Some possibilities include adding sugar or salt to the gelatin, or comparing results of different clear substances listed on the table. Many science buddies projects include detailed step-by-step protocols to follow, but this one is completely open ended and you will have to design your own experiment. You will be measuring the refraction of the angle of the light as it passes from air into the gelatin using a protractor. Once you have understood how to apply Snell's law, then you should be able to set up the experiment. The best place the start on this project is with all of the background reading, including the example problems give in one of the sites. When you pass the laser light through the gelatin or other medium, the light is bent at an angle according to Snell's law. Grace 7177 has asked some good questions that should help you get started. This is a great, but challenging project. ![]()
