Biological Molecules- Layered Curriculum
C Layer /10 (K/U)
You may choose a combination of the tasks below to become familiar with the biological molecules, their structures and functions, and the
reactions associated with them. Choose a wide variety of activities from all of the categories. Your points must add up to 100, and will be
checked by your teacher in class. You may receive up to 25 points a day over four days, so plan and use your time wisely.
Carbohydrates
5 points
Lipids
5 points
-build two glucose molecules using the model kit then show the
formation of the disaccharide in front of your teacher. Be ready to
identify the disaccharide and the linkage.
-build a glucose and galactose molecule using the model kit then show the
formation of the disaccharide in front of your teacher. Be ready to
identify the disaccharide and the linkage.
-build a ring glucose molecule out of craft supplies (remember to label the
carbons)
-answer p. 38 #2, 3, 5
-build glycerol and 3 different fatty acids then show the formation of a
triglyceride using the model kits
-build and label a fatty acid using craft supplies
Watch the Ted Ed Lesson “What is Fat” and complete the Think
questions.
-create a table summarizing the four types of lipids, their structures and
uses
-create a table comparing and contrasting saturated and unsaturated fatty
acids (their structures, sources, and health effects)
-answer p. 38 #6, 7, 8
10 points

-create and perform a public service announcement about what dietary
fibre does in our intestinal tract and the importance of it in humans.
10 points
Proteins
5 points
Nucleic Acids
5 points
-build isoleucine and glycine using the model kit, and join them to create a
peptide bond
-Use figure 4 on pg 42 to draw how four amino acids join together to
form a polypeptide
-build and label a generalized structure of an amino acid out of craft
supplies
-create a chart summarizing the four levels of protein structure
-answer p. 47 #1-5
-draw and label a nucleic acid in detail (at least with a total of 4 subunits,
double-stranded, and label all bonds)
-build and label a nucleotide out of craft materials
-create a summary of DNA, RNA, and ATP, drawing and explaining their
structures, functions, and any functional differences
-answer pg. 47 #8, 9, 10, 11
10 points
-read and summarize textbook p. 39-44
-research the essential amino acids. List these amino acids and identify
dietary sources for each. What is the best way to ensure that all the
essential amino acids are part of your diet?
-read and summarize textbook p. 33-37
-conduct online research to identify the essential fatty acids. Write a brief
description of each, including dietary sources.
10 points
-read and summarize p. 45-47
-watch the TED talk “James Watson on how he discovered DNA” and
take notes
All
5 points
-create flashcards and memorize the following vocabulary terms: dehydration synthesis/condensation reaction, hydrolysis, isomer, saturated,
unsaturated, polyunsaturated, amide linkage, peptide bond, glycosidic linkage, phosphodiester bond, ester linkage, adenosine triphosphate,
hydrophobic, hydrophilic, anabolic, catabolic, starch, glycogen. You will be randomly tested on any of these terms.
10 points
-write a short story for children about the importance of a balanced diet (at least 8 pages, 2-3 sentences per page, with pictures)
-create a menu of a balanced diet for a day, and explain why your choices are appropriate
-draw a detailed cell membrane and label the different macromolecules and their functions
-create a detailed cell membrane out of craft materials and label the location of the macromolecules and their functions
-create a summary/review sheet (1-page: in the form of a table, chart, or paragraph or point form summary) of the structure and function of all the
macromolecules and post it online under the “review” tab
-write a review poem/rap/song (at least 20 lines) and perform it for your teacher or for the entire class
15 points
-create five multiple choice and two short answer review questions and post them under the “review” tab online with the correct answers
B Layer /20 (T/I)
In groups, you will research the chemical indicators for the following: simple sugars, starch, lipids, or proteins. You will design a lab
procedure to test for the presence of your molecule in a variety of foods of your choice.
You will be given one class period to test out the reagents and equipment and form your procedure, which you will submit the following
class with at least one reference. After your teacher has checked the procedures, a later day will be used to carry out your lab and collect
results.
A Layer /30 (Comm + Making connections)
You will complete a lab write-up (as instructed in class) and submit it for communication and making connection marks.
