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

Earth Day

Tomorrow is the 50th anniversary of Earth Day and you will find lots of environmentally friendly activities on the earth day website. www.earthday.org
Although we are unable to be together, we can still look at ways to help the climate together. We are all being encouraged to go for a walk during these strange times, which is fantastic for us and the environment. There are fewer cars about making it safer to go out walking but also making the air we breathe cleaner.
How else can we help our world? One way is to plant forests so, while we are all enjoying our lovely weather we could plant our own trees! It’s really not difficult at all. Next time you have an apple, ask a grown up to cut it open so you can look inside. What can you see? Look for the seeds, I found 8 in mine! Take on old container with some drainage holes or some plant pots and put in some compost, remember to use peat free if you can! Plant the seeds in the compost, making sure they have plenty of room, then cover them up with more soil to keep them nice and warm. Give them plenty to drink, especially in this weather and then be very, very patient. Keep looking after them, watering them and keeping them warm especially if it gets very cold at night. One day, the seeds will pop their heads out of the soil and start to grow into apple trees and you will have started your very own forest! 🌳🌲🌱🌿🍎

Rainbow science with Linzi 🌈

Hi everyone!

I hope you are all well. I’m missing your wee faces and funny stories ❤️

Today I’ve been trying out some rainbow science with my kids, Seren and Keir.  I know how much the children at Cart Mill love our science investigations so, here are 2 easy ones to try at home with everyday items.

Seren got a sheet of kitchen roll and drew on it with different coloured pens – she did shapes to add a bit of numeracy into this activity – then she drew over them with black ink.

Pop it on a tray as you are about to get messy 

Keir used a spray bottle to squirt water on the shapes (good for fine motor skill development) however you can use anything so long as your wee one can drip water onto each shape.

What colour will appear?

Just like magic, every spray revealed a colour. The paper absorbed the water, moving the colour with it.  Keir enjoyed it so much we did it again with faces.

Next we tried to grow our own rainbow. Seren got another bit of kitchen roll and drew rainbow colours on each end.

She placed it into an arch shape using two cups and tried to guess what would happen. Keir poured water into each cup.

Good for hand-eye co-ordination

We watched as our rainbow grew 🌈

Look at those colours

Keir was able to relate what happened back to our previous activity and he understood the “water maked it move”.

Why don’t you guys give this a go at home and tweet us a picture of your rainbow science 🌈

Take care and stay safe, Linzi x

 

Spring is coming!

The toddlers were really busy learning about how a seed can grow into a beautiful flower. We listened to a story about growing plants and flowers and wanted to make our own.

We filled some pots with compost and added some seeds.

 

 

 

 

 

We watered the seeds in the pot to help them grow and sat them by the window for some sunlight.

We will be looking after our plants by watering them and hopefully repotting them in April when we will add them into the greenhouse in the big garden.

How Will Our Garden Grow?

Exciting times in the Cart Mill garden this week with the arrival of our new greenhouse. Michelle, Fiona and Val have been working to build this beautiful new addition to our outdoor space. Having somewhere to start our seedlings grow will provide so many wonderful experiences for the children at Cart Mill. Not only will it help explain the wonders of nature and life cycles, it will encourage children to care for and nurture their very own plants.
We have been eagerly waiting for our greenhouse for a few weeks and now the hard work begins. The shelves are up, the seed trays are ready. So, what will we plant first?

What will happen?

Happy Valentine’s Day to our Cart Mill Family!

We have been doing Valentine themed activities this week and finding out what the day means to the children.

In the science corner we’ve kept to our theme to help us explore what happens when we put paper into water. We learned new vocabulary and discussed hypothesis.

We started with paper hearts
Then folded them up

We tried to guess what would happen when we put our folded hearts into water…there were lots of fabulous theories; “it’ll change colour”, “it’ll explode”, “it’ll sink”, “ it’ll get sugary, break apart”

We placed them into water and waited to see what would happen

The paper opened back up into a heart shape.  We discussed why this happened – the paper absorbed the water causing the fibres in to paper to expand and push the paper apart.  One child asked if there was more water would it sink.  So we decided to find out and added a bowl that was deeper.  Again we tried to guess what would happen. “It’ll sink” “it’ll float” “it’ll make waves”

We discussed the difference between shallow and deep; “sink means you fall under the water”, “float is staying on the top”

Again the paper opened up “it’s opened up because we drop it in” one child exclaimed.  Another child agreed saying “yes because we put it into the wet”.

The children clapped when the heart opened up

The children continued to explore this for the rest of the morning.

Upcycling an old table

After observing some children tinkering on the workbench it became apparent that they would require some guidance on how to use the workbench and tools. So an old wooden table was brought in as a life learning experience to help the children develop an understanding of how we can re-use and fix things.

During this 2 week experience some of the skills the children have been developing are; language, cooperation, listening, problem solving, measurement, tool safety and risk assessment.

 

Working together to prepared the old table by washing it ‘to make it clean’

We all took turns sanding the table to take the’ old wood away’ & reveal the wood underneath  ‘smooth’

Measuring the table legs to make sure all ‘4 legs’ are the same size      ‘else it will wobble’

We are learning how to use a saw safely
‘only with a grown up’ & ‘look at the saw’

Protecting the table with beeswax ‘it soaks it up’ & ‘taking care’ of the table so ‘it last a long,long, long time’

We worked together to screw the shorter legs back on the table.

 

Playing with our beautiful new table  ‘ you sit on the cushions’ & ‘like this …..legs under the table’

The children are very proud of their new table ‘I did this’

 

 

Iceberg Ahoy

The children were exploring different textures in the water tray today. We had some gooey red jelly and bicarbonate of soda fizzy ice as well as some fluffy frozen shaving foam.

The children loved feeling the different textures. They were able to use great descriptive words. They could see the bicarbonate ‘bubble’ when it came in contact with the jelly. The ice was SO cold and the shaving foam was like ‘snow’. Then one child said “it’s a big iceberg!” We all watched the iceberg float around our jelly sea before it slowly melted.

Ice Science

This morning the children set up an experiment to explore the effects different materials would have on ice “It’s cold” .

Pouring in bicarbonate of soda

They added room temperature water, salt and bicarbonate of soda to separate bowls of ice and guessed what would happen. “It melts with salt because one day my Mum put salt on ice and it melt so fast” .

Casting our vote

We used counters to record what we thought, “soda will melt”.

Using our magnifying glass to get a closer look

The children watched and waited to see what would happen “it’s melting and filling up, it might go over”

The children used descriptive language to explain what they saw “the purple one is bumpy” and “The green one is smooth”.

Look what happened

The water melted the ice fastest today but the salt was a close second.
