Archive for the ‘Wilberham and Monson Academy’ tag
Wherever you are – anywhere in the world – on June 21st consider taking and submitting a photo of a blank white piece of paper between 5:00 and 8:00 pm.
Your photo will not be just a picture of a pretty white piece of paper, it will be scientific data used to calculate earth’s albedo – the proportion of solar energy that bounces back out to space when it hits the Earth’s surface.
For three years Dr. Kathleen Gorski and her students at Wilbraham and Monson Academy near Springfield, MA have been snapping pictures of white paper and using them to measure albedo by comparing the white paper to the surrounding ground surface.
Now they are opening the project up to anyone who would like to participate!
Here’s how you can get involved:
- Stick a reminder in your calendar for Tuesday June 21, 2011 between 5:00-8:00 pm so that you don’t forget. (Note: I added this step to Kathleen’s instructions because I know I will need a reminder!)
- Put a white card (index or business cards work well) on any ground surface with the white side facing up.
- Snap a digital photo. No particular position for the camera is required. Just hold it, look down, and take the shot. (Kathleen has found that any camera will do – a cell phone or SLR will both work. And any resolution will be fine.)
- Email the photo to email@example.com.
- 5. Include the location (either your city and state or your latitude and longitude).
Kathleen and her students will analyze the data, comparing the response of the white card to the response of the ground surface in each photograph using ImageJ software and will depict the data points on a map. They will be posting the results this summer or fall on a new project website, and Kathleen will be presenting about the project to teachers at the National Science Teachers Association meeting in Hartford, CT in the fall.
