The children learned that scientists interact in many ways with objects they want to learn about. This week, the children tasted salt and sugar crystals before observing them through a microscope that magnified the crystals in three dimensions. Only when the crystals were magnified could the children see that the crystals were different shapes and sizes and then compare them to one another. The children were encouraged to use descriptive language to describe what they saw through the stereoscopes. They documented their observations with illustrations, photographs and labels, as scientists often do.
