Column: Experiments confirm creation's miracle
By PAM SLAGTER, Worthington Christian School
WORTHINGTON — Science is the knowledge or study of the natural world based on facts learned through experiments and observations. The students at Worthington Christian School have been conducting several experiments and observations in their science classes.
Recently the fifth- and sixth-graders concluded a study about the ear, sound, eye and light. They learned that they could make a unique instrument by strategically cutting a drinking straw. The sound that the straw made was similar to a kazoo. There was a lot of “music” that could be heard in the hallway on the day that this demonstration was conducted.
Another activity that proved to be fun for the students was experimenting with a tuning fork. The fork was struck then immediately placed in a glass of water. The vibrations of the fork caused water to splash everywhere. There was probably a contest as to who get the most water to splash out of the cup since there were water puddles on the floor and counter. Kids and water is recipe for fun!
The students were also able to experiment with prisms to make color spectrums. They enjoyed the beautiful arrays of colors that they were able to make from the sunlight.
The conclusion and highlight of the science unit was the dissection of a cow’s eye. The students became mini surgeons by donning rubber gloves, goggles, and using scalpels. The first and most difficult task with this operation was cutting away the fat and muscle from the eyeball. Once this was completed they then proceeded to find these various parts of the eyeball: sclera, cornea, pupil, iris, lens, aqueous humor, vitreous humor, retina, optic nerve and blind spot. The diagram worksheet that the students had completed prior to the dissection became more understandable to them once they were able to see the various parts of an eye.
Some of the students were very hesitant to participate in the dissection. Once they began the procedure, however, they were awe-struck that the seemingly gross contents of the eyeball all work together to give the cow vision. Some students commented in their written report that they could see the handiwork of God in the eye of a cow.
Psalm 139:14 says “I praise you because I am fearfully and wonderfully made.” After these experiments and observations, we have come to the conclusion that we can praise God because all of creation is fearfully and wonderfully made.
