In 7th grade cultural studies, we have begun our Seeds of Change unit. What exactly is a seed of change? It is an object that was "launched" during the Columbian Exchange and proceeded to alter the course of history. We are focusing on five such items: corn, horse, disease, potato, and sugar.
Students are working in "seed" groups and researching their topics through webquests, which are guided online investigations. Labs and lectures are also used to dig deeper into a topic. Today's lab had students determining the simple sugar and starch contents of various foods. The test tubes pictured here show the results of the simple sugar test. Benedict's solution mixed with a piece of food and then heated will change color in the presence of simple sugars such as glucose. Orange-red indicates high simple sugar content; green-blue indicates lower.
