a)      Tyres.

l       Tyres are made from rubber. Other rubber products include: erasers, mats, gloves etc.

T: Why do we need tyres? Why do drivers need to change new tyres?

l       We tried relating to kids feet. When they are wet after shower, kids tends to feel slippery on the floor.

Hiro: That’s why we must wear good shoes that have got good shoe tread. When shoes tread gets thinner or is finishing, it’s safer to replace them with new ones. Otherwise, it would be dangerous.

Jia Xun: Tyres allow the cars to be driven safely on the road.

l       Thus tyres with poor tread will be dangerous.

b)      Rubber.

l       Tyres price range differently depending on its sizes and brands. An average tyre causes RM300. Tyre is made from rubber which is tapped from rubber trees. Kids learnt that a rubber tapper leads a challenging life and we have to appreciate their hard work.

c)       Experiment: Tyres.

l       Kids assisted at assembling puzzle mat. 3 cups were prepared whereby 1 covered with plastic representing smooth tyre tread. The 2^nd. cup covered with plastic spread with butter representing smoother surface. The 3^rd cup covered with rough cardboard paper representing a new tyre tread.

l       Kids push the cups and cups that go furthest represents weak tyre treads. Most of the time, kids voted the 3^rd.cup as the best tyre tread.
