2. Cyborgs are here!
...eriod Procedure 1. Survey the class for examples of the uses of robots and robotics. Discuss the effectiveness of using robots. 2. Have students read the CNNfyi.com article, "Cyborgs produce breakthroughs, questions," and ask the following: What is a cyborg? Describe the research conducted with the lamprey eel. Do you think the eel is still "alive"? Explain your answer. What is the significance of the eel brain's ability to adapt in its effort to locate light? How do you think this research will help scientists learn more about the human nervous system? Why do scientists believe the structure located...

3. Katherine Hood
...ve entered attached toships or by swimming through the St. Lawrence Seaway. Invader species competewith native species for habitat and food supply and some prey directly onnative species. In this activity, students will make some simple puppetsof four invader species: zebra mussel, white perch, sea lamprey and Bythotrephescederstroemi (B.C.). With a little imagination and creativity, childrenand teachers can create simple puppets. The following are suggestions: Procedure: 1. Construct Zach the zebra mussel A. Have the students color a paper plate the way a zebra mussel looks. Showthem a picture of a z...

4. Vertebrate Dioramas
...f a partner, is to: 1. choose a representative organism from the vertebrate group that was given to you by your teacher; 2. use the reference books, magazines and newspapers to research the representative vertebrate group and choose one representative organism from that group (example: jawless fish-lamprey); 3. examine the organism and try to determine its ancestral form (example: Hemicyclaspus -lamprey ( found in the early Devonian period); 4. create a diorama. (a) divide the length of the board into three parts. Part I (the extreme left) is the ancestral form of your organism in a three-dimensional...

5. Awesome Osmosis
...cells that help to put ingested salts back into the environment. Teleosts also have highly developed kidneys and excretory systems. Sharks, Skates, and Rays: The main form of osmoregulation in sharks, skates, and rays is a specialized salt excretion gland (such as that found in the spiny dogfish). Lamprey: The lamprey has osmoregulatory mechanisms similar to those of marine teleosts. Sea Turtle: The sea turtle, like other reptiles, has specialized salt glands that excrete salt. The shell also provides a barrier to the loss of water to the hypertonic environment. Marine mammals: Excretory organs are d...

6. Life forms
...from the Simpsons video. In this video, Bart brings a frog to Australia. The frog then goes on to change the ecosystem around them. 2. The class will the discuss what types of things have been brought to America and reshaped both our Ecosystem, and how we have lived. Examples include: AIDS Bees Sea Lamprey 3. The students will then watch part of the video "The Swiss Family Robinson." In this video, the family introduces new animals to a ecosystem. 4. Using these two movies, the students will fill out the worksheet on the introduction to new plants and animals. EXTENSION: The lesson can be lengthened b...

7. Freshwater Sharks Bite Children at 35th Beach. A Play
...et it. As a microbiologist I think I HAVE FOUND ALL of the ANTIBODIES in a shark THAT PREVENT CANCER from growing. As a marine biologist I have been researching for these antibodies that their bodies make and I'm trying to synthesize them. Pro shark. I am an Ecologist. The previous invasions of the lamprey eel and the zebra shell mussels haven't done any appreciable damage. Let's wait and see, the cures might pollute the water. In fact, the last invasion is clearing up not only the Great Lakes, but also the Mississippi River. And, it is providing a possible new food source, for certain fish, so the ze...

8. "Using Cichlids To Demonstrate the Effects of Human Activity On Ecosystems"
...ffects of man's activities on the homeostatic balance. This teaching unit is then used to develop further discussions and possible activities centered on the Great Lakes and our state's active participation in the management of the lakes. We particularly emphasize the effects of exotic species (sea lamprey, zebra mussel, spiny water flea, round goby, and ruffe) on our lakes. There were three support laboratory activities that coordinated with this project. At FHS we have a 100, one 60, and two 20 gallon fish tanks with breeding populations of cichlids from Lake Victoria. The students are responsible f...

9. Lesson: Molecular Biology & Phylogeny
...of four, and share the following task with your partners. You will be provided with a chart (Fig.36.2) showing the amino acid sequence in a protein that is homologous for the 20 organisms shown, including six of the seven organisms already studied (data on this protein is not available here for the lamprey). The name of the protein is Cytochrome-c. It is an enzyme that is important in the breakdown of food molecules by a cell. It helps release the energy in food molecules so that it can be used by the cell. Each amino acid is represented by a unique letter in the chart. Compare the sequence of amino a...

10. Leadership and Moving Mountains
...oftly as the innumerable passes he made to teammates in Edmonton, LA, St. Louis, and New York. If Gretzky gradually nudged Canadians towards the realities of modern, professional sports, then Marilyn Bell quite suddenly shoved aside traditional notions of feminine frailty altogether. She feared the lamprey eels and the darkness; and yet, what she would change were a nation's attitudes towards the strength and stamina of women athletes. When Marilyn Bell, a sixteen-year-old grade 12 student at Toronto's Loretto College School, launched her 1.6 metre, 54-kilogram body into the cold waters of Lake Ontari...
