The Four ways Children Explore the Outdoors

1. Functional Play. Children take in their world with all their senses. Sights, sounds, textures, being able to manipulate and understand objects. Children begin to ask themselves open ended questions, and continuously discover new findings.  
2. Constructive Play. Construction play comes into play when children have already discovered the use of all the toys. Now, they have the opportunity to expand from that; creating more complicated worlds, with blocks, sand/water and sand tools. 
3. Dramatic Play. Children have a wider space to create a more dynamic imaginary world. Out here they can wash, and fill up cars. They can be an ambulance, and save people. They can make "pie" and pour "soup" or "tea".
4. Games with Rules. With the correct given amount of space you can; create large obstacle course, relay races, play hide and seek, or variations of tag games.
