Teaching Tips | Science | Pedagogy |
- This video provides background information and images that act as good introduction to a discussion or learning activity about ocean acidification.
- It can be used as stand-alone or in conjunction with the related Lesson Plan.
- The lesson plan and activity are both long and involved, but provide good grade-level appropriate, hands-on experiences. It is possible to parse this activity into several shorter exercises that could be effective. The last two pages of "thought" questions can perhaps be re-purposed for tests or the like; as is, they are not an engaging way to end the lesson.
