Ranger for the Day

Even on the holidays the students from EHS are out enjoying science.  Who did I spy on display at Nga Manu Nature Reserve but Harry and Ollie  - who had been Rangers for the day.  I wonder what they did?

Well done boys!

What does a Pukeko eat?

Yesterday I visited Nga Manu Nature Reserve and got the chance to see some beautiful birds up close.  As I was filming this Pukeko I noticed that they had caught their dinner.  But what is it?

Sensational Slime

My slime was slippery.  The ingredients were Borax, food colouring and PVA glue.  The ingredients were all liquids.  The PVA glue was gooey and sticky to start with.  When I added the food colouring it changed colour.  When we put the Borax in it and mixed it was floppy and it was tun to play with.

Seeing the world up close!

Our Year 1 students have been seeing the world up close through our magnificent microscopes.

I can see my hair.  It looks like string.

I can see the loops in my jacket.

I can see lots of different colours in my hair.

Does it Dissolve?

Sometimes when you mix things with water they seem to disappear.  But where have they gone?

For example - when you mix salt with water you can't see the salt anymore.  We say that the salt has dissolved.

When the water and the salt are mixed together the salt crystals get smaller and smaller.  They dissolve in the water to make a solution.  We can't see the salt but it is still there.

The Year 3 and 4 students did an investigation to find out which substances would dissolve in water.

The tea leaves did not dissolve.  They just floated around in the water.

The drink powder did dissolve.  We couldn't see the little crystals anymore.  They water changed to a green colour.

The sugar mostly dissolved.  Some of the crystals took a long time to dissolve.

Magnets Are Magnificent

Over the last 3 weeks our 5 year olds have been investigating magnets.  They learnt lots of things.

• Magnets can only stick to metal.
• Magnets can stick to other magnets.
• Magnets can push other magnets away.
• Magnets can work through things but only if they are strong enough or the object is thin.

Look at D1's amazing blog to see what they did with magnets.  D1 Dragons.

Silver Beet Smoothies!

The unappetizing, sickly green gloop looked up at us. We decided to risk a sip... The silver beet smoothy was surprisingly delicious!

Each desk group in G4 had made their own smoothy recipe (but the main ingredient HAD to be silver beet), we all used the silver beet grown in our class garden and fruits from home. Our ingredients had been prepared earlier in the day

In our smoothy we included silver beet, kiwifruit, strawberries, bananas and a bit of water to blend it together. We watched in excitement as our smoothy got beaten together. We watched the solids liquify in the blender. When the smoothy was mixed we each poured some into our cups.

It was a wonderful experience that we all enjoyed! Many of us liked the smoothy so much we promised to try it at home!
