In this activity students build protein bracelets using beads with different colors and shapes that represent the different amino acids.
In this lesson, students will understand where and how bacteria grow. They will then design a controlled experiment to further investigate.
In this lesson, students will demonstrate the synthesis of a DNA plasmid by using a paper model, explain the significance of the new plasmid in terms of its expression of the new traits, and explain the importance of restriction enzymes, polymerases and ligases in the formation of a recombinant DNA.
Students will learn about the function of the immune system and the relationship between the immune system and diseases or disorders.
In this lesson, students investigate factors that affect the integrity of cell membranes. Beet tissues will be used as the model to investigate the types of environmental stresses that affect membrane integrity.
In this lesson, students will explain that amino acids are the building blocks of proteins. They will understand that there are 20 different amino acids, discuss the properties of polar (hydrophilic, negatively charged/acidic or positively charged/basic) and non-polar (hydrophobic, uncharged) side chains (R-groups) of these amino acids. Students will demonstrate the secondary folding (alpha helices and beta pleated sheets) and tertiary folding of peptides. They will also demonstrate that protein tertiary structure is created when the secondary structures fold and form bonds to stabilize the structure into a unique shape.
During this investigation, students will observe the behavior of Dictyostelium discoideum when exposed to white light in an environment that has a limited food supply. Dictyostelium generally live independently of each other as single-celled amoebae, but when food is scarce, they aggregate to form multicellular mounds. Through several days of observation, students will collect data and graph the results.
In this lesson, students will investigate a sample of pond water and examine a variety of microorganisms under a microscope. Students will choose two organisms to draw and compare them by completing a Venn diagram. They will then work collaboratively to answer a series of discussion questions.
In this lesson, students will be able to identify some ethical, moral, and legal issues surrounding genetic engineering.
