11/6/08 Potato and Sodium Experiment

Today in science, we viewed a PowerPoint presentation on the 5E Model. We learned all about the 5E's and what they are and how they help students learn. After we learned about them, we were given the task to set up the procedure for an experiment involving potatoes and salt. Our group decided that our experiment was part of the explore phase of the 5E Model. We decided our procedure should involve the students getting their supplies and then adding 1 Tbsp of salt with 1/2 cup of water to a potato. Then we would have them add 4 Tbsp of salt with 1/2 cup of water to another potato slice. Finally, the students should add 1/2 cup of plain water to another potato slice and see what happens between the three. The students are to record their observations and they should arrive to the conclusion that the potato with the most salt floats, while the lower sodium potato floats a little bit, and the potato with just water does not float at all. Overall, science class was extremely fun today.
