Exploring Bacterial Diversity Through Hand-Printing & Bacterial Art, Sudeshna Roy, Mark Abrahamson, Madhav Nepal, Nicholas Butzin Sep 2022

Exploring Bacterial Diversity Through Hand-Printing & Bacterial Art, Sudeshna Roy, Mark Abrahamson, Madhav Nepal, Nicholas Butzin

iLEARN Teaching Resources

Bacteria are present in a wide variety of environments, ranging from deep ocean floor to volcanoes. Based on their niche, bacteria can differ in their physiologies. This lesson is designed to make the students aware of the presence of bacteria in their surroundings. This lesson also aims to demonstrate the diversity in bacterial species using colorful bacteria. The bacteria used in this lesson require specific temperatures to grow and develop their color. By the end of this lesson, students will be able to visualize the different colored bacteria on the plate.


Toward Genetic Engineering: Teaching Transformation Using The Pglo Plasmid In High School Classrooms, Isaac Kovash, Tahmina Hossain, Sudeshna Roy, Michael Mitchell, Madhav P. Nepal, Nicholas Butzin Sep 2022

Toward Genetic Engineering: Teaching Transformation Using The Pglo Plasmid In High School Classrooms, Isaac Kovash, Tahmina Hossain, Sudeshna Roy, Michael Mitchell, Madhav P. Nepal, Nicholas Butzin

iLEARN Teaching Resources

In this lesson plan, students will learn about genetic engineering and perform the same transformation protocol used by scientists on a daily basis around the world. Genetic engineering is a technique used for direct manipulation, alteration, or modification of genes or genomes of an organism to manipulate the phenotypes. The use of genetically modified organisms (GMOs) has emerged everywhere as a mainstay from agriculture to pharmaceuticals. Through this lesson, students will transform Escherichia coli with pGLO plasmid, which give a brilliant fluorescent green glow under UV light. Students will also learn the central dogma of molecular biology: DNA à RNA …


Teaching Dna Extractions From Fruits (Strawberry, Banana, Kiwi, And Watermelon), Amadea Pourier, Dillon Nelson, Wiyaka Pomarleau, Kay Cutler, Madhav P. Nepal Apr 2022

Teaching Dna Extractions From Fruits (Strawberry, Banana, Kiwi, And Watermelon), Amadea Pourier, Dillon Nelson, Wiyaka Pomarleau, Kay Cutler, Madhav P. Nepal

iLEARN Teaching Resources

In this lesson, students will use a simple DNA extraction solution and isopropyl alcohol to extract DNA from strawberries, banana, kiwi, and watermelon. The extraction solution consists of dish detergent, water, and table salt. Grinding or crushing the soft fruit tissue will separate the cells. The dish detergent breaks down the membranes, exposing the DNA to the solution. The salt helps the DNA molecule to stick together from the proteins. The cold alcohol dissolves everything but the DNA, which forms an insoluble layer of the DNA allowing it to be visible.


Teaching Medicinal Plants Used By Native Americans, Amadea Pourier, Dillon Nelson, Wiyaka Pomarleau, Kay Cutler, Madhav P. Nepal Apr 2022

Teaching Medicinal Plants Used By Native Americans, Amadea Pourier, Dillon Nelson, Wiyaka Pomarleau, Kay Cutler, Madhav P. Nepal

iLEARN Teaching Resources

In this lesson, students will also be able to identify four medicinal plants, describe their characteristics and discuss medicinal uses. Students will use their senses to experience the uses of these medicinal plants. The plants highlighted in this lesson are Chokecherry Tree, Prairie Sage, Lead Plant, and Purple Cornflower. The senses used may consist of smelling the aroma of sage, burning the root of the purple coneflower, or tasting the infusion of the Lead Plant.

Curriculum Development Of Agricultural Educators In South Dakota, Mercedes Lemke Jan 2022

Curriculum Development Of Agricultural Educators In South Dakota, Mercedes Lemke

Electronic Theses and Dissertations

Curriculum development is an essential component of teaching. Understanding how agriculture education teachers utilize, develop, and adapt content to curriculum can benefit teachers to spend less time on curriculum development. Recognizing the way agriculture education teachers use content in curriculum implementation will allow curriculum developers to create materials that can effectively be used by teachers. This study also looked at the affects of how COVID19 pandemic affected the way teachers locate and develop curriculum. The purpose of this study was to evaluate the way agriculture education instructor’s usage of content for curriculum development, implementation decisions and the affects of the …
