The leaves in the center (attached to the viny stem) appear to be poison ivy.

Thanks, should I take another picture so it is clearer? I could lay the leaves out

Sheesh. Why wouldn't you photograph it growing - a lot easier to identify, show its habitat and and habit for your putative class project or scavenger hunt.

That's a lot of poison ivy. Either you have a death wish or you're out to get someone.
