Sedimentary Rocks

Sedimentary rocks are formed from broken down bits of other rocks or even from the remains
of plants or animals. The little pieces collect in low-lying areas by lakes, oceans, and deserts.
They are then pressed into rock by the weight of the materials around them and on top of them.

Metamorphic Rocks

Metamorphic rocks are formed when sedimentary or igneous rocks are affected by great
temperatures and pressures. They do not melt, but the chemicals they contain may change
their crystal shapes. The name metamorphic comes from Greek words meaning “change
of shape.”If there is a serious amount of pressure or heat, these stones undergo
metamorphosis, harden and create new crystals! This happens over time, and isn’t instant.
That’s pretty interesting.

Examples of metamorphic rocks include anthracite, quartzite, marble, slate, granulite,
gneiss and schist.

Igneous Rocks
Igneous rocks are rocks that have formed by the cooling and hardening of molten lava or

magma. When magma comes out onto the surface of the Earth, it is called lava.
Lava cools down to form rocks such as tuff and basalt (extrusive rocks).
Also, the magma may slowly cool down to form rocks under the surface (intrusive rocks).
An example is granite.

Igneous rock is formed in two ways.

• Igneous rock formed from magma that has become solid inside the earth is called intrusive igneous rock. Intrusive igneous rock cools slowly because it is inside the earth. Examples of intrusive igneous rock types are gabbro, diorite, and granite.
• Igneous rock formed from lava that has become solid on the outside of the Earth is called extrusive igneous rock. This can happen because of the eruption of a volcano. Extrusive igneous rock cools quickly. Some extrusive igneous rock types are basalt, andesite, rhyolite, tuff, obsidian, and pumice.

Volcanos

There are three main types of volcano in New Zealand:

• cone volcanoes (like Mt Taranaki)
• caldera volcanoes (like Taupo)
• volcanic fields (like Rangitoto)

Final Week of Term 2!

Kia Ora All,

Welcome to the final week of term two! It's been a great term, albeit it shorter than expected at the start of the year. Here are a couple of things to be aware of.

• Every term I run a BTB points auction. Over the term the students build up a bank of BTB points awarded for good behaviour, outstanding manners, great sportspersonship, excellent work habits and superb effort in their learning. At the end of the term the students use their points to bid for items which have been donated to the auction. I've asked students to bring in small items they no longer want to donate to the auction e.g., old toys, stationary items, books etc. Anything small and inexpensive is fine. The more items donated, the more fun the auction is. At this point, the auction is scheduled for Friday. 
• The Room 2 class camp will be a city experience in Nelson this year (as was originally planned, but I’ve managed to re-book the camp post lockdown). We’ll be heading over the hill on Wednesday the 2nd of September and coming back on Friday the 4th - this is week 7 of Term 3. We’ll be staying at the Nelson City Top 10. Cooking will be done on site in the kitchens at the campground. The fundraising committee is covering half the cost of this camp, so the billed total will be $85 per child. I’ll send out a finalised itinerary closer to the time as well as requests for camp parent volunteers. But for now, just pop this date in your diary and feel free to let me know if you’re planning to come.
• Homework books / times tables cards etc on Monday please!

Rock On,

Mr M

Welcome to Week 8

Kia Ora All,

The mighty Room Two have continued to heroically soldier on through their learning odyssey. Last Friday, we started back with our geology inquiry topic, which was postponed due to lockdown, and began looking at volcanoes in Aotearoa. First we talked about the three main types of volcano found here. Then we looked at some examples, found them on Google Maps and marked them in on a map of NZ which was glued into our inquiry book. We've also been talking about volcano vocabulary. If you want to know what a pyroclastic flow is, feel free to ask someone from Room Two. 

• Parent tchr interviews are in the final week of term. If you haven't booked in yet, now is a good time to lock in a interview.
• The year 2 - 4 students will be going to the Mini Outdoor Adventure Programme at Whenua Iti Outdoor Education Centre in Lower Moutere on Thursday the 20th of August.
• On Friday, almost all the kids were tested on their times tables. Friday is tables day and Monday is spelling day. Please make sure tables cards and homework book is in your child's book bag and ready for school on Monday.
• I'm trying to get the students back into the rhythm of completing their set Maths Buddy tasks weekly. I set four tasks each week and aim to check every Sunday to see how students have got on. I'm going to have a Maths Buddy points chart to celebrate kids who finish all their tasks. Completing tasks is in no way related to maths ability as I set appropriate tasks for each group or individual as necessary. Only one student completed all their tasks last week so I've extended the tasks for a few days. Students have time in class to complete tasks. It's also a good homework task for those who are interested in adding some maths into their home learning programme.

Rock On,

Mr M
