(at around 12 mins) While the Frankenstein family is having fondue, the fondue sticks appear and disappear from the pot.

(at around 20 mins) When Victor went back to the Pet Cemetery to retrieve Sparky to bring him back to life, you see some flowers on top of where Sparky was buried. In the next scene, when Victor starts digging, the flowers moved to the side with no indication of Victor bending over to move them.

(at around 6 mins) During the classroom scene when Mr. Rzykruski is explaining the mechanics of lightning, his diagram shows positively charged clouds above the ground, which is shown as being negatively charged by electrons. The diagram should contain negatively charged clouds (containing a surplus of negatively charged electrons) over the ground which should not have any charge.
