<p class="ql-block">这次我们做的科学实验是【光的传播实验】</p><p class="ql-block">准备材料有: 手电筒，带孔的纸片3张，纸屏1个。</p><p class="ql-block">带孔的纸片排成一条直线，纸屏放在最后，打开手电筒的光。</p> <p class="ql-block">最后，纸屏上也有光，形状跟前面3张纸片上的图形一样。</p> <p class="ql-block">当我们把中间纸片错开后，最后纸屏上居然没有光了。</p> <p class="ql-block">结论是: 光是通过直线传播的。</p> <p class="ql-block">来看看我们班其他同学的实验吧！</p> <p class="ql-block">叶雪韩同学</p> <p class="ql-block"><a href="https://www.meipian.cn/4oxcl1us?first_share_to=group_singlemessage&share_depth=1&first_share_uid=102676435#" target="_blank">胡晨茜同学</a></p> <p class="ql-block"><a href="https://www.meipian.cn/4oosvzew?mina_from=1" target="_blank">杨奕宸同学</a></p> <p class="ql-block"><a href="https://www.meipian.cn/4omkaj0p?first_share_to=group_singlemessage&share_depth=1&first_share_uid=483995285#" target="_blank">姜钰鸿同学</a></p> <p class="ql-block"><a href="https://www.jianpian.cn/a/cr8gxwu?sc=groupmessage&sd=1&a_uid=4151474&s_uid=4151474" target="_blank">洪瑜悦同学</a></p> <p class="ql-block"><a href="https://www.meipian.cn/4omhah9y?first_share_to=group_singlemessage&share_depth=1&first_share_uid=187568713#" target="_blank">张向楠同学</a></p> <p class="ql-block"><a href="https://www.jianpian.cn/a/cr3j0xx?sc=groupmessage&sd=1&a_uid=4790490&s_uid=4790490" target="_blank">刘丁西诺同学</a></p> <p class="ql-block"><a href="https://www.meipian.cn/4omfe4pj?share_from=self&share_to=group_singlemessage&user_id=38330630&uuid=afcc30aa01091bfe14126802c634d8f5&share_depth=1&first_share_uid=38330630&utm_medium=meipian_android&share_user_mpuuid=51b60f82652b626f9acabe8e82d970f9&um_rtc=40ac2bdf926b8a25644e916433e2191c&from=singlemessage&first_share_to=singlemessage#" target="_blank">程子洋同学</a></p> <p class="ql-block"><a href="https://www.meipian.cn/4omf593l?mina_from=1" target="_blank">徐子涵同学</a></p> <p class="ql-block"><a href="https://www.meipian.cn/4om0vazo?first_share_to=group_singlemessage&share_depth=1&first_share_uid=193018248#" target="_blank">王陈晞同学</a></p> <p class="ql-block"><a href="https://www.jianpian.cn/a/cnmu12w?sc=groupmessage&sd=1&a_uid=3890144&s_uid=3890144" target="_blank">汪玉锦同学</a></p> <p class="ql-block"><a href="https://www.meipian.cn/4oj9l8mu?first_share_to=group_singlemessage&share_depth=1&first_share_uid=5588470#" target="_blank">周钰恒同学</a></p>
