Description

What our Amphibians lesson plan includes

Lesson Objectives and Overview: Amphibians explores the different kinds of these special creatures and their characteristics. Students will be able to identify and list the traits that group these animals together. They will discover what makes frogs and toads unique when compared to other groups of animals. This lesson is for students in 3rd grade and 4th grade.

Classroom Procedure

Every lesson plan provides you with a classroom procedure page that outlines a step-by-step guide to follow. You do not have to follow the guide exactly. The guide helps you organize the lesson and details when to hand out worksheets. It also lists information in the yellow box that you might find useful. You will find the lesson objectives, state standards, and number of class sessions the lesson should take to complete in this area. In addition, it describes the supplies you will need as well as what and how you need to prepare beforehand. This lesson will require scissors, colored pencils, glue or tape, and construction paper.

Options for Lesson

You will also find a number of suggestions in the “Options for Lesson” that you can incorporate into the lesson if you so choose. One suggestion is to assign students a specific species to research and present to the class. Then you can make a booklet using all the students’ presentations. Another idea is to bring in a live amphibian to the class to observe up close. You could also gather images of different amphibians and have students guess if each image is of a frog, toad, newt, or salamander. A final idea is to have students write a story about one of these animals and use terms from the content pages.

Teacher Notes

The paragraph on the teacher notes page provides some extra guidance or ideas for the lesson. In this case, it suggests teaching this lesson in conjunction with others that relate to animal classification or animals in general. You can use the blank lines to write down any other ideas or thoughts you have as you prepare to give the lesson.

AMPHIBIANS LESSON PLAN CONTENT PAGES

Classification

This lesson contains three pages of content. The first page explores animals in general. It reminds students how all animals have certain traits in common. For instance, they all need food and energy to survive, they all move, and they all grow. However, animals differ in a lot of ways. To keep track, scientists classify them into smaller and smaller groups based on their these traits. The main groups are called classes. These include mammals, reptiles, fish, and birds. Each group includes animals that have certain traits, like being warm-blooded, invertebrates, or living in water.

Students will discover that one trait that makes amphibians so unique is that they live both on land and in the water. The word “amphibian” comes from the Greek word that means double life. There are roughly 7,000 amphibian species in the world. They descended from fish and started to appear around 340 million years ago. Some have legs while others have no limbs at all.

Common Traits of Amphibians

Frogs and toads are among the most familiar amphibians. However, newts and salamanders are also a part of this special class. All the animals in the amphibian class have certain traits in common. They are all vertebrates, for instance. They have a backbone just as humans do. Their backbones are part of their exoskeleton, which are the bones inside the body that give the animal shape and support.

Students will learn that the reason these creatures can live both on land and in water has to do with gills. During part of their life cycle, they have gills to help them breathe under water. Then they develop lungs and legs, which help them live on land. Amphibians are also cold-blooded, meaning that they cannot control their body temperature. Instead, it matches the environment. If the weather is warm, they are warm, too. Amphibians also hatch from soft, jelly-like eggs and then undergo the process of metamorphosis.

Frogs, Toads, and Salamanders

Students will next learn that it’s not too difficult to tell frogs and toads apart. Frogs and toads, while similar, have a few key differing traits. Frog’s legs are longer, their skin is smooth, and they tend to look wet. They live near sources of water throughout their lives. Toads, on the other hand, have dry, bumpy skin and shorter legs. This is because they walk more often than jump, unlike frogs. They also don’t need to live close to water until it’s time to reproduce or lay eggs.

The two creatures do, however, both lose their tails when they become adults. Salamanders, on the other hand, do not. Instead, they keep their tails when they become adults. In fact, these lizard-like but scaleless animals can regenerate. If they lose a limb or their tail, it will just grow back. A caecilian is another type of amphibian that never grows limbs. Caecilians look like snakes or worms and burrow through mud using a pointed nose and strong skull.

Students will learn that the sizes of these animals can vary widely. The Chinese Giant Salamander can be 6 feet long and 140 pounds! The Goliath Frog can grow up to 15 inches long and weigh 8 pounds. On the other end of the spectrum, the smallest frog is a mere third of an inch. Students will also discover that these animals can live in a wide range of habitats as well, such as forests, meadows, ponds, and swamps. They are carnivores, meaning that they eat other animals. Their diets include spiders, beetles, and worms.

Key Terms

Here is a list of the vocabulary words students will learn in this lesson plan:

  • Classify: to separate or group things by similar traits.
  • Vertebrate: an animal with a backbone.
  • Exoskeleton: the bones inside the body of an amphibian that provide shape and support.
  • Metamorphosis: the transformation or physical changes that occur in stages in certain animals.
  • Regenerate: to grow back.

AMPHIBIANS LESSON PLAN WORKSHEETS

The Amphibians lesson plan also includes three worksheets. Each one will test students’ comprehension of the material and help them solidify their grasp of the content. You can use the guidelines on the classroom procedure page to know when to hand out each assignment.

FROG LIFE CYCLE ACTIVITY WORKSHEET

For the activity, students will create dioramas that display the different stages of an amphibian’s life cycle. They will choose which animal’s life cycle to display and create its habitat in a shoe box or other small box. To create the different stages, students can use modeling clay or other materials. Page 5 of the lesson plan document will help them decide which stages they need to create. The worksheet provides a background image that students can use if they don’t want to make their own.

AMPHIBIANS PRACTICE WORKSHEET

There are a few sections on the practice worksheet. First, students will match definitions to the correct description. There are 12 total statements in this section. Next, students will place each of the five stages of the metamorphosis of a frog in order from 1 to 5. Finally, they will answer five questions that relate to what they learned from the content pages.

WORD SEARCH HOMEWORK ASSIGNMENT

For the homework assignment, students will complete a word search. There are 20 different species of toad, frog, salamander, and newt in the word bank for them to find.

Worksheet Answer Keys

At the very end of the Amphibians lesson plan are three answer keys for the activity and practice worksheets and the homework assignment. The answer key for the activity provides two examples of dioramas that you could show students to help them figure out how to complete the activity correctly. The practice worksheet answer key provides the correct answers in red. For the homework answer key, the words in the word search are highlighted in pink to make it easy for you to compare students’ work. If you choose to administer the lesson pages to your students via PDF, you will need to save a new file that omits these pages. Otherwise, you can simply print out the applicable pages and keep these as reference for yourself when grading assignments.

Good quick packet

We are using this packet to supplement science during the schools at distance learning. This packet had interesting information about amphibians and even a crossword that allowed learning in a different way.
