Curated OER
Selecting Soil Organisms in Compost
Students conduct an experiment to demonstrate that many of the enzyme systems needed to break down society's wastes exist in nature among the decomposers in a compost pile. They culture compost bacteria on starch agar to examine the...
Curated OER
Molecular Evolution in Plants
Students examine chlorophylls. They explore the absorbing pigments in a variety of plants. Through activities, students determine spectrophotometrically. They compare plant proteins from the family Brassicace to assess the level of...
Curated OER
cDNA Sequencing By Restriction Project
Learners try to confirm the sequence of a given cDNA clone using the WWW tools and traditional restriction analysis. They grow the clone, prep the plasmid, cut the plasmid with restriction enzymes and compare their results to what was...
Curated OER
Cloning of Plasmid and Spinach DNA
Students ligate fragments of genomic DNA from spinach into a vector plasmid. They perform a restriction enzyme digestion. Student use a ligated DNA molecule to transform E. coli cells. Students analyze their procedures and outcome of...
Curated OER
A Living Watershed
Students, through this series of lessons, use local resources, speakers, print and video materials, as well as standard text materials to study the ecosystem of the local watershed.
Curated OER
The Cloning of Plasmid and Spinach DNA
Students will first extract genomic DNA from spinach and perform a restriction enzyme digestion on both the spinach DNA and the plasmid using the same restriction enzyme. They then ligate the cut plasmid DNA with the cut spinach DNA in...
Curated OER
Wolf Pack in a Bottle
Students participate in an activity of a mock electrophoresis using paper chromatography to study DNA and genetic restriction mapping.
Curated OER
SEPARATION OF A STARCH-GLUCOSE MIXTURE USING GEL FILTRATION
Students make a starch-glucose solution and pour it through gel in order to separate the starch from the glucose. They examine how starch is a larger molecule than glucose and test for the presence of these substances using other...
Curated OER
Estimating the Live Mass of Dinosaurs
Pupils calculate the volume of scale model dinosaurs using a water displacement method. They use formulas to calculate the live mass each of the species of dinosaur. Then they complete and discuss a series of questions.
Curated OER
Scientist Simulation
High schoolers imagine themselves working as research scientists completing the end-steps of a molecular research project and interpreting the data. They compare the gene sequences of normal and abnormal mice and evaluate the protein...
Curated OER
Estimating the Live Mass of Dinosaurs
Learners estimate the live mass of dinosaurs. Using dinosaur and modern animal models, students use simple displacement methods to calculate the volume of the models. They calculate the masses of each model. Learners compare the...
Curated OER
Studying Living Organisms
Students discover and discuss the differences between prokaryotes and eukaryotes. Using a microscope, they examine various prepared slides of prokaryotic and eukaryotic organisms.

Can You Catch Your Breath?
Students apply the the scientific method to an investigation.They develop and perform a scientific procedure for determining lung capacity. In addition, they write a report to display information and share their procedures with the class.
Curated OER
Permeability of Earth Materials
Students observe and classify the permeability of a variety of materials.
Curated OER
The Electrophoresis of Human Hemoglobin
Students analyze different types of hemoglobin. They use the technique of agarose gel electrophoresis to separate human hemoglobin molecules according to their electrical charge, size, and/or shape. Students relate the migration of...
