Wanda is going to see The Nutcracker and is bringing a toy soldier instead of taking money, as they are taking toys to give to homeless children. As usual, something goes wrong. Arnold mistakes the soldier for something being taken to the recycling plant and Wanda's soldier is turned into plastic pellets. Wanda angrily declares she wishes recycling had never been invented. Naturally, this gives the Friz an idea. She turn the bus into an anti-recycling machine, which changes the city to the way it would be without recycling. 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 had never 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 apologizes for having 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. This episode aired as a special one-hour episode during its original airing. The first 30 minutes is the regular episode and the second half of the hour is a behind the scenes look of the series with the voice cast. For subsequent reruns, it aired as a regular 30 minute episode with the behind the scenes segment cut out. The home video release is also missing the behind the scenes segment and only features the 30 minute version seen in syndication.

46	407	"Sees Stars"	Stars	Lawrence Jacobs	Noel MacNeal	Dabney Coleman	October 25, 1997
On Dorothy Ann's birthday, she has, unfortunately, been taken sick and has to stay home. The class does not know what to get D.A. as a present until they see Horace Scope (Dabney Coleman) on S.S.N., the "Star Shopping Network," who is selling the stars for seven dollars each. Tim reasons that if every student puts in a dollar, they will be able to buy Dorothy Ann a star and name it after her. 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. This episode takes aim at the Home Shopping Network and the Quality, Value, And Convenience network.
47	408	"Gains Weight"	Gravity	Lawrence Jacobs	George Arthur Bloom	Paul Winfield	November 1, 1997
Phoebe has been chosen to do a slam dunk for the whole school. But how can she, not being 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 will have to restore the gravity to normal so they can return to Earth in time for Phoebe's performance.
48	409	"Makes a Stink"	Smell	Lawrence Jacobs	George Arthur Bloom	Bebe Neuwirth	November 8, 1997
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, determined to win by herself, evilly corrupts their smell to a stench that even a skunk would hate. The kids discover the secret to what makes things smell...now they have to make sure their creation will not make a big stink. Michael makes a cameo, since he did not appear with Ms. Frizzle and her class. There is a big mistake in which Ralphie is talking using the voice of Arnold right after they get out of the trash.
49	410	"Gets Charged"	Electricity	Lawrence Jacobs	Suzanne Bolch, George Arthur Bloom, Jocelyn Stevenson	N/A	November 15, 1997
On Valentine's Day, the class is selling light bulbs as a fundraiser. They decide to go to Ms. Frizzle's house to see if she wants to buy some, but her doorbell is not 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	411	"Gets Programmed"	Computers	Lawrence Jacobs	John May, Ronnie Krauss	Malcolm McDowell, Paul Winfield	November 22, 1997
Mr. Rhule, the principal, gets a new computer, and Ms. Frizzle's class has the job of opening 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's 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	412	"In the City"	Urban wildlife	Lawrence Jacobs	Noel MacNeal, George Arthur Bloom, Jocelyn Stevenson	N/A	November 29, 1997
On the class's 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 mistakes itself for 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	413	"Takes a Dive"	Symbiosis	Lawrence Jacobs	Jocelyn Stevenson	N/A	December 6, 1997
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. They learn about mutualistic, symbiotic relationships in coral reefs , 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 that can change shape much like the bus.
