All in the name of science

Today we decided that we were going to complete an experiment in the snow. This was conducted at the grass area behind Cart Mill where we wanted to find out who could go further in the snow! It was a very serious experiment which involved a group of children, and also a couple of CDOs, taking turns to slide down the snowy slope and see how far they got. We also decided to investigate if we travelled further on our puddle suits or on some black bin bags. The results of the experiment clearly showed the bin bags made us all go faster and the bigger ‘children’ went further!

And the winner is…

Exploring properties of Ice!!

The children have been developing their observation skills through exploring blocks of melting ice outdoors. They discussed and investigated some of their findings about the properties of ice. They  also predicted how long it would take to melt the ice. They decided to experiment with different methods of how to make the ice melt.

Firstly they used cold water to make the ice melt and their second choice was using warm water to see if the ice would melt faster. The children were excited to see the ice melting and discover what letters were hiding inside.  Everyone was able to work cooperatively with their peers. The children have also been developing their vocabulary through touching the ice and describing the appearance of it, some of boys said it was  “smooth” and “slippery”.

“It makes a cracking sound when i put water in”
“Look the ice is getting smaller”
“I can see the letters coming out”

“It feels cold”
“There is more water in the tray now”.

Science Experiments

We continued with our theme from last week ‘Ada Twist Scientist’ and have encouraged the children to experiment with oil, coloured water, vinegar and baking soda. The children mixed the oil and water and observed that the substances did not mix.  The vinegar and baking soda experiments gave the children a surprise.  They discovered that they have a strong reaction when mixed together – an explosion.   The children had a most enjoyable time asking lots of questions and most of all having fun.

Bogies!

As part of our Book Week Scotland scientist theme the boys and girls were curious to find out just how do our noses work?

First of all we typed our question into google: How do our noses work?
We then watched a video which explained how our noses work. why we have hairs on our noses, and why we have bogies!
We learned that the hairs in our nose trap all the germs and stop them coming into our bodies! We also learned that all the germs come out of the trapped hairs when we blow our noses.

The children then decided they would like to make their own bogies to play with. Yuck!

We mixed hot water, gelatine. green food colouring and liquid glucose together to make the bogies.
It was very sticky so we had to mix really hard!

The children had great fun playing with the sticky, messy bogies!

Finally we explored our favourite good and bad smells.

Why did the spider come inside?

This week is book week scotland and we are focusing on the book ‘Ada Twist Scientist’ by Andrea Beaty.  Ada is a very curious girl who wants to know why things happen. Recently a large spider came into the Family Centre and the children wanted to know why the spider had come in.

The children were made aware of different types of insects and what they eat. They were then aware that dropping food on the floor attracts flies and as spiders eat flies the spider had come in to the centre to eat the flies.

The children then were given specimens of insects to examine and made representations of them with playdough. The very curious children had lots of fun looking at the insect specimens and making playdough models.

Science in action!  Play allows the child to research.

Spooky Experiments in the Garden

The children were wondering what they could do with the leftover pumpkins. We always encourage reusing and recycling in the centre so thought that they would make the perfect witches cauldron. The boys and girls added paint and vinegar and mixed it together to make lots of lovely colours and then they added the secret ingredient (bicarbonate of soda). They squealed with delight as the pumpkin erupted. The children enjoyed their scientific experiment so much that they ……

Mix our potion in the pot
Add some secret ingredients…
say the magic words…
wave the wand…
and watch the pumpkin erupt!

they even suggested trying the same experiment on a larger scale so watch this space…

Double, double toil and trouble!

Is it nearly Halloween?

Well it’s all gone a bit spooky in Cart Mill this week.  The witches and wizards have been creating magical potions of all sorts of toil and trouble.

Song of the Witches from Macbeth by William Shakespeare

Double, double toil and trouble;
Fire burn and caldron bubble.
Fillet of a fenny snake,
In the caldron boil and bake;
Eye of newt and toe of frog,
Wool of bat and tongue of dog,
Adder’s fork and blind-worm’s sting,
Lizard’s leg and howlet’s wing,
For a charm of powerful trouble,
Like a hell-broth boil and bubble.

Double, double toil and trouble;
Fire burn and caldron bubble.
Cool it with a baboon’s blood,
Then the charm is firm and good.

I wonder?

The children have been carrying out some experiments. Yesterday they tried mixing mento’s with coke to make a volcano…it didn’t work!

Next they decided to light the fire pit and toast some marshmallows. Sticky but yummy!

Then the decided to create their own Volcano. Bhavin and the other children are going to try bicarbonate of soda and vinegar tomorrow. I wonder what will happen.
