Weedy Socks & Wheels
Students engage in a instructional activity that is concerned with the concept of using socks in order to collect weed seeds. They conduct research in order to illustrate the ease of how weeds are spread from one area to another....
Curated OER
Superbugs
Students research deep sea communities and discover strategies for combating antimicrobial resistance and write reports on it. They consider overprescription and prophylactic uses of antibiotics as causes for their ineffectiveness.
Curated OER
Drosophila Melanogaster
Students collect their own flies and construct crosses, then compare them to the data from lesson two.
Curated OER
Spring Fever
Students grow plants from seeds that can later be placed in outdoor settings. They care for the seeds while they germinate and begin to leaf out.
Curated OER
How Can We Observe Genetic Variation Within a Species?
Students observe intra-species variation by completing standard microbial streaking procedures. They collect data from which they draw observations and complete a worksheet.
Curated OER
How Clean Is Our Water?
Students examine samples of water to determine its cleanliness. They visit a waste treatment plant and/or reservoir. Students explore what protects the water supply from contamination by chemical or organize pollution. They trace the...
Curated OER
Life in Streams and Ponds
Students collect microorganisms, demonstrate correct laboratory/Gram stain procedure, and design and construct tables to organize data.
Curated OER
Termite Trails
Pupils observe the behavior of termites and draw conclusions about their behavior. They record data as to termite behavior and recognize elements in the experimental design which must include a hypothesis.
Curated OER
What's That Brown Fuzzy Stuff On My Plum?
Students examine Koch's Postulates by actually using them. They perform each of the required four steps to show that the brown fuzzy fungus they see growing on stone fruit (plums, peaches, nectarines, cherries) is what causes them to rot.
Curated OER
Dirty Worms
Students examine the functions of earthworms and their effect on soil. They conduct an earthworm dissection lab, and complete a checklist.
Curated OER
Transformation With A Firefly Gene
Students understand the process of bacterial transformation through experimentation. They describe the function of two important genes of the pBestLuc plasmid. They explain how to induce competence in E. coli cells.
Curated OER
Antibiotic Resistance in E. coli
Students discuss the antibiotic resistance of bacteria. They design an experiment to test the resistance of different strands of E. coli. They answer discussion questions to end the lesson plan.
Curated OER
Transformation of E. coli with Antibiotic Resistance
High schoolers participate in an experiment in which they transform an E. coli cell. They discover how the genetic make-up of the cell can be changed by added foreign DNA. They answer questions to complete the lab.
Curated OER
Windows on Life
Students explore and observe living development using live fertilized chicken eggs. They open the eggs approximately 72 hrs after fertilization and make observations for several days.
Curated OER
Integrated Pest Management
Young scholars compare and contrast the role of the honeybee in nature. They find information by using a variety of resources that could include the internet. Students take part in a paper and pencil formal evaluation with questions that...
Curated OER
CULTURING PLANTS FROM EMBRYONIC PLANT TISSUE
High schoolers 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...
Curated OER
Plant Biotechnology: Controlling Tissue Differentiation
Students demonstrate hormonal control of plant tissue differentiation and relate this differentiation to gene expression. They explore the effects of hormones (auxin and cytokinin) on the genes that control tissue differentiation in callus.
Curated OER
Comparative Embryology Using Japanese Medaka Fish
Students conduct an experiment to control the breeding of Japanese Medaka fish. They collect the fertilized eggs and view and record the fish's embryological development daily to compare the stages to human development.
Curated OER
Lights On - We Have A Quorum
Students explore basic bacteriological techniques. They investigate cell to cell communication and become aware of the environmental and evolutionary implications of this communication.
Curated OER
Plant Biotechnology: Controlling Tissue Differentation
Students demonstrate skills of biotechnology stringent aseptic technique and statistical analysis. They describe hormonal control of plant tissue differentiation and relate this to gene expression. Students observe the effects of...
Curated OER
Culturing Plants from Embryonic Plant Tissue
Student groups use lima beans to represent dicots and corn to represent monocots, soak the seeds, and separate the embryos from the cotyledons. They then place the seeds in Petri dishes in agar and observe for at least one week recording...
Curated OER
Life's Big Questions: Where Did Life Come From?
Young scholars explore the life forms that live in the hot springs of Yellowstone. They examine how microscopic creatures can survive in these extreme conditions. Students perform experiments to observe growth samples and demonstrate...
