Jet pitches an idea for the annual Boxwood Terrace Christmas Pageant, and not only is it accepted, he gets to direct it! He casts Sean, Sydney, Mindy, and Sunspot as characters in the play, and hires Mitchell Petersen to help him find this elusive thing called "Christmas Spirit." / Jet is looking for the Spirit of Christmas, something intangible that Sean and Sydney can't quite define. Mitchell wants to belong to the group, but doesn't know how to do it. Both kids get their answer in a heartfelt conclusion.

Comet Fever - The neighborhood is having a star gazing party when Mindy discovers what may be a new comet. While Celery takes Jet, Sean, and Sydney out to space to get a close-up look at the comet, Carrot and Mindy decide to surprise the others and make their very own comet in the backyard using ingredients from home! Curriculum: A comet is an icy body that releases gas or dust. Comets are often compared to dirty snowballs. Occasionally a comet streaks through the inner solar system, creating quite a show! Asteroid Patrol - When Sean learns that asteroids are floating around the solar system (potentially), he decides to set up a homemade asteroid watch-station in the treehouse, and gets all the other kids involved. Eventually, Sean's mother and her colleague at the DSA help Sean and the others understand how scientists monitor the skies for asteroids, a job that Sean doesn't need to do all by himself. Curriculum: Asteroids are mostly found in the Asteroid Belt. Occasionally an asteroid can break away from the gravity of the Asteroid Belt and intersect with the orbit of the Earth. When a small asteroid enters the Earth's atmosphere, it becomes a meteor and burns up.

Jet is amazed to find out that the entire Earth doesn't have the same season at the same time. So he flies with Sydney and Sean from the northern hemisphere to the southern hemisphere to compare and experience holidays in winter and summer...all in one day! Mindy feels bad that she's the smallest kid in the group, so sympathetic Jet and friends use a shrink-ray and become her size. The plan goes awry, and Jet, Sean, Sydney, and Sunspot become the size of mice. Mindy has to follow intricate diagrams to reverse the shrink-ray!

Asteroids, Meteors, and Meteorites - Sean is determined to beat his mystery competitor at a video game of "Astro-Tracker." When Face 9000 tells the kids about the Asteroid Belt, Sean realizes that the best way to learn about asteroids is to see them for himself. Celery flies them out to space, and the kids learn the difference between an asteroid, a meteor, and a meteorite. Worried at first, Sean learns that only the rare asteroid (called a meteorite) makes it all the way to Earth, so he decides that he'll become really good at "Astro-Tracker" to prepare for the future when he can be on a team of scientists who track rogue asteroids. Curriculum: Asteroids are small solar system bodies that orbit the Sun. Asteroids are similar to comets but do not have a visible coma (fuzzy outline and tail) like comets do. A meteor is a small asteroid that burns up as it passes through the Earth's atmosphere. A meteorite is a piece of asteroid that survives falling through the Earth's atmosphere and collides with the Earth's surface. Mindy's Meteorite Stand - When Mindy and Sunspot are digging in the yard, they discover a unique rock that Mindy is convinced is a meteorite. The kids conduct a series of tests to find out and amazingly the rock passes each test. "Meteorite fever" grips the neighborhood, as Mindy sets up a stand so people can see her meteorite, and bring her rocks to assess. In the end, a DSA scientist confirms that Mindy's rock actually isn't a meteor... but, wait, the random rock Mindy's sitting on is! Curriculum: Meteorites are pieces of space rocks (asteroids) that break up when they hit the Earth's atmosphere and fall in small pieces. Meteorites are older than any rock from Earth, and share certain characteristics: density (high), attraction to a magnet, and rust.

When Astronaut Ellen Ochoa comes to visit the DSA and review an engineering project, she runs into the kids, who are running Sean's lemonade stand to raise money for a rocket to Mars. They end up hanging out with her before her DSA meeting. They solve an engineering problem together, which inspires Ellen to use the same solution with the engineering project at the DSA.

When a strange bird lands in Jet's yard, the kids learn it is a migrating Snow Goose who is using Jet's yard as a temporary stopping-off place. Several more Snow Geese arrive, and the kids set up an "observation station" to make notes about their migrating habits. Sean accidentally drops his beloved Neil Armstrong action figure into a large crack in the ground in the woods behind his house. The kids all work together to engineer some kind of robotic arm to reach down into the crack and rescue Neil!

Date Night - When Jet realizes that it's the anniversary of Carrot and Celery's first date, he wants to recreate that first picnic they had on one of Bortron 7's moons. The kids all get involved to help create the perfect date night. Curriculum: It's hard to have a picnic anywhere in the Solar System besides Earth - here we're not too near or too far from the Sun, so the temperature is just right, plus we have liquid oceans and a breathable atmosphre. Anywhere else, you'd definitely have a hard time enjoying a picnic outdoors. Face on the Fritz - When the kids are trying to build a new pet house for Sunspot and FACE 9000 gives them mixed-up directions, they learn that it is time for FACE 9000 to get upgraded. In the meantime FACE 9000's "substitute," the "DATA-BOX," is an old Earth computer from the early 1980s. The kids need to learn how to give instructions in the way computers understand, putting them in charge of using technology in an active way. When FACE 9000 comes back, they have learned to appreciate him, as well as to be more independent thinkers. Curriculum: Technology has advanced greatly since the days of the giant computers that guided man to the moon in 1969. However, even though technology is very useful, it is still a tool, not an end in itself, and people still need to know how to monitor and program it.

Carrot is about to turn 250 Bortronian years old, and the kids have set up a backyard circus to help him celebrate. They all notice that Earth's gravity makes it hard to perform their circus stunts, so they take the whole circus to the Moon, where its 1/6th gravity makes all their stunts much easier! It's Earth Day, and the kids are preparing posters for the big community celebration at the DSA. They decide to research their posters by traveling all around the Earth in Jet's family saucer and observing all the things that make Earth so special.

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.

It's evening at the cul-de-sac, and the kids are looking at two asteroids through Sean's telescope - one is light-colored and one is dark. Meanwhile, Mitchell's dog Cody seems to have run away because he doesn't like the black sweater Mitchell put on him. The kids learn about how, just like asteroids, some things are easier to see in the dark than others, like a white card is easier to see than Cody's black sweater. This amount of brightness is called "albedo." The kids go to their local beach to surf, but notice that the beach looks completely different from the last time they stood there. There's way more sand, and the ocean is far away! They decide to be detectives and study what has happened, and learn that the larger and smaller beach is caused by the tides - the rising and falling of the ocean.

Sean is planning his first sleepout under the stars with his Space Scouts troop, but the weather is threatening, and it looks like his sleepout will be rained out. The kids get help from Mitchell , building a weather observation station to make a weather prediction, and visit the DSA for further help by tracking the weather with satellites. A total eclipse of the Sun is coming to Boxwood Terrace! The kids prepare a Total Eclipse song and dance to perform at the DSA, where the whole town is gathered for the event. Meanwhile, Sunspot attempts to explain the eclipse to all the local animals so they won't think it's night and sleep through it.
