Most of the experiments we do have a very direct goal or purpose. Today, we did some open-ended experimentation, which I think is important and more gratifying for the preschool set.
I provided the supplies, and with my daughter’s direction, we began on a scientific journey with no definitive ending.
First, she filled a container with some vinegar.
Then my daughter dropped dots of food coloring into tiny cups of oil.
She was very excited when the food coloring became “eyeballs”.
Then she stirred it a little, creating “lots of tiny eyeballs”.
Then she dumped the cups into a large container of water. (She also added some vinegar to the water.)
We placed our container of vinegar in the center of our large container, and I ran inside to grab some baking soda. I couldn’t pass up the opportunity.
My daughter slowly poured the last of my baking soda into the vinegar.
She poured some oil into the small container of vinegar and watched them separate.
Then, she poured everything into the large container.
We were left with an oily, swamp-like mess to play in.
…and the rest is history.
