This is a guide for your ecosystem study work. You can also find the file for download in the Materials -> Files -> Workhseets section of the twinspace, in a a variety of formats.
You can also download it here in .odt format
Part 1: General Description
1.- Ecosystem type (terrestrial, aquatic, salty water, fresh water)
2.- Position. Locate it:
- On an local map
- In relation to the school (distance)
- In aerial photos
3.- Production of a Ecosystem approximate map, showing
- Remarkable structures, both natural and artificial such as: rock formation, mountains and buildings nearby, forests or tree groups.
- Human action: positive and negative
- Approximate area
4.- Take pictures of the area to study. Try to show pollution remains and state of conservation, human action…
Part 2: Analysis of Abiotic factors
1.- Production of a climograph of the area to study.
2.- Data taking (atmospheric conditions):
- Air, ground and water temperature (in case of aquatic medium)
- Clouds: Type and cover, wind: speed and direction, environmental humidity
3. Identification and description of the analyzed rocks. Pictures for the blog
4.-Study of the ground:
- Terrestrial ecosystem:
“In situ” study of the ground and its features with magnifying glasses to identify the size of its particles (gravel, sand, clay....)
Afterwards, classification of the organic and inorganic components in the lab by using binocular magnifying glasses
- Marine or lake/river ecosystem;
Study and description of its particles (sand, stilt).
Classification in the lab according to size shape and colour together with their origin (organic and inorganic)
- Production of a granulometry of the samples in the lab
Part 3: Study of Biotic factors
- Moss, ferns and lichens:
Look for them and show their position on the map, pointing out their orientation and cover. Description and afterwards classification in the lab.
Search for information, in the classroom, about the lichens, as a bio indicator
- Herbaceus plants:
- Tree specimens:
- Algae (in aquatic ecosystems):
Describe 2 of each type (green, brown or red).
Prepare an ecosystem profile and point out their position.
Take photos and samples (if possible), to later classify them in the lab
Produce a small algae guide
Look for 2 specimens in each group, take photos and videos showing their movements
Anatomic description of each one
Sort out samples (shells)
Identify and look for traces (using simple guides)
Production of info cards: Usual and scientific name, features, way of living
**Watch out! Neither hurt the specimen nor damage its habitat.
- Fungi :
Samples picking up, description and photo taking.
Classification in the lab.
Search information about the role of fungi in the ecosystems and the use of fungi in the food industry, human diet...
Part 4: Relationship and adjustment to the habitat
- Production of trophic chains with the found living creatures and creation of a possible food web with them.
- Find information about inter specific relationships such as mutual, symbiosis, parasitism.....you can find in your ecosystem. Description of them.
- Look for examples of adjustment to the habitat among the studied species, such as humidity, saltiness, wind...
Part 5: Invasive species
- Research about the presence of invasive species in the area, and look for information about the potential consequences of their presence together with the existence of eradication programmes
- Try to find, at least, two examples of those species, describe them, and tell about their origin and their possible effects in the ecosystem.
Part 6: Pollution and Changes study
- Waste collection during visit and afterwards classification at school
- Plastic: Pick up samples and classification in the lab. Research about the effects of the plastic in the aquatic ecosystems.
-Picture collecting of the area in the last decades, to produce a small work about its evolution. Critical analysis and approach of the possible corrective measures
