一、项目学习背景前几天妈妈告诉我们,网上有新闻报道说饼干的含油量可高了,用打火机一点都能像纸片一样迅速燃烧,吃多了对人体健康有害,所以叫我们不要吃饼干了。这个问题引起了我们姐妹俩的关注,饼干可是我们爱吃的零食,经常要在书包中放几片,饿的时候可以垫垫肚子。可是如果真的像妈妈说的那样,那饼干不是成了垃圾食品了吗?我们请教了科学老师,决定亲自对饼干中的油脂含量进行研究。
I. Project Learning Background The mother told us a few days ago that there was a news report on the Internet saying that the oil content of biscuits could be high. Using a lighter can quickly burn like a piece of paper and eat too much harm to human health, so we don’t want to eat it. Cookies. This problem has caught the attention of our sisters. But biscuits are the snacks we love to eat. We often have to put a few tablets in our schoolbags. When we are hungry, we can pamper our stomachs. However, if it was really like my mother said, wasn’t the biscuit a junk food? We asked a science teacher and decided to study the fat content of the cookies ourselves.
