My First Three Weeks Back.

My First Three Weeks Back.

Week 1:

In week one of term Three 7Ld learned that we were doing science this term; Yay! Our teacher is Mr Palmer, and we have science on a Monday and Thursday. We also found out we were getting a new student called Jhermaine. 

Week 2

In Week two 7Ld learned that next week the year 7&8s were going to Orana Wildlife Park on Monday for the day and we were getting another new student called Wajihah who was coming from Fiji 

Week 3

Like I said in week three the year 7&8s  whet to Orana Wildlife Park for the day. We were split into groups and went to see the animals and my group first saw the reptiles. I really liked the lizards because they blend in with there surroundings and where the hardiest to find, but my all time favourite animal has to be the kiwi because its a native animal and they are really cute. Last time I was there I saw the meerkat and porcupines and those where really amazing. I love the meerkat because the first time I saw them was with my grandma for a treat. 

All in all this three weeks have been a blast so much fun. my favourite week has to be... Week 3 

Here is some photos of the animals 

Hands down the best first three weeks back ever
