Wearable Apron Art!

We are starting our Wearable Art Unit this week and are looking for some bits and pieces to make our art more exciting. If you have any of the following, or other items you think would be useful, we would love to have them for Thursday.  We would also like each child to bring a coat hanger so we can hang the items safely while they are being made.  We are looking for some extra pairs of hands to help with the construction of these items so if you could spare about an hour to help out, please let me know. Session times will be Friday 1st July1.45 - 3.00 and Thursday 7th July 1.45 - 3.00.

Poetry Competition - Week 10 - 7th July - 11.30 to 12.30

It's Poetry Time!!!!! Do you know a really good poem to share with the class? Have a look at the sites at the side of this blog; check out your bookcase; search the library; ask Mum or Dad; pick Grandma and Grandad's brains,  or write your own.

Over the next two weeks we will be focusing on poetry and on presenting poems.  The poem you present must be at least 7 lines long. Choose a poem that you really like. If you enjoy it, then your audience will too.  You will get the chance to present your poem to the class and the best presentation will be selected to represent the class at the finals in Week 11.

Parents/caregivers are welcome to attend the class poetry presentation which will be held in our classroom on the 7th of July from 11.30.

Coke & Mentos Geyser

Things have been fizzing in Room 19 this week. We have been investigating chemical reactions and have had lots of fun doing it.  Before we started we had to hypothesise about what we thought would happen. We used our SOLO thinking levels to make our predictions then we headed outside to see how accurate they were.

Be warned - this gets messy. Make sure you check with Mum or Dad first.

What you will need:
2L Bottle of Diet Cola
1 pkt Mentos lollies
Geyser Tube (Optional - available from Nature's Discoveries in Riccarton)

What you do:
1. Go outside.
2. Put the bottle of cola on the ground (or dug into a little pile of liquefaction!)
3. Load the geyser tube and pull the trigger OR VERY QUICKLY tip 7 mentos lollies into the cola.
4. STAND BACK.

Wonderings:
Does it work with different flavours of mentos?
Would it make a difference if we used different brands of cola?
Will it still work if we used lemonade?
Could you use other types of mints?

Thank-you to Jamie from Room 20 for recording our investigation.

Ice Cream Science!

Home-made ice-cream was a popular investigation in Room 19 today. Our second experiment achieved much better results than the first rather slushy result and the addition of some extras was a special treat in recognition of the bumpy week.

Basic Recipe
What you need
100 ml full cream milk
2 tlb sugar
2-3 drops of vanilla essence
2 cups ice
2 tlb salt
What you do
1. Pour the milk into a small snaplock bag.
2. Add the sugar and the vanilla essence.
3. Seal the bag.
4. Put the ice and salt into a medium snaplock bag.
5. Put the bag with the milk mixture in it inside the ice bag.
6, Seal the bag.
7. Put both bags inside a container and shake until the milk turns into a solid.
8. Carefully rinse the outside of the ice cream bag to remove any salty residue.
9. Eat and enjoy

Questions we have for further investigation are:

Would we still get ice cream if we used a different brand/type of milk?

Could we use different essences to get different flavours?

How much faster does the salt make the ice-cream freeze?

Would it work without the salt?

When we kept shaking it, it got softer again - is this because of the shaking or the because the ice had turned into water?

Investigate one of these questions over the weekend if you get a chance. Send me some photos of your findings and I will add them to the blog. Have fun?

Wonderings?

Can anybody else see similarities between oobleck and liquefaction?

Looking after each other!

Hi Everyone


I was very proud of everyone yesterday - once again you knew what to do, did it quickly and were very supportive of each other. I hope you are all safe as we begin our clean up again. 


Keep an eye on this blog and the school website for information  - and keep in touch via email or comments on the Blog. Hopefully we will be back in action very soon.


BIG HUGS!

Oobleck

Is it a solid, is it a liquid .....or is it a non-newtonian fluid?

This afternoon we were investigating the properties of Oobleck. Oobleck is very easy to make and lots of fun to explore. Put 1 cup of cornflour, 1/3 of a cup of water and a few drops of green food colouring into a plastic container and mix it together.

Warning: This will get messy and do NOT dispose of it down the drain.
