We looked at the Orbis Pictus on-line HERE
Lesson 68 The English Civil Wars
Lesson 69 Robert Boyle: The First Modern Chemist
For this lesson, we did an experiment on acid and alkali.
First, we put water in a jar and dropped a couple of raisins in it. They of course sunk!
Then, we put vinegar in a jar and added some raisins.
we then put baking soda in it and watched.
The raisins started to rise off the bottom of the jar when there were enough air bubbles surrounding them. They float to the top, the bubbles release the carbon dioxide, and then they sink to the bottom of the jar again.
Blessings!!
