Science - What's the Matter?

Being scientists is a lot of fun.

This week Kōpapa East had a break out day.

We mixed, we heated and boiled ingredients.

In a pot mix 1/2 cup sugar 

with 1/4 cup golden syrup.

Bring to the boil.

Add 2 tsp baking soda

Watch it fizz and foam. Turn it out.

And then we had to be patient and wait
and wait a bit more for things to cool.

Yummy hokey pokey

Then we went home and asked our mums
if we could make some more hokey pokey.

'What's the Matter?'

We are learning how substances have physical properties that can be described. When substances are mixed, heated or cooled chemical changes may occur.

In Room 7,8 and 9 we have explored the scientific process this week and performed experiments where solids, liquids and gases change their state.

We made jelly which changed from a solid to a liquid when we added hot water, then went back to a solid when it cooled.

We turned cream into butter by shaking it in a jar for a long time!

 

We hypothesised that sugar might explode when we add baking soda.  It didn't explode but it did fizz and bubble.  Hokey Pokey is delicious and fun to make!
