The World Up Close

Today the Year 4 Science Club students used the digital microscopes to view the world up close.  We could magnify objects to make them 100x bigger.

It was so cool.

Magical Mixtures Again

This is an old favourite lesson and this week the Year 3 and 4 Science Club joined forces to have some fun.

Mixing the 2 powders together.

Carefully measuring the powders.

Working together to get the mixture right.

Wow!  The mixture is bubbling and the bag is filling up with gas.

This mixture turned green and it got really hot.

Stacking Coloured Water

Today in Year 4 Science Club we learnt how to stack coloured water. 
We found out that water with lots of salt in it is more dense (heavier) than fresh or less salty water.
Some of our coloured water had lots of salt in it.  And some of our coloured water only had a little bit of salt.

We had to figure out which colour would float on top and which colour would sink to the bottom.

Sharnia learns how to trap the coloured water in the straw.

First we tried two colours together to see which one would float.  We recorded on our sheet a tick if the colour floated on top.

The boys were really good at this.

Next we had to work out which order to put the colours so they all stacked on top of each other.  Louis was the first to figure this out.

Jackson got it too!

What colour is a black marker?

Today in Year 4 Science Club we were learning about what colours a black marker pen is made from.

First we cut out a circle of filter paper and cut a tiny hole in the middle.

Then we put a wet pipe cleaner down through the hole and into a cup of water.

We watched to see what happened.

We saw that the colours started to separate out of the black ink and spread out onto the paper.

 Where did the colours come from?  

 We think that the colours came from the black felt tip pen.  Black is made from lots of colours mixed together.
