This fun hands-on astronomy activity lets learners use star maps (included) to find constellations and to identify stars with extrasolar planets (Northern Hemisphere only, naked eye).
Linkages
Source Institutions
This design challenge is an open-ended exploration of linkages, a group of parts connected by hinges, and the types of motion they can create.
Caution! Wildlife Crossing
Source Institutions
In this design challenge, learners use their creativity and imagination to design and test a wildlife crossing for their favorite animal.
Parachutes
Source Institutions
In this activity, learners will investigate air and gravity through the use of various fabrics by through them in the air. Activity includes step-by-step instructions and extension ideas.
Sound Charades
Source Institutions
