Virginia O'Brien (Higgins School)
did "For the Birds" - (handout) with us. We each received a small brown bag containing a pine cone, peanut butter, 2 feet of heavy orange yarn, plastic knife, napkin, piece of newspaper. We tied the orange yarn to the large end of the pine cone, used the knife to cover the bottom 2/3 of the pine cone with peanut butter (with the newspaper to keep things clean), then dipped the peanut butter end into a large bowl of birdseed. Simply suspend it from a nearby bush or tree and watch the birds! Included were forms for keeping a Bird Watch Diary, and how to do feather painting, make brown bag nests, and "binoculars" from cardboard tubes. A good combination of hand-skill learning with observation and data taking. Thanks, Virginia!
Lilla Green (Hartigan School)
put us to work on the Skeletal System, Strength of Bones, and two pages of skeleton cut-outs to color, cut, and assemble to display a human skeleton. She explained how her children would cut a skeleton transparency into puzzle pieces and make a challenge to the class to put the skeleton together correctly, learning the names of bones in the process. Materials she placed out on the table were: stick glue, scissors, paper fasteners (for bone joints), 12 inch x 17 inch construction paper (yellow, green, orange), crayons, hole punch. In class, students would examine real bones, some soaked in vinegar (and which would bend!) (handout - Strength of Bones).
Books on display were the following:
Erma Lee (Williams School) passed out packs of 74 soda straws to five groups, and challenged us to build the tallest tower. The trick is to find ways to join the straws in a stable way. The winner was about 1 meter high! Great fun, and a way to build cooperative skills and creativity.
NOTE: To remove stickers, tape, labels, gum, etc get this substance:
Carl Martikean (Wallace HS, Gary) asked us, "How many times can you fold a piece of paper into halves?" Well - after making some guesses we got busy doing the experiment to find the practical answer: 7 or maybe 8 times! Why? Because the paper gets too thick to bend. It works with onion skin paper the same way! There are many things that can be learned from this other than the obvious. What are they?
Sally Hill (Clemente HS)
passed out Math Bingo sheets to us, to play the game as couples. The page was divided into a 5x5 grid of rectangles, each containing a specific math expression for a sum, difference, product, fraction, area, percent, etc. Having supplied us with markers, she called out various possible answers to the math questions, like "16" or "3.1416 ... ". If this was one of the correct answers, we would then mark the spot with a green disk. As soon as one of us got a diagonal filled, we called out BINGO! Then we had to go to the board and do the math operations called for in the rectangles on the diagonal. What a great idea!
Lee Slick (Morgan Park HS)
showed us a piece of magnetic strip. Cut it in two, then move one piece over the other. What happens? It jumps! Why? A good way to get students involved with an investigation of magnetism, with non-traditional magnets. If the the top strip is turned over, there is no interaction. Why? Lee also mentioned that it was not a good idea to put these strips too close to computers, computer screens, or diskettes, because they will either destroy data or interfere with the operations. Thanks, Lee.
Kimberly Baker (Fairfield Academy - formerly Marquette East)
handed out a page titled Don't Use It All Up! (Earth Science), and put us to work listing 15 uses for water. The winner gets a fresh bottle of water! Can you do it? We compared answers, which made it interesting. Next, groups of 2 or 3 received a plastic container (about 12 inches x 6 inches x 14 inches) with sponges inside. The container represents the earth. With sponges removed, add water to a depth of about 2 inches and mark the level. This represents the height of the water table. Think of a use for water, then add a sponge to represent that use. With each sponge (use) added, the water level would drop as the sponge soaked it up. Finally, the level dropped nearly to the bottom. The moral: Water has many uses, but there is only a finite supply. Therefore, re-use is essential. Conserve water, use the same water for two purposes when possible, re-use water. When we squeezed out the sponges, the water did not return to its original level because sponges retained some; re-use is not 100% efficient. A beautiful lesson!
Pearline Scott (Franklin School)
started us off with a page from a calendar. We had to pick out any 3x3 array of numbers on the calendar, eg:
Next, we formed into two teams, and Pearline placed standard (Cartesian) x,y coordinates on the board, with the usual 4 quadrants and the origin at (0,0). Teams alternated in sending a representative to the board to locate a point. The objective was to get 4 points in a row [up, down, or diagonal], and to keep your opponents from doing so in the process. It took about 10 - 15 rounds before one team won. A fun exercise in plotting and graphing!
Finally, starting with a set of squares on a paper, draw straight lines within a square to form 2 triangles and 2 quadrilaterals inside. What can you do with one line? ... two lines?...three lines? A good geometry exercise, and one that requires some thought and creativity! Thanks, Pearline!
WHAT WILL WE LEARN NEXT TIME?!
