Trip to the Science Centre

Yesterday,all the classes of Primary 4 went to the Science Centre,including me.It was very fun and interesting because there were many fun things,such as the DNA part.First, we went to a lecture room.We learnt about how ultraviolet rays work,help and where do they come from.The lecture room was filled with many things which were related to Science.Mr Yeong,the Science lecturer,talked to us about "light",the chapter which ma'am is teaching us now.I liked the chapter"light" because it tells us about rays and many things.Mr Yeong also told us about the "infra-red",how does light travel and in what way can light help us,the human beings and plants.An infra-red is a source of light that cannot be seen humans.Second,Mr Yeong lead us to the "animal life"part.There were small chicks popping out from their shells.They were all very cute!I hoped that I could bring them back to my house and raise them up.Next,something made me ran vigorously.Eek!They were the cockroaches!Some of them were moulting,which means that they were "tearing"their old skin!I walked to the mealworms which were in a container.One of them was casing an egg case.Third,some of my classmates and I walked to the "frog's croaking machine".I made a frog croak and recorded it.Ma'am called us and we went back to our school.Wee!
