"Gets Ready, Set, Dough" is the ninth episode of season one of the animated children's series The Magic School Bus. It originally aired on November 5th, 1994.
It's Ms. Frizzle's birthday, and a field trip to the bakery seems perfect, until the bus' shrinkerscope malfunctions. Carlos convinces Ms. Frizzle to continue the trip so she can go to the auto parts shop next door to the bakery. On the way there, the bus shrinks everyone, but Ms. Frizzle continues on to the auto parts shop, leaving the class to learn about baking. They experience chemistry first hand as they try to make a cake when they are tiny, and things get crazy when the bus ends up getting baked inside the cake.
- The TV tie-in book was called "Gets Baked in a Cake."
