"Total Eclipse of the Sunspot" - While Mindy, Jet, Sean, and Sydney are trying to use a solar panel to improve their energy efficiency, they notice that Sunspot is acting strange. It turns out that Sunspot was aware of an impending eclipse and was trying to alert the kids to the fact that the Sun would be darkened for a while. Curriculum: A solar eclipse is a type of eclipse that occurs when the Moon passes between the Sun and Earth, and the Moon fully or partially blocks the Sun. In a total eclipse, the disk of the Sun is fully obscured by the Moon. It's important not to look directly at the Sun during an eclipse, but you can watch it through the use of a box viewer. "Sean's Year in Space" - Sean is excited by NASA's "Year in Space" program on the ISS, and decides to try to live for a year in the tree house without ever coming down. The kids keep interrupting him, and finally, after only a short afternoon of trying, he comes down for dinner. Curriculum: The International Space Station, or ISS, is home to several astronauts at a time, who come and go in small capsules like the Soyuz. At this point, astronauts are even staying for a year at a time to study what happens to humans who live in micro-gravity for extended periods, so we can learn what will happen to us on long space voyages, like a trip to Mars.
