We created a checklist of suggested tasks (see below) to help make this project less time-consuming. However, this list cannot […]
The Conical Pendulum
An Experiment in Circular Motion and Centripetal Acceleration The conical pendulum lab allows students to investigate the physics and mathematics of uniform circular motion. A motorized, plastic plane* is suspended from a thin string and “flies” in a circular path with a constant speed. The plane and the supporting string trace a conical pendulum. Students […]
Webinar Series: Making Sense of Three-Dimensional Science
Join us for series of webinars that will help you teach and assess new science standards. More than a decade after the release of A Framework for K-12 Science Education, there is still confusion and misunderstanding about three-dimensional learning and assessment that is the foundation of the Next Generation Science Standards (NGSS)*. The Smithsonian Science […]
Free Dissection Guides and Resources
Help for teachers new to (or returning to) dissection labs. Dissecting preserved specimens plays an important role in biology education–but teaching dissection labs for the first time can be stressful. Our free guides and resources can take some of the stress out of teaching your first (or first in a while) dissection lab. Why is […]
12 Tips for Maintaining Safe Distance in College Labs
Use these reminders and recommendations as you plan your socially-distanced labs. Creating and maintaining social distance in your lab shouldn’t be a pain point.
