Aian and Marcky made Vanilla Ice Cream based on these recipe. The experiment demonstrated the ability of ice when mixed with salt to absorb the heat from the mixture (of milk, cream, milk and vanilla flavor) faster and thus turn it into ice cream! (Dated: November 7, 2008)
... to buy "topsoil" since our plants showed some sort of mineral erosion and could perhaps use a fresh load of enriched pot soil. Yet it wasn't "top priority" in my to-do list. Not until a Science lesson suggested an activity about soil profile. So I ordered a sack of soil and asked for samples of green slate, volcanic rock, and two types of pebbles to "top" it all. Now where is that empty PET bottle?
... well almost. Of course models are limited representations of the real thing, but just to demonstrate the filtering function of kidneys, I just thought the following could be useful.
I thought I could stick closely to the structure of the lesson on Scientific Method, control, variables, etc. with this activity (pdf)on fuselage, wing size and flight of the O-wing glider.
But education should be fun right? So they played and enjoyed it they did. I'd like to think they also learned a thing or two about making a hypothesis.
So Marcky was working through the topic "plant classification". I am told he was to read through dicots, monocots, and spores.
Meanwhile, I was scanning Li and Bernoff's "groundswell: winning in a world transformed by social technologies". Next, I began juggling e-mails, facebook updates, and Google searches.
Then I took a trip to the garden patch that we call our very own "fern gully", and clipped samples of, erm, ferns.
After a quick slide prep of a spore specimen, this is what Marcky discovered under the microscope:
Interesting, heh! Now for the bonus part. I just learned that dried fern fibers can be woven into bracelets and cellphone cases.
