Ah! What is life?
That's the question pondered as we started the New Year in our General Science Lab.
First up we built our own model DNA. This was a great way to put our thinking caps on and ease back into learning after Christmas break. The kids jokingly remarked that they thought this was science class, not art class!
After getting our thymine, adenine, guanine and cytosine in order we moved on.
In Experiment 9.2 we looking for the presence of starch in plants, namely a potato and a lettuce leaf. Sorry there's no pictures, but, the iodine on the potato did turn blue signaling the presence of starch. After soaking the lettuce leaf in rubbing alcohol overnight to break down the chlorophyll, we added the iodine and watched for it to turn blue. Unfortunately the leaf did not change colors. I'm not sure where we went wrong....
In our next experiment, it was time to bring out our worm friends and see how they respond to change.
MORE SCIENCE TOOLS!
When the light was on, the worms went into the soil. When we wetted the soil and shut off the light, the worms came up to the surface.
Finally we prepped our jars with a chunk of banana and a nylon stocking covering in anticipation of being visited by fruit flies.
Now, we wait!
Next time join us for Module 10: Classifying Life!
