We often think of trees as being dormant during the cold winter months. But like many of us who are preparing for warmer weather, trees are too.
Take a walk outside. Look closely at the tips of the tree’s branches. Have they started to set their leaf buds already?
Some tree species create buds in the late summer and fall to get a head start on next year’s growth. In addition, some flowering trees will have flower buds getting ready for their spring debut. Botanists, arborists AND YOU can use tree bark, branching patterns, and the shape and patterns of its buds to identify tree species in winter also.
This promise of the end of winter is a hopeful sign of new life to come.
Pair this knowledge with the fun book Crinkleroot’s Guide to Knowing the Trees by Jim Arnosky and head out on a winter adventure to peek at the trees!
Blog post from Kevin Anderson, DPI Science Consultant
"In this era of COVID-19, educators have faced immense challenges and responded with incredible resilience, and with innovative ideas to continue to support our students. A few weeks ago, I was asked to speak to some of these challenges—and some possible solutions—during a virtual event on STEM 101 for new members of Congress and their staff, hosted by the National Science Teaching Association and the STEM Education Coalition."

Harriet Tubman, an Unsung Naturalist, Used Owl Calls as a Signal on the Underground Railroad
This fascinating article highlights the incredible knowledge of the natural world that Harriet Tubman utilized in her journey to freedom and her leadership on the Underground Railroad.
"At the Harriet Tubman Underground Railroad State Park in Church Creek, Maryland, Ranger Angela Crenshaw calls Tubman “the ultimate outdoors woman.” She even used bird calls to help guide her charges, eventually helping some 70 people, including her parents and four brothers, escape slavery.
"We know that she used the call of an owl to alert refugees and her freedom seekers that it was OK, or not OK, to come out of hiding and continue their journey,” Crenshaw says. “It would have been the Barred Owl, or as it is sometimes called, a 'hoot-owl.' 'They make a sound that some people think sounds like ‘who cooks for you? Who cooks for you?’ ”
That nugget comes to Crenshaw from the park’s historian, Kate Clifford Larson, author of the Tubman biography Bound for the Promised Land. “If you used the sound of an owl, it would blend in with the normal sounds you would hear at night. It wouldn’t create any suspicion,” Crenshaw says.

Lightning on other Planets, Really?
This Saturday at 1pm, UWM CoffeeShop Astrophysics group will be livestreaming their first virtual CoffeeShop talk of the spring semester! This talk is titled "The Science of Lightning" and will go into how lightning forms and why, as well as the many different forms of lightning (blue jets, elves, sprites - those are actual names), and lightning on other planets.
The talk will be pre-recorded and livestreamed on their YouTube channel. This particular talk will also be split into a number of shorter "episodes" which will be released over the next week (the first episode being Saturday).

Winter Activity Kits
The SDW EE team has created several winter activity kits that are free to reserve and use with your students. Simply fill out this reservation form and someone will be in touch with you regarding delivery. You can request kits through this form.
Grades K-3: Shelter Building Kits: collection of small natural materials such as sticks, bark, and rocks that can be used to create a shelter for a small toy figurine. Can be done inside or outside. Full instructions
Grades 2-12: Sosemanuk (Snow Snake): a team challenge based on a winter sport played by many eastern Canadian and Wisconsin indigenous peoples. The object of the game is to slide the "snake" (cross country ski, referred to as a meter stick in the instructions) further than your opponents. Full instructions
Grades 4-12: Team Challenge - Lake Michigan Waterline: This is a large group problem solving challenge. The goal is to move the “water” (jingle bell) through the “waterline” (various pieces of plastic pipe), without touching the water with the hands, fingers, or any other body parts. Full instructions
