We decided to do the age-old "stick celery in colored water to see what happens" experiment. We had some wimpy/wilted celery in the fridge, which would be the perfect specimen for this experiment.
I asked Aikman what his predictions would be, which he said he had no idea. Hmmm... we definitely need to talk more about predictions! Anyways, we set the celery in the colored water, and let them sit. He patiently waited for about 3 minutes waiting for 'something' to happen. I reminded him that sometimes we have to wait a while to see what happens. After 2 days, this is what the stalks looked like.... just touches of color.
We investigated the stalks and leaves, and talked about how the veins take the colored water to the leaves. We pulled off the veins to see how they too are colored, and that there are not veins throughout the entire celery stalk (and thus, the entire plant did not turn colors).
In Teacher Tom fashion, I let Aikman decide if he wanted to let the plants sit in the water, or if it was time to toss them. He opted to allow them to sit longer. As a result, in a week's time, more than just the tips changed color....
Only the left stalk in blue water isn't obviously blue!
Pretty cool, huh?
Oh, and a "mommy note," if you get wimpy celery, just stick it in water for a few hours, and it is back to it's old crunchy self! Wish I would have known that before I trashed the rest of the bunch!
