Our first graders have begun a space exploration unit in the Discovery Lab. To begin our study, we looked at images produced by NASA satellites and telescopes of various places and objects on our planet and in our solar system. To do this, we used 3D glasses to view a slide show NASA has put online. (The link is: www.nasa.gov/externalflash/3-d-200705) We also read a book called, The Big, Blue Marble….and from reading it, we now can see why our planet can be called that!
The Big, Blue Marble..Our Earth
We also created a birds eye model of our sun in comparision to the Earth. By making a ‘human compass’ and using our estimation skills, we were able to gather that the Sun is a lot bigger than the Earth, and even though it is 93,000,000 miles away from our planet, its light travels pretty fast for that distance…it takes about 8 minutes for sunlight to reach the Earth from the Sun! We thought that was pretty amazing for such a great distance to travel! The sun must really have a lot of power to do that!
In our next visit to the Discovery lab, students will be able to chat with NASA reserachers and experts relating to our Moon. Through our videoconference system, we have set up dates in which our first graders will interact with NASA Glenn Research Center to learn more about our Moon, as well as other aspects about space. This is our prelude to our upcoming NASA Discovery Celebration coming up next month–February 25, 2010!
