Melting Chocolate

Today we did some more inquiry learning about heat.  We melted chocolate and made shaped chocolates in molds.

First we heated some water in a pot and then we put the chocolate chips in a bowl and put the bowl on top of the water.

The chocolate started to melt quite quickly.  It looked a bit weird when some of it was melted and some was still chocolate chips.

Once all the chocolate was melted it was very gooey and runny.

We put the melted chocolate into molds and then put it in the fridge to set.

Finally, we got to eat it.  Yum!

We talked and wrote about what we had noticed happening to the chocolate.  It changed from being hard to being runny.  Mrs Harrington told us that it changed from a Solid to a Liquid.  We learned that in a solid the particles move slowly and are close together so it is hard.  When you heat a solid the particles start to move faster and move apart from each other and it becomes liquid.  Liquids can be poured because the particles can move more than in a solid.   When we put the chocolate molds in the fridge, the liquid chocolate turned back into a solid because the particles cooled down and stopped moving so fast.

We watched a cool clip here that explained how the particles change when a solid is heated.

What other things do you know that can be changed from a solid to a liquid using heat?  Tell us in the comments!

Our Matariki Korowai

Here is some more learning that we have done for Matariki (the Maori New Year).  We read a book about Matariki and used our White Hat Thinking to list all the new facts we had learned.  We then made a beautiful Korowai (feather cloak) of paper feathers.  On the feathers we wrote the new things we had learned about Matariki.  Korowai cloaks are taonga (treasures) that are often worn on special occasions and celebrations like Matariki.

He tino pai too mahi B4! 
(Your work is great B4!)

Matariki: The Star Fishes

Last week was the start of Matariki, the Maori New Year.  We read a Maori legend called "The Star Fishes" which is just one of the many legends about the seven stars of Matariki.  We acted out the story and then we retold the story in our own words.  The next day we created some amazing Star Fishes artwork.  Take a look at our fabulous work and let us know what you think!

The Star Fishes
A Maori legend about Matariki
Retold by B4

One day a mother fish told her seven baby fish “Don’t go out in the open sea today.  The giant Tataraimaka is fishing.  Be careful!”  But the baby fish did not listen to their mother.  They were busy playing tag and they got caught in the giant’s net.  The baby fish cried and cried and they made the sea salty.  Tane, the God of light, felt sorry for the baby fish.  He took them out of the net and he threw them into the sky.  The baby fish turned into the seven stars of Matariki.

Acting out the legend:
We used a net from the tennis courts as the giant Tataraimaka's net.

Some of our artwork:
We created out artworks using pastel and dye.  We had to make sure that we drew 7 sparkly stars and 7 bright coloured fish.  Some of us found drawing the stars a bit tricky, but we tried our best and Mrs Harrington thought we did an excellent job!

Captain Quake writing

Every week we read a different big book in our classroom and one day each week we write about our big book.  We read the book "Captain Quake and Big Bird" by Jill Eggleton and then we wrote some character descriptions of Captain Quake.  Here are some of our amazing stories.  We used pastel and dye to make our pictures of Captain Quake.

Ball Skills

We have been learning big ball skills for P.E. the last few weeks.  The skills we have been learning are passing, catching and rolling a ball to a partner.  Here are some photos of us out on the netball courts practising our high "rainbow" passes and rolling a ball to a partner.  We counted how many times we could throw the ball to our partner without dropping it and some of us got to more than 20! What great ball skills we are developing!
