I saw this fun science experiment on Pinterest and knew it would be a great one for Erik. Fine motor skills have always been one of his weakest areas, so anything I can do to challenge him in that area is awesome.
I took some note cards and used white school glue to write the letter A on them. Then, I covered these in salt and (because I didn't actually read the instructions before doing this) left them to dry overnight. The next morning I mixed some food coloring in some water and turned Erik loose with a medicine dropper.recreate this activity and extend the fine motor practice/fun.
At first, Erik just kept squirting the vinegar in the same place, which actually created a fun effect. It took a few minutes before he branched out into the rest of the soda, but when he did he really went for it!
I think both the ideas are ones we'll try again. I want to see what the salt/glue activity does when you actually follow the directions, and Erik would think I was the best mom in the world if I turned him loose with the baking soda and vinegar again!
