Use the senses to investigate and make comparisons (e.g., compare textures of objects using the sense of touch).
Investigate simple cause and effect or other scientific principles such as magnetism and gravity through play activities (e.g., observe that a toy car rolls slower when a ramp is lowered or that block towers consistently fall downward).
With teacher assistance, conduct an investigation, predicting and testing results (e.g., mixing colors into cup of water, predicting changes with each new color added, then testing results).
