Activities
01) Investigating Photosynthesis with Algae Beads
Students will use a Wireless Spectrometer, algae beads, and bicarbonate indicator to investigate the photosynthetic activity of algae and the effect on freshwater pH.
02) Analysis of Aspirin Tablets
Students use a UV-Vis spectrometer to determine the mass of acetylsalicylic acid (ASA) in a single aspirin tablet and compare the results to the ASA content stated on the aspirin bottle.
03) Sunscreens: Conjugation and UV Protection
Students use a UV-Vis spectrometer to observe the absorbance of various suncreens in the UVA and UVB regions of the electromagnetic spectrum, and relate sunscreen performance with molecular orbital structure and degree of conjugation or electron delocalization.
04) Hydrogen Emission and Absorption Spectra
Students use a spectrometer, fiber optics cable, a hydrogen gas spectrum lamp, and the sun to compare emission and absorption lines, study atomic structure, associate light energy and wavelength with electron transitions, and calculate the Rydberg constant.
05) Percent Copper in Brass (Spectrometer)
Students use a spectrometer to create a Beer's law plot of known copper solution concentrations from which the unknown percent of copper in a brass sample can be determined.
