Botanic Garden of the University of Coimbra = Scientists pupils in the Garden-ECOMATA = Guideline to develop the lesson materials (Composed by four sections, which can be printed and used separately) 1. LESSON OVERVIEW Scientists pupils in the Garden-ECOMATA Title Programmer Curriculum content / Grade Level/ Target Audience Anticipated time Abstract Competences Kind of activity Prior learning Ana Cristina Tavares Ecomata: estudo de um ecossistema terrestre. O/El Botânico, 6:40-43 (2012). http://www.elbotanico.org/revista6.html Ecosystems, biodiversity and sustainability on Earth - current curricular programs: th th th rd th rd Science (7 , 8 and 9 of the 3 basic level) and Geography (the 9 of the 3 basic th th level)/7 to 9 Portuguese grade (ages 12-14)/ School students. 2.5-3hours. With a guiding-questionnaire pamphlet - ECOMATA - and the teacher assistance, the plants are used as models -evidences- for student’s interaction with the garden, to understand the influence of the abiotic factors, the intra-specific and inter-specific relations of the living beings and how the Ecosystem components are related. In the Arboretum, splitting in two team work and to realize “how scientists work”, using the scientific method, the pupils cooperate and study a terrestrial Ecosystem, collecting data and assess two selected sampling areas using the squares’ method. After, they perform laboratory experiences and analysis, data sharing, interpretation and discussion for plenary presentation, discussion and conclusions. They reflect on the importance of climatic changes effects (non-biotic factors) and biotic factors in biodiversity and the relations of the living systems. Contacting with an experimental design, students realised what and how to study in the ecosystems dynamics over time, finally understanding and concluding on the importance of biodiversity and sustainability for Life on Earth. With a scientific design, a case-study of biodiversity, ecosystems and the effect of climatic and seasonal change. 1. Using a botanic garden to understand the concept of ecology, ecosystems, biotic, non-biotic factors and their interactions; 2. Learning what is and how to use the scientific method applying it in an ecosystem case-study; 3. To understand the importance and differences of climate and seasonal changes in biodiversity and how Humankind is part and factor (agent) of the Global Ecosystem. A practical co-operative learning in the garden, laboratory and classroom; observing and assessing the ecosystems and biodiversity in the garden; organizing, sharing and comparing data; interpreting and discussing results; reflection and concluding on new knowledge; formulating question-problem situations for further studies. Not required that students have previously seen the botanic garden collections and spaces. Botanic Garden of the University of Coimbra = Scientists pupils in the Garden-ECOMATA = STUDENT ACTIVITIES 2. STUDENT ACTIVITIES A context: with a garden guiding-questionnaire pamphlet, interacting with plants trough the garden, some initial questions: Do you know what a botanic garden is? And about an ecosystem? Is a tree part of an ecosystem or is it itself an ecosystem? What factors can influence biodiversity and an ecosystem? After, e.g.: Can you point to: individual, population, community, ecosystem, in the garden? What are the differences? Can we control the climate changes or the causes for extinction? What role do plants play on Earth and how do they relate with other living beings? Do you know an example of “plants that are predators”?!! Why does it happen? Are the plants in a bamboo plantation an example of intraspecific competition? Is there any cooperation between plants? Why? … After this approach with living models in the garden, go to the Arboretum, and split in two teams and “be a scientist”: Observe the two samples of terrestrial ecosystem; assess the selected sampling areas using the squares’ method, materials and the worksheets and helped by teacher. Finishing the outside work, as “scientistpupils”, go to the laboratory, making experiences, analysis, sharing data with colleagues. In a plenary, comparing and discussing the collected data, present your interpretation, reflecting and concluding with colleagues and the teacher, on your ecosystems study and importance. Student materials, tasks and worksheets: Task 1-objective. With a guiding-questionnaire in the garden, interacting with plants and helped by teacher, to understand on ecology and ecosystems; task 2-introduction.

Duration: 2.5-3hours. Curriculum links/Grade level and students’ age/ Background information/Prior learning th th th Ecosystems, biodiversity and sustainability on Earth - current curricular programs: Science (7 , 8 and 9 rd th rd th th of the 3 basic level) and Geography (the 9 of the 3 basic level)/7 to 9 Portuguese grade (ages 12-14)/ A previous approach to the garden/ An introduction to the theme of the activity is given to the students that are expected to have had a previous contact to the garden collections, interpretation and spaces. Two Arboretum different samples areas should have been previously marked and studied by teacher to be used by students as “ecosystems case-studies”. A previous preparation about the Botanic Garden collections by teacher/educator is applicable. Summary This lesson is about the influence of the abiotic factors on biodiversity and to understand the intra-specific and inter-specific relations between the living beings and how all these Ecosystem components can be studied, how they are related, so affecting biodiversity and climatic changes on Earth. Interpreting the garden’s live models, multiple concepts are explained and exemplified as evidences. Biotic and abiotic factors, intra-specific and inter-specific between living beings, identification of plants, and all these concepts are assimilated by students using “hands-on” and “minds-on” practical exercises. In the Arboretum, as a second part of the lesson, applying the method of square areas and using the worksheets, the dichotomous keys and other exercises, materials and resources, the students are organized in two team work, complete data collection of the samples to complete studying at laboratory with experiences. Then, data is analyzed and shared and will be interpreted and discussed. In a plenary, the two groups preform the data presentation, discussion and reflexion, catalyzed and helped by teacher. The main IBSE question is to recognize this method as an experimental methodology for monitoring climate and seasonal change and its effects on biodiversity and ecosystems, either in a local or global scale, and understanding their importance for the sustainability of Life on Earth. Learning outcomes and competences Knowledge: to identify and understanding biodiversity, climate and seasonal changes, ecology and ecosystems concepts using an outdoors context; constructing knowledge about the ecosystems elements and links, the sample areas and their ecological characterization; to move forward their learning identifying the biotic and abiotic factors and their interactions, and evaluate the effects of climatic changes on biodiversity, seasonally and over time; to learn that there is a range of biodiversity in different areas and perform experimental designs to study; linking to everyday life situations, concluding why the three ecologic factors (biotic, abiotic and interactions) the Life on Earth, as a global ecosystem; students relate this knowledge to real life scenarios and human values, attitudes and behavior. Skills: to arouse curiosity about “how scientists work” and nature can be interpreted and studied; provoking the interest on biodiversity, ecosystems, ecological studies and sustainability; development of the observation, creativity and exploration abilities and tools to achieve the proposed goal, constructing and responding to a scientific design; use prior scientific knowledge, to undertake a problem solving activity and communication in small and large groups, sharing hypothesis with the class, negotiating a consensus statement; exploring and comparing biodiversity and climate or seasonal changes of ecosystems; to understand its value and to behave accordingly. Social Learning: to share work and opinions in a team; to stimulate discussion and the capacity for decisions and choices; to understand the importance of natural sciences and of the scientific work. To become conscious of the reality of Life on Earth, how it works and can be study and how each species and element takes part and affects the Global Ecosystems, its Biodiversity and Climatic Changes. So being each of us responsible and having the right and the duty to contribute for a better quality of Life on Earth and to behave accordingly. Lesson Outline Introducing: The vast living patrimonial offered by the Botanic Garden of Coimbra inspired the willingness to teach. Using a diversity of resources it is possible to promote experimental teaching and to develop the interest for scientific learning and implementing the ECOMATA. This activity, based on the program contents on th th th Ecosystems, biodiversity and sustainability on Earth - current curricular programs: Science (7 , 8 and 9 rd th rd of the 3 basic level) and Geography (the 9 of the 3 basic level), consisted in the realization of an ecological circuit. Teachers and students are invited to act in a practical, interactive and inquisitive way, applying the knowledge already acquired in the classroom or being for the first time introduced to this subject in the garden. With a garden guiding-questionnaire pamphlet (form), direct contact with garden plants allows students to understand and test the concepts learned and explore new arguments. Based on the form, it is the student who builds and applies knowledge, with enhanced monitoring and motivation on the part of the teacher, following the methodology inquiry based educative learning. The aims of the lesson are the study of biodiversity, ecosystems and the effect of climatic or seasonal changes with the use of a scientific method. List of activities: After a prior approach on the living collections and spaces of the Botanic Garden, make an introduction to the theme of the activity. Then, it will make more sense for the pupils about the visit to the garden and they will have more motivation to gain new knowledge. Delivering them a guiding-questionnaire pamphlet, do inform pupils that it is not to assess them, but to help, motivate and assist both students and teachers for the practical study of ecosystems. With the definition of the space of the Botanic Garden, it was pointed out its scientific, educative, cultural and social importance. IBSE is about taking students on a journey. The teacher has the role of facilitator that helps students to scaffold their learning. This can be done by setting challenges and providing students with helpful questions. Using the form and setting a challenge to the students, plants of the BG are used as living models to introduce the main notions in Ecology. A teaching trial guide in the garden, presenting the main stop and points for interpretation is further described with the objectives, strategies, concepts and the botanical models to explore, such as: Next to the Tilia x vulgaris the question is: is a tree part of an ecosystem or is it itself an ecosystem? The question allowed the exploration of concepts such as: individual, population, community, ecosystem, among others. Next, we find the oldest plant of the BG, Erythrina crista-galli, which allowed us to point out the influence of the abiotic factors, considered as an individual and as an ecosystem, being also possible to observe the existence of the relations of symbiosis, commensalism and competition. The cooperation between individuals of different species was exemplified by the relation between the sparrows that use the seeds of the fruits of the Liquidambar styraciflua. Near the Ficus macrophylla, the visitors were able to confirm the relation of competition between this plant and its neighbours, the palm-trees. The pupils were questioned about the existence or not of “plants predators”. Someone answered: “Yes, the carnivorous plants!”, as it was confirmed by observing the Dionaea muscipula. In the Arboretum, observed the Quercus cerris, victim of a pathogenic fungus (parasitism), and The bamboo plantation (Phyllostachys bambusoides), as an example of intraspecific competition. Is there cooperation between plants? We concluded that each plant is self-sufficient, not depending on the others for its survival. After the initial approach, the pupils go to the Arboretum, to study two samples of terrestrial ecosystem, assess two selected sampling areas and using the squares’ method. The circuit is finished and then followed by laboratory experiences, analysis and discussion of the collected data, to present in a plenary. Completing the formative action as “scientist-pupils” it is enhanced that any scientific study must be much more comprising, demanding the repetition of procedures, seasonal monitoring and laboratorial experimentation over time. In addition, it should be emphasized that this experimental study can be replicated and be applied to any other green area (inside or outside school), so being a sustainable experience itself! The Ecomata thus constitutes a model for all schools and green areas, allowing the sustainability of projects of this nature. Key processes: co-operative learning in the classroom and in the garden; observing and measuring the ecosystems and biodiversity in the garden, finding the sample area and apply the squares’ method, comparing and organizing collected data, discussing and interpreting the obtained results, modeling and formulating problem situations for further studies elsewhere. Plenary: The groups present and discuss their samples in a plenary, using the data, explaining the casestudies, the work design and the achieved conclusion. They can reply the other group, catalyzed by the teacher/educator. Students debate, reflect and conclude about: How about the results of the two ecosystems-samples study? What differences did you find? Can you propose an explanation for his? How can biodiversity in an ecosystem be defined and studied? How can biodiversity and ecosystems be affected and which are the main factors? Next time/years, will they find the same biodiversity in the same samples of the garden? Why?? How can this be monitored and studied? What is the difference and importance of seasonal and climatic changes? Are plants sustainable systems? And you? What is our part on the global ecosystem-the Earth? How do scientists work? Did you feel like a scientist? Why? What do you do for sustainability on Earth? Can you suggest any future work? And any future world scenarios on biodiversity and climate changes? ….. Assessment Assessment centered on competences, related to the learning outcomes.

Botanic Garden of the University of Coimbra = ECOMATA-Scientists pupils in the Garden= TEACHING TRIAL GUIDE (OBJECTIVES, STRATEGIES, CONCEPTS AND BOTANIC MODELS TO EXPLORE) 1st Stop – North Gate Objectives/clues/cues: Welcoming visitors; why did they come to the garden? What is a Botanic Garden? a place where we can find collections of live plants from across the world generally for scientific studies. can be general (like Coimbra) or specialized (Barcelona - Mediterranean Flora). Key functions? Education, research, conservation and recreation. Tell a brief history of the Botanical Garden of Coimbra Created initially for scientific studies in medicine and pharmacy Founded by the Marquis of Pombal in 1772 (about 20 years after the great earthquake of Lisbon) has 13 hectares (13 football fields), including 4 of formal garden and 9 of woods (arboretum). Propose to fulfill the helping garden guiding-questionnaire pamphlet (=form), only when requested How important is this subject? Concepts: Ecology - science that studies relationships between living beings and between them and their environment. Gr. oikos (home) + Logos (study); triangle (biotic / abiotic factors / interrelationships). Biosphere - Set of all living beings on the planet Earth and the space that they occupy, which by interacting with the physical environment, constitute a whole. Includes part of the atmosphere, hydrosphere and a part of the lithosphere (pedosphere - soil); Gr. Bios (life) + Sphaira (sphere). 2nd Stop – Cedar (Cedrus deodora) Objectives: Levels of organization: cell / living being (species); species / ecosystem. Compare with metric system (species - basic unit / meter – basic unit) Start filling the form - first table. 3rd Stop – Linden tree (Tiliaxvulgaris) Objectives: How important is to know the parts and the whole? refer to the story of the 3 blind men touching an elephant Concepts: Organism (Linden) - Entity able to keep alive their organization, with unique characteristics, transmissible to offspring; Population (Mall of Lindens) - A set of organisms of the same species occupying a given area at the same time. Biotic community / biocenosis (set of living beings in the Botanical Garden) - Set of populations occupying a given area. Greek: Bios (life) + koinos (common) Ecosystem (set of living beings Botanical Garden + abiotic factors + interrelationships) - Set of all living things in a particular area, their relationships and interactions and abiotic factors. Triangle – metaphor for ecosystem. Gr. oikos (home) + topos (place)Abiotic factors (light, temperature, soil, moisture) - Set of physic-chemical factors; Soil - superficial layer of the earth's crust resulting from the weathering of rocks and organic matter decomposition. Biotope (total area of the Botanical Garden) - Area of variable length with favorable adaptation of a group of living beings. Gr. Bios (life) + Logos (study) Habitat (Garden terraces, forest, etc) - Local, environment or physical space occupied by an organism. Linden tree: individual or ecosystem? application of concepts / identification of organisms present. 4th Stop – Central Square – Erythrina crista-galli Explore the label: Leguminosae? - label = Identity Card; species characteristics. Apply concepts - inter-specific interactions: Mutualism (Lichens), Commensalism (mosses, ferns and Crassulaceae), Competition (by space, light) Importance of abiotic factors: abnormal shape of the tree; (anatomy) Transversally of knowledge; function / shape; distribution of ferns and mosses (need higher humidity and lower temperature for its development) vs. crassulaceae (exists in sunniest areas); (major plant groups) Concepts: Biotic Factors - set of living beings interacting. Species - a group of organisms that share characteristics with each other physiological, morphological, biochemical, behavioral and sharing the same genetic background, which can interbreed resulting in fertile offspring. Intra-specific - between organisms of the same species. Inter-specific relationships - between organisms of different species. Mutualism / Symbiosis (lichens) - Mandatory Association in which a species can not survive without the other and vice versa, benefiting both the association. All symbiosis is mutualistic, but not mutualism all is symbiosis. Commensalism (mosses, ferns and crassulacean on Leguminosae) - optionally opportunistic relationship where only one species benefits without however adversely affect each other. Competition (crassulacean vs ferns and mosses) relationship between organisms fighting for the same goal. In extreme cases can lead to the death of one of them. 5th Stop – Central Square – Liquidambar styraciflua Concepts: Cooperation (Liquidambar vs. Bird) – Facultative mutual help established between organisms in which both benefit. Liquidambar. - Cooperation with certain group of birds (fruit morphology only allows entry of a particular type of beard’s beak, however, the plant doesn’t depend on bird for seed dispersal, nor the bird feeds only on these seeds). 6th Stop – Ficus macrophylla Commensalism, Parasitism, Competition, not static inter-specific interactions; Living systems are dynamic systems; action of environment, evolution by natural selection. Currently competing for space with palm trees. What is expected for the future? 7th Stop – Arboretum gate Establish differences between the Garden (garden "organized") and the Arboretum (garden "disorganized"). Human intervention. Botanic gardens are usually “made by man” and the garden plants have been planted in the areas and do not occur naturally, being subjected to more or less man interference. 8th Stop - Bamboos Example of Intra-specific cooperation in plants? - Plants self-sufficient not dependent on other organisms for their survival, without the need to live in society. - Animals dependent on the plant world (directly or indirectly) - importance of preservation; different trophic levels. autotrophy / heterotrophy - Do animals depend more on plants or plants on animals? Analysis of examples as evidences. Intraspecific competition for space and light. Panda is totally dependent on bamboo - herbivory. Are there are more species of plants in the world or more species of animals? Are there are more plants or animals in the world? Which have greater biomass? Use of dichotomous keys (ficus / bamboo); stem / leaf Review of the concepts discussed in conjunction with completion of the form. Metaphor of the house (house - ecosystem; examples of existing populations and interactions). Introduction to what will take place - How to study an ecosystem, chosen method, the scientific method (observation, experimentation) Mention: The study of an ecosystem implies non-alteration or destruction; appeal to silence. Arrange groups. 9th e 10th Stops – Square 1 / Square 2 Overall assessment of the Arboretum Study of sampling areas following items in the form. Quadrat (squares) method. Within the square itself recognize the presence of the concepts discussed before Emphasize the study of animal community as something much broader than done (mobility, migration, hibernation ...). Concepts: Soil pH - resulting from its chemical composition. Certain plants live in soils of very specific pH, in agriculture; soil pH is often corrected in accordance with agricultural needs. Mostly is between 4 and 8.5. E.g. Hydrangea flowers - pink and blue in alkaline pH in acidic pH. 11th stop – Arboretum exit • Brief review of issues discussed, clarifying doubts. • Scientific method: more sampling areas, repeat procedures, importance of monitoring seasonally (annual species, such as clover), further laboratory experimentation. th 12 Stop – greenhouses – carnivorous plants Concepts: Predation – Relationship between individuals where one feeds on the other, always leading to its death. Carnivorous plants Predation, inter-specific relationship with the insect; case of facultative predation that occurs in these plants under natural selection, as adaptation to poor soils. If plants are autotrophic, why do they have traps for insects? Are they flowering plants? If they live in a nutrient-rich soil in the greenhouses of the Botanical Garden, why do they produce traps for insects? … …… Botanic Garden of the University of Coimbra = Scientists pupils in the Garden-ECOMATA = Feedback questionnaire Please complete the sentences below: 1.
