This document contains instructions for several science experiments and activities related to observing animal and plant features, magnetism, and electricity. The experiments involve identifying external features of animals and plants, comparing animal similarities and differences, testing which materials are attracted to magnets, comparing magnet strengths, designing circuits to make bulbs brighter or dimmer, and testing which materials conduct electricity. Students are instructed to make observations, record results in tables, draw circuits, and state conclusions.
