Described is a science activity for intermediate grades which uses science skills to solve a mystery. Fingerprints, footprints, chromatography, invisible ink, and microscopic analysis are used in the activity. Observation, data analysis, and deductive reasoning are stressed. (CW)

Describes a fourth-grade unit on density which introduces a concept useful in the study of chemistry and procedures appropriate to the chemistry laboratory. The hands-on activities, which use simple equipment and household substances, are at the level of thinking Piaget describes as concrete operational. (BC)

Outlines steps for involving problem students in discovery-oriented science activities. States that planning is the basis for an effective lesson. (RT)

Garlic is an ideal plant for the elementary classroom. It grows rapidly in water without aeration for several weeks and remains relatively free of microbial contamination. Simple experiments with garlic purchased at grocery stores can illustrate various aspects of plant growth. (PR)
