Second Grade Science

science_2.jpgThe science units in second grade include Animal Life Cycles, Liquids, and Soils. Descriptions of each unit are provided below:

Animal Life Cycles
Students 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.

Liquids
Students 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.

Soils
Students 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 plant development.
