The TJHS AP chemistry class has been doing a lot since we visited Jean Lafitte National Historical Park. While in the park, we took different plant and water samples from three different locations. We have been doing tests on the water to check for ions in the water. We have also done test to check for the waters hardness. We compared the hardness of the water from the park to the hardness of the tap water. As for the plants, we have performed chromatography on the different samples. This separates the different components of the plants. We will look further into the chromatography of the plants to see how the different samples are similar and different.
