GLOBE Grandma - Fall Season
Lesson 3 Observe Green Down
Join GLOBE Grandma as she guides young learners in observing leaf color in the GLOBE Green Down investigation. Early primary students can do GLOBE, too! They are NASA's microexplorers through the GLOBE program!
Lesson 4 Check Your Leaves
Join GLOBE Grandma as she goes back out with her family to check on how their leaves are changing. Will the adopted leaves be still green, or have they changed colors? What other surprises do they find at the site, and what should Grandma do when she accidentally pulls a leaf off?!
Lesson 5 Why Do Leaves Change Colors?
GLOBE Grandma explores with her family why leaves change color in the fall with a demonstration using pigments. Just as leaves lose their green chlorophyll pigments, Grandma and Simone use a simple chromatography experiment to understand how colorful pigments can be hidden behind other colors. To learn more, they call plant ecologist Dr. Christa Mulder from the University of Alaska Fairbanks Institute of Arctic Biology.
This lesson is an early primary grade adaptation of the GLOBE learning activity "Investigating Leaf Pigments."
GLOBE Grandma - Winter Season
Lesson 1 We know about snow!
This first lesson in the Grandma GLOBE winter series gets children ready to learn about snow and how it changes through time or across different places. After watching the video, use the activity sheets to give the children the chance to observe snow, think of what they know and notice, and what they wonder about snow.
Lesson 2 Planning your snow site
Where would be a good spot for you to monitor snow in your yard, neighborhood or schoolyard? Join GLOBE Grandma in thinking about and mapping the best spot to make GLOBE snow depth measurements.
