At Square Roots Preschool, we feel that science is an important part of our curriculum. Preschool-aged children have a natural curiosity about the world around them, and what better way to support that curiosity than by doing hands-on experiments that ask the children to make predictions, observations, and draw conclusions.
When we studied the letter “Ee,” we conducted our naked egg science experiment. The first part of our experiment required us to place an egg carefully in a glass and pour vinegar over the top. Some students predicted that the egg would float, and others predicted that the egg would sink. The students each got a chance to pour (with a little bit of help). They observed that the egg floated! The next part of our experiment required patience. We had to wait a few days to see what effect the vinegar would have on the egg.
After a few days, the shell of the egg became soft, and the yolk of the egg became rubbery, like a ball. Since young students learn best by doing, the students got to feel the egg and yolk and describe it. It was ooey-gooey scientific fun!
Later in the week, we conducted an Egg Drop experiment, which taught us about cause and effect and prediction. Each student chose a material to protect his or her egg, and then everyone predicted what would happen to each egg. With no protection, the students predicted that
The yolk will go all over the ground!
I don’t know.
Drop it down!
I think it will break.
We then protected the egg with a paper napkin, bubble wrap, absorbent pad, plastic baggie, and a towel, in turn. Each student had the opportunity to drop their own egg and make observations about the results. We concluded that bubble wrap was the most protective material because the egg didn’t break at all!
Too often, science is considered something “extra” for young students. Science lessons help develop so many skills, so we feel it is important to make the subject an integral part of our school day.
