Consists of material regarding the ecological pyramids which is organized in 3 stages: scenario, inquiry, decision-making.
Stage 1: Scenario
It was approaching nightfall when the guard of the state library was doing his routine check on all the bookshelves before it was time for him to go home. Although he performed this routine check for almost 30 years, that night he noticed a closed trunk sitting on the lowest shelve of the library right where all the books about ecology were. He approached and opened it, and in there he found an old dusty book which was written in 1893. Today, this book is considered among scientists as a "treasure" because in it, the author - Theofrastos Diogenous, describes the ecosystem of the Mediterranean shrublands found in Cyprus.
In the final chapter of the book he mentions:
"According to the scientific data that i have studied, i believe that in the future, the natural environment of Cyprus will be very different. Rainfall will significantly decrease and water will be difficult to find. And when it does rain, the rainfall will be torrential and catastrophic. The temperature will increase and the climate most likely will change. All ecosystems will be different. It seems that the unknown organism "X" will be a threat for the future ecosystem of the Mediterranean shrublands.
Stage 2: Inquiry
Various questions were raised:
What is this unknown organism X that the scientist was referring to?
In what ways can this unknown organism x be a threat to the future ecosystems of Mediterranean shrublands?
Could it be that the environmental conditions we are experiencing today are the same conditions Theophrastus Diogenous predicted in 1893?
What role does mankind play in the issue being described above?
Stage 3 : Decision-making
Students’ task is to study the ecosystem of the Mediterranean shrublands as it is today and examine the changes that took place, in relation to the data that T.Diogenous provided in his published book in 1893. In order to complete your task, you are required to give factual answers on the above questions in order to solve the puzzle.Strong points and opportunities:• Utilizes "inquiry" as an educational methodology
• Activates the motives of students
• Raises the interest and participation of low-achieving students
• Utilizes structured work sheets and integrates technology with complimentary electronic material consisting of videos, animations, population models-simulations etc.
• Relates to the everyday life of students.
• Relates to current events of everyday life.
• Contains field work in order for students to collect actual (real) data.
• Contains the execution of an experiment.
• Contains play (game).
• No need of previous knowledge.
• Raises the self-confidence of students.
• Cooperative Learning.
• Uses population models.
• It's in accordance with the methodology and philosophy of Next Generation Science Standards (NSTA,2013).
• Students learn and apply scientific practices.
• Helps students to:
o Understand the nature of science
o Learn the appropriate scientific methods scientists use to figure out an ecological problem.
o Work as young scientists and experience first hand proper scientific practices.
o Promotes concern and awareness about the environment.Limitations:• Structured inquiry
The structured inquiry is considered that it has a level of weakness because it limits the degree of self-acting and ownership of students and teachers. However structured inquiry is considered the optimum educational approach if the teachers and students are not fully prepared to implement an open inquiry.
• Somewhat long duration (5 χ 80΄)Added value with regards to the 3 topics of the MASS project:• Activates the motives of students
• Raises the interest and participation of low achieving students
• Utilizes technology and can address digital learnersAny prerequisites needed:• No prerequisites needed. Only basic pre-knowledge
