Have you ever looked on a food label and seen soy products on it, even though it wasn’t made from soybeans? This unit explores the various uses of soy in foods and how soy can be used to accomplish various functions in food science by asking students to measure the nutrient content of various foods, determine the function of soy in foods, and shows how fermentation of soy can be used to make different foods. This unit features 4 lessons and 17 files. Lessons are aligned to NGSS.

Students explore international organizations working to address hunger challenges and the growing demand for protein in these three lessons. This unit features 3 lessons and 6 files. Lessons are aligned to NGSS.

In this video, learn how Leo Koch (age 9, Maine) chooses healthy foods, like those in his Healthy Lunchtime Challenge winning recipe for Vegan Superhero Soup, to fuel his competitive running and help manage his diabetes. Leo leads an active life. As a type 1 diabetic, his nutritional needs demand added scrutiny. Because the body processes nutrients in different ways, Leo analyzes foods for their protein, fat, and carbohydrate contents.

Students conduct their own research to discover and understand the methods designed by engineers and used by scientists to analyze or validate the molecular structure of DNA, proteins and enzymes, as well as basic information about gel electrophoresis and DNA identification. In this computer-based activity, students investigate particular molecular imaging technologies, such as x-ray, atomic force microscopy, transmission electron microscopy, and create short PowerPoint presentations that address key points. The presentations include their own explanations of the difference between molecular imaging and gel electrophoresis.

This pathway outlines the process of genetic engineering with a focus on gene cloning. This pathway also provides an introduction for the ABE lab series.

This pathway outlines how genetic information is added to cells in the technique called transformation. This pathway also supports ABE Lab 5.

Students learn how engineers apply their understanding of DNA to manipulate specific genes to produce desired traits, and how engineers have used this practice to address current problems facing humanity. They learn what genetic engineering means and examples of its applications, as well as moral and ethical problems related to its implementation. Students fill out a flow chart to list the methods to modify genes to create GMOs and example applications of bacteria, plant and animal GMOs.

This pathway provides an overview of biological macromolecules and their properties. The resources in this pathway can be used to introduce or review the structure and function of lipids, carbohydrates, proteins, and nucleic acids. For a deeper look at this topic, we recommend the pathway Biological Macromolecules from the OpenStax textbook Biology for AP® Courses.

Students perform an activity similar to the childhood “telephone” game in which each communication step represents a biological process related to the passage of DNA from one cell to another. This game tangibly illustrates how DNA mutations can happen over several cell generations and the effects the mutations can have on the proteins that cells need to produce. Next, students use the results from the “telephone” game (normal, substitution, deletion or insertion) to test how the mutation affects the survivability of an organism in the wild. Through simple enactments, students act as “predators” and “eat” (remove) the organism from the environment, demonstrating natural selection based on mutation.

Students learn about mutations to both DNA and chromosomes, and uncontrolled changes to the genetic code. They are introduced to small-scale mutations (substitutions, deletions and insertions) and large-scale mutations (deletion duplications, inversions, insertions, translocations and nondisjunctions). The effects of different mutations are studied as well as environmental factors that may increase the likelihood of mutations. A PowerPoint® presentation and pre/post-assessments are provided.

Find out what the human body needs to function at its best, and why.

Western blotting is a common technique to visualize proteins and determine protein expression in cells. In this pathway, CRISPR-Cas9 edited macrophages are tested for the expression of the CCR5 protein.

In this scrollable interactive, the four levels of protein folding are explored in detail by exploring the structure of hemoglobin.

In dieser Simulation sehen Teilnehmer, wie ein Protein von Interesse, ein
rot fluoreszierendes Protein, mittels hydrophober Säulenchromatographie
aus Zelllysat gereinigt werden kann.

This simulation allows users to explore how a protein of interest, red
fluorescent protein, can be purified from cell lysate using hydrophobic
column chromatography.

This scrollable interactive explores the different roles that proteins can play in the cell. Categories of proteins covered include transmembrane proteins, proteins that make up molecular machines like cilia and ribosomes, and enzymes. The four levels of protein structure are also discussed.

In this teaching video, high school teachers Anu Deshpande and Aaron Matthieu explain what a plasmid is and why it is a useful tool in biotechnology.

A detailed overview of the circulatory system, including plasma and proteins. Designed as lesson plans, this site can be helpful for students as well.
