BBSCI #2 part 3 mysterious moustache

This one does not require a lot of equipment. The hardest part is making a copy 
 
of a picture of the MONA LISA. If that is not available the name
could be changed to a picture of someone that you can easily find.
The markers require some testing so that you are using three different
water based markers (permanent ones should NOT be used). Try different black 
markers. Put a dot of the marker on a strip of chromatography paper( strips of  

coffee filters about 1/2" to 3/4" wide are fine). You should put each dot about 
 
an inch up from the bottom of the paper. Then
Follow kids directions to separate colors. Some have more blues, some more 
yellows, some more purples etc. Pick the three that you are going to use.
Cut three strips for each child that is going to do the experiment and label 
strips A, B ,and C with PENCIL (this will not separate when the water hits it)  

On each of Strip A put the dot of the first black 
marker, on each strip of B put the dot of the second marker and on Strip C with 
 
the third marker.
This is the most time consuming step, but I did it at the end of lunch for 140  

kids so I know it is not too bad.
The cut a rectangle in the mouth area of the Mona Lisa (or other picture) and 
back it with a strip of filter paper like the ones the kids are using. Then 
draw your BEST MOUSTACHE with One of the markers.
(LABEL all of the three markers A, B, and C.) After the kids bring in their 
homework , you can separate the colors of the moustache and
compare it to the markers of the three criminals. (you can give them names if 
you want) The Strip with the marker that matches the moustache will surely 
reveal the criminal. The only real trick is to choose three
markers in the beginning that have distinctive colors when they separate.
This can lead to discussions of police work, the work of scientists who
observe and match samples etc. 
The kids have a great time with this one and there is a bit of suspense
left until the next day when the 'Criminal' is revealed.
As always, your comments and results are welcome.
Have Fun!

You will create your own music machine. Tie other objects, like
old silverware, tin cans, nails, washers, etc. onto the string.
Test the sound by hitting the objects with a fork or spoon.
Change the position and type of objects to create a pleasing
sound or series of notes.
.
Try this:
Can you create different notes?
.
Can you play a familiar tune?
.
Can you make a very loud music machine?

Just wanted to give you feedback on Brown Bag Science. Our 5/6 teacher, Geoff
Busch, said that he assigned both the Wind and Temperature and Ice Keeper
projects. His 16 students loved them and he said that they have done their
best work in this grading period on those two projects. Thanks a bunch.  We
look forward to the next ones. Since we are new to telecommuncating this year, 
is there some way for us to get the archived projects from last year?
 
Thanks again, Lorna Kropp

.
.             THE CASE OF THE MYSTERIOUS MOUSTACHE
.
SCIENCE SKILLS:             CONCEPTS:
.
. predicting                   Chromatography is used by
. observing                       scientists to separate     . recording data
mixtures of substances
.
.
.                              The color black in some inks
.                                 and dyes is made up of
.                                 several component colors
.                                 which can be separated
.                                 using chromatography
.
.                               Some molecules of color are
.                                 more dense than other
.                                 colors
.
OBJECTIVES:
.
.   Students will be able to separate the colors in an ink
.      sample by using chromatography
.   Students will be able to make a chromatogram
.   Students will analyze and match bands of color
.   Students will be able to analyze data
.
INTRODUCTION:
.   Chromatography is a method which allows scientists to separate mixtures of
substances. If the parts of a mixture are colored, as in inks or dyes, they
show up as bands of color when separated. (Chromatography comes from the Greek
word that means "color writing".)
.
    Some inks and dyes are made up of many different molecules of color
particles. The particles are dissolved in a liquid base such as water or
alcohol. When the ink is used, the liquid base dries, leaving the color
particles behind. When the dried ink is put in water the different
color molecules separate into colored bnads. In paper chromatography, thick
filter paper is used as the medium on which the colors, when wet, separate and
dry.
.
THE MYSTERY
.
.   Students and teachers arrived at school this week to find that vandals had
struck. Someone had drawn a moustache on a valuable poster of the Mona Lisa.
The community was shocked! Who could have committed such a dastardly deed?
.
   Officer Anastasia, of the Police Department apprehended 3 suspects. Each was 

found to be hiding a pen which could have been used to vandalize the poster.
Each claims to be innocent.
.
   The only way to solve the crime is through the use of chromatography. First, 

detectives will analyze the inks from the pens carried by the suspects.
.  Next, the ink on the poster will be analyzed. When the results are compared
we should be able to determine which suspect committed the crime.

Brown Bag Science #13              Name_________________________
.
The Science of Sound--Creating a Music Machine
.
Materials in Bag: 2 meters of string
Materials from Home: forks, spoons, knives, ruler
.
Information: the air is filled with tiny molecules. When an object vibrates
(moves back and forth) it causes the molecules
to move. The molecules closest to the vibrations push against
the molecules next to themselves, and so on. The molecules travel
through the air and come in contact with our eardrums, vibrating
them so that we hear sound.  We say that the molecules move through the air in
waves, called sound waves.
.
.
1. Hold the ruler tight on top of a table so that about 3/4 of
.  the ruler hangs off of the table. Twang the free end so that . .  the ruler
vibrates up and down.
.
2. What do you observe?__________________________________________

3. What do you think is happening to the molecules around the

4. Tap a fork or a spoon against a hard surface, such as the
.  floor. (BE CAREFUL SO THAT YOU DON'T MARK UP A GOOD SURFACE)
.  What do you observe?__________________________________________

.
5. Tie the string around the fork so that the fork is in the
.  middle of the string.  Hold the ends of the string so that the
.  fork swings free.  Have a friend hit the fork with a spoon.

Our group is Nicole Smith,Dan Cooper,Pierre Mattar and we are in grade 9 at Rundle College in Calgary Alberta,Canada.
9 squared -9-9-9-9-9-9-9-9=9.   9 squared = 81 and when you subtract the remainder of the 9's your answer will be 9. This applies to any number except for the #1.
One of the 9's is squared and you subtract 8 of the 9's because you can only use nine 9's and one of them is been used already.If you square one of the #'s and subtract thje rest of the #'s it equals the # that you are <|D"i6F<DfYsfEN:w{W+2v%*>&]W"'$Zw0R=@6<@@b@yBT=6>[Ns>30U<:?MJk\l-~.

exstensive studies and argument that the best shape for a manhole is a circuler shape.This is due to the fact that a circuler shape provides more space than all other shapes of covers,due to the fact that no space would remain unused.The only other shape we found that could be used,is a semicircle with the flat end curved like an oval.
