Acknowledgments -- Introduction -- How to use this book -- Science projects -- Under your feet: projects in soil. Homemade topsoil: making nutrient-rich topsoil - A slice of life. Comparing the thickness of soil to the dominant plant species - Feed me, I'm hungry: nitrogen content in soil where carnivorous plants live - It's leaking in: percolation of lake-bottom soil - Rotten to the core: comparing amount of organic material in lake-bottom soil to forest soil - Winter homes: temperature differences between lake surfaces and bottoms in winter - Pile driver: the grabbing ability of sand -- Ecology: projects in habitat and life cycles. Cover up: determining relationships between habitat size and the number of organisms living there - Longer in the womb, later in the tomb: comparing organism gestation period with longevity - "Wood" it burn well: comparing tree decomposition with position - Hair helps: animal hair as a natural thermal insulator - Blubber is beautiful: animal fat as a natural thermal insulator - Chicken feed is for the birds: animal populations and food supply - Who comes to drink: organism attraction to sweetness -- Pests and controls: projects in weeds and insects. Insect picnic: developing insect pest lures - Nighttime flyers: the effect of heat and light on flying insects - Window box protection: testing marigolds to control insect pests - Scare bottles: objects in motion to repel bird pests - Crabby grass: varying watering levels as natural weed control - Netting your food: determining the number of insects trapped in spider webs - Nature's herbicide: using acid from black walnut trees to prevent weeds -- Recycling: projects in resources and conservation. Garbage away!: determining the amount of daily unrecyclable household trash - Rip it, tear it, decompose it: comparing the decomposition rate of paper made from recycled paper to standard paper - My old shirt: the affect of discarded clothing on the environment - How does your garden grow: evaluating constructed from man-made substances - It's in the bag: aerobic and anaerobic organisms that aid in decomposition - Trees please (many organisms): trees naturally recycle themselves - Making gardens out of ant hills: evaluating the nutrient content of ant hills -- Waste products: projects in decomposition. Buried but not forgotten: decomposition of common materials - Plastic graveyard: comparing decomposition of plastics - Above or below: decomposition above and below the ground - Preserving our goods: developing a defense against iron rust - Soak it up: soaking solutions for wood preservation - Compact campfire: making fuel bricks from tree litter - Soap box opera: determining the ratio of a container to the quantity -- Indoor environment: projects in microscopic organisms. My walls are weeping: locating humid areas in a home - Air garbage: scattering of particulate matter by vacuum cleaners - Dusting the air: airborne particulate matter in the home - No noise is good noise: shrubs as natural sound barriers - Lead into hot water: lead in dinnerware - No smoking area: detecting particulate matter in cigarette smoke - The nose knows: how odors affect people -- Man affects the environment: projects in mankind and the environment. Outdoor air conditioning: changing the reflectivity of the Earth's surface affects temperature - Particular particulates: airborne particulate matter blocks sunlight and affects temperatures on Earth - Every litter bit burns: evaluating moisture content in ground-tree litter for retarding forest fires - Clean up your act : water purification - Flying fly ash: chimney air polluters - Oil and water don't mix: water pollution by petroleum products - Group rates: mass transit efficiency -- Resource list: a list of mail-order suppliers of laboratory materials -- Glossary -- About the authors -- Index. Suggests forty-nine projects in environmental science, suitable for the classroom or a science fair. |
