Nature games

Goals in the Pool
Spread out across the pool inner tubes or something that could be used as a basket or goal.  Divide the kids into groups and assign each group to an area.

Now hand out a ton of balls and the objective is to make as many goals or baskets as you can in the areas that don't belong to you, and try to keep the other kids from making baskets in yours.

Whoever has made the most goals, and let the least number of balls in, wins.

The Frozen Lake
On the floor you should mark off a big area.  In this area, you should spread out a bunch of hoops, not to entirely fill the space, but leave lots of free spaces.

Tell the kids that the space marked off is a lake with frozen water and that whoever falls in it will be frozen.  The hoops are the only stones they have and, to cross the lake, it is necessary to go stepping across them one at a time.

The kids should cross the lake stone by stone.  The child who falls in the lake must wait until another child comes close to him and gives him a kiss to unfreeze him.

From the River to the Shore
Make a circle on the ground for the kids to put themselves along the line without touching each other.  The inside of the circle is the river and the outside is the shore.

The kids can start inside or outside, but all in the same spot.  The adult will say to the shore and all the kids should jump out of the river, or out of the circle.  If the adult says to the river, they should all jump in the circle.

The adult can give instructions to try to trick the children.  If you make a mistake or take too long, you are eliminated.
