As a teacher of high school or undergraduate Chemistry, you can use this set of computer-based tools when teaching the pH scale, acids and bases, acidification and Environmental Chemistry.
Your current lesson plan can be augmented with this additional classroom/laboratory activity that allows students to understand the pH scale and acidification by analyzing the effect of atmospheric carbon dioxide on ocean chemistry. The activity will also explore the potential effects of climate change on ocean acidification, and the possible impacts of ocean acidification on marine organisms.
Thus, the use of this toolkit allows you to integrate the teaching of a climate science topic with a core topic in Chemistry.

Contents of Toolkit
|1. Micro-lecture (approx. 6 min)||To explain the interaction of atmospheric CO2 with the ocean, and the possible effects of ocean acidification on marine life|
|2. A classroom/laboratory activity||To conduct a classroom/laboratory activity allowing the students to explore and analyze the relationship between the growth of oyster larvae and the chemistry of ocean water by using data from the Whiskey Creek Hatchery in Oregon, USA|
|3. An interactive visualization tool||To foster systems thinking and interactive learning while learning about the pH scale, ocean acidification, and the potential impact of rising atmospheric CO2 levels on marine animals|
|4.Additional resources||To explore the topic in more details|
Using the Toolkit
|1. Topic introduction and discussion||
|2. Play micro-lecture (video)||Now play this micro-lecture (approx. 6 min) provided by the National Science Foundation and NBC Learn (available on Science360 News Service) to explain how carbon dioxide (CO2) affects the pH of the ocean and how an increase in ocean acidification might adversely impact marine animals.|
|3. Classroom/Laboratory activity||Now, explore this topic in an engaging manner through a classroom/laboratory activity:
|4. Interactive Visualization and Activity||Next, use the visualization, “Our Acidifying Ocean,” from the Inquiry to Student Environmental Action (I2SEA) project for an interactive learning session. This tool is available in English, French, German, Portuguese and Spanish.The tools is available at: http://i2sea.stanford.edu/AcidOcean/AcidOcean.htm
Note: This tool requires a Flash player, and therefore, may not play in some browsers. The visualization tool works well in Firefox and MS Edge.
|1. Reading||“What is ocean acidification?” from the European Project on Ocean Acidification (EPOCA): http://www.epoca-project.eu/index.php/what-is-ocean-acidification.html|
|2. Video||Watch the short film, “Ocean acidification: Connecting science, industry, policy and public,” from Plymouth Marine Laboratory: https://www.youtube.com/watch?v=_BPS8ctVW2s&feature=fvst|
