Others of us were busy at our desks, making the cotton swab skeletons. We received a Rainbow Cheese Questionnaire, with directions for tasting and evaluating the four cheese dips, and crackers and water to clear our palates before tasting the next dip. Then we had to indicate the one cheese dip we preferred most. A graph on the reverse side enabled us to plot the number of people who preferred each of the four dips, so we could see which was most preferred. Each of the dips were made from the same cream cheese, but each colored with a different vegetable dye.
Food companies do such tests to see what people prefer.
Complete directions for setting this up were included. Could be set up as a science fair project booth. Teams of us joined the strips together to form the shapes illustrated on one of the pages, and then tested them to see which shape most successfully would resist forces to change them. We were asked to predict which shapes would be strongest and weakest, and then to determine which in fact actually were strongest and weakest.
