Friday, our Kindergartners mixed food coloring with baking soda. We stirred until the colors blended with the soft, salty soda.
We added a little splash of water, and watched for a reaction. There was none,
so we stirred some more.
Next we added a few squirts of baby lotion. Still no reaction. We stirred some more.
The lotion made our soda solution stick together. We took it out of our cups
and squished and squeezed the dough in our hands and on the table.
It smelled sweet and felt soft.
After we got good and messy, we packed some of our dough into small cups.
Mrs. Douglas opened a jar of vinegar and we smelled the clear liquid.
Some students liked the smell and others did not.
We counted down from 10 and poured cups of vinegar on top of our dough.
It sizzled and fizzled and bubbled and ran right over the edge of our cups, spilling onto the table!!
