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
Organs to Go...
Students explain the principles of experimental design and reinforce the steps of the scientific method. Each group of students create a "slush" type mixture to store a chicken liver.
Curated OER
"Chips" Off the Old Block?
Learners study using analogies between common items or occurrences and science concepts. They use the analogy of cookie recipes to that of the DNA "recipes" for living things to help us explain more about mutations.
Curated OER
Whose DNA Is That?
Students investigate the use of technology in order to identify different sequences of amino acids by using online web tools. They enhance problem solving skills with amino acid identification skills and strengthening comfort with using...
Curated OER
A Watershed Monitoring Module
Students explore the relevance of water quality monitoring in relation to a local wetland ecosystem. They conduct standard water quality tests using wet tests and CBL calculators and probes. Student record and interpret the results.
Curated OER
Using Yeast as an Ultraviolet Light Measurement Tool
High schoolers accurately measure the relationship between radiation dose and either survival or some genetic event such as mutation or recombination. They investigate the damage that was done to the DNA molecule as a result of exposure...
Curated OER
Active Ingredient Screening Test for Plants
Students determine if various plant materials contain active ingredients which will inhibit the growth of bacteria. They identify plant materials and their degree of sensitivity.
Curated OER
Superbugs and Antibiotic Resistance
Students complete experiments on antibiotics and antimicrobials. In groups, they explain how antibiotics affect the evolution of microorganisms. They test various types of bacteria to discover how much resistance they have to antibiotics.
Curated OER
The Birds and the Bees, and the Flowers and the Trees
High schoolers examine the roles in which animals play in the pollination of plants. They recognize that flowers have male and female sexes. Students describe cross pollination and propose reasons for cross pollination through narration...
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
Fish and Oxygen
Students explore what factors affect population dynamics, identify factors affecting fish populations, and use Stella to model how dissolved oxygen affects fish populations.
Curated OER
Dishing the Dirt Part 2
High schoolers explore the differences between specific soil characteristics. They participate in an experiment in which they discover soil texture. They write their observations in a journal.
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
Mendellian Genetics
Students describe the inheritance patterns other than simple dominance. They are taught how Mendel's principles apply to all organisms. Students review the use of Punnett Squares. They are taught the principles of probability and...
Curated OER
Why Don't Whales Have Legs?
Students are given a variety of materials and are asked to design a heat loss experiment that results in a reasonable explanation of "Why don't whales have legs?" students work with the theory of natural selection.
Curated OER
Efficiency Means Getting More for Less
Middle schoolers measure water and make predictions about efficiency.
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
Into the Pond
Seventh graders use a pond to explore macroinvertebrates and other organisms. They use a dichotomous key to classify the organisms and maintain a journal recording their findings.
Curated OER
Chesapeake Bay Population Studies
Pupils determine how to use a quarter meter quadrant to find population density, relative density, frequency and how to calculate a diversity index while participating in a virtual field trip. They study how to establish a Correlation of...
Curated OER
Dishing the Dirt Part 3
High schoolers collect and examine different soil samples. They test for specific types of soil elements and the pH level. They answer questions about optimum growing conditions as well.
Curated OER
Dishing the Dirt Part 1
Students create a soil center on their school grounds. They begin to write in their science journals. They participate in an experiment that helps the community begin their own gardens.
