These model lessons were created by teachers participating in the Minnesota Department of Education's 2011-13 project, "Integrating Environmental and Outdoor Education into Grades 7-12" with funding from the Minnesota Environment and Natural Resources Trust Fund as recommended by the Legislative-Citizen Commission on Minnesota Resources.
Title of lesson: Wetland Investigation
Content area: Science
Grade level: 5
Learning objective: Students will know the parts of a wetland and how they work together to filter water.
Standard or benchmark addressed:
Science 188.8.131.52.1, 184.108.40.206.1
Description of lesson and how it is adapted for EOE:
1. Students visit a pond and a wetland near the school. Students write down all living and non-living elements they see.
2. Students predict the niche of each element of the wetland they noted.
3. Students read the information on Wetlands and take notes on why they are important.
4. Students read the Magic School Bus on Water Sanitation.
5. Students compare the parts of a wetland to the parts of a water cleaning station.
6. Students build a model to replicate each part of a wetland in a clear plastic tub.
7. Students note how their wetland model will clean water.
8. Students place an eye dropper in their wetland against the plastic.
9. Students add one teaspoon of red food coloring and observe what happens immediately, after five minutes, after thirty minutes and after twenty four hours.
10. Students compare how their model cleaned the dye to how water is cleaned in a wetland.
Teacher's role (i.e. specific activities and instructional strategies):
Lead students to wetland or wetland, point out points of interest in the area.
Ask leading questions which make students think about the parts of a wetland and how they help one another.
Check that students have documented the living and non-living parts of a wetland.
Wetland Field Investigation
Hand out the MN Wetland packet, chapter 3 Minnesota Waters-Wetlands and Groundwater. Instruct students to read it as a group, to note the main ideas and supporting details of each section with a heading.
Discuss the different parts and importance of a wetland with the class when everyone has completed their notes.
Read Magic School bus to the class.
Compare the similarities and differences between wetland areas and water purification center.
Wetland Model Investigation
Have all bins, eye droppers and any wetland materials you are providing organized for students. (You may want to provide sand, peat moss, plant matter, and water for students. I have students bring in their own materials but have options for them to use if they forgot.)
Review the parts of a wetland and what role they play.
Instruct students to fill in the wetland worksheet. Make sure they note how their model replicates the wetland.
Other resources needed:
MN DNR Wetlands Chapter 3
Magic School Bus Water Purification
Clear Plastic Bin for each group
Red Food Coloring
Eye dropper per group with the top removed
How students are assessed:
Students compare how their model wetlands work to how actual wetlands work.
One period for wetland tour
One period for reading materials
One period to build and observe the wetland. Students may finish readings while doing observations.
