You will try to solve this problem for our Half Life Exam

 The year is 2050 and the president of the USA (Ivanka Trump)  has just fired a missile at Vancouver.  This international incident draws a stern warning from the United Nations.  The missile lands on a grocery store located here:

The missile makes a huge crater 50 ft deep and in the rubble, you notice there are layers of shells. Amongst the shells there is the mystery specimen which I have shown you in class.  

Questions: 

1. What is the likely identity of the object?

2.  Where did it come from?

3.  How old is this sample?  It contains 78% of the ng of Carbon-14 compared to any living sample 

4.  What First Nations Territory is this area of the lower mainland?  

5.  How might this sample have ended up here? 

When you answer these questions, give the EVIDENCE for your answers. 

Answer this question in form of a word document or a power point. You may work in a group. Please put references as the last page of your assignment. 

55-60/60

You answer the questions in paragraph form with illustrations (photos or drawings). Your reasoning is logical. You provide evidence for your conclusions.  You write clearly and your argument is communicated well.

40-55/60

You answer the questions in paragraph form with illustrations (photos or drawings). Your reasoning is logical. You provide evidence for your conclusions.  Your argument is good and could use a little more evidence

35-40

You answer the questions in sentences and you have photos and drawings. You provide little evidence for your conclusions

0-30

This is an excellent start, but you need more time to complete this project.

Catch up on your labs or do 7.1, 7.2,7.3 today

You may work on your lab assignment or the electromagnetic assignment from yesterday.  If you finish, you may start the  7.1 worksheet, which the teacher may find on my desk. .   Read and do the 7.1 worksheet on ALPHA, BETA and GAMMA decay.  Here is the answer key

Electromagnetic Scavenger Hunt

 Today we learned about the electromagnetic spectrum.  Within your group, find the following & take a picture with a sign labeling what you found. Put this together in a power point and hand it in through TEAMS.  YOUR PIC MUST HAVE THE SIGN IN IT!!

First block 

1.  A wave slower than infrared waves and faster than radio waves 

2.   Living things that have 7 colours of the visible spectrum (Can be 7 people) 

3.   Americium

4.   Someone who got radiation *on purpose * 

Second block  

1.  a radioactive food

2.   Something that makes  a wave slower than infrared wave and which can transmit images and sound

3.   Someone who has had radiation on purpose & the radiation has a faster wavelength than UV

4.   Someone with something that *filters* UV light 

5.  Something that makes waves that are faster than infrared, slower than radio waves 

6.  Americium 

Naming Acids

 Today we reviewed naming acids and I asked you to write  "...ide" acids and    "...ite " acids and also    "...ate" acids. also you did an exercise in naming acids last block.  

Now you can do the naming acids practice on PAGE 18  in the Chemistry practice sheet Here is the Chemistry practice sheet key.

Universal Indicator Rainbows

We used universal indicator, a known acid and a known base to create as many pHs as possible. 

Purpose: To create as many different colours as possible for pH

Materials: Vinegar, Water, NaOH

Procedure: Write down your step by step procedure for creating the different colours. 

Observations

 

Write some observations for your lab. What happened when you mixed liquid in a certain order? How did your group manage to achieve different colours from only 3 colours. 

Using your photos of your lab, indicate the pH of all the different colours.

Conclusion: Write a paragraph describing what you learned. Explain how this lab demonstrates the pH scale.  

EVALUATION   IS OUT OF 25 IN TOTAL and you may work in a group of two or three

5

presentation is out of 5.  for 5/5 it is typed  with illustrations or photos and emailed to msngscience@gmail.com.     for 4/5 it is pretty good but there are a few spelling mistakes.  for 0-3 out of 5 it is in pencil or messy.  I prefer this to be printed

10

Clear writing is out of 10.  for 9/10 or 10/10, it is written with no English mistakes and it clearly communicates each part of the lab report.    7-8/10  it is very well written     for 5-6/10 some parts are not so clear and the reader must guess what you are trying to say.  0-4/10, it is minimally communicating what happened

10

Paragraphs are insightful and your observations are well done. this is out of 10.

             9-10/10,   your observations and conclusions are well written and logical.  It is brilliant

              7-8/10   your observations and conclusions are very well done

               5-6   your conclusions don't really logically follow from your results

                0-4   your conclusions are not relating to your results at all
