Transpiration
In this lab, students investigate the rate of transpiration in plants under normal and humid conditions. Then, they will have the opportunity to design...
Mitosis
After learning the technique for growing roots and preparing root tip squashes for microscope analysis, students observe the root tips for evidence of...
Meiosis
Students use physical models of chromosomes to explore the topics of meiosis and genetic variation. First, students use “paper chromosomes” to model...
Energy Dynamics
Students set up a variety of simple detritus-based model systems to estimate energy flow and carbon cycling within an ecosystem. Students set up their...
Artificial Selection
Students follow the growth and development of Wisconsin Fast Plants® (a variety of Brassica rapa) through two generations. These plants have a short life...
BLAST Bioinformatics
In this activity, students employ the same tools used by research scientists all over the world: online databases that allow comparison of DNA and protein...
Population Genetics
Students use class data for the PTC (phenylthiocarbamide) tasting trait to derive allele frequencies for a population. Based on their phenotype and predicted...
Mathematical Modeling of Evolution
Students work with a mathematical model and computer simulation to explore how inheritance patterns and gene frequencies change in a population. The model...
Animal Behavior
Students test the response of fruit flies to different stimuli and determine if there is a significant change in their behavior. They do this by constructing...
Experimental Variables
Students practice identifying variables in a color fading experiment.
