Outdoor Hour Challenge #39 Weather

This week there has not been a cloud in the sky! Nevertheless, we have completed weather observations three times this week. We have had beautiful clear skies, with temperatures in the low 70's. It has been a great week to be outdoors.

My oldest son has been very glad to be doing a weather challenge. He has rain gauges of various sizes, thermometers, barometers, and wind gauges that he keeps an eye on. He has learned the cloud names and is working on a photographic book of clouds.

As much as we have studied the weather in the past we found the chapter in, The Handbook of Nature Study, on water forms to be wonderful. We loved the way she used the picture of the invisible cap and the "magic" word cold that causes the invisible hat to come off. Her explainations of condensation and evaporation were very visual and we had fun retelling it.

Here is an example of cumulus clouds we made using Amanda's watercolor technique #6 .

Instead of dropping the alcohol onto the paper, we used our cotton swab to shape clouds.
