Summary
Students continue to learn collecting etiquette as they begin a Class
Herbarium. They examine 5 habitat areas to discover a particular areas
characteristics affecting plant growth, and they identify the areas
dominant plants. They look at literature with themes related to plants
and/or the region.
If
appropriate, you may wish to invite Elders and/or local experts
into the class or on the outside field trips for these activities.
Please see ELDERS AND EXPERTS in the Introduction for
guidance and adjust your timeline, accordingly.
Please review the information in NOTES on COLLECTING, PRESSING
and the CLASS HERBARIUM before beginning this section. Materials
suppliers are listed in the Resources section of the Appendix.
Activities in this section involve collecting plant materials during
the flowering season, although some seed activities are included.
Select 5 outdoor locations for the class to visit. Suggestions are:
beach, bog, meadow, sheltered valley, and exposed mountain.
Most of the activities in this section require time outdoors. If
the weather does not permit these outdoor activities at this time,
consider spreading the activities throughout other days. Alternately,
you may wish to focus on the literature activity and reading time,
and advance to Section Three, Activities 3, 5 and 6 before returning
to this section.

Activities
WHAT
DO STUDENTS KNOW ALREADY ABOUT PLANTS? (continued)
|
ACTIVITY ONE. Students read about plants in literature, beginning with
The Legend of the Bluebonnet or similar plant story. They locate
a story or book about plant use through research in the library, on the
Internet, by interviews, or with teacher-provided list. (see Readings
About Plants list in Resources section
in the Appendix). Students read the story or book and retell it in oral
reports or written reports.
Inside activity
Estimated duration: 20-30 minutes to begin, followed by reading sessions
in class or as homework.
ACTIVITY TWO. Students review collecting strategy and etiquette
Inside activity
Estimated duration: 20-30 minutes
Include advice from Elders and local experts, if available. Look at NOTES
on COLLECTING, PRESSING . . . in the Introduction for additional
suggestions. Review values described in The
Right Way to Live as an Unanga{ (see Appendix). Make a class
record of collection guidelines on large paper that can remain displayed
in the classroom for the duration of the unit.
HABITAT
STUDY, SPECIMEN COLLECTING, AND CLASS HERBARIUM
|
ACTIVITY THREE A, B, and C. Students visit selected habitats and begin
collections for a Class Herbarium. Students complete A, B, and C at each
habitat location.
Outside activity
Estimated duration: one to 5, 80-90 minute sessions outside, plus travel
time.
Begin a Class Herbarium. For detailed descriptions of collecting, pressing,
and mounting specimens, please see NOTES on
COLLECTING, PRESSING and the Class Herbarium in the Introduction.
Materials suppliers are listed in the Resources section of the Appendix.
The Class Herbarium will be 2 collections of pressed plants with protective
covers. One set will be identified and named. A second set will be without
names so that it can be used in other activities including assessment.
Plan on taking an outdoor trip for the next one to 5 sessions to habitat
areas that contain flowering plants. Suggestions for habitat areas include:
beach, bog, meadow, sheltered valley, and exposed mountain. One or more
of these habitats can be visited again during the seed activities in Section
Three.
ACTIVITY THREE-A. Organize the class into teams by color: green, blue,
yellow, red, and white. Student teams go to one of the pre-selected
habitats with habitat frames see materials aboveand lay
the frame on the ground. Within the frame, students record the characteristics
of the habitat. They observe plants growing in the habitat and complete
a Habitat Record Sheet.
ACTIVITY THREE-B. Students collect and observe seeds using Seed
Test Cards. You may wish to limit this activity to one habitat location
or repeat it at all habitats.
ACTIVITY THREE-C. Students collect specimens whose flowers match the
color of their group name. Students may photograph the collection area
and the plant before collection and may wish also to photograph the
specimen later in the classroom. Students make preliminary field identifications
using the Plant Illustration Cards.
ACTIVITY FOUR. Students identify plant specimens and prepare them for
the Class Herbarium. They fill out identification tags and records on
the computer using field guides and information from Elders or other experts.
Arrange for one of the students or a helper to set up a template beforehand
on the computer with the required Plant Information Card data.
Inside activity
Estimated duration: 20-30 minutes per plant collected
ACTIVITY FIVE. Students press their specimens. Based on your available
materials, describe the appropriate pressing methods to your students.
Review NOTES on COLLECTING, PRESSING . .
. in the Introduction for guidelines.
Inside activity
Estimated duration: 10-15 minutes to set up per plant collected; 2 days
to 2 weeks for drying time.
ACTIVITY SIX. Students mount and laminate their pressed plants to begin
the herbarium collection. Students add final information about plants.
(These may be as late as 2 days to 2 weeks later, depending on pressing
technique.)
Inside activity
Estimated duration: 20-30 minutes per plant collected.
Assessment opportunity: Using completed Class Herbarium specimen
pages that do not have labels, student identifies one or more plants and
describes 4 facts about the plant.
Assessment rubric:
Students and teacher complete assessment rubrics.
