1. Exploring Physical Properties of
Dry Sand, Wet Sand, and Sand
Play-dough through Play and
Tool Use

2. Beginnings…
 Plan: Build with
blocks and
observe/test
strategies for creating
stable structures
 Purpose: Explore the
concept of
foundations and
bases and the role
they play in making
stable, secure
constructions

3. …Later that Day
 Technology on the
playground: Sandbox
 Tool use
 Construction
 Exploring of materials

4. Redirection
 New Plan:
 Explore construction techniques and purpose/use of
tools through a variation of the same material (dry
sand, wet sand, sand play-dough, oobleck)
 Observe similarities and differences in the way
children approach the differing materials and how it
influences their construction strategies, the way they
utilize tools, and in which ways they explore the
material
 Learning outcomes:
 Discover and explore the properties of varied
materials
 How to adapt and expand schemas and strategies to
effectively and satisfactorily work with a new material

5. Dry Sand
 Sifting
 Raking, molding
 Use of Shovels
 Digging
 Filling buckets, sifters, etc.
 Pouring
 Use of construction trucks to transport sand
 Symbolic play

6. Water and Sand
 Tool use:
 Watering pail
 Hands
 Shovel and Buckets
 Construction:
 Molding
 Making impressions
 Mixing (all more effective with wet sand)
 Exploring material:
 Where did all the water go?
 More heavy (harder to pick up full bucket)
 Feels different; a lot more exploring material with hands compared to dry sand
(swishing in puddle, scooping wet sand, squeezing in hands, letting it drip)
 Can’t pour as easily as dry sand
 Less symbolic representation and play
 Hesitant to interact at first

7. Water and Sand

8. Sand Play-dough
 Construction:
 Similar to play-dough (rolling balls/snakes, pancakes)
 Tools:
 Hands
 Exploring material:
 Rolling
 Squeezing in hands
 Flattening
 Crumbling in fingers
 Symbolic representation

9. Sand Play-dough

10. Sand Play-dough

11. Self-Initiation
 A rainy day on the playground…
 Filling up buckets using shovels, with water from
puddles
 Little symbolic representation
 Transporting filled buckets to sandbox
 In the sandbox:
 Symbolic play (unlike first interaction with sand
and water)
 Wet sand becomes incorporated with dry sand
 Wet sand for molding, dry sand for pouring etc.
 Combining varying amounts of water and sand to
create a variety of textures

12. Observations
 More explorative with unfamiliar materials
 More purposeful, higher level of symbolic
representation with familiar materials
 Discovered new strategies/purposes to initiate
and utilize in future situations
 Using wet sand for molding
 Using dry sand for pouring or transport

13. Next Steps…
 Gardening; Cooking
 Apply similar materials
and tools in real-life
context
 Representational play
mostly revolves around
baking and cooking
 Explore and incorporate
more tools and more
materials, their purposes,
how they interplay, and
the results they create
 Connect symbolic
(sandbox) experiences to
real-life (cooking)
counterpart
