Lesson 4 – Planning Cohesive Experiments

Course:  Life Science, Integrated Science, STEM, BioChem, Marine Science

Unit:  Ocean Acidification, Ecology, Biogeochemical Cycling


See Standards Addressed for all NGSS, WA State (Science, Math and Literacy), and NOAA Ocean Literacy Education Standards Connections.  In addition to the aligned objectives linked above, for this lesson, here is a breakdown of:

What Students Learn:

  • Systems scientists work together (collaborate) to build off of each other's experiments to achieve enough data and experimental evidence to understand complex relationships.  
  • Preparing and planning for experimentation is required for successful implementation of research.  
  • Experimental ideas often come from the needs and passions of humans.  
  • Systems thinking is a useful technique for understanding complex situations.
  • Systems thinkers use systems diagrams as tools of their trade. 
  • There are many types of systems; these can be represented in many ways and have many different properties and forms, such as being in equilibrium, containing balancing loops, reinforcing loops, etc. 

What Students Do:

  • Students collaborate to design experiments.    
  • Students refine and narrow a question based on a large, big picture question.
  • Students build their hypotheses, make predictions, design how they will measure outcomes, list needed equipment/materials, and complete procedural flow charts and protocols.
