the Fish Scale under the microscope:  Draw two views. Each drawing ought to be half a page.

1.  What is the purpose of the fish scale? How can this scale protect the fish? 

2.  Some scales are iridescent or they catch light in different ways.  Adjust the light levels under the microscope  and see what  you can find for interesting perspectives on this piece of fish anatomy. 

How Evolutionary Change occurs

 review these intro notes on evolution,   If time, look at the notes on

How evolutionary change occurs

Watch the videos below on speciation

BE PREPARED FOR A QUIZ ON THIS COMING UP

ASSIGNMENT

DO TWO TASKS
1. WRITE A SUMMARY OF HOW SPECIATION OCCURS, WITH ILLUSTRATIONS.
Review THE BIRD video on the steps of speciation and take notes on this, outlining the steps. Also read "How evolutionary change occurs" as a reference
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:

xʷməm̓qʷe:m Camosun bog

  Take a look at  my  BOG PRESENTATION 

Camosun Bog Restoration Group method for bog restoration:  Watch this video. The teens in this video are my students when I taught at PW.  They learned their plantae unit by joining a work party!  You can also read about the history of camosun bog restoration here.

 https://www.youtube.com/watch?v=SSrEhGSnhiY

Why  xʷməm̓qʷe:m, Camosun bog , is important: Listen to  Elder Larry Grant talk about  xʷməm̓qʷe:m.  By the way, Elder, Larry Grant's parents are Musqeuam and  Chinese.  In addition to being a speaker of the Musqueam language, he understands and speaks Cantonese.

https://www.youtube.com/watch?v=v6K7jASVzl8

Watch Elder Larry Grant's personal story:  He is a language keeper of the Musqueam People.

Watch the creation story of the Musqueam people . Their story begins  in Camosun bog.

The double headed serpent story 

 The Double-Headed Serpent from Deadpixel on Vimeo.

This is a pole carved by a Musqueam artist and related to the fourth video above.  It is  located in UBC and this is what it means 

Transcript of Elder Larry Grant video:

The bog is an integral part of Musqueam. In Musqueam history and the story of Musqueam. So that real connection. When that bog, it’s quite a few things actually when the bog shrinks, that means that people have drained the bog. For urbanization and use of land, removing what western culture called unusable land or unusable space, for I would say non cultural well, to us, non-cultural activity to the Musqueam people. Why would you drain a bog, it carries so much life, if it’s drained it’s allowed to shrink even more. That actually erases all the corroborating evidence of the story of Musqueam and it’s eradicating cultural identity, Aboriginal identity, it’s eradicating Aboriginal identity, in that sense where it removes all traces of any of the stories that we will be able to tell or we can still tell the story, but we won’t be able to say that this is where it originates. And if it’s completely drained, that’s just another step in removing all traces of First Nations People. I would like to see it grow actually but that takes a lot of effort, I would like to see it open up a little more and all those Indigenous plants that are there, allowed to expand a bit because then it becomes a teaching tool for all people. About the value of the bog, the biodiversity that’s in there is amazing, yeah, and it’s set up where people can walk though there and have a look and get very close to all the plants and the mallard ducks are still there. They sit in that center pond and just live be around up there and actually be part of the story of Musqueam. There is a mallard duck in there, there’s actually a little family of mallard ducks in there so.
