Adolescent Sleep
|
|
The purpose of this lesson is to discuss, summarize, and express alternative positions regarding a study on adolescent sleep. There are certain thinking skills associated with science, mathematics, and technology that young people need to develop during their school years. The ideas in the central benchmark emphasize the need for education to prepare students to make their way in the real world, a world in which problems abound in the home, in the workplace, in the community, on the planet. Moreover, in their interactions with society, science and technology create the context for many personal and community issues. (Benchmarks, p.282) In this lesson, students will examine the arguments for and against changing the school start time for high school students, based upon the findings of a scientific research study.

Aquatic Zoology
|
|
On earth, some of the unicellular animals evolved into multicellular forms. As animals cannot make their own food, multicellular animals, even primitive ones, had to find ways to capture nourishing chemicals. This lesson will give students some ideas on how to design the aquatic animals for their planet.

Bouncy Blubber
|
|
This Weekly Science Update, found on the Science NetLinks website, focuses on the form and functions of marine mammals' blubber. Through reading and research, students discover that blubber is a good deal more complex and serves far more purposes than scientists had once believed. Using a 90-second net-radio format, Weekly Science Updates are mini-lessons designed to introduce and investigate various scientific concepts.

Can You Taste It?
|
|
In this lesson, students diagram the areas of taste reception on the tongue. This activity will single out one section of the tongue at a time. Students will map out the tongue by testing their taste buds. They will try four different solutions. Each one should affect one part of the tongue more than any other. By knowing the taste, they can determine where their sweet, sour, bitter, and salty taste buds are.

Cancer Risks
|
|
The purpose of this lesson is to describe environmental and hereditary factors that increase the chance of developing cancer. Research shows that after education, students hold the misconception that human beings have cells inside of them, rather than being composed of cells themselves. As a result, students might perceive cancer as a group of foreign cells that are 'invading' their normal cells, instead of knowing that cancer cells are simply normal body cells that have mutated. Students might also be unaware of the fact that all cells in every human being have the potential to become cancerous. Thus, students might think that cancer is a disease that you 'catch' from others and the environment. In this lesson, students read two articles, one from a newspaper and one from a magazine, which describe communities in the United States that have been affected by high rates of cancer. The alleged causes for these cancers are environmental pollutants and industrial chemicals. Students will then read information about cancer written by scientists which describes hereditary factors that contribute to cancer development. Finally, students will read a report by the National Center for Policy Analysis, which examines some misconceptions about cancer. At the end of this lesson, students should be able to distinguish that there are both environmental and hereditary factors, which influence a person's likelihood in developing cancer. Thus, it is difficult to say that any one thing is the cause of all cancers.

Chemical Methods of Control
|
|
A wide variety of chemicals called antimicrobial agents are available for controlling the growth of microbes. For example: 1. Chemotherapeutic agents, including antibiotics, are used internally. 2. Disinfectants are chemical agents used on inanimate objects to lower the level of microbes present on the object. 3. Antiseptics are chemicals used on living tissue to decrease the number of microbes present in that tissue. One method of measuring the effectiveness of a chemical agent is to determine its zone of inhibition. In the agar diffusion method, one species of bacteria is uniformly swabbed onto a nutrient agar plate. Chemicals are placed on paper disks. These discs are added to the surface of the agar. During incubation, the chemical diffuses from the disk containing the agent into the surrounding agar. An effective agent will inhibit bacterial growth, and measurements can be made to quantify the size of the zones of inhibition around the disks. The relative effectiveness of a compound is determined by comparing the diameter of the zone of inhibition with values in a standard table.

Coping with Changes
|
|
The purpose of this lesson is to understand how the nervous system allows us to learn, remember, and cope with changes in the environment. In grades 3-5, students start viewing the body as one whole system, as one whole organism. In the 6th grade and up, students should start to understand how organs and organ systems work together. For instance, the brain is part of the nervous system and works in conjunction with neurons (cells). The nervous system works with all other body systems, such as the musculoskeletal system. The activities in this lesson introduce the nervous system, both in parts and as a whole. By learning about the whole system, students will understand that the brain, spinal cord, and nerve cells are at the root of all other body functions.

Crayfish Reflexes

Creating Coacervates
|
|
Students mix a carbohydrate solution with a protein solution, adjust the pH, and view coacervates: amoeba-like objects, which change shape, flow, merge, divide, form "vacuoles", release "vacuole contents", and show other life-like properties.

Deaf Manatees
|
|
This Weekly Science Update, found on the Science NetLinks website, attempts to shed light on the problem of the injury of manatees through collisions with powerboats in the Florida Everglades. Students learn about the results of test performed by researcher Edmund Gerstein, who discovered that manatees are in fact deaf, rather than dumb, as had been previously theorized. Using a 90-second net-radio format, Weekly Science Updates are mini-lessons designed to introduce and investigate various scientific concepts.

Demonstrating An Epidemic
|
|
Epidemiology is the study of disease origin and transmission.This experiment allows students to experience a small scale "epidemic," demonstrating the ease with which disease organisms are spread, and enables the student to determine the originator of the "epidemic." Students will transfer live bacteria by hand contact, then transfer an inoculum to a nutrient agar plate for 24 hour incubation. After incubation, plates are observed for growth of the microbial agent. By arranging the plates in the order of hand contact, it can be determined what individual received the original contaminant and started the "epidemic," which individuals transferred the organism yet did not grow it out (carriers), and how dosage, or amount of contamination, affects getting a disease. It must be pointed out that in an actual epidemic a contaminated individual could feasibly contact many others and not just one as demonstrated in this procedure and that the organism will multiply in each host before being passed on. Other means of microbial transmission (air, water, body fluids, fomites) may also be discussed. (Fomites are inanimate objects such as combs, pencils, etc. which may carry microbes on the surface.)
