Science fun!

Hi everyone! Sarah-Jane here.. I hope you are all well and keeping safe.
As we have been grateful to have such nice weather over the weekend, I decided to get my lay z spa set up.
However, the setting up is the difficult part and it actually ended up turning into a bit of a science experiment, (this is a really useful tip if you have one of these at home!)

As you all know, most swimming pools have a chemical called chlorine in it to clean the water of any bacteria and germs. However, in order to be able to use the water in the spa, we had to test to see if it was safe. This is called testing the PH of the water.

I had to improvise as I didn’t have any PH paper to test my water, so I used to magic of google to find an alternative and this is what it gave me…

First, you cut up or grate your red cabbage and place it into a clear glass bowl. Then boil about 2 cups of distilled water in a separate pot and pour the boiled water over the cabbage(adult). Stir occasionally with a wooden spoon and leave the cabbage in the water for around half an hour..

A chemical reaction will then happen causing the cabbage to turn the water to a purplish red colour. Then you strain the liquid. This will be used as what you call a “pH indicator solution”

Pour a small amount of the water you are testing into a separate clear plastic or glass container, put a few drops of your purplish solution into the water you are testing.

The water colour will change and either give you an acidic, a neutral or a basic alkaline measurement. Our water stayed purple, meaning it was alkali so was not safe to use in our lay z spa.

To ensure that our experiment wasn’t affected by anything, we added vinegar to our purple solution which changed to pink/red, meaning it was acidic. This confirmed that our experiment worked! Yay!

This is a really fun experiment to do and can be done to test any type of water or liquid such as vinegar, fizzy juice, soapy water and milk, not just if you have a hot tub in your garden! The children will enjoy watching the colours changing and being able to match it on the pH colour chart.

There are some more experiments that can be done using the red cabbage indicator..

Have fun everyone and be sure to share your discoveries with us on our Cart Mill twitter!

Miss you all and hope to see you real soon, Stay safe!! xx

Apple printing!

The toddlers have a fantastic new tree inside their playroom. They decided it should become an apple tree with lots of green and red apples on it. We used cut apples dipped in paint to create some lovely apple prints. We discussed the different parts of an apple and that the stem is what holds the apple to the tree. Some children wanted to add brown stems to their prints. We were surprised to find out that the stem is the only bit of an apple you can’t eat!! The children are looking forward to cutting out their apples and hanging them to our tree once they dry.

Our Very Own Cart Mill Forest

The children had spent the morning at the forest hunting for different types of seeds and brought some back to the centre to show their friends. Some of the children were very inquisitive and wanted to know what all the seeds would grow into.

We decided our favourite was the beech nut as it looked like a baby hedgehog. One of the children noticed that one of our beech nuts was starting to open and we could actually see the tiny seed inside. Val found another beech nut that had opened completely which the children were able to harvest the seed from. They then went to our mini forest and planted it to see if it would grow next year.

We are so lucky to be able to watch our forest grow every year. So far we have; oak trees from acorns we planted last year, apple trees from seeds we gathered during snack and cherry trees that we have grown from cherry stones. The children love learning about nature and are developing their own nurturing skills by caring for their plants.

What seed is this?
It feels fuzzy.
This one is open.
Look at the tiny seed!
Our miniature forest.

Is the hole deep enough?
We need to cover up the seed.

Power of Attraction

Today some of the children spent their time investigating magnets. They had fun exploring which items were magnetic. They discussed the items with each other and tried to guess which ones would “stick” before testing their theory out.

After a while, they noticed that when two magnets were put together they either “stick together” or were “pushing away”. We discussed poles and how magnets attract or repel each other. They tried different shapes of magnets to see if the same thing happened.
