The science units in second grade include Animal Life Cycles, Liquids, and Soils. Descriptions of each unit are provided below:
Animal Life Cycles
observe and record the growth and metamorphosis of painted lady
caterpillars. By observing other animals, such as mealworms (beetle
larva) and guppies, students continue to develop the concept of life
cycle in animals.
identify physical properties common to all liquids, examine how some
properties differ among liquids, and develop an understanding of the
ways liquids interact with other liquids and solids.
investigate local soil to discover its different components: sand,
humus, and clay. They test these soil components for characteristic
properties as a scientist would and use the results to explore and
predict the relationship between soil composition and root growth and
