TASK 1

To begin, choose a large piece of construction paper (11 x 17) and fold it in half to create a hamburger fold so that the construction paper looks like a large card. This is your science log. Your science log is very important. Each day you will add new information to your log that supports your research on the life cycle of a frog.

Next, click on the link below and print the cover sheet for your science log. Color the cover sheet and then glue it to the front of the construction paper. 

Then, click on the link below and print out the KWL chart and complete the first two sections as best you can. Relax and let your mind explore. This is a time for you to make connections to your prior knowledge about frogs. Think about books you have read, movies you have seen, and your personal experiences with frogs. Record what you know in the section titled What I Know. Then, think for a moment about what you would like to learn from the WebQuest. Record your questions in the section titled What I Want to Know. The last section will be completed at the end of the WebQuest.

AMPHIBIANS

Frogs are amphibians. The word amphibian comes from the Greek word "amphi" or "bios" which means "double life". Why do amphibians live a double life? 

Amphibians are cold-blooded animals that possess backbones. Their features (how they look) lie somewhere between fish and reptiles. Amphibians spend time both in water and on land. Their larvae (eggs) grow and mature in the water and breathe through gills like fish. However, adult frogs breathe air through their lungs and skin.

FROG HABITAT

Have you ever wondered where frogs live? Frogs live on every continent in the world except Antarctica.

Frogs must live in or near a place that has water. Most frogs live near lakes, rivers, and streams. Frogs need the water to keep their skin moist, which is necessary for their survival. Another reason frogs live near water is because they need the water to lay their eggs. Frogs begin their life as larvae (eggs). Frogs lay their eggs in the water. Frog eggs are protected by a jellylike coating. Without water this jellylike coating would dry out and the frog eggs would die.

Some frogs never enter the water. These frogs live on land or in trees and only enter the water to mate. There are other frogs that are known as burrowers. They have very short legs and cannot hop. These frogs burrow into the sand or mud to keep their skin moist.

Do you know some of the frogs native to Georgia? Did you know that Georgia has several different species of frogs including tree frogs?

Click on the link below to see all the frogs native to Georgia. You can even hear what they sound like. Way Cool! What's your favorite species of frog?

Frogs of Georgia

Another important part of a frog's habitat is the food it eats. Amphibians, especially frogs, are carnivores. Carnivores are meat eaters. Frogs eat other animals in order to survive. A frog's diet consists mostly of bugs and worms. Bigger frogs also eat other small fish, reptiles, and mammals such as lizards, newts, and other small frogs. However, frogs do not hunt for their food the way a lion might. Frogs have big eyes on the top of their head so they can see all the way around. When they spot a tasty treat they use their tongue to lasso in the bug or worm.

TASK 3

Print the Science Journal Note Taking Page and then read the information about Metamorphosis. 

Did you know that just like butterflies a frog goes through a metamorphosis?


GUIDING QUESTIONS

What is metamorphosis?

How many stages are there in a frog's metamorphosis?

What are the stages of metamorphosis for a frog?

METAMORPHOSIS

The process that transforms a frog from water to land is called metamorphosis. Metamorphosis is the transformation from an egg into an adult. Frogs change from egg into an adult frog. Frogs go through four stages in their life: egg, tadpole, metamorph (froglet), and adult. This metamorphosis is also known as the frog's life cycle.


http://www.svgs.k12.va.us/Outreach/Activities/sickfrog/instructions.html

The phase between the tadpole and metamorph (froglet) can take anywhere from 3 weeks to a year depending on the species of frog. Many diagrams showing the life cycle of a frog will break down these two stages into more steps so that it is easier to see the entire transformation, but there continues to be only four stages.

You will visit the following websites to read and learn more about the metamorphosis of a frog. You will see a number of pictures that show various stages of a frog's lifecycle. Before beginning your research take a moment to print out the Frog Metamorphosis chart which will help you to identify the different life cycle stages.

     
  • The Garden Pond Page (March)
    This webpage has a good number of pictures that show the
    different stages a frog goes through. Take a close look at  
    the eggs also called frog spawn.
     
  • The Garden Pond Page (April)
    More pictures from the Garden Pond. Take a close look         at the tadpoles. You can begin to see the tadpoles as they
    grow legs. The very last picture on this page is really interesting because it shows the froglet with both
    its legs and tail.
     
  • KidZone Frog Facts
    A website that explains many facts about frogs including      
    a frog's metamorphosis.
     
  • The American Museum of Natural History
    A website that explains the metamorphosis from tadpole      
    to a frog.
     
  • Harcourt Science Publishers
    Scroll down to Chapter 2 and click on The Life Cycle of a Frog. You will need your headphones.

 

 


  Extend & Practice

Now that you have learned more about the metamorphosis process it is time for a short practice.

  • Frederick's Cycle of Life
    Help Frederick by placing the stages of his life in the correct sequence. Follow the directions to move through the puzzle.

     

  • Lifecycle Puzzle
    Click on each puzzle piece and drag it to its correct location. 

 

 

 

TASK 4

  • Print the KidZone Life Cycle of a Frog handout. Use the handout to sequence          
    the stages of a frog. You will need glue and scissors.
     

  • Print the information sheet about Frogs (Enchanted Learning) and answer the questions.

 

 

TASK 5

  • Print the poem titled Five Little Tadpoles and complete the response to literature activity. Then print the Put Together a Frog activity and use the pieces to recreate the stages of a tadpole.

  • Print the writing prompt titled From Tadpole to Frog and write a short story        
    that explains what happens to a tadpole as it grows into an adult frog.

 

 

 

TASK 6

  • Print the Jumping Frog Origami activity. Follow the directions to fold the frog
    (ask your teacher for help if you have trouble). Next, place a piece of masking
    tape on the floor. This will be the starting point for the jumping frog. Place
    the frog on behind the masking tape (start line) and make him jump. Use a ruler to
    measure how far your frog jumped. What could you have done differently to make
    the frog jump even further?
     

  • Print the From Frog to Tadpole Math Performance Task and then solve.
