Lab: Density of Solids Assignment: Lab Report
1.) What is the purpose of the lab, the importance of the topic, and the question you are trying to answer?
2.) What is your hypothesis (or hypotheses) for this experiment?
3.) What methods are you using to test this (or each) hypothesis?
4.) Locate the data and observations collected in your lab guide. What are the key results? How would you best summarize the data to relate your findings?
5.) Do you have quantitative data (numerical results or calculations)? Do you have qualitative data (written observations and descriptions)? How can you organize this date for your report?
6.) What do the key results indicate?
7.) If you constructed graphs, what trends do they indicate in your data?
8.) Were there any problems with the experiment or the methods? Did you have any surprising results?
9.) What do the results tell you about your hypothesis(es)?
10.) How do the data support your claim above?
11.) If you could repeat the experiment and make it better, what would you do differently and why?

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
