This lab introduces students to the effect temperature has on reducing and controlling the growth of bacteria. Students will use conventionally pasteurized and ultra-high-temperature (UHT) milk to observe how different temperatures (hot, room temperature, cool, and freezing) affect the growth of spoilage bacteria. They will also learn about the importance of pasteurization in keeping food safe.
This lesson allows students to apply the concept of Mendelian genetics and learn about the double muscling trait found in cattle. Students will apply their knowledge of genetics and Punnett squares to calculate the probability of genotypes and use a pedigree chart.
Students learn about DNA by extracting it from strawberries. Students also analyze the similarities and differences of their extraction process to those on Genetic Engineering: The Journey of a Gene. Students learn how genetic testing (including DNA extraction) is useful in breeding new varieties of strawberries.
This lesson introduces students to the relationships between chromosomes, genes, and DNA molecules. Using the example of a strawberry, it also provides activities that clearly show how changes in the DNA of an organism, either naturally or artificially, can cause changes.
Students will simulate the process of gene splicing, understand the application of transgenic organisms in agriculture, and see how goats can be used for the production of goods other than meat and milk through the use of biotechnology.
Students will view the 2014 film Farmland, a documentary spotlighting six farmers and ranchers in the United States. The film portrays the business and lifestyle of a variety of farmers and ranchers. Perspectives on topics such as bioengineered (GMO) crops, animal welfare, organic and conventional farming practices, farm size, farming stereotypes, and more are presented.
Students will be introduced to technologies currently used on farms by engaging in an AppQuest to discover how farmers use mobile apps to manage farm production systems, marketing options, and make timely decisions.
Students explore the impact of fertilizer on algae growth, soil erosion, and agricultural soil and water conservation practices.
Students discover technologies that are used on farms to increase efficiency and yields and decrease costs and environmental impact.
Students will explore the carbon cycle and evaluate associated phenomena of climate as they discover the impact climate change could have on the farms that produce our food.
Students will explore the causes of hunger, both domestically and globally; evaluate potential solutions for solving world hunger; and forecast the impact of a growing world population on current food supplies.
This hands-on lesson teaches students how precision agriculture uses geographic information systems (GIS) to help farmers and manufacturers make smart, efficient, and responsible decisions about how and when they plant, grow, irrigate, harvest, and transport crops.
