Fourth class have been busy working on this strand recently. They initially studied the strand unit of Sound.
They made their own string telephones and discovered that sound travels better and faster through a solid material than through the air.
They also covered the strand unit Forces. They made some wonderful balloon rockets and discovered how the balloon flies across the string because of air and thrust . They also designed and made some paper helicopters and through investigation they came to appreciate that gravity is a force .
Senior Infants studied the strand unit of Force this month also. They designed and made some incredible catapults. They then experimented with the force applied and the weight of objects shot.
