This is the book we have been using for our science labs/experiments. We are now on lesson 12. There are 24 in all, so that means we are halfway there! My boys always love science experiment time. Mom does, too---after I finish getting together all we need. ;)
We have done many experiments on cohesion and/or adhesion. This is our 4th experiment involving capillary action. (Capillary action is driven by cohesion and adhesion.)
|My boys took turns testing 3 different "pathways". A glass dropper, a paper towel and paper. The glass dropper shows capillary action. Do you see the water inside the tube?|
|Testing the capillary pathway of a paper towel.|
|And the paper...|
|Here's my youngest using my hand lens (from my college Botany class!). He is trying to discover why a paper towel has more capillary action. (It has more open space for the water to travel to.)|
|Here's a closer look at the paper towel/paper before they were dipped into the drop of water.|
And a closer look at my old hand lens. It even still has the braided "bracelet" I made from college days on it.
How very granola of me (hehe!).

(Along with an additional, "extra" experiment involving a paper towel and blue food coloring.)
