fungus or decomposer Take care not to disturb the surrounding environment during your hunt. When you examine items, follow the “rule of six” – do not take one to examine unless there are six more within six feet. This rule generally leaves enough organisms to reproduce. Why should you follow the “rule of six”? __________________________________________________________________ Examine live animal specimens only if you can release them unharmed into the same habitat. Do not examine any vertebrates without your teacher’s approval Your teacher will schedule the time for the hunt. Follow your teacher’s instructions about when to start and stop hunting. When you find an item on your list, enter it on your data table. Observe and make not of other organisms and unusual features in the area in the appropriate column in your data table. Analysis:
Scavenger Hunt Items Something unusual A bone An echinoderm – “spiny skin” and 5 fold symmetry An arachnid – spider A nonflying insect A mollusk – snail or slug An annelid – segmented worm A nematode – round worm A flying insect A pupa (resting stage between a larva and an adult) A larva – immature insect Something round Something soft Something white Something that makes noise A feather (detached from a bird) Conifer Pinecone Seven pieces of trash or litter left by humans Something beautiful Chewed plant part (not chewed by humans) An owl pellet A fungus from a tree A fungus from the ground A gall – abnormal outgrowth of plant tissue ***You must take a good picture of at least 25 items A monocot leaf – has parallel veins in leaf A dicot leaf – “branching” veins in leaf Scat – Animal droppings Something large Something straight A wind dispersed seed An animal dispersed seed 50 of any item A Thorn An example of camouflage A solar energy trap An animal track A frond – large divided leaf (fern) A palmate leaf – leaf resembling an open hand A symbiotic relationship between 2 organisms Flower Seed Something red Something biotic A producer A consumer Something abiotic
Presence in human body (%) Name of chemical element Chemical Symbol Presence 65 Part of water ->in all liquids and tissues, bones, proteins,etc 18 is synonymous with life. Its central role is due to the fact that it has four bonding sites that allow for the building of long, complex chains of molecules. Moreover, carbon bonds can be formed and broken with a modest amount of energy, allowing for the dynamic organic chemistry that goes on in our cells 10 Part of water in all liquids and tissues, bones, proteins,etc 3 is found in many organic molecules, including the amino acids that make up proteins, and the nucleic acids that make up DNA 1.5 is the most common mineral in the human body — nearly all of it found in bones and teeth. Ironically, calcium's most important role is in bodily functions, such as muscle contraction and protein regulation. In fact, the body will actually pull calcium from bones (causing problems like osteoporosis) if there's not enough of the element in a person's diet. Essential for the proper functioning of organs lungs, kidney, liver, thyroid, brain, muscles, heart, bones 1 is found predominantly in bone but also in , which provides energy in cells for driving chemical reactions. 0.35 is an important (meaning it carries a charge in solution). It helps regulate the heartbeat and is vital for electrical signaling in nerves. Found in proteins (enzymes) 0.25 Sulfur is found in two amino acids that are important for giving proteins their shape.
0.15 is another electrolyte that is vital for electrical signaling in nerves. It also regulates the amount of water in the body. 0.05 plays an important role in the structure of the skeleton and muscles. It also is necessary in more than 300 essential metabolic reactions enzymes Traces (.0037) is found in teeth and bones. Outside of preventing tooth decay, it does not appear to have any importance to bodily . Traces (.15) in body liquid is usually found in the body as a negative ion, called chloride. This electrolyte is important for maintaining a normal balance of fluids. Traces (.000017) is essential for certain enzymes, in particular those that protect — the place where usable energy is generated inside cells — from dangerous oxidants. Traces (.006) is a key element in the metabolism of almost all living organisms. It is also found in hemoglobin, which is the oxygen carrier in red blood cells. Half of women don't get enough iron in their diet. Traces (.0000021) is contained in vitamin B12, which is important in protein formation and DNA regulation. Traces (.0001) is important as an electron donor in various biological reactions. Without enough copper, iron won't work properly in the body. Traces (.0032) is an essential trace element for all forms of life. Several proteins contain structures called "zinc fingers" help to regulate genes. Zinc deficiency has been known to lead to dwarfism in developing countries. Traces (.000019) is essential for certain , including several Unlike animals, plants do not appear to require selenium for survival, but they do absorb it, so there are several cases of selenium poisoning from eating plants grown in
soils. Traces (0.000013%) is essential to virtually all life forms. In humans, it is important for transforming sulfur into a usable form. In nitrogen-fixing bacteria, it is important for transforming nitrogen into a usable form. Traces (.000016) is required for making of thyroid hormones, which regulate metabolic rate and other cellular functions. Iodine deficiency, which can lead to goiter and damage, is an important health problem throughout much of the world. Traces (0.0000024%) helps regulate sugar levels by interacting with insulin, but the exact mechanism is still not completely understood. minimum traces 13) Which elements is water made of? ___________________________ 14) What is the most common mineral in the body? _____________________ 15) What does ATP do in our cells? ____________________________________________ _____________________________________________________________________ 16) What is an electrolyte? __________________________________________________ 17) What is the function of Fluorine? _________________________________________ ____________________________________________________________________
