WEEK 4

Kia Ora,

It has been wonderful to see the sun but the wind has been so cold....it is time to get out our winter clothes!

This week we put on our lab coats and did an experiment that Desharne chose.

We put dirty coins in some coca cola and we are going to see if there is a reaction with the coke and the coins.

Here are some of our thoughts...
Im wondering if the coke will disappear?
When the coin comes out will it have the delicious smell of the coke?
The coin will get so clear that the whole coin might become clear!
Maybe it will become clean?

Discussing our coins and what is on them.

Using a magnifying glass....you can see so much more!

Putting the coke in...

Do you remember us telling you about our visit from Naoko?

This week we put into practise what she had taught us.

When we were doing our experiment with the volcano Miss Hudson told us about another thing that we could do using baking soda, so this week we made Hokey Pokey to see if we could make the connection.

And we did!!

The baking soda reacted with the warm sugary mixture just the same way as the baking soda reacted with the vinegar.

It went all frothy and changed colour.

When we ate it we found it was very crunchy and if we left it in our mouth it felt all fizzy.

Adding the golden syrup...

Everything is starting to melt...

Adding the baking soda made the mixture change colour and then into a solid

Todays chef was Ryan...he chose spaghetti in tomato sauce .

We had to use the can opener to get the spaghetti out.

Then we put the mixture in a pot to heat it through before putting it on our plates.

Getting the lid off...

Chef Ryan in action!!

Have a superb weekend everyone!
