Rinneamar iniúchadh ar chonas a dhéantar fuaim. Bhí an-spórt againn ag cruthú go mbogann fuaimthonnta rís, ag déanamh fuaimthonnta in uisce agus ag cruthú gur is fearr a ghluaiseann fuaim trí leachtanna ná tríd an aer.
We studied sound this week and had great fun making soundwaves move rice, making soundwaves in water and proving that sound moves better through liquid than air.
