Change is good for everyone except Arnold, who's worried that a new teacher - Ms. Frizzle's young sister - will alter the class's "ecosystem".

An out-of-this world class trip takes the students up into space, where a selfie-obsessed Keesha accidentally sparks disaster.

An icy glacier's eye-opening birth story helps a data-driven DA -- who's not one for public speaking -- deliver a talk to a sold-out crowd.

A skittish Arnold looks to alternative energy sources to help keep his fears at bay while camping outdoors with Ms. Frizzle and the class.

Ms. Frizzle turns the Magic School Bus into a submarine to take the class into the ocean's darkest depths and retrieve Jyoti's high-tech locket.

When the class gets an invite to compete on Tim's favorite TV game show, the bus takes them all back in time to bone up on how fossils are formed.

From scratch marks to stolen pepperoni slices, the science classroom's a mess -- and all clues seem to point to Wanda's bird friend, Marty the Magpie.

Wanda's been so busy planning this year's Fall Fun Feast that she forgot about the food. Now her only hope is a farm that's supposedly haunted. Gulp!

While building (and rebuilding) their own space rover to tackle the terrain on a faraway planet, Jyoti and the class learn that it's OK to fail.

A race between competitive brothers Carlos and Mikey takes the gang to the top of an in-pasta-ble mountain, where they learn about simple machines.

Every person and animal poops. But the class isn't convinced that this so-called "brown gold" is as valuable as DA's famous inventor uncle says it is.

The bus takes Ms. Frizzle and the class deep inside Arnold's cousin Janet to learn why our genes makes us look, act and feel the way we do.
