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 ecosystems.
Meiosis
Students use physical models of chromosomes to explore meiosis and genetic variation, and use cross over rates observed in Sordaria to calculate gene distance...
Mitosis
After learning the technique for growing roots and preparing root tip squashes for microscope analysis, students observe the root tips for evidence of...
BLAST Bioinformatics
Students analyze the DNA and protein sequences of beta globin of five mammalian species to determine their evolutionary relatedness.
Plant Pigments
Students analyze spinach pigments and chloroplasts using paper chromatography, a colorimeter, and a spectrometer to understand how plants capture light...
Transpiration
Students use a pressure sensor and a weather sensor to investigate the rate of transpiration in plants under normal and humid conditions.
Photosynthesis
Students use a carbon dioxide gas sensor to test the effect of the color of light on the rate of photosynthesis.
Cellular Respiration
Students use a carbon dioxide gas sensor to investigate the rate of cellular respiration of germinating seeds.
Homeostasis
Students use multiple temperature probes simultaneously to investigate the body’s ability to maintain homeostasis when subjected to a cold stimulus....
Cell Size
Students use a conductivity sensor to measure the effect of cell size on solute diffusion rate using agarose-salt cubes.
