Sept 23 Class

Today we did a lab that tested acidity. We had baking soda and vinegar and we mixed the two together which created a reaction. This showed us that this is what happens with acid. So, we used baking soda and tested the acidity of different fruits. We tested, white grapefruit, pink grapefruit, orange and lemon all in the juice form. After we tested these we then tested each of this in a chunk form. We placed the chunk into a cup and then poured baking soda over top of them. The reaction wasn't as large on the chunk as it was in the liquid form. I think this is because with the chunk, there was more surface area for the reaction to occur, so it was more spread out than in the liquid form. The liquid was also more concentrated than the chunk. I feel that this would be a great activity to do with younger students in a classroom, because it deals with food that they may encounter everyday in their lives. When something is closely related to them, they are more likely to be able to draw the connection and the activity will have more meaning to the student.
