KARYOTYPE ALTERNATIVES
Students comprehend that karyotyping is a process in which chromosomes are cut from an enlarged picture and arranged in decreasing order of size. The cells to be viewed are first chemically treated to increase the number of dividing...
Curated OER
Macro-DNA: Doing DNA Fingerprinting
Students explore gel electrophoresis using paper models. They model DNA sequences and shade the boxes on their Gel Electrophoresis Sheet which represent the individual fragments.
Curated OER
Time Conceptualization
Students use this activity to establish a new mode of reference to the conceptualization of time. To present hominid evolution in terms of millions of years and endosymbiosis of eukaryotes in billions of years carries little meaning to...
Curated OER
The Electrophoresis of Human Hemoglobin
Students are presented with a scenario that requires them to electrophoreses human hemoglobin samples in order to confirm a diagnosis of sickle cell anemia and/or to determine whether individuals in the scenario are carriers of the...

The Effects of Alcohol and other Teratogens: A model using Zebrafish
Young scholars investigate the interference of various drugs on an embryo through experimentation. This is an open-ended lab to allow students to see effects of various chemicals humans choose to put in their bodies and create...
Curated OER
Using Living Organisms to Explain Evolution
Students investigate evolution in its most fundamental form: the observation of living organisms. By comparing variations that exist among living animals, students formulate their own hypotheses and conclusions about the evolution of...
Curated OER
Molecular Approaches to Evolution
Students examine the molecular studies of organisms that have led to a new era in their understanding of speciation and evolutionary relationships. Students study the allelic frequency of genes controlling specific molecules and assess...
Curated OER
Sea Urchin Embryology
Students explore the process of evolution. They examine examples of how homeotic genes may work and obtain gametes. Using a microscope, students observe the fertilization of sea urchins. They video tape the process and write a...
Curated OER
DNA Extraction
Students extract and observe a visible amount of DNA from Escherichia. coli cells. They discuss the properties of DNA. Confirmation of the presence of DNA by a reaction with an indicator is confirmed within this lesson. Many hands-on...
