Mississippi Science MAQ.5.6
The Standard
- MAQ.5
- Students will explore the biodiversity and interactions among aquatic life.
Enrichment: Research, analyze, and communicate historical and current methodologies for measuring primary productivity. Use an engineering design process to design and develop improvements to measure primary productivity (e.g., the light and dark bottle method and satellite data). *

What This Standard Means
What Students Need to Do
- Students research early light and dark bottle studies and current satellite chlorophyll maps. They compare what oxygen readings and ocean color reveal about food production in water. They design, test, and revise a way to improve a measurement.
What Mastery Looks Like
- They calculate net and total photosynthesis from clear- and dark-bottle oxygen readings. They explain why satellite chlorophyll maps need checks against water samples. They share trial data and revise their design based on the results.
Common Misconceptions
- Students may treat oxygen gained in a clear bottle as all the oxygen made, forgetting that organisms also use oxygen. They may think a dark bottle shows no activity, or that a greener satellite image directly measures photosynthesis.
How to Assess It
- Exit ticket: A clear bottle gains 2 mg/L oxygen and a dark bottle loses 1 mg/L over the same hour. Calculate total photosynthesis, explain why a satellite chlorophyll map cannot confirm that rate, and name one measurement change you would test.

Ways to Teach It
Fill clear and foil-wrapped bottles with pond water, place them under one lamp, and use a test kit to compare dissolved oxygen before and after.
Give students an early bottle-method description and a current satellite chlorophyll map; ask them to write one limit of each method.
Give teams cards with starting and ending oxygen readings for clear and dark bottles; score correct net production and respiration calculations.
Use a satellite map of a coastal bloom to choose two sampling spots, then plan bottle tests to check the map.
