LandTalk is a citizen science and environmental history project that documents through interviews

how local landscapes change over time. Its goal is to provide an opportunity for conversations between generations, and a chance to learn from observers about changes they have seen.

Land Talk is a great exercise to do with students of most ages. Several lesson plans, based on the Next Generation Science and Core Curriculum standards, have been developed to complement the project. While these plans target standards for specific grade levels, they are intended to be adapted to other grades and subjects.

This 3-part interactive and virtual lab activity examines the life cycle of the sea urchin, and how the increasing acidity of the ocean affects their larval development.

Interactive online tutorial about growing urchin larvae in a lab setting. Students manipulate data and are led through a lab-based situation. There is a module on ocean acidification. Lesson plans can be downloaded from website.
