Interpret & Communicate

Topic (36) Construct an explanation about amino acids forming from carbon, hydrogen and oxygen. (HS-LS1-6)

The last step of most scientific investigations is reporting the results.

When scientists communicate their findings, they add to the body of scientific knowledge, and that’s how science advances. When scientists communicate about their research, they may also get useful feedback from other scientists. For example, comments from other scientists might help them improve their research design or interpret their findings in a different way.

Other scientists can also repeat the research to see if they get the same results. A typical scientific sequence is to measure and observe (topic 34), create a model of the information (topic 35), then interpret and communicate the results (this topic).

STUDENT CHALLENGE: This topic combines two concepts. The first concept deals with scientific data collection and reporting. The second concept is about amino acids. Your job on this topic is to explore data related to amino acids and decide whether certain statements are true or not true. Someone, somewhere, at some time has done TONS of research about amino acids.

Day 2 – Virtual Textbook
Research Assignment

Based on information presented in this topic – and your own research – does data support any of the following statements? In what way, if so? At least one of these statements seems to be true based on data. At least one statement seems to not be true based on data. At least one of these statements is possibly true, but not definitely true based on data.

  • Glutamine in banana trees is required for the trees to bear fruit.
  • Histidine decreases allergic reactions.
  • Serine makes dogs calmer.
  • Valine levels in humans increase as altitude increases.

Make a table with the following column headings: (1) Name of Amino Acid (2) Chemical Formula (3) #Carbon (4) #Oxygen (5) #Hydrogen (6) #Other

Select six from the list below and complete your matrix.

aspartic acid
glutamic acid
