We are going to ask the question: how does moving the fulcrum point effect the distance a nickel can fly?

balance the ruler so there is an equal length on both sides of the fulcrum (at the 6” mark).
put a nickel at the one inch mark on the ruler. record your observations in the data table.
keep the nickel at the 1” mark. drop a quarter on the end of the opposite end of the ruler from about 12 inches in height. measure the distance from the end of the ruler to where the nickel lands. record your results.
repeat this 3 times.
now move your fulcrum to the 9 inch mark and repeat steps 2-4.
now more your fulcrum to the 12 inch mark and repeat steps 2-4. which causes the nickel to fly farther? which takes more force?

Match the descriptions / definitions with the term they best describe 1. three dimensional relationship of the different polypeptide chains in a multisubunit protein or protein complex 2. common folding pattern in proteins in which a linear sequence of amino acids folds into a right-handed coil stabilized by internal hydrogen-bonding between polypeptide backbone atoms. 3. the amino acid sequence of a protein 4. a region on the surface of a protein that can interact with another molecule through noncovalent bonding. 5. three-dimensional arrangement of alpha-helices and beta-sheets within a single polypeptide, typically stabilized by a variety of noncovalent bonds, including ionic and hydrogen bonds, and nonpolar interactions / hydrophobic force. 6. the chain of repeating carbon and nitrogen atoms, linked by peptide bonds, in a protein. 7. common structural motif in proteins in which different sections of the polypeptide chain run alongside each other and are joined together by hydrogen bonding between atoms of the polypeptide backbone. 8. portion of a polypeptide chain that has a discrete tertiary structure of its own and can often fold independently of the rest of the chain 9. regular local folding patterns in a protein, including alpha-helix and beta-sheet a. primary structure b. beta-sheet c. protein d. coiled-coil e. polypeptide backbone f. secondary structure g. side chain h. tertiary structure i. binding site j. alpha-helix k. quaternary structure l. protein domain
