Analyzing and Predicting

During ramp construction this four-year-old builds a curved path and tries to line it with straight blocks. He includes barriers to cause the marble to change directions as well as keep it from rolling off the flat surface.

Although his theory is partially correct, he must continuously observe his structure and predict which parts will not work. He eventually creates an interesting and functional design. Providing ample time and experience with Ramps and Pathways activities fosters the ability to analyze technological design and predict outcomes.
