Help! First day and I have zero info from school

Hi, I am scheduled to take over 5th grade science classes on Monday the 10th feb.
I know nothing of these classes And despite a serious of questions and an acknowledgment of how I feel walking into a class ‘cold’ I have had no responses. Therefore I can’t prep as I don’t have anything other than a video on the human body.
Conning in mid year is horrible because I’ve done it before.
I don’t even know what my room looks like and feel like I’m just being thrown to the wolves and won’t be necessary next term.
Any advice??
