Science@Play - Five Senses

Our second session of Science@Play, which was at the end of March, was on the Five Senses. The children had a sensory galore with ten stations for them to play, explore, create, and experiment. We couldn't cover all ten stations but I think we went to eight of them. 

The first station we went to had kinetic sand on a mat. I know the little girl is usually very hesitant of getting herself dirty so early into a playdate before she has warmed up. As I had expected, she didn't want to touch the sand at all. Oh well.

Moving along we went to a station that had colourful plastic eggs in an egg tray. The children could shake them to hear the contents and guess what were inside. Or they could shake them to match two eggs which had the same contents. Now that's a mess-free starter activity which suited her just fine.

Next was a fun station for the children to explore with shaving gel, paint and glitter. After spraying some gel into a tray, they decorated it with different coloured sparkly glitter before deciding to explore further with their hands. Since she had warmed up I assumed, the little girl was ready to get her hands dirty.

 Let's get messy!

After washing the gel and glitter off her hands, we went to the next station for some play with scented dough. She spent quite some time there playing together with her friend. And while she was busy with the dough and cookie cutters, I spent some time catching up with friends.

While she was busy with the dough, I looked around at other stations. There was a station with colourful yummy-looking jelly for the children to eat. They could even play with the jelly if they wanted to but the little girl wasn't interested in it.

There was another station where the children could experiment with water in test tubes to hear the different pitch that they make when struck with a tuning fork. Only thing is, I didn't think they were given a tuning fork. A tuning fork usually has a shorter handle with longer prongs but what they got was something with a long handle and very short prongs. When I tried hitting a test tube of water with it, it just made a dull thud. Hmm.. There was a shaker and a xylophone too for the children to explore but the children were more than happy to just transfer water using the pipettes.

After some time, I decided to lure her away from the scented dough and asked if she wanted to make a rice shaker. She still held a piece of dough in her hand while filling her shaker with rice. Then I taped both ends of the shaker with craft paper and tape and we got for ourselves something to make music with.

Next was a station to make a sensory board. She probably missed out one or two materials but she got nine different materials neatly taped onto her board.

And while almost everyone else had opened up their lunch boxes and were munching away, the little girl was suddenly attracted to the water and pipettes. And so she sat there transferring water from a plastic cup into glass test tubes. She had used a transfer pipette just the day before at a playdate session with Growing with Colours so she was probably enjoying the new instrument. 

Though it might look rather mundane to be just transferring water, but I was grateful that the little girl could control the pipette well enough to guide it into the small opening of the test tube without spilling water. At times like this, I thanked Him for giving me such golden opportunities to watch my daughter learn and practise a new skill she had picked up. That very day, I asked my brother-in-law if he could get a few transfer pipettes for the little girl and he did! Now we use those pipettes mostly for watercolour art.

I know we missed a few stations that day but it's okay. One of it was to make a paper tambourine and another to taste foods with different tastes. There's no point in rushing her through and I would rather she has ample time to enjoy each activity thoroughly before moving on. I remember going home really happy that day for a fulfilling noon with my daughter. 

Science Playdate - Colours

Last week we were invited by Umar's ummi to a Science playdate at their home. Knowing that his ummi is a closet-mad-scientist-turned-teacher, I was excited to see what she had in store for us. And what she had prepared for the children was simply amazing!

Teacher Za took pictures of the children and while we were not looking, she printed and pasted the pictures to make personalised name tags for the children. How thoughtful! During circle time at the start, each child went to a box to take out a name tag to present it to the child whom it belonged to. But instead of saying Hello, they greeted each other with Assalamu'alaikum and Wa'alaikumsalam. It was like being in the Islamic version of Julia Gabriel!

Then the children started their first activity. Some milk was poured into an aluminium tray. They were then introduced to four bottles of food colouring and the colours purple, blue, red and yellow. Teacher Za then squirted a bit of food colouring onto the milk and picked a cotton bud soaked in dishwashing liquid. She placed the tip of the cotton bud on the food colouring and the children, and their mothers too, were amazed when the food colouring dispersed to make pretty patterns on the milk. The children then got their own materials to make their own milk art.

After the children had made their pretty patterns on the milk, they were given a piece of paper to place on the surface of the milk to get some food colouring on the paper. When the milk has dried, you get a piece of art on paper.

Next, Teacher Za took out a bottle and introduced the children to a funnel. She poured cooking oil to fill about half the bottle, followed by water up to about three-quarters of the bottle. She sprinkled glitter into the bottle and squirted about ten drops of food colouring into the bottle. The children were all excited to start but she wasn't done yet. She dropped half an effervescent tablet into the bottle and you get a lava lamp! The children then got their own bottles and funnels to have a go at making their own lava lamps which they got to take home.

It was then snack time and time for some free play and for the mothers to catch up with each other. Teacher Za had earlier in the day swapped her mad scientist's lab coat and safety goggles for a baker's apron and mittens and baked for us chewy oat biscuits for the children and baked pasta for the mothers. MasyaAllah how fortunate we were to be served hot food after some activities. I know for sure the little girl enjoyed the pasta as she ate many helpings of it.

After that we went out of the house for the next two activities as it would get a little messy. Teacher Za had laid out cloth mats for us with her materials at the side. She introduced baking powder to the children which she poured some into a bottle. Then she squirted some food colouring and dishwashing liquid  into the bottle and, with a funnel, she poured some vinegar into the bottle. 

The children erupted with excitement when they saw the coloured bubbles rising in the bottle and flowing out of it. They then got their own materials to make their own volcanoes. If you put a lot of baking soda in the bottle, the reaction can go on and on as long as you pour vinegar into the bottle. The children were enthralled by it and Umar was busy taking snapshots of his blue volcano

This experiment totally reminded me of the volcano I had built when I was a primary school student, complete with brown plasticine for the "mountain" to conceal the bottle inside it. I remember it was on display at a Science fair in another school, together with some of my charts and another of my experiment with a chugging boat. Those wonderful Science Club memories!

After we had cleared the bottles and trays away, Teacher Za took out some colourful ice lollies for the children. For a while, they thought those were edible ice-cream but they were not! They were frozen mixtures of paint and water and were meant for painting. So they immediately started painting away with the ice lollies.

Then Teacher Za introduced them to syringes and told the children that they could use them to squirt some oil on their painting. The little girl had played with syringes before, usually to feed medicine to her stuffed toys, so she immediately gave it a go. After two squirts of oil, I realised that the oil caused some globules of paint to separate from the rest, creating pretty paint patterns.

After we had cleared up the mess outside, it was more free play for the children and we even stayed on for dinner as the kids were famished after all that fun. We were the last to leave but the little girl didn't want to go home. It has been quite some time since we last had a playdate with Umar and his ummi and I think the little girl missed playing with them. She and Umar used to play together all the time. She said that she wanted to stay with Ummi but I knew Ummi was too exhausted to play with her and we had to leave for a talk that night. 

I couldn't be more grateful for all the hard work that Teacher Za had put in for the children and the mummies without expecting anything in return. All we could do is to du'a that she'll be blessed with more than she had given. You can read her blog of the Science playdate to see more pictures and read up on the Science behind the experiments from the teacher/mad scientist herself. 

I love the children's sense of wonder and excitement as they were trying out something new and observing the reactions. May their sense of wonder and zeal for learning grow with them. Ameen.

Science@Play - Weather

Last month, we attended our first session of Science@Play by Dr Rufaihah and her team from Granada Academy. The theme was on Weather and it was the second monthly session of Science@Play. It was conducted outdoors at Bishan Park which was just perfect as I love outdoor playdates. Nothing like the sound of birds chirping, the feel of the gentle breeze, and the sight of trees around us to add to the experience.

We arrived a little late and by the time we had settled down, the children were listening to a sharing on different types of weather. A few inflatables were passed around of the sun, snowflake and raindrop after the discussion, followed by an activity on making a weather mobile.

I felt that this activity was more suited for children who are probably four and above; who are able to cut, thread strings through a hole, and tie knots on their own. As the little girl is only turning three this year, she couldn't complete it on her own but I tried to make it as child-centred as possible by letting her cut the strings and thread them, and choose where to hang the pictures. By the time the activity had ended, we had completed hanging only three pictures but that was totally fine. We kept the other two to complete the mobile at home.

The pretty weather mobile 

The next activity was to make a tornado in a bottle. An empty bottle was half-filled with water then a special cap was screwed onto it so that another empty bottle could be fastened on top. Then the two bottles were quickly overturned and given a quick swirl so that the water in the top bottle would spiral down in a tornado-like motion.

Of course when I got home, I had to find out why a vortex was created in the bottle. We all know that when water flows out from a container, air has to enter to take the space previously occupied by the water (now that's a textbook answer or something students memorise for their exams). That is why when we pour, we hold the bottle at an angle so that the water flows out smoothly as air is able to enter at the same time. Or when we make a hole in a milk can, we make another hole so that air can enter while we are pouring out the milk.

Have you tried pouring out water while holding the bottle vertically? Well I have, as an experiment of course. The water gurgles out or comes out in spurts as air and water have to take turns going in and out respectively. And if sufficient air doesn't get to enter, the bottle will slowly collapse so that there's a smaller space in it. Amazing stuff! Once students experience this, they'll never ever forget the lessons on Matter.

So back to the tornado in the bottle. The bottle was given a swirl to create a vortex with a hole in the middle so that air can come up the bottle and water can swirl into the bottle below. Now that totally makes sense, doesn't it? Without giving it a swirl, and the vortex, the water will not flow down smoothly due to the explanation above. You can read about the tornado in a bottle at Steve Spangler Science to create your own at home!

Next was an activity which got the children all excited as it was time for some messy play! They each got a bowl filled with some water. A spoon of white powder was added and voila, the powder erupted into fluffy "snow"! The instant snow, which is a polymer, felt cool to the touch and wasn't clumpy or sticky. The children poured it out, threw it on themselves or squished it with their hands. My neat little girl, who loves to scoop and transfer, immediately scooped it back into the bowl with a spoon after it was overturned.

I think the time given for the activity was too short as the children would have loved to play with the instant snow for a longer time. I am trying to get my hands on some of that instant snow powder. I would place the snow in a large basin or at the water table, with some scoops and containers, and I know the little girl would be absorbed in it for an hour or so, for many days.

Playing with instant snow

The last activity for the day was an exploration with dry ice. Some dry ice were placed in measuring cylinders, water was added, and the children were amazed with the bubbling in the water and white smoke that escaped. Immediately the children grabbed the metal tongs to add more dry ice to the cylinders. Dry ice is frozen carbon dioxide so when it reacted with water, the gas produced is a combination of carbon dioxide and water vapour. The smoke that you see is a cloud of tiny water droplets.

Food colouring was added to the three cylinders to add to the excitement and the children continued to add dry ice. What they forgot to do though was to add water to the cylinders as without water, the above reaction would not take place and bubbling and smoke would cease. Finally, some dishwashing liquid was squirted into the cylinders and soap bubbles erupted from them. There was no way to contain the children's excitement after that. You can read some dry ice experiments at Steve Spangler Science to do your own at home!

Of course there was science behind the tornado in a bottle (vertex), instant snow (polymer) and dry ice (sublimation and chemical reaction), but the children, aged 2-6, were too young to understand those. If we were at home, I would probably tell a simplified explanation to the little girl. I'm looking forward to the Science playdate by Umar's ummi as I know Teacher Za will surely give a brief scientific explanation for the activities.

The next session of Science@Play, with the theme on Five Senses, will take place on 31st March at Bishan Park. Can't wait for the next one! Looking forward to see you there!
