How do you save multiple values before they are changed?

So I want to make a script that saves a part's position, transparency, and size, then tweens the parts to its position, transparency, and size that were originally saved. In other words, it builds the model. Any help? This is what I have so far:

for index, child in pairs(workspace.ItemQ:GetChildren()) do
	child.Size = Vector3.new(0,0,0)
	child.Position = workspace.QPos.Position
	child.Transparency = 1
end

wait(5)

for index, child in pairs(workspace.ItemQ:GetChildren()) do
	local TweenService = game:GetService("TweenService")
	local Part = child
	local info = TweenInfo.new(
		1,
		Enum.EasingStyle.Quint,
		Enum.EasingDirection.Out,
		0,
		false,
		0
	)
		
	local Goals = 
	{
		Size = child.Size;
		Transparency = child.Transparency;
		Position = child.Position
	}
		
	local Tween = TweenService:Create(Part,info,Goals)
	Tween:Play()
	print("Brick placed")
	wait (0.1)
end
