Last Thursday, Yew Class visited HCC to take part in some light and shadow science in the science lab. We began by experimenting with morse code messages, writing then delivering a message to our partner on the other side of the lab, using dashes and dots delivered by torch light. Next, we investigated the effect of distance on shadow length. Quickly, we discovered that the closer the light to our screen, then the shorter the shadow. We measured and collected data to support our findings, then used this date to approximate shadow length when the light was at different distances from the screen. Some of us discovered that the height of the lamp also affected the length of the shadows. This is similar to how shadows change in different seasons: in summer, when the sun is high, shadows are short. In winter, when the sun is lower, shadows are longer.
