BETWEEN US … ORGANISMS Activity for April/May 2019.

WORKSHOP 1
INTRODUCTION
Talking to students, explain the purpose of the activity. Think, based on our own experience, how many times we have been in a situation to intervene in the relationship between the prey and the predator trying to disable the predator in his intentions. Of course, we would save the prey, victim and conclude that we did a good deed. But is that so? Ask the question: What would happen if, for example, people would often release frogs from the copperhead's jaws or sparrow from the hawk's claws so that predators always kill each other? The students will conclude that this would lead to the appearance of a large number of frogs and sparrows and to the destruction of the copperheads and hawks. The consequence of such order of organisms in nature would disturb the number of other living beings that feed frogs and sparrows and ultimately lead to their extinction. In the end, food would disappear, and frogs and sparrows would disappear. And that would be the end of it. Explain the students how this kind of event is called an ecological catastrophe.

In this way, the students should become aware that this relationship between organisms implies interdependence in the diet creates the only possibility of preserving life on our planet. That is why this relationship is the most important. 7th graders will learn this school year about biolinbiology teaching systematics by studying their anatomy, physiology, ecology and evolution. Using the acquired knowledge, within the project "Mathematics-the queen of science", students will explore the nutritional relations between the parks of the Papuk Nature Park with a special emphasis on the Ivanjski rovaš type. It's group activity, workshop entitled: "I EAT, YOU EAT, HE EATS - RELATIONSHIP THAT KEEPS LIFE ON EARTH" (subtitle: "The nutritional realtion between Ivanjski rovaš and other organisms of the Park Papuk Nature Park"). After the presentation of a rare, strictly legally protected and the smallest lizard in Croatia, noticed 2008 only in the Papuk Nature Park and at several locations in Ilok, students will be divided into three groups.

Group 1: The production of food chains that include PP Papuk organisms grouped according to the diet in the producers and consumers of I, II, III and IV order and featuring Ivanjski rovaš as consumer II order.

Group 2: Production of nutrition grid (intertwined feeding chains - one member appears in multiple chains) based on analysis of the first group's work.

Group 3: Production of nutritional pyramids (number among members of individual nutrition groups) based on established relationships between organisms in food chains and nutritional grid after analysing works of 1st and 2nd groups.

Activity aim
To stimulate students' interest in science by researching nutritional habits of organisms, to develop students logical thinking and inference by placing individual organisms into appropriate food groups, to encourage environmental awareness among students to act
responsible and by respecting natural laws without harmful interference, provide the maintance of natural balance in the area where they live.
Motivation for activity comes from the fact that someone always eats something in nature and that is completely normal. By acquiring this natural legacy, it enables the circulation of matter and the flow of energy through the living being, which is the foundation of the entire life in the Earth. So, nutrition relations among organisms most clearly represent the dynamics of life that excludes any monotony.



Contemporary methods of work: collaborative learning, research work using ICT, dialogue method, writing methods, reading methods with understanding of teaching assignments, skillful drawing methods and color expression.
Learning Outcomes: Students will differentiate eating habits of particular species and their role in the food chain, assamble and explain nutrition chains, link feeding chains to nutritional grid and shape nutritional pyramid, monitor the abundance of organisms of specific habitat.
Activity Outcomes: Based on the established nutritional relations, the students conclude on the importance of conservation of all species, so that each of them contributes to a stable natural balance and the maintenance of the life we know it. Consequently, the students will conclude that they are involved in this process in their daily lives by taking the place of the highest order consumer - collectors, plowmen and hunters who have no natural enemies. Therefore, man carries the greatest responsibility.

The activity is created and accomplished by students and Biology teacher Brankica Safin.




WORKSHOP 2
Within another workshop called "Between Us ... organisms", students are examining examples of relations between living organisms.
They are conducting a research on the population of domestic animals that live in the same area as they do and based on collected data ,
they are doing statistical analysis and that way they link math to real life.



The students visited,on their own, several owners of pig farms, sheep, chickens, cattle. The owners held interviews based on which they collected the necessary information and photographed the farm and the animals. The owners of the farms are Josip Šomođi, Zdravko Vukovski, Željko Bobanić, Vjekoslav Hes, Goran Vuković, Dunković Dijana, and interviews were conducted by a student of the 6th grade, Josipa Dorić.
