How can I resize a model using a script?

I need to change the size of a model, but I don't know how. I tried using setprimarypartCFrame, but I only know how to set position using that. Any help would be appreciated. Thanks!

SetPrimaryPartCFrame only sets the position and should only be used for teleportations and other stuff. I recommend learning about in pairs loops and Part.Size. I'm assuming you're using Workspace for the model, and the script's parent is the model.

local model = script.Parent:GetChildren()

for i, v in pairs(model) do --in pairs loops loop through tables. Use this method as it is more efficient.
	if v:IsA("BasePart") then--This is to check for any parts. If there is an accessory or something like that, it will ignore it.
		v.Size = v.Size * 2
	end
end
