在科学兴趣小组活动中,我们学习了如何测量太阳高度。太阳高度,又叫太阳高度角,是指太阳光的照射方向和水平方向之间的夹角。小组活动的学习结束后,我们按捺不住激动的心情,决定亲自动手,制作一个简易的太阳高度测量器,测量太阳的高度。实验材料:一块30厘米×15厘米×1厘米的木板,一根5厘米长的钉子,一张A3白纸。实验步骤:1.将A3白纸平整地包住木板,并使白纸与木板的接口留在木板反面,以便于观
In science interest group activities, we learned how to measure the sun’s height. The height of the sun, also known as the sun’s altitude, refers to the angle between the direction of sunlight and the horizontal direction. After studying the group activity, we could not help but feel excited and decided to do it personally to make a simple solar altitude measuring device to measure the height of the sun. Experimental material: a 30 cm × 15 cm × 1 cm planks, a 5 cm long nail, an A3 white paper. Experimental steps: 1. The A3 white blanket flat plank, and white paper and board interface left in the opposite side of the board, in order to facilitate the concept
