After students view the first picture from the Explorer VI Satellite, they discuss the differences between this first image and the images of the earth that we typically see today.
The first picture of Earth was taken by the U.S. satellite Explorer VI in 1959.
The prototype for the World Wide Web was created in 1990.
Students look at pictures from the past using the WayBack Machine and brainstorm a few websites to explore to think about how they have changed over the years.
