Species Survival
How can we protect species in our area?
Students work together to investigate local species that are (or were) native to the area and are now endangered or threatened. Students record findings in field journals and compare their findings with the populations in various ecosystems and habitats around the world. Students research and record information such as the inherited traits, learned behaviors, adaptations, life cycles, and food chains of key species in various habitats and make connections to the local species and habitat they are investigating. Students work together to determine why the species is no longer thriving or surviving and how they might protect or positively affect the species, and then students communicate this information to their larger community.

Marking History, Making History
How can we as historians uncover and share stories about our community?
History is a process of interpretation and perspective-taking. In this project, students research the history of their home community or region and use primary source materials to learn about the experiences and perspectives of multiple community members (e.g., indigenous people, immigrants, colonists, enslaved people, people of different class backgrounds) in relation to particular events. Students use what they learn to document and share the multiple (and sometimes conflicting) histories that coexist in their local community.

Shrinking Our Footprint
How can we use data to reduce our families’ impact on the environment?
