Through this lesson, students will learn what organisms are affected by ocean acidification by taking on the role of one of the stakeholders affected by ocean acidification and creating poster(s) to address their issue(s). They will then participate in a mock conference to address the affects of ocean acidification and discuss solutions to reduce ocean acidification.

Grades: 7th – 12th Grade
Subjects: Biology / Life Sciences, Chemistry, Earth Sciences, English-Language Arts, Investigation and Experimentation, Life Sciences, Physical Sciences
Topics: Acids and Bases, Chemical Properties and Processes, Chemistry of Living Systems, Environmental Policy
Duration: 10 min Prep + 1 hour Activity + 1 hour Post
Setting: Classroom

Lesson Plan
Stakeholder Cards
Conference Directions

Objectives: Through this lesson, students will:

  • Learn what organisms are affected by ocean acidification
  • Take on the role of one of the stakeholders affected by ocean acidification
  • Create poster(s) to address their issue(s)
  • Participate in a mock conference to address the affects of ocean acidification
  • Discuss solutions to reduce ocean acidification


Stakeholder Cards (classroom set)
Conference Directions Sheet – 1 per group
Poster paper (one per group)
Markers, colored pencils, or crayons (set per group)
6 envelopes with one blank paper taped to the outside and 5 blank papers inside
Scratch paper


calcifier: an organism that builds a calcium carbonate shell or skeleton
calcium carbonate: the basic material of which most marine shells and some skeletons are made
carbon dioxide: a chemical compound composed of two oxygen atoms bonded on either side of a carbon atom. While naturally occurring in our atmosphere, carbon dioxide is also the by-product of the combustion of fossil fuels, emitted from car engines, coal power plants, and other producers of exhaust. Carbon dioxide is a greenhouse gas.
green house gas: gases in the atmosphere that absorb and emit radiation within the thermal infrared range. This process is the fundamental cause of the greenhouse effect.
ocean acidification: the process by which carbon dioxide dissolves in seawater causing a decrease in pH. To learn more, see ‘Teacher Background.’



Create six groups of students, one for each stakeholder group: Organisms, Fishing Industry, Energy Companies, Transportation Industry, Recreation/Travel Industry, and Representatives from the Public.

Print out one set of Stakeholder Cards. Each group will get the card associated with their group. For example, the Fishing Industry will receive the “You are: Representatives of the Fishing Industry” card. *if groups are large, you may wish to print out more than one set so that students aren’t crowded around one card.

Print out Conference Directions Sheet (one per group).

We recommend breaking up the activities so that the first day focuses on preparing for the conference (introduction and creation of poster and presentations), reserving the second day for the actual conference, presentations, and class discussion.

State Schools Chief Tom Torlakson Announces 2017 Finalists for Presidential Awards for Excellence in Mathematics and Science Teaching

Posted: Wednesday, September 20th, 2017

SACRAMENTO—State Superintendent of Public Instruction Tom Torlakson today nominated eight exceptional secondary mathematics and science teachers as California finalists for the 2017 Presidential Awards for Excellence in Mathematics and Science Teaching (PAEMST).

“These teachers are dedicated and accomplished individuals whose innovative teaching styles prepare our students for 21st century careers and college and develop them into the designers and inventors of the future,” Torlakson said. “They rank among the finest in their profession and also serve as wonderful mentors and role models.”

The California Department of Education (CDE) partners annually with the California Science Teachers Association and the California Mathematics Council to recruit and select nominees for the PAEMST program—the highest recognition in the nation for a mathematics or science teacher. The Science Finalists will be recognized at the CSTA Awards Luncheon on Saturday, October 14, 2017. Learn More…

Thriving in a Time of Change

Posted: Wednesday, September 13th, 2017

by Jill Grace

By the time this message is posted online, most schools across California will have been in session for at least a month (if not longer, and hat tip to that bunch!). Long enough to get a good sense of who the kids in your classroom are and to get into that groove and momentum of the daily flow of teaching. It’s also very likely that for many of you who weren’t a part of a large grant initiative or in a district that set wheels in motion sooner, this is the first year you will really try to shift instruction to align to the Next Generation Science Standards (NGSS). I’m not going to lie to you, it’s a challenging year – change is hard. Change is even harder when there’s not a playbook to go by.  But as someone who has had the very great privilege of walking alongside teachers going through that change for the past two years and being able to glimpse at what this looks like for different demographics across that state, there are three things I hope you will hold on to. These are things I have come to learn will overshadow the challenge: a growth mindset will get you far, one is a very powerful number, and it’s about the kids. Learn More…

If You Are Not Teaching Science Then You Are Not Teaching Common Core

“Science and Social Studies can be taught for the last half hour of the day on Fridays”

– Elementary school principal

Anyone concerned with the teaching of science in elementary school is keenly aware of the problem of time. Kids need to learn to read, and learning to read takes time, nobody disputes that. So Common Core ELA can seem like the enemy of science. This was a big concern to me as I started looking at the curriculum that my district had adopted for Common Core ELA. I’ve been through those years where teachers are learning a new curriculum, and know first-hand how a new curriculum can become the focus of attention- sucking all the air out of the room.

Tools for Creating NGSS Standards Based Lessons

Posted: Tuesday, August 29th, 2017

by Elizabeth Cooke

Think back on your own experiences with learning science in school. Were you required to memorize disjointed facts without understanding the concepts?

Science Education Background

In the past, science education focused on rote memorization and learning disjointed ideas. Elementary and secondary students in today’s science classes are fortunate now that science instruction has shifted from students demonstrating what they know to students demonstrating how they are able to apply their knowledge. Science education that reflects the Next Generation Science Standards challenges students to conduct investigations. As students explore phenomena and discrepant events they engage in academic discourse guided by focus questions from their teachers or student generated questions of that arise from analyzing data and creating and revising models that explain natural phenomena.

This month I was fortunate enough to hear about some new topics to share with our entire region. Some of you may access the online or newsletter options, others may attend events in person that are nearer to you. Long time CSTA member and environmental science educator Mike Roa is well known to North Bay Area teachers for his volunteer work sharing events and resources. In this month’s Region 1 updates I am happy to make a few of the options Mike offers available to our region. Learn More…
