This term we are studying the Earth. We study the seven continents (Asia, America, Africa, Antarctica, Europe and Oceania), the five oceans (Pacific, Atlantic, Indian, Arctic and Artarctic), the water cycle (evaporation, precipitation, condensation and collection) and the atmosphere (air, oxygen and protection).
Here is a video with a song about the continents, but they say Australia instead of Oceania.
Here is a video animation about the water cycle. It is funny.
