Lesson 5b – Online Data and Supplemental Evidence (pre-2018 version)


The purpose of this lesson is for students to model the scientific process – which includes the experimental bench work they are completing in Lesson 5a and the collaboration and connection to others’ research.  This lesson gives students the time and resources to learn from the work being completed by scientists and through their online contributions.

Wet Lab Simulations

  • Virtual Sea Urchin Lab (Bad Acid) – Our Acidifying Ocean Website:  http://virtualurchin.stanford.edu/AcidOcean/AcidOcean.htm
  • Netlogo Simulation – Use this simulation model to have students get a feel for how carbon, pH, silica-shelled diatoms, and coccolithophores might impact and affect each other in an ocean system.
    • You must first download NetLogo.  Follow the Download instructions and prompts on the NetLogo website. The program is free, but registration is necessary.
      • Click the appropriate download button for your machine.
      • Save the file to your desktop or program folder.  If you have find you have issues running any files, you may need to save all needed net logo files and programs to one folder.
      • Run the NetLogo Installer when prompted.  Allow the Wizard to guide you through the process.
    • Download this Ocean Acidification.nlogo file and save it in your NetLogo folder.  You can download the file by right-clicking the link and selecting “Save As.”  Save it in the NetLogo folder on your Desktop or in the Models subfolder.
    • View the contents of the program folder and launch NetLogo.
      • You will find there are many files and programs to choose from.
      • Scroll through to find the main, non-3D version of NetLogo.  Double click to launch that NetLogo program.
    • Once open, select the File tab, then click the Open option.  Select to open the Ocean_Acidification.nlogo file that you previously saved.
  • From the open model, click the Information tab to read the instructions and run the model.

Finding Current Data from around the Globe

Mesocosms – Click here for a word document that contains compiled information on mesocosm studies and background information. Students can use this information to further explore how they might adapt their experiment and/or what supplemental data they can gather that connects to the subsystem they are studying.

What the Past Tells Us

The past tells us a great deal about current conditions in the ocean. Scientists use reliable data from the past on trends and rates of change to make predictions about our future.  Here are a few marine education resources on using our past to understand the future.
