During my last week in the Philippines I was invited to teach a science lesson at the local school. This is the school Raymond attends. I bought supplies to do the 3 color density lab since I only needed salt and food coloring. The Principal put both the sixth grade classes together for a total of about 65 students. The goal was to separate the three colors by changing the density of each layer. We did this by adding different amounts of salt. This was the first science lab for all the students ever. After giving a demonstration and trying to explain density in my broken Bisaya, the students gave it a try. As you can see by the pictures here, they did a very nice job and I was pleased that they learned the lesson.
