Photovoltaic Array Use in Earth Science Classes

McCormick Place - Exhibit Hall, Poster Session Area, Table 3

Teacher describes installation of two solar arrays, and how students use the arrays to investigate alternative energy and effect of array angle on electricity production.

Takeaways: Solar arrays allow students to interact with a real world technology changing sunlight into usable electricity. Two solar arrays that tilt independently allow students to evaluate data from a controlled experiment. Solar energy is part of response our society needs to respond to the challenge of global warming and our need for energy.

Rise of the Mutant Weed: Using DNA Analysis Tools to Identify Mutations that create Superweeds.

McCormick Place - Exhibit Hall, Poster Session Area, Table 9

This workshop demystifies bioinformatics using free online tools. The activity explains the mechanisms behind herbicide resistance and genetic changes that help weeds avoid chemical control.

Takeaways: Participants will see a real-world example of artificial selection in action, while also increasing the awareness of free bioinformatics tools available for everyone to compare and analyze DNA sequences.
