observe slideshows of the Earth from space. They notice patterns in how
sunlight hits the Earth over the course of a day and a year — and
try to make sense of the changes they see.
Time Is It?
- The first
time students run through either slide
show, (One Day or One Year), have them click through fairly quickly
to create an animation. Ask, What patterns did you notice? What
questions do you have?
have them click through more slowly. Pass out copies of the Observing
Change handout and have them record their observations and ideas.
- As a class,
discuss students' observations, explanations, and questions related
to the changes they observed. Explain that, throughout their Journey
North adventures, they'll have an opportunity to discover some of the
"whys" behind what they see. (The teacher versions of the
question handouts, below, can help you guide the class discussion.)
running through one of the slideshows again. This time, help students
make sense of what they're seeing. You can ask the class questions on
the following handouts. (The teacher versions include answers.) If you
have older students, pass out copies of the student versions and have
them work on their own.
