Gas Experiments

On Wedenesday, we did a few experiments with gases.  One experiment involved mixing vinegar with baking soda.

The result is always fun to watch.  Ask your child what happened.

We started this experiment at the beginning of the week.  We mixed water, salt, and food coloring together.  We are watching as the water slowly evaporates and turns into a gas.  We hVe made a number of hypotheses over what will happen to the salt. 

Now that we have had a 5 day weekend, I wonder what the container looks like now.
