[size=100]It's Thursday - the kids are bouncing off the wall because break starts tomorrow afternoon.
If you are looking for a way to engage them, please consider participating in my, and my students, Albedo Project.

Participating in the Albedo Project is as simple as taking a digital picture!

1. Put a matte white card or paper on a outdoor, ground surface (or formerly grassy surface). The white surface should fill 1/4 to 1/2 of the total view.
2. Do not cast a shadow on the image.
3. Snap a digital photo. No flash.
**NOTE: we do need to be concerned about overexposure. Use auto adjust for exposure (if you have an EV setting, -1 is good; if you have an ISO setting, 100 is good, avoiding your own or other strong shadows in the photo will also help).
4. Email the photo to albedo.project@gmail.com
Include the location** (either city/state or lat/long if the photo is not geotagged)

Participate, and invite your friends!

Many people know that the winter solstice marks the day when winter officially stars in the Northern Hemisphere, and when days will start to become incrementally longer. But what exactly is going on?"

Thank you for considering!

Awesome Kathy,

Wish I would have read this post prior to our Winter Break. I most certainly will note the site you highlighted and hopefully my scholars can participate in the event next year.

Thanks for sharing,

Not a problem - we do these during the solstice and equinox, so 4x per year. There's nothing special about those days - just that they help with a hook. The next iteration of our project will be to invite groups that have their own localized maps to submit either their photos or maps to be included.
Thanks for considering!!
