Peering at the sky, senior Sierra Purden completes a physics experiment. “We are throwing a ball upward to see how long it takes and then from there we are finding the height to see how high it went,” senior Bailey Coolican said. “Mr. Krehbiel is trying to teach us how to find the height of something without actually using a ruler to measure it. Through this he is also teaching us the formulas we need to know.”
