In this outdoor archaeology activity, learners use mathematical skills and scientific inquiry to generate and process information from their own excavation site.

How do scientists measure how clear or murky water in a lake is? How does water clarity (clearness) affect what lives in the lake?

In this activity, learners will explore engineering to construct an insect collecting tool (insect aspirator). The pooter uses suction to safely collect smaller insects that nets miss or may injure.

In this activity, learners are challenged to build a bird feeder using recycled materials from home and are encouraged to problem solve during the extensions.

In this activity, learners will make seed orbs to grow new trees and plants. Learners will explore ecology and life cycles as well as stewardship through this activity.

In this activity, learners will take a step back and learn the history of the land they live on, and the people who used to live on it.

In this international citizen science activity, learners measure their night sky brightness and submit their observations into an online database.

This activity (located on page 3 of the PDF) is a full inquiry investigation into bird behaviors.

This activity (located on page 3 of the PDF under GPS: Cave Swallows Activity) is a full inquiry investigation into bird behaviors.

In this field study, learners discover how to collect data in the field and how their efforts can help certain animals, specifically, amphibians.
