Introduction
IIn this lesson second grade students will explore the life cycle of frogs through a series of activities.
Subject: Science
Topic: Life Cycle of a Frog

Standards Addressed
List the California State Standards your lesson addresses. For example:
Second Grade
Science: Life Cycles:   Plants and animals have predictable life cycles.
As a basis for understanding this concept, students know: 
a. organisms reproduce offspring of their own kind. The offspring resemble their parents and each other.
b. the sequential stages of life cycles are different for different animals, for example butterflies, frogs, and mice

 Enabling Activity(ies)
 

  The life cycle and habitat of frogs are examined firsthand in a student built pond that is the focus of frog theme
  in our first grade classrooms. Students become involved in learning about pond components, food chains, and
  the water cycle as they help construct the pond from a child's swimming pool.
  Frog eggs, tadpoles, and frogs may be gathered in the spring from local ponds and streams. Frog eggs may
  also be purchased from a science catalog to coordinate with the beginning of your unit.
  Once the eggs arrive, the growing embryos, then tadpoles are monitored daily in a separate aquarium. Students
  begin observing and recording in frog shaped journals. This frog log is used throughout the study and is
  evaluated for an end of the nit assessment. Vocabulary such as amphibian, embryo, tadpole and life cycle are
  introduced through factual books.
  Construction of the pond is whole class project that involves using actual pond sand, water, plants, and snails.
  Much discussion, rationale and planning evolve as students discover what needs to be put into the pond in
  order for the tadpoles and frogs to survive.
  The food chain is made real as students make sure there is algae and food for the tadpoles, then the frogs.
  Predator/prey relationships in the food chain are also reinforced through simulation games.
  Math skills are practiced in a variety of estimating, measuring, and graphing activities. There are a great number
  of children's books, poems, and songs that can be used to extend the unit into the areas of language arts, music,
  drama and art.
