Water Cycle Science With A (healthy!) Snack!

As we were driving yesterday, Annabelle pointed out the clouds, and predicted that it was going to rain. I took advantage of this teachable moment, and asked her a series of questions:
Why do you think it's going to rain?
What do those clouds look like?
What's in those clouds?
What happens when it rains?
We talked about the different types of clouds, and how they formed.
Then I got to thinking. A few searches around the internet directed me to two fun science experiments to help better explain the water cycle.
The first experiment involved a jar, water, food coloring, medicine dropper, and some Barbasol shaving cream.
We filled the jar about 2/3 with water, and topped it with shaving cream.
It looked just like a puffy cumulus cloud!
Next, I filled a bowl with a little water and blue food coloring.
The girls had a great time squeezing and dripping the colored water onto the shaving cream cloud.
We did learn that I used too much shaving cream, as it took the colored water a long time to make its way down to the bottom of the cloud to "rain" into the jar.
Once I scraped a heap of shaving cream off the top of the jar, things started moving more quickly.
The girls were astonished when the shaving cream clouds filled with blue water, and began to "rain" down.
Next, we made a real cloud in a jar.
I explained that the sun warms the water on the ground, and it evaporates into the sky, where it's colder.
We filled this jar about 1/3 of the way with hot water. I also took advantage of this opportunity to make myself a cup of tea! Food coloring is optional here, but it makes it easier to see what's happening, and adds an element of fun for the kids.
A slightly larger bowl of ice was added to the top, and we waited and watched.
Talking about what we learned about the water cycle, I asked Annabelle what she thought would happen. What do you think will happen to the bottom of the bowl? She predicted that it would be wet, and she was right!
After some time, the water collected at the bottom of the bowl (condensation), and it rained down onto the table.
That moment. The moment when I could tell that Annabelle had truly learned something, about how clouds are formed. She made a cloud! And she made it rain!
After all that excitement, it was time for a snack.
Greek yogurt served as our cumulus clouds, and blueberries served as the rain drops.
We always love finding snacks that are fun AND healthy.
Both girls had a good time making (and eating) rain clouds.

Messy Monday: Pumpkin Playdoh

Autumn has arrived. And I couldn't be happier.
Last Tuesday was the first full day of my favorite season. The air was perfectly crisp, as I dressed the girls in long sleeves, and put a hat on Hazel to venture out for our daily walk around the neighborhood. They looked precious, all bundled up and warm. Trees were beginning to become dotted with bursts of yellow and orange.
But one of the best parts of Autumn is pumpkin spice everything.
So when I found this recipe for pumpkin spice playdough, I just had to share my love with Annabelle.
After our walk, Hazel was ready for a nap. Perfect time for some Mommy and Annabelle bonding and learning.
While this recipe was simple, it still took a great deal of parental supervision and assistance, as you need to use a stove.
I measured out the ingredients, and placed them in individual containers, so she could enjoy dumping each item into the pot before mixing it together. (I added a little vanilla extract to the water, to give it a little yummier smell.)
I was surprised that she mixed it for as long as she did before needing my help.
I'll admit, by the time the mixture came together, my arm was feeling a little sore.
Start to finish, I'd say it took about 10 or 15 minutes.
We waited a few more minutes before the dough was cool enough to touch, and I added a few drops of orange food coloring, and kneaded it to distribute the color.
I love that the cinnamon and nutmeg left flecks of brown in the dough to give it a more natural look to it.
Annabelle liked that the dough was still warm when I gave it to her. She had a great time making a family of little pumpkins.
It was so perfectly soft, and so much nicer than store-bought play-doh, It even cleaned up more easily.
When we were done playing (about an hour later), I placed the ball into a Ziploc bag, squeezed all the air out, and zipped it shut. We pulled it out again a few days later, and it was still very soft and pliable.

This recipe is a great base recipe, and I plan on making peppermint playdoh in December with red dye.
Try different scents and colors.
You can also add glitter for an extra shimmer.

Messy Monday: Slime With A Twist

Having a child with eczema makes sensory play a bit of a challenge. But when that child loves sensory play, you make it happen.
Having made slime (corn starch and water) a few times already, I wanted to give it a little twist this time. After a quick search for "eczema friendly sensory play", I found Interaction Imagination. Her method used lotion and corn starch, but suggested trying coconut oil.
Coconut oil? We love coconut oil!
Here is what you will need:
I melted small Dixie cups of coconut oil, and added a few drops of green food coloring. I wish I had thought ahead, and had Annabelle help with this step. Being water-based, the food coloring did not mix with the oil. Instead, it bubbled, as it sank to the bottom of the cup. A quick stir with a chopstick broke up the bubbles into several tiny specks of green, floating in the oil. What fun that would have been with multiple colors in a clear cup and a flashlight.
I then placed the cups in the refrigerator to quickly solidify the oil. I was hoping this would enhance the sensory experience. While we waited, an impromptu game of balloon baseball with a hair brush broke out in the living room.
Annabelle especially loved trying to catch the balloon, while I kept whacking it with the hairbrush, out of her reach. She did correct me at one point, however. Apparently, you are only supposed to hit the balloon with the bristles.
Hazel enjoyed the show, too. She got excited whenever the balloon floated close to her.
Before long, the coconut oil was solidified, and ready.
Just like the baking soda experiment, I started by giving Annabelle one component of the activity at a time. She played with the corn starch like it was snow, scooping, scraping, and sculpting to the best of her ability.
After about 10 minutes, I added the oil. If I were to do this activity again, I would have left the oil at room temperature, so that it would be a solid state, but not so hard. She struggled to get the oil out of the cup and melt it with her hands. This caused her to lose some interest in the block of oil, until I helped her by squeezing it between my fingers.
Once that was done, though, her mess was under way. The highlight of the activity, was when she discovered she could make farting noises by squeezing the mixture between her palms. She giggled as the goop oozed between her fingers, and the fart noises abounded.

She played for about an hour, covering her arms and face in corn starch and coconut oil. Clean-up took about 10 minutes (not including getting herself cleaned up, which wound up being a quick bath).

Let's Get Messy!

This morning, the weather was indecisive. One second, the clouds began to form an ominous cover over the sun; and the next second, the sun prevailed, and brightened up the whole sky. I decided not to risk it, and skip the pool today. I have been watching a friend's kid this week, so it's been 3 against 1 since Monday (with a sleepover last night). Getting all three girls fed, pottied (or diapered), sunscreened, and suited up for swimming takes nearly 30 minutes from start to finish. I was not about to risk a full-out melt-down from Annabelle over not being able to go swimming because the weather decided to rear its ugly head, and rain on our parade at the last minute.
Instead of swimming, we spent time in the air conditioning, making a huge mess of the dining room. And it was FUN! I recently bought a huge bag of baking soda for $3 at BJ's, so I knew that I had plenty of that on hand. I searched for activities to do with baking soda, and found some very fun ideas. Armed with my supplies, I got to work setting up for Annabelle and her friend, Bella. Set-up was a breeze, and I was ready for them within five minutes.

For each kid you will need:
Jelly roll pan for your work area
Desired amount of baking soda (if I had to guess, I'd say I used about 1/2 cup for each girl)
Plastic utensils
Vinegar
Food coloring (optional, but extra fun)
Dixie cups for each color desired
Pipette, straw, or eye dropper
An art smock (I used my old t-shirts)

I started off by letting the girls explore with the baking soda in the pan. They used a fork to draw patterns and designs, and tried to ball the fine powder up like snow balls. When they started showing signs of losing interest, I introduced the next part of the activity.
 

I gave them each three Dixie cups with a few drops of food coloring, and filled half-way with vinegar. In hindsight, I used way too much food coloring. Annabelle is currently sporting bright purple hands. Oops! Next, I demonstrated how to use a straw to drip the vinegar over the baking soda.

Then Annabelle got creative. Instead of dripping the vinegar onto the baking soda, she took a fistful of baking soda, and dumped it into a cup of vinegar. She was thrilled with her discovery.
 
The next hour was spent stirring, pouring, and smearing the mixtures. While the jelly roll pans contained most of the mess, I still had my work cut out for me.
But it was worth it.

I loved allowing Annabelle to be a little scientist, and make her own discoveries and observations. When we do activities like this, I give her ideas and suggestions, but allow her to control the situation. What if I had stopped her from dumping the fistful of baking soda into the vinegar because that's just not what we're doing right now? What if I had decided that food coloring was too messy? What if I had decided the whole activity was too messy? She would have missed out on so much fun and discovery.

Don't be afraid to get messy. Kids are washable. Clothes are replaceable. You only get one chance at today, so make memories of fun and exploration.
Oh, and it never rained.
