How do we attract students to the field of science? What is it that is going to draw them into the field and keep them there? I believe that the answer to this question can be found by talking to scientists themselves.
Going beyond what most students in 9-12 already know about the factors required to help seeds sprout and grow (water, warmth, substrate), the investigation in "A Salt on Germination" focuses on the practice of calculating how much of a concentrated stock must be used to create a diluted
The goal of my ETP is for my students to work collaboratively to design an arrangement of solar cells that produces the most current.
Engage students with a demo or video that shows "surprising" polar/ nonpolar differences–use Scotchgard on cloth or paper towel to create a pattern then dip into a colored solution.
At Genentech, I worked on different assays to build my own laboratory and analysis skills. I developed ways to improve the ELISA assay with my mentor. I used proper laboratory protocol to document when I perform an experiment.
This exploratory/investigative experiment is designed to provide a set of laboratory skills to meet the 21st century technology standard to the students. This experiment asks the students to investigate the oxidation -reduction chemistry behind the breathalyzer.
