Frog Day

Objective:
The students will sequence a frog changing from a tadpole into a frog.

Materials

• A book or a web site which explains the life cycle of a frog.  Good ones to use are The Frog Page, Frogs Of New England, From Tadpole to Frog (Let's-Read-and-Find-Out-Science) by Wendy Pfeffer, or Frogs by Gail Gibbons.
• Frog Life Cycle Worksheet or plain pieces of paper for the students to sketch their own stages.
• Glue
• Scissors

Procedure

1. Ask the students what they know about how frogs are born and develop.  Read the chosen book or review the information given at one of the aforementioned web sites.
2. Pass out the Frog Life Cycle Worksheet or plain pieces of paper.  Have the students sketch or cut out the 4 main stages of frog development - eggs, tadpole, froglet, adult frog.  
3. If the students have cut the worksheet apart, they may glue them in the proper order on another sheet of paper.  If appropriate, have the students label the stages.  Older students may sketch the stages and label them on their plain pieces of paper.  Older students may also want to write one fact they have learned about each of the stages on their completed paper.

Other Lesson Ideas

1. Have every student write a "frog fact" on a lily pad shape.  Compile these facts into a book or display them in the classroom.
2. Discuss habitats by using a book such as The Magic School Bus Hops Home: A Book About Animal Habitats by Patricia Relf.  Classify animals by their habitats, desert, forest, ocean, pond, rainforest, etc.  Make large charts to list various animals under their habitat.
3. Classify animals according to the groups; amphibians, mammals, birds, reptiles, and fish.  The following link is helpful in making definitions Fact Monster: Animal Groups.  
4. Listen to the different frog sounds at the following link Frogs and Toads in Color and Sound and have a lesson on how sound is made through vibrations and how sound travels.
