Mindy Pet-sits Sunspot - Sean, Sydney, Jet, and Carrot head out to view the Northern Lights. Mindy, upset she can't go, gets a boost - Sunspot stays back and agrees to let her be his pet-sitter. As the group in the saucer searches for, yet can't find, the Northern Lights, Sunspot and Mindy work on a backyard project - making their own amazing backyard 'Northern Lights' display! Curriculum: Northern lights (aka, aurora borealis) are a natural, awesome phenomenon. The origin of the aurora begins when a cloud of gas is ejected from the Sun's surface. When it collides in Earth's atmosphere with oxygen and nitrogen, it produces dazzling auroral light. Treehouse ISS - When the kids realize that they all want to use the treehouse at the same time for different activities, arguments break out. Mindy tries to help by creating a schedule for each kid to use the treehouse alone. In the end, the kids realize they need each other's company and ideas in order to be successful in their own projects. In resolving their problem, the kids learn to think like the scientists on the International Space Station, who have to find a solution to the problem of getting along while doing different projects in a small space. Curriculum: The International Space Station (ISS) program is a great global human achievement in international cooperation. Countries work in partnership to support the experiments of scientists on the ISS, including observing space, growing plants in micro-gravity, and recording observations.
