Math and science are used together because when you are doing science you sometimes need to use math to help you with what you are learning. For example in class we were doing this activity where we learn what length of a mirror we will have to buy so that we are able to see ourselves completely. This activity showed us how reflection of the mirror makes you bigger or smaller when you get closer or farther. We used math in this activity to graph the activity that we doing. When we graphed the activity we had to calculate a ratio to see what kind of size mirror we will have to buy if we were to buy a mirror. With our calculations we found out that if we were to buy a mirror that we could see ourselves from top to bottom the mirror will have to be half our size. That is what math can help learn when you use it in science.
