Experimenting with Nature


After art class we get ready to hunt for science, this week we are looking for worms in their natural habitat.
Sara is aided in her quest to prepare a happy home for our guests.

We work in teams to find the best places to look for our treasures. Night worms... Where do you think they'll be? A bright place or a dark place? Emma is the first one to find a worm. She also proves to a couple of gentlemen that girls can, and will, pick up crawlers. As if we didn't prove that with the gastropods!

Well... some of us would rather wear protection!

Students create experiments following the scientific method. Hypothesis: Slugs will win a race because they don't have a shell to carry. Theory: After racing more than thirty gastropods, we think small skinny slugs are faster than big slugs because they have less weight to move, and much faster than snails for the same reason. They also might be a little younger: as Johnmorgan stated, "kindergartener's can ran faster than Mrs. Kurkinen", thankfully they didn't comment of my weight!



The students also constructed tracks to see which gastropod could maneuver through various obstacles.  Some of us were very frustrated on the snails refusal to stay on the track. 

And so, what did we learn? Harper pretty much sums it up: 
"This is a small snail. [And it] is slow!"
