WALT write a information report about a resource found in the Canterbury area that is of significance to the Maori.
In Intergrated Learning we have been making models, posters and lots of other things. We worked in groups and had a animal we chose, in my case my partner and I did the Maui & Hectors dolphins. We chose these dolphins because it was an animals endemic to NZ, which was what we were focusing on. Every group had to complete a "Creative Plan" this was pretty much our plan on how we would make our model/poster etc and what we would need to make it. I am proud of what I have achieved doing this poster and am very happy with how it looked in the end.

Our Animal : The Dolphin
The Dolphin is an intelligent mammal. We are very lucky to have them. However, the number of dolphins in the whole world are dropping rapidly. Believe it or not, Killer Whales are a type of dolphin. Since the Killer Whale is such a big animal, it's easier for them to get stranded, caught in nets and killed. For all dolphins, Their dorsal fins are just like a fingerprint. The print on the fin has unique pattern, shape or colour (just like our fingerprints). This identifies the dolphin.
Here is a table of different types of dolphins:
