Spotting animals in nature can be a rare experience, depending on the species and environment. Scientists often home in on animal clues to help identify different species. Take concepts learned in the previous lesson to a deeper level by teaching students how to use environmental information to identify variouys species. Conclude the lesson with creating an animal-wanted poster.
Lesson Objectives and Materials
- learn about different biospecies.
- learn different bird calls and sounds.
- create an animal-wanted poster.
- Build observation skills in the field
- Field guides or animal fact sheets
- NM data-collection form
- Animal silhouettes
- Pictures of different birds
- 12-by-18-inch or 18-by-24-inch construction paper
- Pens and colored pencils
- Field journals (bound scientific notebooks)
Identifying Species Through Observations
This lesson is broken into two parts. The first part focuses on using environmental clues for animal recognition. The second part helps students improve their listening skills. Follow these steps:
Part 1: Looking for Clues
Prelesson Preparation: Leave objects belonging to an imaginary person around the classroom, such as a backpack, a pencil holder, clothing, or a water bottle.
- 1. Ask students to take out their NM data-collection form and think about the section that asks how they have observed the animal. Brainstorm different ways to make observations, such as through sight and sound.
- 2. Ask students to form conclusions about the imaginary person from the objects you distributed throughout the classroom. Is the person male, or female? How old? What are the person’s hobbies?
- 3. Extend the idea to other species. Show animal silhouettes (owl, duck, squirrel, mole, swallow) one at a time. Discuss their differences.
- 4. Discuss habitats for each animal based on season, time of day, and temperature.
- Explain the difference between nocturnal species (such as owl) and diurnal species (such as duck).
- Explain migration and hibernation. For example, during the winter, some species migrate to the south (for example, swallows), some hibernate (for example, bears), and others move below the freezing line (for example, moles).
- 5. Discuss the types of clues animals might leave that lead to recognition, such as tracks, feathers, markings, and scat. Ask the students the following questions:
- Where are tracks found? For example, would a cougar walk out in the open looking for deer, or along the edge of the forest, where it can hide?
- What would feathers tell us? What about in different environments? For example, if there are a lot of feathers on the ground beneath a tree, the bird might have been killed by a hawk. If there isn’t a tree, the bird might have been killed by a mammal, such as a coyote or cat.
- What do different markings tell us? For example, a tooth or a colored feather provides information about the animal’s size and species.
Part 2: Listening for Clues
- 1. Explain that animals, especially birds, make different vocalizations, such as
- babies begging for food.
- alarm calls.
- territorial songs by males.
- courting calls.
- members of a flock checking in with one another.
- 2. Ask students to form teams to act out different vocalizations.
- 3. Go outside, sit quietly, and listen for birds. Quietly discuss which vocalization you may be hearing. It may take up to 20 minutes for birds to start "talking" after humans arrive, so move to the listening spot very quietly.
- 4. Blow up drawings of the following birds, cut them up into separate puzzle pieces (the younger the student, the bigger the pieces), and write the bird's vocalization on the back of each piece:
- Great horned owl (who, who)
- Barn swallow (eight . . . eight, eight, eight, eight)
- Northern flicker (wick-a wick-a wick)
- Common gray squirrel, alarm call (ack, ack, ack)
- American robin (jeep, jeep)
- Mallard(quack, quack, quack)
- 5. Ask students to put the puzzle pieces together and identify each bird, focusing on markings and shape, such as head shape, body shape, beak shape, legs, eyes, and tail.
Is the lesson too simple or advanced for your students? Here are some ways to customize the lesson based on grade level:
Grades K-1: Help students learn different bird sounds, and put the bird puzzle together as a group. Or make black-and-white copies of animal pictures and ask students to color the pictures while referencing field guides.
Grade 2: Ask students to choose a puzzle piece and practice its bird call, migrating toward other students who make similar calls.
Grades 3-5: Cut five strips of paper for each bird, with one side listing the vocalization of the bird and the other side listing a clue about the animal. Ask students to practice bird calls, find other students making the same call, and use field guides to identify the bird.
Grades 6-8: Ask students to listen to bird sounds online, and try to either identify the bird or draw the sounds as musical notes. Or create a drawing assignment that asks students to include color drawings of the bird in winter and breeding plumage.
This activity combines all the concepts students have previously learned about animal identification. Students will create an animal-wanted poster, and in doing so, they’ll apply their science, English, and art skills. This finished product will suffice as the practical component.
Here are the steps to follow:
- 1. Ask students to create an animal-wanted poster. Encourage them to look through field guides and observe local wildlife to find ideas for choosing their animal.
- 2. Post a list of requirements for the animal poster. It must include
- the student's nature name.
- the animal's common and scientific names. (Note that the NM code is made from the first two letters of each of the words in the animal's scientific name.)
- a life-size or scale pencil drawing of the animal, colored accurately with colored pencils.
- a drawing or description of the animal's location and habitat.
- a list of the sounds the animal makes.
- drawings of the animal's tracks, feathers, and scat.
- the animal's physical description, including its size, color, and characteristic markings.
- why the animal is wanted (for example, is it a predator, prey, or an invasive species?).
- 3. Discuss what other things students would like to include in the posters.
- 4. Explain the grading criteria of the project, and show the rubric as a basis. (See the Practical and Assessment section below.)
- 5. Work with students to create a model of the final poster, using an imaginary character, such as one from a cartoon or comic strip, for a demo.
- Use 12-by-18-inch or 18-by-24-inch construction paper for the background.
- Cut white paper into appropriate sizes for each of the parts of the poster so that one mistake won't ruin the entire poster.
- For older students, use software and graphics programs to create the poster.
- 6. Ask students to complete the poster. (For younger students, work as a class to develop the poster.)
- 7. Challenge older students by asking them to create clues about the animal before presenting the poster.
- Write five clues on different pieces of heavy construction paper.
- Cover the animal with the paper, and ask students to read each clue as they reveal different parts of the animal, bit by bit.
- Ask students to guess the animal after each clue is read. (You can see examples of this activity in the Microsoft PowerPoint presentations on the Field Guide Frenzy page of the NatureMapping Web site.)
Practical and Assessment
Test your students' ability to draw and identify different animal species. Have your students create an animal-wanted poster as described above.
How did your students do? Use this rubric to help assess each student's poster. Circle the appropriate box for each category. Base the grade on the total points (18-20 points = 4; 15-17 points = 3; 15 points or fewer = 2), or do it qualitatively.
