School would be ruined for these kids because of Ms Frizzle. Hell, life would probably be ruined. Imagine getting to go on all these amazing, magical adventures, and then after the year's up it all ends. You move onto your next grade and go back to boring regular school, knowing the whole time that Ms Frizzle's new class are going into space and the bottom of the ocean and stuff. Then you grow up, and whether you get an office job or become something amazing like an astronaught none of it will compare to that year you spent in Ms Frizzle's class. You'll do all you can to relive that life you had, but you'll never have a magic bus of your own. You'll waste your life trying to find one, and at the end of it all you're just a sad old person alone with memories of your once perfect childhood.
