Something else to look for during the eclipse, whether you are in totality or not: Pay attention to the shadows on the ground or sides of buildings. Two things occur, yet are easy to miss.

First, at some point during the partial eclipse, you should be able to see little crescents on the ground in the shadows under trees. Depending on the tree and the conditions you might see hundreds if not thousands of crescents, and if there is a breeze, they will "dance." It is really cool to see.

Second, as the eclipse approaches totality, or the greatest extent of obscuration, pay attention to shadow boundaries, especially the one your body casts. Make certain you note your shadow before it starts, and as obscuration increases. To begin with the edge will be diffuse and rather soft. This is because the sun is a relatively large light source. As more and more of the sun is obscured by the moon, the edge of your shadow will become more and more sharp. This is due to the light from the sun being narrowed to a smaller and smaller "point." Just before totality, the shadow edge will be exceptionally "crisp."

Both of these effects are easy to and worth photographing. Dancing crescents should make a nice short video.

Below is a cell phone photo of a photo I took in Turkey. My daughter's science project that year was to measure the temperature change from start to finish over the course of almost 4 hours. The temperature never fully recovered after totality.
