In this exercise, students will explore how a single alteration in the amino acid sequence of the hemoglobin protein results in sickle cell anemia.
In this lesson, students examine how evolution has been scientifically explained historically. In doing so, students will read and analyze the arguments and theories set forth by three historically significant scientists: Jean Baptiste Lamarck, Alfred Russell Wallace, and Charles Darwin.
Students learn how the code on a strand of DNA can be used to make a protein. Each section of the tutorial includes quiz questions that can be answered and then printed at the end of the activity.
In this lab activity, students will investigate the movement of different materials across the cell membrane of a raw egg once the egg shell has been dissolved in vinegar. Students will develop an independent investigation in which they will choose a liquid that will re-hydrate the egg that has been dehydrated.
In this experiment, hydrogencarbonate indicator is used to show the concentration of carbon dioxide in the environment of aquatic animals and plants. Over a 24 hour period, students will explore which combinations of plants and animals make a stable ecosystem in light or dark conditions.
This lab activity is designed for students to gain a general understanding of the characteristics of enzymes, their function and susceptibility to denaturing when exposed to a variety of environmental factors. In this activity, students will use pineapple juice as an enzyme and Jell-O as a substrate to illustrate an enzyme/substrate complex. The initial guided procedure will allow students to discover that the processing of food, specifically canned pineapple, will denature the enzymes and render them useless. The lab extension questions allow students to design and conduct two additional investigations that focus on the behavior, function and the effect that environmental factors have on enzyme activity. The environmental factors that students can explore include: temperature, pH, microwave radiation and detergents.
This brief video shows the wide range of reproductive adaptations and strategies that contribute to the success of common invertebrates in the ocean. Discussion/assessment questions and suggested supplemental resources are included.
This short video lesson gives an overview of Mendelian genetics. Assessment and discussion questions, as well as links to additional resources, are included.
Students to read detailed scientific passages and explain how an understanding of specfifc icefish adaptations might lead to a treatment or cure for human disorders, such as osteoporosis and anemia.
