Teaching Biotechnology With Models
Pupils are introduced to biotechnology by using models. The teacher uses A Sourcebook of Biotechnology Activities, Rasmussen and Matheson project co directors. One of the activities in the book is: students use a scale models to very...
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
Lost Baby
Students simulate the steps involved in creating a DNA fingerprint by the RFLP technique. They analyze RFLP patterns to determine the parentage of a missing baby.
Curated OER
cDNA Sequencing By Restriction Project
High schoolers 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...
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
Student Investigation on the Immune System and Hemeagglutination
Students study laboratory protocol for hemagglutination experiments.
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?
Students 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
Learners 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
Students 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
Pupils 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
Chesapeake Bay Population Studies
Young scholars 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...
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
CULTURING PLANTS FROM EMBRYONIC PLANT TISSUE
Pupils use this laboratory exercise as a growth medium that contains the macronutrient and micronutrient needs of plants. They observe the effects of different hormones on tissue cultures and must use variations of the basic growth medium.
