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.
NGSS PracticesEmphasizes Practice 3: Planning and Conducting An Investigation
Could also incorporate Practice 2: Developing and Using Models
NG Sunshine State Standards
STANDARD 18: Matter and Energy Transformation
SC.912.L.18.1 Describe the basic molecular structures and primary functions of the four major categories of biological macromolecules.
5E Lesson OverviewEngagement: 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)

What is it used for in the body?
Examples:
ElaborationCase 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 drinksDescribe 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 bodyPresent their findings at a mock “meeting” with the “editor” of Runners Worldmagazine
EvaluationREVIEW: 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 Frayermodel index card
