Preparing for Conducting Our Experiment
Just yesterday, Lauren and I have listed 9 ingredients to test out on saltwater to see if they make a difference on the level of salt in the water. We also went shopping for everything and the membrane filter paper has just arrived! This wednesday, we are going to conduct the experiment. The nine ingredients we have researched about and chosen to individually evaluate are: Yogurt, Pineapple, Potato/ Potato skin, Eggplant, Multiple varieties of oil, Flax seeds, Chia seeds, Tea Bags, and Cranberries. All of these are known to have higher absorption rates and the potatoes and eggplants are especially known to absorb salt specifically! The Pineapple has enzymes that degrade certain substances so we are anxious to see thats effect on the salt. Also, when chia seeds are put in water they basically absorb it so i'm excited to see if those will absorb the salt. When we start our experiment, we will have a strainer over a bowl and in the strainer we will put the membrane filters and a thick layer of the chosen ingredient, then we will pour the salt water into the strainer and let it filter through.
