These short, cold days of winter many animals experience a process called hibernation. For example: squirrels, groundhogs, bats, turtles, snakes or bears.
Previously, they prepare a nest where they “sleep” for a long period of time. Some animals wake during hibernation to eat and relieve themselves, while others sleep through the entire winter.
STEM Challenge #10 engages pupils to:
“Design and build a nest for a hibernating bear”.
Building time: 40 minutes.
Pupils should consider some criteria and restrictions. For example: nests must have an entrance/exit or bears must be protected from the rain, snow and wind.
