Unplugged Challnege - Bottle

Unplugged Challenge - Bottle

LittleA let her creativity run with this past weeks theme. She thought we should take an egg - crack it opne - scramble it (so she can see if she likes to eat it) - then put in some sunflower seeds and cotton - water it and then trim the greenery like hair - and then let it sit on a bottle.

There were many issues with plan A - one of which involves me not being able to cook or eat or smell cooking eggs. Plan B here we come! A few weeks ago I made a basket in our living room that contains all of our activity type books in one place. It is right near a cozy rocking chair. I introduced LittleA to the basket and invited her to curl up near the basket and flip through for some projects any time she would like. We have turned to the basket a couple times already.

One of the books in the basket is the Usborne Big Book of Science Things to Make and Do.

I bought our copy from an Usborne home party so I got to flip through and check it out before purchasing. We have made a couple of the experiments. Most of them are easy and require minimal supplies - or at least things we typically have on hand. The photos are really nice and keep LittleA's attention. She loves to flip through knowing the "theme of the week" and picking a project she feels coordinates. Currently there are a few copies for sale on The book also includes a long list of online resources and links to more science fun.

Ok so book love aside....LittleA choose an experiment - Bubbling Wizard's Brew - that used glass jars (bottles) to hold vinegar, dish soap, food coloring and sparkles...the grand finale was to add the baking soda. I tell ya this still entertains me - so much fun to watch and of course watching LittleA discover a reaction was very fun indeed. I can see why people home school. There is something very powerful in observing someone in the learning process - watching them fall in love with the questions and wonderment that come from it all.

On to our photos and such....

We setup all of our supplies:
  • Book on a book stand. This is really great for experimenting and cooking with LittleA. She can see her instructions or recipes clearly and then they stay out of the splash zone. 
  • Glass Jars: We have a bunch of these that I have saved from recycling. I love using them for storage of craft supplies. Later this spring we will be using them as red lanterns as LittleA is having a Chinese New Year themed birthday party.
  • Food Coloring: For this project I just used the inexpensive set of four you can get in the spice aisle.
  • Dish Soap: any old brand you have on hand.
  • White Vinegar
  • Baking Soda
 Step One:
Fill the jars half way with the white vinegar. I did not have enough to go all the way to the half point so we just made do. 
Step Two:
Add your food coloring. LittleA and I used this as a lesson in color mixing. There are some color recipes on the back of the coloring that show how to make a range of colors by using various drops of each color. This step reminded us of the book Mouse Paint.

Step Three:
Add a generous squeeze of dish soap
Step Four:
Add decorations that you would like to see erupt out the top of the "brew" later. We used silver and blue glitter and some star confetti. I highly recommend the confetti. The pieces were large enough to be seen but still light enough to float on out of the jars on a wave of bubbles.

At this point place your jars onto a cookie sheet or tray if they are not already. This will help with cleanup later.

Step Four
Add a heaping spoonful of baking soda and watch as foaming glittery colored brew comes spewing over the tops of your jars.

Was glad we put a cookie sheet under our glasses...what a mess that would have made off the counter onto the floor. It was neat to see the swirls of foam colors on the tray when it was all done.
Then to top it all off LittleA had a ball rewashing all the jars and having some water time in the sink. 
Even though I am late posting this...head on over to Unplug Your Kids and see how the other families participated this week. And join us next week for the theme HAPPY.

I love that last photo. Action shot!

That looks like fun. I think I am going to have to get that book!

Michie said...

That looks like so much fun! I like the idea of using the book stand to prop up the book. How old is your little one? I'm wondering if this book would be good for us too.

That looks cool. Might try it with Cali tomorrow since we will be stuck at home; sick again! :(

This is a nice variation of the soda/vinegar combo, which we do a lot. Somehow it never gets boring!

We've got that book too - I love Usbourne books! Unlike the project we chose to do this week, at least vinegar and bicarb never fail to impress!
