9: Earth’s Dimensions
For each group of
three of students:
3 Student Activity Sheets for Learning Experience 9 (Please see PDF
6 copies of the card modeling pattern for the 10 x 10 x 10
cm cube (Please see PDF
6 #16 rubberbands
For the class:
4 cereal boxes
Read the background information in the Rocks, Minerals, and
Landforms Teacher’s Manual. (Please see PDF
boxes are required for this learning experience. You will need students to
collect four regular cereal boxes for each model that is constructed. Students
should construct at least one model for each group. A model for each student
would require that additional boxes be collected. Patterns are provided in the
teacher’s manual that will need to be copied for the students. Patterns are the
full-scale drawings provided to make cardboard templates. Panels are the result
of tracing the templates on another cardboard surface, marking the locations of
the connecting scoring/folding lines and the locations, for hole punching.
will develop models of the relationships between the surface area and volume of
the Earth’s lithosphere, hydrosphere and atmosphere.
How do the earth’s
lithosphere, hydrosphere, and atmosphere compare?
Introduce the term lithosphere, hydrosphere, and atmosphere
to the students. Explain that they will be building models that represent parts
of the earth and then will compare various features of the models. Ask the question,
“Have you ever seen a globe model of the earth”? “What information could you understand
from the model”? Direct the students to carefully disassemble the cereal boxes while saving the largest cardboard panels.
Six panels will be needed that measure about 13 cm x 13cm square. Students
should follow the instructions on the activity sheet for Learning Experience 9
in the Rocks and Minerals and Landforms Student Activity Book.
What new understandings did the model help you with?
How does the volume of water on the earth compare with the
surface area of the water on earth?
Additional copies of the 10x10 cm grid paper found on page
47 of the Teacher’s Manual (Please see PDF
) may need to
be made if each panel is covered with the grid.
