Implementation (MAAK)

A. Cabbage Juice Experiment:
a. Students will conduct an experiment using cabbage juice as a neutral for other acidic and non acidic substances.
b. Experiment will take one, thirty minute class period.
c. Students will take blended cabbage juice and add other substances to it to determine acidity
d. The substances that are available to students are lemon juice, diet soda, regular soda, milk, energy drink, baking soda, laundry detergent, vinegar, and rubbing alcohol.
e. Students will have a journal where they keep a log of what changes colors and what did not. They will also use colors to show what each substance changed the purple cabbage juice to.
f. Have students discuss at the end which liquids are acidic and which ones are not.

B and C
When our class was given instructions on Explore Your World Day we were initially very nervous about what we were going to do. Each of us thought back to when we were in school and how we never really connected to what was being taught. We knew that we wanted our station to be something that was hands on and simple.
As time went on, our group began researching ideas. We looked on a lot of websites that were designed to provide teachers with hands-on activities to do in their classrooms. We came across a science experiment that used red cabbage as a base for acids. After reading this we were very excited. We all realized that this would be a great hands on activity that could be liked to social studies. After we had finalized our idea we began expanding the idea. In the days leading up to Explore Your World Day we gathered materials and made sure that this activity would be something fun for young children to do. We also had to blend tons of red cabbage and collect other acidic and non acidic liquids.
On the day of the event, we first set up all of our materials and then began testing it out for ourselves. The science portion of our activity entailed using red cabbage juice as a base and then testing out other liquids to determine whether or not they were acidic. Additionally, our social studies part of the station was a map of the United States that showed where the U.S. gets all of its resources and where acid rain occurs. Our connection between our two subjects was the acid in the substances as it relates to acid rain and pollution in the U.S. After setting up all the necessary materials we decided we should play with the science stuff ourselves and see what happened. We had previous predictions but what we found was actually really interesting. We discovered that if you added less acidic substances into the cabbage juice it would turn a teal color as opposed to when you dropped acidic liquids in it and it turned hot pink.
As children started coming to our station we noticed that they really enjoyed using the droppers and putting all the liquids into the cabbage juice. It was also really fun for the kids to see the colors change so drastically. The only downfall that we realized was that the experiment and map were more geared towards older students and the students that actually came by were rather young. Our table had a lot of parents coming by and asking questions about acidity but the students were having a hard time comprehending what acid was and how it affected the colors. However, our table was a success with children, peers and adults.
Looking back on Explore Your World Day there is not much I would have changed. We all really enjoyed what we did because it actually got me interested as well as many other people. Each of us thought the experiment ran smoothly and the map was well organized and easy to read. However, reflecting back on the age level of our experiment, we agree that we probably should have had something there to better help the young students understand how acids worked in general, why things did the things that they did, and how acid rain came about. This would have made our booth even better.
