Frequently Asked Questions
A: We decided to choose strawberries as our natural indicator because after some research, we discovered that strawberries are already slightly acidic.
Q: Did you have any predictions?
A: We predicted that adding a strong acid would turn the indicator a darker pink or red. We also predicted that if we added a strong base it would turn the indicator a bluish or purple color.
Q: If you did not choose to use strawberries what would you have chosen as your natural indicator?
A: If we didn't use strawberries, we would have used blueberries. We think that using blueberries would have given more clear results because they have a low pH but can easily become a darker red when acid is added.
Q: What would you have done differently in this lab?
A: We would have filtered the strawberries more before we started the lab. Our grocery shopper blended the strawberries thoroughly and filtered them only once before bringing them to school. Our whole group agrees that it would have been beneficial if we had filtered more than once before starting the lab. This would have saved us some class time.
