Goop to geoforms
Purpose
This lesson will illustrate geographical terms in three dimensional form.
Objective
Participants will be able to:
- Use magic modeling goop and paint to create features of the geographic landscape.
- Explain the meaning of geographical terms.
Duration
2 to 3 days (excluding teacher preparation)
Materials
For magic geoforms:
Magic modeling goop (make ahead using recipe
below)
(5 tbs. salt and 2 cups water to I lb. cornstarch and 2 cups water yields
10 tennis ball sized balls of goop ... one ball will complete 2 geoforms ...
wrap, excess in plastic to keep up to a year).
Sturdy cardboard squares, 5' x 5' (1 per geoform)
Tongue depressors, one per geoform)
Hot glue gun and sticks
Tempera paint (assorted colors and brushes)
Tools for flattening and sculpturing (hands usually enough)
Procedures
Teacher prepares the following ahead:
- Make magic modeling goop at home
- Cut cardboard
- Glue tongue depressors to cardboard
- Gather rest of items on list for student use
Day 1
- Compile a list of geographic terms students are familiar with and have
previously discussed and/or illustrated.
- Students choose one term to make with goop.
- Students write their landform. definition on a 3' x 5' (copy from book,
or use class definition)
- Glue definition on back of cardboard.
Day 2
- Students paint the dry geoforms using small brushes.
- Students give mini presentations to class. Student creator explains the
term and definition with geoform. in full view of group. Students might
reinforce what they've learned by orally quizzing one another, after all
have shared.
Day 3
- Place the geoforms and cards around the classroom and send the students
on an adventure of discovery (let the students read and explore on their
own). Once the students have seen all the cards and geoforms, begin using
the display to reinforce student knowledge on a daily basis.
- On a rotating basis display 5 geoforms each day. Call on five students,
one at a time, to choose a geoform, identify and describe it. Then check
for accuracy on back. Eventually, students might try to identify and explain
geoforms without the use of cards. They might also try to apply as many
of the five themes of geography to a term as possible.
Directions to Make Goop
- Mix and heat on medium,
5 lbs salt
2 cups of water.
- Mix in separate bowl,
1 lb. cornstarch
2 cups water
- Stir until smooth.
- Add cornstarch mixture slowly to salt mixture, stirring constantly
while still on stove.
- When the two mixtures are thoroughly combined, remove from
heat, roll into tennis sized balls and wrap in plastic wrap. Will keep indefinitely.
- Makes 16 - 18 balls of Goop.
