Core Skills Analysis
Science
Pat froze water in zip‑lock bags, some tinted with food colouring, and observed the formation of solid ice blocks. He then smashed and scooped the ice, noting how it changed shape and texture when force was applied. Pat watched the ice melt over time, recognizing that heat caused the solid to become liquid. Through this hands‑on activity Pat learned about states of matter, the effect of temperature on matter, and basic observations of physical change.
Tips
Encourage Pat to record his observations in a simple science journal, drawing the ice before and after melting. Set up a comparison experiment by adding salt to some ice bags and noting how the melting rate differs, introducing concepts of freezing point depression. Explore the colour mixing that occurs when two coloured ice pieces melt together, linking to basic colour theory. Finally, connect the observations to everyday examples, such as why snow melts on a warm sidewalk, to deepen real‑world relevance.
