Measuring the Speed of Sound with an Echo
Students will first predict the speed of sound in the air of their classroom using a simple relationship accounting for temperature. Students...
Decoding DTMF Tones
Students will use a wireless sound sensor and the fast Fourier Transform (FFT) display of the data collection software to analyze the tones produced...
Properties of Sound Waves
Students will learn the meaning of terms (frequency, period, crest, trough, amplitude, wavelength and wave speed) used to describe waves by studying...
Animal Behavior
Students use a choice chamber to test the response of fruit flies to different stimuli and determine if there is a significant change in their...
Population Genetics
Students determine their phenotype for the PTC (phenylthiocarbamide) tasting trait and use class data to derive allele frequencies for a population.
Artificial Selection
Students follow the growth and development of Wisconsin Fast Plants and determine if limiting cross-pollination to certain plants with a desired...
Enzyme Activity (Spectrometer)
Students use a spectrometer to investigate the catalyzed breakdown of hydrogen peroxide by peroxidase.
Energy Dynamics
Students use EcoChamber containers and a carbon dioxide gas sensor to estimate energy flow and carbon cycling within a variety of detritus-based...
Meiosis
Students use physical models of chromosomes to explore meiosis and genetic variation, and use cross over rates observed in Sordaria to calculate...
Mitosis
After learning the technique for growing roots and preparing root tip squashes for microscope analysis, students observe the root tips for evidence...
