High School Biology-Chemistry SMILE Meeting

Notes Prepared by Porter Johnson

Estellvenia Sanders (Chicago Vocational HS) Digital Numerics
Estellvenia uses these activities with her high school students.

She gave us a sheet with the numbers 1-20 located randomly on it, and we were told to touch as many of the numbers as possible over a given time period (10-20 seconds), timed by a partner using a stopwatch.  We were to touch the numbers in increasing order (1 ... 2 ... 3 ... ) with an index finger. We recorded the total number touched  by each of us over three trials.  Then, we analyzed and compared the data.  By this exercise, some of the students will be able to remember and identify the numbers more quickly.

We then saw how sign language digits (numerically) can be combined with standard American Sign Language [http://www.lessontutor.com/ASLgenhome.html] symbols to speed up sign language, in that some letters have both "letter" and "number" signs in the 1867 version.  In the modern version of sign language, all letters have letter symbols http://www.masterstech-home.com/The_Library/ASL_Dictionary_Project/ASL_Tables/Alphabet.html, and numbers have separate number symbols, http://www.masterstech-home.com/The_Library/ASL_Dictionary_Project/ASL_Tables/Numbers.html, so that no mixing of  numbers and letters occurs.  Very interesting, Estellvenia.

Frana Allen (Skinner School, grades 1-5) The Nose
Everybody's nose may look different from the outside, but all noses have essentially the same function and internal structure.

This subject is sure to be fascinating for our students! 

Winifred Malvin (Carver School) NASA Handout:  Rockets.  A Teacher's Guide with Activities in Science, Mathematics, and Technology available from Amazon.
We started with three sheets of paper of three different colors, and a set of directions to make paper rockets.  We cut a 4 cm by 28 cm strip of paper, and rolled it diagonally around a pencil, taping it in three places.  We then removed the pencil, cut off the ends of the paper, put fins on one of the ends, folded the other end over and taped it shut, and inserted a straw.  The rocket was launched by blowing through the straw.  Alternately, you could blow up a balloon and attach it to the straw for a more vigorous launch.  Questions on the performance of the rocket, the function of the fins, the number of fins needed, and their position on the rocket are discussed the NASA Handout.  Good stuff, Winifred!
