Science spin
Today I went to my science spin and it was about Ratites.I found out in this spin that ratites aren't a single bird they a group of flightless birds.Then I filled out these questions.
What are ratites? What are some named examples of them? Where are they found in the world?
|
A ratite is any of a diverse group of large, flightless birds of the infraclass Palaeognathae. The systematics involved have been in flux.
|
What are common features of ratites?
|
Ratites are different from the flying birds in that they needed to adapt or evolve certain features to protect their young.
|
Why are ratites (mostly) flightless?
|
They have no keel on their sternum without this to anchor their wing muscles they could not fly even if the were to develop suitable wings
|
Case study - NZ ratite
For either the Moa or the Kiwi, carry out some further research to answer these questions:
| |
What is the scientific/Latin name for your bird?
|
Apteryx (kiwi)
|
What is the timeframe for your bird? (When are they thought to have arrived in NZ? How have their numbers changed over time? Are they now endangered/extinct?)
|
They arrived in New Zealand around 39 million years ago and are still alive.
They have become endangered and recently humans have taken action.
|
How many different species of your bird existed)?
|
6
|
Do we know what kinds of foods they eat/ate?
|
Kiwis are omnivores. Their muscular stomach usually contains grit (like dirt) and small stones, to help in the digestion process.
|
Are there any special features or characteristics about your bird?
|
An average of 27 kiwis are killed by predators every week.So over time they will be gone from our mainland.
|
What is a predator to your species/what caused it to die out?
|
stoats, ferrets, weasels, rats, possums, cats and dogs
|
Whereabouts within NZ is/was the species of your bird found?
|
Brown Kiwis are found in forested areas in the North Island,Fiordland, South Westland and Stewart Island. And spotted kiwis are found up North in the South Island on offshore islands and forests.
|
Any further questions about your bird?
|
Was there any other kiwis before the ones now?
|
These are all of the answers I could find and there were extensions but I didn't have enough time so there is some follow up for it.
Technology spin
After the science spin Nicola, Jacinda and I went down to the library for floor time and started doing our follow-up work I did 4 maths buddy tasks and some other work too. After floor time had finished Jacinda and I went to our spin and then Bailey came too. We started on sketch up and had to do a replica of the Art Gallery break out space I wasn't there the week before that so I had a lot of work to catch up on but I got it done and nearly finished doing the finer details. Now I just have to do all of the furniture. The reason why we (Jacinda, Bailey and I) are making a replica is because for the last couple of weeks we have been making an uninteresting objects museum, so what we did was go around the school and take photos of uninteresting objects which was hard because we all had different opinions. Once we had finished taking the photos we started making a site and putting all of the photos on it and a description with it. So we are making a replica so we can make the Art Gallery a museum of uninteresting objects.
