Here is your free activity for November! A science experiment about cranberries!
Science Experiment Background: Cranberries may be the official fruit of Thanksgiving. Whether it is cranberry sauce on a turkey or a delicious cranberry pie, the berry has become a staple on most tables during the holiday. Beyond being a popular treat, cranberries contain anthocyanins. Anthocyanins are pigments that change color depending on if they are reacting with an acid or a base. Because cranberries are naturally acidic (it is part of the reason they have a somewhat tart taste) the anthocyanin reacts with the acid to make the berries red. However, if you change the acidity, you can change the color too.
For this science experiment, you will need a clear glass, baking soda, cranberry juice, and lemon juice. Then just follow the steps below:
- Pour one cup of cranberry juice into the glass.
- Add a tablespoon of baking soda and observe the reaction. Things to look out for are bubbling, noises, and changes in how the liquid looks.
- Wait 2 minutes, and observe if any changes occur.
- Add two tablespoons of lemon juice, and again, pay attention to see if there is any reaction.
