Hands-on science (no lab required).Check out these hands-on experiments after you've read "Good Vibrations" (p. 15) and "Paradise Lost Paradise Lost Milton’s epic poem of man’s first disobedience. [Br. Lit.: Paradise Lost] See : Epic " (p. 8). They're fun and foolproof! FEEL THE RHYTHM In "Good Vibrations" you learned that elephants Elephants Slang for large institutions that make trades in very high volumes. Notes: Examples of elephants are mutual funds, pension plans, banks, and insurance companies. One elephant trade can dramatically move the market price for a security. communicate by transmitting sound waves through the ground. Discover how sound travels through different mediums. YOU NEED: 4 pieces of kite string (35 cm, or 14 in., each) * metal hanger * paper * pencil TO DO: 1. Tie the end of one string to one end of the horizontal part of a metal hanger. Tie a second string to the other end of the horizontal part of the hanger. 2. Wrap the end of one string around an index finger three times. Wrap the second string three times around your other index finger. Make sure both strings are the same length. 3. Hold the strings so the hanger dangles freely in front of you. Gently swing the hanger so it bumps bumps a term used to describe a variety of papulonodular dermatoses in horses, including 'heat bumps', 'feed bumps', 'protein bumps', 'wheat bumps' and others. No specific disease or etiology has been assigned to the term and veterinary dermatologists wish it would disappear from use. against the side of your desk. Record what you hear (for example loud/soft sound, high/low pitch). 4. Now, place the tip of one index finger into each ear (not too far!) and lean over so the hanger dangles freely. Again, gently swing the hanger so it bumps against the side of your desk. Record what you hear, and what you feel in your ears. CONCLUSIONS: Was the sound loudest when your fingertips "Fingertips" is a 1963 number-one hit single recorded live by "Little" Stevie Wonder for Motown's Tamla label. Wonder's first hit single, "Fingertips" was the first live, non-studio recording to reach number-one on the Billboard Pop Singles chart in the United States. were in or out of your ears? Which case best describes the way sound reaches an elephant's feet? Explain. SCHOOL YARD BIODIVERSITY biodiversity: see biological diversity. biodiversity Quantity of plant and animal species found in a given environment. Sometimes habitat diversity (the variety of places where organisms live) and genetic diversity (the variety of traits expressed In "Paradise Lost" you read about the amazing a·maze v. a·mazed, a·maz·ing, a·maz·es v.tr. 1. To affect with great wonder; astonish. See Synonyms at surprise. 2. Obsolete To bewilder; perplex. v.intr. plant and animal diversity found in Borneo's rain forests. Conduct a biodiversity survey in your school yard to see which areas have the greatest variety of life. YOU NEED: hula hoop Hula Hoop Noun trademark a plastic hoop swung round the body by wiggling the hips * sheet of poster board * colored markers * small shovel * clipboard A reserved section of memory that is used as a temporary holding area for data that is copied or moved from one application to another using the copy and paste and cut and paste (move) menu options. Each time you transfer something into the clipboard, the previous contents are deleted. and paper (for field notes) TO DO: 1. As a class, look around the school grounds for three different locations to conduct a biodiversity survey (for example, grassy grass·y adj. grass·i·er, grass·i·est 1. Covered with or abounding in grass. 2. Resembling or suggestive of grass, as in color or odor. Adj. 1. area near a fence, area with trees, full-shade area, full-sun area, and so on). 2. Divide into groups of three to four students. 3. Choose a study location for your group. More than one group can work in the same area. 4. Place the hula hoop on the ground at your location. 5. Have one student take notes as the other students list the kinds of plants, insects, and other organisms Organisms See also animals; bacteria; biology; plants; zoology. anabolism Biology, Physiology. the synthesis in living organisms of more complex substances from simpler ones. Cf. catabolism. — anabolic, adj. living inside the hula-hoop plot. 6. Dig a hole (8 cm by 8 cm, or 3 in. by 3 in.) in the plot. 7. Look for insects in the soil. Record your findings. 8. Back in the classroom, use the poster board, markers, and field notes to draw the ecosystem your group observed. Display your group's poster and discuss your findings with the class. CONCLUSIONS: Which location had the greatest biodiversity? Discuss the possible reasons. ANSWERS Feel the Rhythm: The sound was louder when your fingertips were in your ears. That's because sound waves transmit better through a solid (string) than through a gas (air). How it works: When you tap the hanger, it vibrates. These vibrations--sound waves--travel through the air to your ears. When you place your fingertips in your ears, the sound waves travel from the hanger, up the string and into your ears. This was similar to how sound waves travel to an elephant. That's because the waves traveled through a solid (the string and then your fingertips) rather than through the air. School Yard Biodiversity: Answers will vary depending oil locations chosen for the biodiversity study. Look at the number of different kinds of grasses/plants on each poster. Also discuss the variety of animals on the surface and in the soil.
