The
Sun's Daily Cycle
|
|
Overview:
Students
observe a slideshow of the Earth from space. They notice patterns in how
sunlight hits the Earth over the course of a day — and try to make
sense of the changes they see.
Teaching
Ideas
- The first
time students run through the slide
show, have them click through fairly quickly to create an animation.
Ask, What patterns did you notice? What questions do you have?
- Next,
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 handout, below, can help you guide the class discussion.)
Digging
Deeper
Consider
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 sheet below. (The teacher version includes answers.) If you have older
students, pass out copies of the student version and have them work on
their own.
