The very very very best fun we had

in Science was the day teacher told the class that

she was going to show us some chemical reactions.

 

Teacher added sugar to water and shook the mixture

and asked us what we thought would happen.

Most of us had a pretty good idea.

 

Then she added salt to water and shook the mixture

and again we guessed it would vanish into the water.

 

Then she asked us what would happen

if she added baking powder to water and shook it.

We all went to the yard and stood in a large circle

in the middle of the basketball court.

 

Teacher explained that she was going to

half fill a little black container,

(the type of container that camera film come in)

with baking powder this time.

 

She would then add some water.

She would give it a little shake

and put the lid on tightly.

She asked us to predict

what might happen.

 

We thought that the same thing

would probably happen again

and that the baking powder would dissolve.

 

Teacher put the container

in the middle of the circle

and asked us to stay well back.

 

Nothing happened at first.

Then suddenly the black container flew up into the air.

The lid popped off and a fizzing bubbly mixture

spilled out onto the ground.

 

We jumped and screamed

and we asked teacher to do it again

and again until the baking powder was all gone.

It certainly taught us to expect

the unexpected in science!

Calum was busy. Nice work Calum.
