This week we did a yogurt lab.  In this lab we were trying to prove that the lactose is what the bacteria which eats the lactose.  If there was no lactose in the yogurt, their would be no yogurt because then the bacteria would not be able to eat up any of the lactose. The lactose comes from the milk which is the yogurt’s  main ingredient. So in this experiment all the groups had to replace the milk with a different liquid to prove that you need The lactose in the milk, so my group used apple cider to replace it.  We started out heating up the cider then we put it in a jar then put some other ingredients in it and we put it in the fridge to cool it down. The next day we took it out to see if it turned to yogurt but the results were negative; it did not turn to yogurt because  the bacteria had nothing to  eat  and curdle. This taught me even more about yogurt now.  This was a very fun experiment can’t wait till the next one.
