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!

Lesson 3 Measure snow depth


Join GLOBE Grandma as she guides children in this early primary grades adaptation of the GLOBE total snowpack monitoring protocol. The snowpack data collected can help scientists using GLOBE data understand how much water is on the landscape in the form of snow.

Submit snow data from your sites to GLOBE Alaska


Lesson 4 Observe changes in snow depth


Join GLOBE Grandma as she revisits her GLOBE snow site and sees that big changes have occurred! Observing changes in snow depth helps children observe and understand changes through time, and the data collected can help scientists using GLOBE data understand how the timing and amount of snow is changing.

Submit snow data from each time you check your site to GLOBE Alaska


Lesson 5 Comparing snow in different places


Join GLOBE Grandma and her early primary aged grandchildren discover the differences in snow depth on the river and on the land using GLOBE protocols. They call on University of Alaska snow and ice scientist Dr. Chris Arp to discuss their results. Join in the fun and try it yourself using the activity sheets below.
