Comparing Bucket Buddies’ Findings
By Cameron

The 6/7 class were collecting macro invertebrates to compare our data with other schools from different countries. My hypothesis was that our data would be different because we are in a different part of the world. The things we caught were:

Water scorpion 1|
Caddis fly larva 2
Damsel fly nymphs 4
Dragon fly nymphs 1
Fresh water shrimp 6
Leech 1
Seed shrimp 1
Yabby 1
Water boatman 1
Water spider 5

Some macro invertebrates were the same as what we found, others were not. This was different from my hypothesis.

Comparing Bucket Buddies’ Findings
By Rachael

The Year 6/7 class did Waterwatch so as to compare our macro invertebrates’ findings with other schools’ results. My hypothesis was that our data would be the same as other schools, but a smaller amount of macroinvertebrates.
We found:

 Water scorpion 1
Caddis fly larva 2
Dragon fly nymph 1
Damselfly nymph 4
Fresh water shrimp 6
Seed shrimp 1
Water boatman 1
Water spider 5
Leech 1
Yabby 1

 It appears there was range of  macroinvertebrates found and also quantities varied. Some macroinvertebrates were the same as what we found but other was not. For my hypothesis, I found it to be correct.

                                                                                       Final Report

The macro invertebrates I found in my pond were similar to other parts of the US and different countries. My first hypothesis was that there would be different macro invertebrate organisms in different places in the world. This hypothesis was not proven to be true, because the other samples had similar species. My second hypothesis was that in warmer climates there will be different macro invertebrate organisms than in the cooler climates. This hypothesis was not proven, because the samples from different were all similar.  A conclusion I drew was, that macro invertebrates can survive in many different climates and that similar species of macro invertebrates live in all places that samples were collected.
