The Scavenger Hunt becomes available after completing Basic Braining, however you won't be able to get many of the items until you have more Psi-Powers.
The Scavenger hunt involves finding 16 items that are hidden around camp. After the first 8 you'll get promoted 4 Ranks, and after the next 8 you'll go up another 4. To receive your rank increases go see Ranger Cruller who is hanging out by the shack in GPC and Wilderness.
You can use this list for checking off items as you find them.

Found near the entrance to the Boathouse and Lake in GPC and Wilderness.
Go to the GPC and Wilderness to the cave-like entrance to the Boathouse and Beach. Head left when looking at the entrance. You'll soon come across the Golden Acorn, but a squirrel will take it and hide in the tree when you get close. Once you have invisibility at rank 30 you'll be able to turn yourself invisible then simply walk over and take the acorn to grab it.
From the campfire area go down the path a ways. Next to the Janitor's house you'll find a whole bunch of rocks. Climb up them to find an area with a burnt out campfire and a large dead tree. You can climb the tree using the levitation ball. Up one branch then up another and you'll find the dinosaur bone.
You can also get here via the ladder above the cave with the mutant bear. Go up the ladder and cross the tight rope to a tree near the Janitor's house then climb up the rocks and tree.
Thanks to swordwoman13 for this!
Found at the Boathouse and beach, after defeating Blueprint Tank.
You'll need to work your way on top of the roof above the area where cotton candy haired kid had been blocking the way. Then climb up as high as possible and jump over to the roof of Cruller's canoe shack. Then by the mountain wall you need to climb up a few different rock ledges to a cave blocked by a panther, the Helmet is in there.
Found in the Main Campgrounds on a platform on a tree.
Near the bottom of the ramp into the lodge is a speaker pole. Climb up it and look away from the lodge, you should be able to see some platforms around trees. One of them has a Psi-Card on it, and on this same one is the Eagles Claw. You'll need to use your levitation ball to jump and float to it.
Found in the Reception Area on a column in the water area.
You'll need to have your levitation ball to get this one. Once you do, go to where the Reception Area connects to the GPC area and look over towards the water and you should see the egg. Jump and float out to grab it.
Found in Sasha Nein's Lab.
Head down the first bend of the stairs and if you look out in front of you, you'll see something glowing, this is the Fossil. There's a section of wall sticking out a bit off to the right, jump up there then you can easily work your way over to where the fossil is located.
At the Isolation Center of the same under the log type bridge thing there is a type of grate and if you use your telekenisis you can get the glass eye.
Thanks to Sarah Peterson for finding the Glass Eye
Found by the Lodge in the Main Campgrounds.
Around the right side of the Lodge there is a picnic table, left of it a small hole in the side of the Lodge and the Doubloon is sitting inside.
Found in the reception area next to the campfire are (the place with the chairs made out of stumps.) If you go up from there you will find some Tombstones. There is a Psi-card there. If you look down the hill you will see a beehive hanging from a tree. Go next to the beehive and jump in the air. This will highlight the hive. Then use your targeting on the beehive and shoot. The beehive will fall and breakopen giving you the fertility idol.
In the Wilderness Area next to the area where the squirrel has the Golden Acorn, you will find two gysers. One is geysing and the other is blocked with the Miner's Skull. You need to stand on the one that is geysing and when it erupts, use your shield. This will force the other to erupt and eject the skull. I'm not sure if you need the upgrade to the reflection shield or not; I already had when I got the skull.
This can be found in the Reception Area back by waterfall.
From the bottom of the waterfall walk away from it on the left side and you'll come to a blue sign and also a rusted truck, the Pipe is right over there.
Found in the GPC and Wilderness area.
Behind the geodesic isolation chamber on top of some rocks. Use the levitation ball to get up there.
Found at the Beach and Lakehouse off main bridge.
When you enter the beach, head down the bridge from the Main Campground or from the GPC area. When you get near the bottom of the bridge where the railing stops head left and you'll find the comic sitting under a pole you can swing on.
Found near the Kid's Cabins in cave.
You can get this after you have Pyrokinesis. Get on top of your Cabin and then use the poles to swing up to the netting on the tree, then jump to the platform and there is a cave you can enter. Go in the cave and you'll slide to the bottom, open the fridge and thaw out (pyro) the block of ice inside, once it's melted you'll find the Turkey Sandwich there!
Found inside the Lodge in Main Campgrounds.
To the right after entering the Lodge there is a table you can jump on, from there you can jump on top of the frame around the door way, then the little pavillion over Cruller's area, then up on the beams. From there you can work your way across the beams to the other side of the lodge where the doll is located.
Found in Thorney Towers after the Milkman Conspiracy.
After the gates open and you can actually go in the grounds, walk up into the first area and get out your levitation ball right by the fountain in the center, jump up and you'll find the Gold Watch floating above the statue.
