Estellvenia then put a rusty paper clip into a small beaker, covering it with a layer of drain cleaner [The Works™]. Will the paper clip eventually be cleaned this way?? We will check it at the next class meeting.
Good stuff, Estellvenia.
Chris Etapa [Gunsaulas Academy] Nature Walk, Part I
Chris took us outdoors on a stroll through the campus to collect several specimens of various types of leaves. We obtained simple leaves, compound leaves, single leaves, and leaf bunches still on their branches. We will take these home, put them between layers of newspaper under weight, and press them. At the next class we will bring back the pressed leaves, to continue with Part II of this experiment.
What happens next time?? Very nice, Chris!
Robert Albert [Roosevelt HS, science] Observation
Robert took out a shopping bag filled with cubes made from empty milk cartons -- the cubes had one missing side where the carton tops had been cut off. Our cubes were similar, with the numbers 4 and 3 on the front and back sides, 1 and 6 on the left and right sides, and 5 on the bottom. All cubes were identical. Each person saw only the numbers on one cube. We then were asked to seek a pattern, to predict what number should have been placed upon the missing face. We first saw only the numbers on the sides; since the cubes were identical, each person had the same information in order to extrapolate. These numbers represent observations, and it might be difficult to suggest a pattern. The possible pattern became more evident when we looked at the base, with 5 on it. It was suggested that the sum of front-back, left-right, and up-down numbers might be 7, since 4 + 3 = 7, 1+ 6 = 7 and 2 + 5 = 7. The missing number  could then be predicted from this inference. Of course, that prediction cannot be confirmed until and unless we see the number on the missing side. So it goes with scientific analysis.
Next we replaced the numbers by names:
|Nat||A name, opposite Mat|
|Pat||Letter spacing: b-c ... f-g-h ... m-n-o-p|
|Rat||An animal: bat cat rat|
|Sat||A fat (cat or bat) sat on a (hat or mat).|
Next set of cubes:
Robert uses this
exercise in class to highlight the difference in observations and inferences.
You really made us think!
