List of The Magic School Bus episodes

This is a list of episodes of the children's television series The Magic School Bus, which is based on the books of the same name by Joanna Cole.

It cuts down the forest, and turns recycling trucks into garbage trucks. The kids are confused when it turns the swing set in the park into aluminum cans and such. Wanda is still pleased, since if recycling hadn't been invented, then her soldier would be still waiting for them in school. However the bus turns the school into a garbage dump when they get there. Finally, the bus un-recycles itself. Wanda then apologized that she ever wanted to get rid of recycling, and wants it back. The Friz changes the bus so it changes everything back. Wanda makes new toy soldiers from the melted plastic pellets. Arnold has to leave for his sick grandma for Hanukkah. Soon, Arnold's classmates, Ms. Frizzle and Murph appear.

However, Keesha refuses to put in her dollar, as her grandmother was once duped by a similar organization (the Home Mopping Network.) Therefore Ms. Frizzle takes the class on field trip to see the three stars being sold by Horace Scope for themselves.
47	"Gains Weight"	Gravity		George Arthur Bloom	November 1, 1997 (1997-11-01)
Phoebe has been chosen to do a slam dunk for the whole school. How can she do that? She's not tall enough. She reasons that maybe if she just knew how it felt, then maybe she could do it. Therefore, Ms. Frizzle takes the class into outer space and transforms the school bus into a planet with adjustable gravity. With little gravity, Phoebe finds a slam dunk easy, but with no gravity it is impossible to even make the ball go through the basket. However, when the lever accidentally falls into the position of heavy gravity the class has trouble even standing up. They'll have to get the gravity back to normal in order to return to Earth in time for Phoebe's performance.
48	"Makes a Stink"	Smell		George Arthur Bloom	November 8, 1997 (1997-11-08)
Flora Whiff (Bebe Neuwirth), the famous expert on smell — whose "nose knows" — comes to school to judge the First Annual Smell Search. Ms. Frizzle's class creates a unique smell which is bound to take first prize, but Arnold's cousin, Janet (from Gets Lost in Space, Butterfly And The Bog Beast, Gets A Bright Idea, Works Out, and Gets Swamped), determined to win by herself, changes their smell to an odor only a skunk could love. The kids discover the secret to what makes things smell... now they have to make sure their creation doesn't make a big stink. Michael makes a cameo, since he did not appear with Ms. Frizzle and her class.
49	"Gets Charged"	Electricity		Suzanne Bolch, George Arthur Bloom, Jocelyn Stevenson	November 15, 1997 (1997-11-15)
It's Valentine's Day, and the class is selling light bulbs as a fundraiser. They decide to go to Ms. Frizzle's house to see if she'd like to buy some, but her doorbell isn't working. Tim and Wanda go to find her, and they overhear her reading a "love letter". The class now has to fix the doorbell before Ms. Frizzle's "big connection" comes over.
50	"Gets Programmed"	Computers		John May, Ronnie Krauss	November 22, 1997 (1997-11-22)
Mr. Rhule, the principal, gets a new computer, and it's Ms. Frizzle's class' job to open up the school and set up his computer. Carlos's brother, Mikey (from Getting Energized), is a computer expert. After he sets the computer up to raise the flag, make the coffee in the teachers' lounge and ring the bell, he goes on his own trip to see the inner workings of the computer. Carlos records his voice with a handheld microphone. As usual, something goes wrong (along with the replay of his recorded voice), and Mikey has set the computer to do the tasks every minute instead of everyday. Can the class get to Mikey to have him fix the problem?
51	"In the City"	Cities		Noel MacNeal, George Arthur Bloom, Jocelyn Stevenson	November 29, 1997 (1997-11-29)
On the class' first "normal" field trip to the zoo, they wonder how the animals could live in the city. Ms. Frizzle then turns the kids into various city animals (Tim, Arnold, and Phoebe into foxes; Ralphie, Wanda, and Keesha into possums; Dorothy Ann and Carlos into peregrine falcons, and Ms. Frizzle a raccoon), but the bus thinks it's a bear, and with Liz inside, leaves the class. Worse, the city authorities are after the bus, thinking that it is a lost animal needing to return home. Will the class make it to the bus in time, or will they be animals forever?
52	"Takes a Dive"	Coral reefs/Symbiosis		Jocelyn Stevenson	December 6, 1997 (1997-12-06)
The series finale. For their coral reef projects, the class each worked in partners. Wanda hates partnership, and instead of working with her partner, Dorothy Ann, Wanda does her own project. Ms. Frizzle tells the class about her great-great-great-great-great-great-great-great-grandfather, Redbeard the Pirate leaving treasure in a coral reef, and Wanda, a wannabe pirate, is for looking for it. Ms. Frizzle tells them to go two-by-two with their partners, which Wanda teams up with Dorothy Ann, Keesha teams up with Ralphie, Tim teams up with Carlos, and Arnold teams up with Phoebe. At first, Wanda didn't like that, but they learn about ocean partnerships, such as hermit crabs and sea anemones, snapping shrimp and gobie fish, sharks and remoras, etc. However, they are forced to work together when one part of the reef has been bleached out by none other than the treasure chest. They then go back to school, and open up the treasure chest, which has a portrait of Redbeard, and a model of the ship.
