Baking soda and vinegar… It just never ever gets old. This very simple fizzy eruptions activity has been a hit with so many of our little friends and guests over the years. And it doesn’t matter if they’ve just turned two or they’re nearly eleven years old – everyone who has come over when I’ve had this set out for a co-op meet-up, play date, or birthday party has pretty much loved it. I mean what’s not to love about colourful fizzy eruptions that leave your play surface looking just like that of the moon, right?

Here’s the simple-as-can-be set-up… A plate of baking soda (or soda bicarbonate for our UK friends), several little jars of white vinegar coloured with liquid food colouring, gel food colouring, or liquid watercolours {my personal favourite because of the fact that they’re fully washable}, some pipettes, and a play tray to contain the mess {this one from Ikea is our fave}.
At nearly 3 years old, Sam has just really nailed down how to successfully use pipettes, but Miss G was using them when she was freshly 2, so it just depends on the kiddo!
That being said, kids who haven’t mastered pipette use can totally still create fizzy eruptions on their own! Instead of giving them the usual jar / pipette combo, just put the coloured vinegar in old glue bottles, any other squirt bottle with a small opening, or old liquid soap bottles with a pump and let them squeeze or pump the vinegar onto their plate of baking soda.
If they’re able to use a pipette, it’s as easy as squeeze to collect coloured vinegar…
Then squeeze to release the coloured vinegar onto the baking soda base and watch the fizzy eruption magic happen!
When the fizzy foam settles down, you’ll be left with the coolest coloured spots that look just like the moon’s surface {hence why we sometimes call this ‘moon painting’}.
Now if you really want to take things to the next level {like Sam does ALWAYS}, you may want to try the triple pipette method {patent pending – HAHA!}
Simply shove all three of your pipettes into a single jar, squeeze up as much vinegar as humanly possible…
And enthusiastically squeeze them out onto your baking soda in order to create the biggest fizzy eruption possible. The more force the better, really.
I mean, just look at how fun it looks!!
And when you’re nearly done, may as well just dump the rest of the vinegar out, right?? ‘Papa says sam can do it’, I’m told. Hah!
But in all seriousness, when the entire plate is flooded in vinegar like this, most often you can dump off the liquid and use the remaining {wet} baking soda below for round 2. I mean you may as well get as much bang for your buck as possible, right? {This is especially important when you live in Kuwait and you’re buying 45 of these tiny 100 gram containers of baking soda at a time.}

Because there were a couple of butterflies enjoying the orange when we were ready to take them outside, I decided to make the somewhat risky move of taking the orange slice, butterflies perched atop, outside on its own. The hut was positioned close to a door, and luckily neither flew off before I safely got outdoors. In fact, this little one continued to slip up juice from the orange for quite a while, even once completely free to go.
With our two hungry butterflies already outside and the rest of the fruit removed from the bottom of the hut, it was time to take the entire enclosure out. Though I’ve done it on my own in the past, this truly is a two person job. I gently shooed the butterflies hanging out near the bottom of the enclosure up to the top, collected the four flaps at the opening, and Brad unpinned it from the ceiling. Walking very slowly in order to keep the enclosure taut and not squish any butterflies, we brought the whole thing outside, laid it on its side in the grass, and opened up the bottom.
While you might expect them to be in a rush to fly off to their freedom, for the most part, they’re not. Except for one, I retrieved the butterflies from inside the hut by gently coaxing them to climb onto my finger, then brought them out into the open.
The cool part is that most will hang around a while, giving you a great opportunity to see them up close without mesh intruding on your view.
This is also a great time for little ones to ‘hold’ a butterfly too. All you have to do gently coax the butterfly {without touching their wings obviously} into climbing onto your finger, then place your finger on the edge of the child’s hand to make a careful transfer. You can do it lots of different ways, but I personally like putting the butterfly on the topside of the child’s hand as it prevents the gut reaction of closing the fingers around the butterfly when it decides to fly off.
When they decide to go, some will fly off high into the blue sky until you lose sight, while others will land on a nearby plant. Another possibility is that they’ll fly for a bit and decide to touch down on the grass, so be sure to be mindful of where you’re walking.
I’m so, so glad that we decided to do raise butterflies with Miss G this year. As each butterfly eventually made it’s way off, Gracen would call out, “Buh bye, butterfly! Have a funny day!” – a happy goodbye. It’s been an amazing learning experience, and without a doubt, she’s learned a ton. She uses all kinds of new words now and can tell you all about the butterfly life cycle and butterfly parts. Best of all, she’s learned this all in a hands-on, meaningful way without actually realizing that she was learning. ☺
With our butterfly enclosure ready and our first chrysalises ready to be hung, Miss G and I had to get a little creative this morning. When raising butterflies in my classroom, I used to hang the chrysalises from the inside of a wooden block that was open on two sides, but without one of those at our disposal, we decided to try and craft one. A box, some packaging tape, and a utility knife later, we had this. As you can see, it certainly ain’t pretty. Buuuut, it gets the job done.
Once the newly-formed chrysalises had been left alone for 12 – 24 hours, we very carefully lifted the lids off of the containers, gently loosening the webbing off of the container walls with a paintbrush if needed. Then we simply created tape rolls using a good strong masking tape, and stuck the lids to the ceiling of our homely box block. This is where they’ll hang now until the final step of their transformation takes place.
As for our other guys who are still busy eating, they all got a good container cleaning and fresh food. Let’s hope this is a welcomed change and not something that harms their ability to begin their transformation.
And while I was busy cutting, hanging, and cleaning, Miss G worked on her own project beside me. When she was done, she brought me her scrap cardboard and explained, “First we have fuzzy yittle caterpillars, and then they build their chrysalises. You wait for a long, long, loooooong time, and they POP out and be butterflies! Then the butterflies will fly, fly, fly away.” She never ceases to amaze me.
It’s day 4 with our caterpillars and look at what we have today! We woke up to find that three of our fuzzy little caterpillars had build their chrysalises over night. We were actually cleaning up from breakfast already when Gracen called out, “Some of the caterpillars built their chrysalises, Mama!”
And thank goodness. If they weren’t pupas today, I was going to go into their containers and do a major clean up. I know that school kits normally say that once the container is closed, leave it closed, and that handling them as little as possible is best, but it can’t be fun to live in your own poop. Besides, from what I read, serious butterfly raisers clean out caterpillar frass daily. For our 5 remaining caterpillars, it’s house cleaning day. Wish me luck!
To start out, I carefully made two large perpendicular cuts on the very bottom of the storage unit in order to open it up. Then, very carefully, I snipped out all of the mesh dividers that created the separate compartments. 
Next, using some picnic table covering plastic (found on large rolls at IKEA and hardware stores), I cut out circles just a hair larger than the circular openings along the sides of the tube. With a hot glue gun and a hand I was wiling to burn repeatedly for the sake of my students and soon-to-be butterflies (just kidding…um… kinda ☺), I glued the plastic windows to the inside of my tube to cover up the holes (gluing them to the outside would have undoubtedly been easier, but that would have also allowed my hot glue slip-ups to be more obvious, which simply was not acceptable at the time). 
In order to create some homey resting ledges for my winged friends, I glued several brightly coloured faux flowers to the inside of the enclosure too. 
In the meantime, since we’re not at the chrysalis stage yet, I pinned up the butterfly enclosure, set our caterpillar containers on the little wooden table, and set up a little reading and observing corner for her to enjoy. 
Now to figure out how we’ll hang our chrysalises… While teaching, I stuck them (still attached to their container lids) to the ceiling of a large wooden block that was open on two sides, but since we don’t have one of those, I’m going to have to get a little creative. We shall see what we come up with!
When I saw that the awesome teachers’ store in our hometown, 
This afternoon the sun was out and I decided to set up something really fun for Grae to explore and experiment with in the backyard.
The set up was pretty simple… Several differently shaped jars and medicine bottles filled with coloured vinegar (we used gel food colouring), a couple of small jars of baking soda, a couple of spoons, and a few empty mixing containers all on a tray. Oh, and some safety goggles. Because in Gracen’s world, science equals goggles. ☺
After helping her with her goggles, Grae set off to work.
As I usually do with this kind of activity, I didn’t give her any instructions. I simply said, “Do you want to play?”
The answer was an excited ‘yes’, and after a few questions about whether or not she could dump/mix/pour things (of course the answer to all was yes), she got started.
While she’s seen the reaction baking soda and vinegar have while 
And she loved it. Mixing a little bit of this with a little bit of that in order to cause colour changes and fizzy foam eruptions was right up her alley.
My little scientist made reaction after reaction, delighting each time she caused foam to spew out of the top of her jar.
One thing that was interesting is how the colour of the vinegar seemed to change with the addition of baking soda. In the case of the orange and the pink, the colours seemed to explode with brightness as the reactions occurred.
With almost all of her baking soda resources used up and her largest jar of vinegar left, we fetched just a little more baking soda from in the house.
It started off slowly, but the reaction did not disappoint. After scrounging leftover baking soda from wherever she could, she managed to create enough fizzing foam to have it flow generously out of the top of the jar. Success!
After our 
Once we cut it in half, she told me that it was ‘veeeeeeery’ seedy, that the seeds could be eaten just like those of the kiwi, and that it felt wet. 
We peeled the skin off and Miss G got straight to the taste test portion of her investigation. The conclusion? It tasted like strawberries (though I think she often uses “strawberries” because she associates them with tasting and smelling good…she also tells me that her toes smell like strawberries!)
It’s amazing how quickly kids pick things up, isn’t it? We’ve only done this once before and she is already using her sense of sight, smell, taste, and touch to make conclusions about a new fruit. I love this little weekly tradition we have going on and I’m excited to see what she chooses next week.
Yesterday, while shopping for fresh produce, Miss G asked if we could take home a starfruit. It got me thinking. I didn’t know if Grae had ever even seen a starfruit, let alone tasted one. I said sure, let her select the one she wanted, and carry it throughout the store for the remainder of our trip.
Today, after nap time, we pulled it out to investigate. We started by smelling it…
Then moved on to running our fingers over it to feel its texture…
And then to gently pinching it to see how soft or hard it was.
When we were done investigating the outside of the fruit, we decided to cut it open.
Of course the first thing Miss G wanted to do was taste it. This particular starfruit was still a little too green, but you can’t investigate a fun new fruit without tasting it!
Starfruit got her seal of approval, and while munching away, Grae was pleased to discover seeds inside the fruit.
This was such a fun and easy little activity that I think I’m going to let Grae choose one new item during our produce shopping trip each week. While we eat a TON of produce, there are still many fruits and veggies we haven’t tried (especially in our local market’s extensive Asian section). It’ll be fun to branch out a little bit and try new things, and I truly believe that when kids are involved in the shopping and cooking aspects of food, they’re much more open-minded about tasting their selections and creations.
I’ve seen 
This afternoon we took out our crate, opened it up, and found all of the materials needed to put together a window garden. Needless to say, my little gardening enthusiast was thrilled.
Included was a clearly laid out instruction card complete with diagrams, and a sweet little observation booklet for Miss G to draw in. 
We carefully set up the garden, referring back to the instruction card after each step. Gracen, Miss ‘Let’s Do a Project!’, loved it and took her work very seriously.
With the exception of really making sure the suction cups were stuck to the window and printing the words “mint” and “basil”, Grae was able to do everything on her own, which was lovely.
We now have a sweet little garden set up right in our living room and I can’t wait to help Grae water it each day and watch as our fresh herbs grow. ☺
Today Miss G and I tried making and playing with the ridiculously fun {and equally messy} substance called Oobleck. It’s made out of only 2 ingredients (or 3 if you want to add a little colour), and it isn’t quite a liquid and it isn’t really a solid… In fact, it behaves like both. 
All you need in order to make Oobleck is water and cornstarch, plus food colouring if you wish.
I like to start by adding the colouring to the water first because it’s a lot easier to stir colouring into water than into the finished Oobleck.
Plus, this way you get to watch the colouring disperse into the water, which is always kind of neat.
Start by giving your water a little stir to make sure the colouring is evenly dispersed.
Then add your cornstarch a cup at a time, stirring it into the water as you go.
When the mixture is nice and thick and you’re not able to pour off any excess water, your Oobleck is ready.
