This transdisciplinary project combines the contents we inquired from Social Study with English language. Students are going to do research on different festivals of their own country and two countries they are interested in and make up one country and its festival on their own! Students are guided to asking questions about where, what and how. They are also encouraged to collect information from Internet. At the same-time, they got to use their imagination and creativity to create the funniest festival in a funniest country. Through their inquiry, they start to understand that our world works in so many different ways and our cultures can be so diverse and so similar!
