This week in Cohort A we did a science experiment activity called "blizzard in a bottle". The idea was to mix water, paint, and baby oil, and then drop in an alka-selzter tablet and watch it make bubbles and "snowflakes". We collected empty plastic bottles during the week to use for this experiment. The reason I chose this activity is because I've noticed that the kids love to watch how different substances react with one another, and they especially enjoy watching them fizz and erupt. My favourite part of sharing science experiments with the kids is watching their reactions and hearing them guess what will happen. During this experiment, one child guessed that "when you add the baby oil, it won't actually mix with the water but it will sit on top", and they were right!
The original experiment only used white paint, to appear more blizzard-like, but I let the kids choose whatever colour they wanted and that lead to some very colourful bottle-blizzards! Once they added the alka-selzter tablets and watched it fizz, they were very curious as to what would happen if they shook the bottle and mixed all the substances together. One child exclaimed; "I want to make it as fizzy as possible and have a really crazy blizzard!" And that's just what they did.
Another child was curious about how the mixture would look when poured out into a cup, and they all agreed that it kind of looked like coloured milk! It was very cool to see the texture of the "blizzard", and how it changed as it was being poured.
The children enjoyed playing with their bottled concoctions for the rest of the afternoon and were very excited that they got to take them home and show their families what they made. We all agreed that next time we try it, we will use more alka-selzter tablets to see just how fizzy we can make it, maybe we can even make it erupt out of the bottle!
Until next time,
Snow in the middle of April was perfect for some spring ice building in Cohort A. We started off by designing what we would want to build with the ice bricks that were made by freezing water in loaf pans and milk cartons.
"I want to build a cabin! " said one child about their design.
"I want to do graffiti art! Does anyone want to help me?" Said another child to their friends.
When we got outside, Cohort A immediately noticed of the colourful ice bricks and started making guesses on what they represented. "Blue is water!" said one child to another, who replied by saying "yeah, and red is fire!" they then both agreed that green was "Earth".
Some of the children started testing out different ways to stack the bricks on top of each other, while other children wanted to test out how much force it would take to smash the ice bricks. "Let's see how many bricks we can stack on top of each other" said one child to their friend who replied with "No thanks, I want to smash them instead"
Since the weather was a bit warmer in the afternoon, some of the children noticed that the ice was starting to melt making it really sticky. The bricks got stuck on their gloves and their shoes. "Quick! Take a picture!" said one child. holding up his hand to show that the circular ice brick was sticking to his glove. "It looks like a Captain America Shield!" Then, they picked up a bigger ice brick to see if that would stick to his glove as well. "It is pulling my glove off!" he exclaimed.
Although the children were not able to build exactly what they wanted, they explored different ways to use the ice bricks by creating new designs and testing out the idea of force to smash ice.
Next time, we will make even more ice so that the children can build all of their big ideas they have planned!
As the snow fell down in mid-April, we decided to take advantage and make snow sculptures. Before we got started, I prompted the children with a question: If we built a big huge snowball, could you guess how tall it is? As they started to build, the children made their guess on how tall they thought they were and then we took out the meter stick to allow the children to see if we were right about their predictions.
In the process of creating our sculptures, we observed that the children ended up splitting into two different groups to build their snow sculptures. One group was called Team Raelien because she was helping them, and the other had Leah helping so they called themselves Team Leah. The children decided to see what team could get the tallest tower in only five minutes! While we were measuring to see what team had the tallest tower, the children measured team Raelien to have the tallest tower, but then also decided that team Leah had the creepiest. All the children worked well together on both teams while building each sculpture, I overheard the children discuss how they would place each snowballs on the sculpture so that they didn't fall. One child suggested that they needed to pile up the snow on one side so that it didn't fall over! Both teams decided to take this one step further by adding some life to their sculpture. Meet our new friend Remi below!
The children expressed that they were happy with the end result of their sculptures, especially when adding some colour to their design! One of the sculptures was made into a Pokémon and the child was excited to describe in the video exactly how they did it, and what exactly the Pokémon was called.
Some children in our other cohort went in a different direction with this activity, they used the colour to add graffiti art within the forest and here are a few designs they did with food colouring.
In conclusion, the children had a blast playing in the snow while creating their snow sculptures and graffiti art. It was great to see the children have so much fun working together and sharing their ideas, but the fun didn't stop there! The next day, the children buried one of the educators in the snow and each other as you can see in the last two pictures. Snow in April? No problem, we will still have fun!
