High school students studying biology can use the Internet to further investigate science concepts and hands-on activities. Websites can provide labs and useful information to enhance classroom lessons. High school biology food web activities include fermentation in yeast, mold science fair projects, parts of the plants you eat and lactose intolerance experiments.
Yeast
Learn about yeast and fermentation by checking out websites with lab activities. The University of Pennsylvania Biology Department's yeast lesson offers students an experiment to test whether or not growing yeast inside test tubes with warm water and sugar is an aerobic or anaerobic. Aerobic means using oxygen, while anaerobic means without oxygen. Students will test the rate of alcoholic fermentation in yeast by measuring the amount of carbon dioxide that is formed and differing amounts of sugar will be used in each test tube.
Mold
High school students looking for science fair projects can learn about a mold project from Education.com. One topic presented is whether or not bread mold can be transferred to other foods. Students place moldy breads with other food items to see if the other food becomes moldy too. This experiment would help high schoolers come up with their own projects and learn about this particular experiment. The site also breaks down how the science project should be executed, by forming a hypothesis and reaching a conclusion.
Parts of the Plants You Eat
The University of Pennsylvania Biology Department offers a lesson about the parts of the plant you eat. It teaches high schoolers about plant biology. Students will examine tulips and learn about the parts of the plant. The lab offered for students helps them better understand what parts of the flower become the fruit that you eat and students will observe vegetables in a lab. Students will determine what part of the specific plants are edible and whether or not they are considered a vegetable or a fruit.
Lactose Intolerance
Another biology food web activity is found of the Exploratorium website. To teach students about lactose intolerance, or the lack of the enzyme needed to break down milk sugar, they will experiment with glucose test strips. Students will test the glucose in regular milk and milk without lactose. Then lactase drops, which break down lactose, will be added to the milk samples. Students will record any differences in the glucose.
