NGSS HS‐LS1‐6
Construct and revise an explanation
based on evidence for how carbon,
hydrogen, and oxygen from sugar
molecules may combine with other
elements to form amino acids and/or
other large carbon‐based molecules.

SC.912.L.18.1 Describe the basic
molecular structures and primary
functions of the four major categories
of biological macromolecules.
5E Lesson Overview
Engagement: video clip – “Molecules Gone Wild (Bio
Style)” and pre‐test
Exploration: lab activity – “Biomolecules in My Food”
Explanation: directed note‐taking in a foldable
Elaboration: case study – “A Can of Bull? Do Energy
Drinks Really Provide a Source of Energy?”
Evaluation: post‐test (same as pre‐test)

Elaboration
Case Study: “A Can of Bull? Do Energy Drinks Really
Provide a Source of Energy?”
Students work in groups as members of teams of
journalists working for Runner’s World magazine
Research ingredients found in 4 popular energy drinks
Describe what they do for the body (proteins, amino acids,
carbohydrates/sugars, etc.)
Evaluate the marketing claims of the product based on how
its ingredients affect the human body
Present their findings at a mock “meeting” with the
“editor” of Runners World magazine
Evaluation
REVIEW: Use biomolecule
vocabulary cards for student
review
Students complete a multiple
choice post‐test (same as pre‐test)
Individual student data should be
compared to pre‐test scores
Students also complete a Frayer
model index card
