Introducing the eye-dropper

We’ve had a busy couple of weeks!  I’m trying to get out of the house as often as possible to avoid tantrums and boredom and laziness on my part! Also, it’s been so hot lately that playing outside just isn’t tolerable for long periods of time.  But, we’ve done some fun activities at home, too. 

I recently purchased a whole bag of eye-droppers.  I wasn’t sure if she would understand how they work—but I thought it was worth a try.  So one day last week, we did some color-mixing activities with them. 

Initially, I filled a tray with red, yellow, and blue, plus some empty slots to do more mixing.

But then I realized that it would probably make more sense if we only used 2 colors to start with (and then later realized that using just plain water would have been a good place to start, too!).  So our next trial run included yellow and blue food coloring.

It was a success!  Yellow + Blue = Green!  She got some good practice using the eye dropper and thought that the changing colors were great!

I made sure to do this activity on a plastic tray, because eventually, I knew she would dump it all out.  I was right.  :)

We have done this several time since, and have used red and yellow to make orange, and red and blue to make purple.  As a bonus, I borrowed the book Mouse Paint from the library and we’ve read that several times too. 

We used the eye-dropper again yesterday for a different science activity—mixing vinegar and baking soda!  It’s very hard to see in the pictures, but when you add vinegar to baking soda, a chemical reaction happens, and it makes great little fizzy bubbles!  I wish I had Ella’s initial reaction on camera—it was priceless!  If I had planned better, I would add some food coloring to the vinegar, just for a little something extra.  ;)

As you can see in this last picture, she’s really getting the hang of squeezing the eye-dropper.  I’m pretty impressed (although quite biased!).  This is a GREAT fine-motor activity, not to mention all the cool science that happens too!
