Margia Artis (Herzl School)
(handouts - The Model Plant, Can You Fool a Plant?) had placed a set of vocabulary words on the board, related to plants: eg. chlorophyll, petal, pollen, taproot, sap, stamen, seed, pistil, cotyledon, etc. We each received a page called a Bingo Grid, which divided the page into 25 squares, 5 squares on a side. And a handful of sunflower seeds. She asked us to write the vocabulary words, at random, onto each square of our Bing Grid. Then she read a definition, and we were to place a seed on the square with the word that fitted the definition. And so it went, until someone hollered BINGO! But then that person had to read the word and state its definition before she was accepted as a legitimate winner. How to make a game out of learning plant parts! We also were invited to the table to fabricate a colorful model of a plant from various materials. Great!
Alma White (Woodson North School)
(handout - Oatmeal Play Clay) invited us to the table where she had flour, oatmeal, water, and some bowls, along with vegetable dyes. Soon we were busy making oatmeal play dough. Many of us tried to form it into the shape of a swan, since Alma had placed a Japanese haiku on the board and challenged us to add to it or subtract from it:
All swans in a pool (5 syllables) As they go by they look like (7) Bright sunny rainbows (5)
Marjorie Fields (Young Elementary)
(handout- Clock Shop) We each received a page with a clock and minute and hour hands to cut out. Also, a paper plate and a fastener. We colored the clock with crayons, the hands and plate too. Then the face of the clock and hands we mounted with the fastener (at the center) of the plate, and we could then indicate the time to the hour and minute. Her very young students would become involved in hands-on learning about how to tell time, and Marjorie provided us information to make games out of it. Wonderful! We should have had more TIME to do these ideas justice.
Allan Evans (Sherwood School/special ed)
handed each of us a packet of M&Ms. He explained that he subbed, and would often come into a class where he would have to improvise and think on his feet. So - he figured teachers would like the M&Ms - but no eating till we're done! And then he asked for ideas on how to use them to get students to learn. "What can we do with them?" he asked. Before we ran completely out of time, he had received more than a dozen suggestions from us, among them: statistics of the distribution of the M&M colors; median, mode, average. Use them as a set of standard weights to weigh objects. Many ideas in a short time!
John Scavo (Richards Career Academy) handed out copies of Albert Einstein, The Non-Nerd's Scientist of the Century. http://www.time.com/time/time100/poc/magazine/albert_einstein5a.html. He pointed out some of the highlights to us: Interesting Biographical Facts/Timeline: eg. 1895 - failed an exam that could have let him study to be an electrical engineer. etc. And Time Dilation - some equations and discussion. Thanks, John!
Carl Martikean (Wallace HS, Gary)
reviewed some Weird Science with us, that appeared in one movie: A stray planet comes by and eclipses 3 suns at once! How come? And giant bats come out at night! Carl mentioned some movies he thought had good science: Outbreak (about the Ebola Virus) and Dante's Peak (about volcanoes). Thanks, Carl!
Earnest Garrison (Jones Commercial HS) (handout - Evolution: Rap It Up! ) http://www.accessexcellence.org/AE/AEPC/WWC/1995/evolution.html. It involves relating to students and their interests by using a CD of the rap group Salt-N-Pepa that includes their hit, None of Your Business. A set of words is provided dealing with evolution, and they are read in rap rhythm to that tune. Fun and interesting!
Porter Johnson (IIT)
presented exercises on codebreaking and construction of a regular icosahedron. The recent book on codebreaking, Between Silk and Cyanide: A Codemaker's War 1941-1945 by Leon Marks [ISBN 0-684-86422-3] describes the making of codes and communications with allied agents in Nazi-held territories. Their coordinated activities were said by General Eisenhower to have shortened the war by 3 months. Marks was inspired by the short story The Gold Bug by Edgar Allen Poe.
Now, here is your very own coded message.
|A 15||B 01||C 08||D 13||E 00||F 10|
|G 16||H 07||I 07||J 33||K 12||L 20|
|M 15||N 11||O 01||P 22||Q 40||R 10|
|S 02||T 01||U 13||V 27||W 34||X 60|
|Y 39||Z 49||-----||-----||-----||-----|
The key to deciphering the message is the apparently meaningless phrase ETAOIN SHRDLU, which represent the twelve most common letters in English, arranged in decreasing order of occurrence. Thus, the most frequently occurring letter in a message is likely to be E, and so forth. You don't learn anything about cryptography unless you try to decode the message, but the answers are given below.
It is a good "multi-cultural exercise" to remember who said each of these things.
|x to +||e to x||z to e||t to z|
|q to t||a to q||y to a||o to y|
|j to o||i to j||w to i||n to w|
|g to n||s to g||p to s||h to p|
|v to h||r to v||f to r||d to f|
|k to d||l to k||u to l||c to u|
|m to c||b to m||+ to b||------|
ICOSAHEDRON. An icosahedron [greek] is a solid with 20 planar faces. The regular icosahedron is one of the five Platonic Solids:
