Color Your Brain.
When one considers a organizational
system, it is often either economic or political. What, then,
is the human brain? It is simply the "power supply" for your
senses, or is it more? An image of the human brain [more precisely,
brains, because there are several of them in our bodies] was handed
out, and we were to color it according to its various functions.
Christine Scott (Beethoven School)
Primary and Secondary Colors.
She showed several colorful books, and demonstrated mixing colors,
using food coloring [red, yellow, blue]:
| red + yellow | = | orange |
| red + blue | = | purple |
| yellow + blue | = | green |
| red + blue + yellow | = | black |
Dana Gentile (ST Barbara School)
Vibrations and Sound.
1: Rubber Band Guitar
She made a little guitar out of "lunchroom castoffs". She used
a milk carton as sounding instrument, 4 rubber bands as strings,
and a tagboard as a bridge. She taped the carton shut, wrapped
the rubber bands around it longways, taped the tagboard into a
triangular shape, and put it under the rubber bands. She strummed
to obtain a presentable sound, and then moved the bridge to obtain
a different sound. Very interesting!
2: Plastic Cup Telephone
She made a telephone out of 2 plastic cups, a fish line, and two
paper clips. She poked small holes in the cups with the paper clips,
and then tied ends of the fish line to the paper clips after sending
them through the base from outside to inside. When she pulled the
line tight, and spoke into the cup, a person at the other end could
hear her voice.
Desiree Raddetz (ST Barbara School)
Bubbles.
She added a little liquid detergent [Joy] to a
cup of water to make soapy water, and then blew bubbles with
small straws. She showed the different colors of the bubble, and
had a contest among groups to see who could blow the biggest
bubble. She introduced graphing techniques to show bubble
sizes.
Laura Shimkus (Greeley School)
Easter Eggs.
We put a hard boiled egg in water, and then added
a little vinegar. Little bubbles formed around the base of the egg.
Why? Then she used natural coloring to dye the eggs, putting them
into the colored solution for about a minute. The colorings were
beets, red cabbage, red onions, and tumeric (yellow). The eggs were
then dried on a paper plate. The other class members also dyed
some eggs.
Cynthia Southern (Spencer School)
Can you tell the source of the sound by listening?
She had a bell and a whistle, and had "contestants" blindfolded,
with little cards to signal their guess as to the sound source.
They were able to distinguish the sounds.

Puzzles [inside plastic box].
Form an equilateral triangle out of 8 blocks.

Pam Gibson and Bonnie Anderson (Libby School)
1: Math Square Game
Take a piece of paper and put 7 squares on the page. Put a number
[0-9] inside each square. Then pick a target number. How many
the target number be formed with arithmetic operations using only the
numbers in the square? This is a contest.
2: Home-made Lava Lamp
Use goggles for safety. Add tap water, green food coloring,
vegetable oil, and table salt to a container [1 liter or so]. The
oil goes to the bottom because of the salt. Then, as the salt dissolves
in the water, bubbles go to the top.
3: Zog Hotel
Classify the "animals" on cards by the following
