For the third consecutive year, the Ain Aar Grade 4 students led by their teacher Anne Bechara have had the pleasure to participate in the 20/20 Challenge under the theme of Biodiversity and specifically Ecosystem Losses. Our students partnered up with two schools in the United States, Rye Country Day School in New York and Edward W. Morley School in Connecticut. The collaboration on this project took place over the months of April and May. Using their PYP transdisciplinaryskills, the students researched, formulated inquiries, acquired knowledge and presented their findings using a variety of mediums such as posters, PowerPoints, skits and poems. This challenge helped give the students an incentive to become citizens of the world, knowledgeable and proactive towards any problem that might arise.
