Calcium demo and lab report

 Assignment:   Write up our lab on Calcium and water. 

image by Katelyn M

 Your lab must include the following

1.  First and Last names of all investigators

2. Purpose of lab:  The purpose of the lab is to find out what happens when you add calcium to water.  Describe the teacher demo that preceded this lab. 

3.a Materials: write a complete list of materials that we used including the litmus paper at the end.

b.  Safety:  list the safety precautions for this lab

4. Procedure: Draw a cartoon to describe the step by step procedure  that is so well written that another person could read it and replicate your actions exactly. You may also upload pics demonstrating your procedure.

5.  What is the question we are trying to answer?  For example there were two possible gases that came out of this reaction.  What gases were they?

6. Results:  Describe in detail what happened after you did the procedure.  Include any photos you took.  How did you know you made the gas, which gas?  

7.  What was the white stuff?  How did you test for the identity of the white stuff? 

8. Write your conclusion in paragraph form.  


EVALUATION   IS OUT OF 25 IN TOTAL

5
presentation is out of 5.  for 5/5 it is typed  with illustrations or photos and handed in electronically or on paper

     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
      

ACKNOWLEDGEMENTS
write all names and who contributed what including the % of their contribution. so two people who contributed equally would be50%

Writing Ionic Compounds

Review the rules of writing compounds.  

 Nomenclature practice sheet. Do these practice sheets for 5 marks 

Answer key is here 

The Game of Compound

I asked you to make a deck of compound cards using the list of Common Ions which I gave to you in class.   Don't just make one of each card, make lots of repeat cards of the same ion so that the deck can be used to play a game.  Include as many of the ions as you can.   The challenge is to create a set of cards which can be used to play solitaire.  Hand in your set of  compounds.  

Practice making at least 15 compounds, write their formula and write their name! 

Here are some patterns on the periodic table.  Colour code your periodic table according to these patterns

Modeling Atoms, Elements, Compounds

 Practice questions:   What is an atom?

An analogy for Atoms, Compounds and Formula, drawn by SN This video is the first in the series for beginner Chemistry. In this video, I use the analogy of the atom as units very much like "lego bricks". This analogy was first used by researchers in MIT.

assignment : 

practice making a model of ATOM, ELEMENT, COMPOUND, MIXTURE  and label it. practice making lego formulae.  Take a picture of the lego formulae you did in class

We will learn the analogy of LEGO and  practice building lego compounds, and writing lego formulae.

Make as many combinations of compounds as you can with the boxes of lego provided

Take a picture of the work you did in class

Examples:

The Nature of Sound

 Sound is a mechanical wave, a longitudinal wave...Today we explored the nature of sound by reading a printout of this information from this website 

Sound is a Pressure Wave 

Assignment: 

Write notes on this website and get ready for a quiz on this material. Write a one page summary. 

Also, on the same page, write OBSERVATIONS on observing  a longitudinal wave using slinkies provided in class .  write your observations. 

5 marks 

We also tested our hearing in class. How old are your ears? 

Can you hear these frequencies? 

Scientific Method Reading activity

 Read this article  called The 60 Year Old Scientific Screw Up that Helped Covid Kill 

Summarize this article in a cartoon, or a mind map with the main points of this story.  

Points 

30 points. :  Make a powerpoint, a digital mind map or a cartoon

27-30.   Brilliant work. you tell this story as a very creative  power point or cartoon which uses ink and colour and it is exceptionally done with expression and humour . you include all the points 

24-26- Excellent work.  you tell this story as an excellent power point or cartoon or mind map done in colour and it is done very well. 

15-23 - Very good work. You tell this story in a powerpoint or cartoon or mind map and you take care to do it.  

0-15 - This is a good start but it is not complete 

Analyzing Data

 Have a look at the class data table for measuring the LxW x H of the classroom

Answer the following questions: 

1. Copy the data table

2. Notice that the numbers are not identical. Identify at least 3 factors that account for these differences

3. Which column shows the most variation? L,W, or H? Why?

4. Which numbers are most likely to be true? Explain

5. How would you reduce the error?
