Learn Italian: Aiutami a scolare gli spaghetti, che la pentola è pesante! - Help me drain the spaghetti, because the pot is heavy!

This is an example of the informal causal che. In spoken Italian, che is often used to justify a command or statement you just made, essentially meaning "because" or "since". While you could grammatically use perché, using che sounds much more natural, urgent, and conversational after an imperative like aiutami.

Why do we need the preposition a between aiutami and scolare?

The verb aiutare requires the preposition a when it is followed by an infinitive verb. Even though the pronoun mi is attached to the end of the command (aiuta + mi), the grammatical structure remains aiutare qualcuno a fare qualcosa (to help someone do something).

Can scolare be used for draining any kind of liquid?

Scolare is primarily used in cooking and daily chores to mean draining a liquid from a solid, usually with a strainer or colander (lo scolapasta). You will use it for pasta, vegetables, or drying washed dishes. For draining a flooded area or a medical wound, you would use a different verb like drenare or prosciugare.
