Description
What our Animal Defense Mechanisms 2 lesson plan includes
Lesson Objectives and Overview: Animal Defense Mechanisms 2 is a high-interest reading comprehension lesson plan. As such, students will practice various close reading and comprehension skills. In addition, they will learn about physical defense mechanisms that various animals have developed to ensure their survival. This lesson is for students in 3rd grade, 4th grade, and 5th 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.
Teacher Notes
The teacher notes page provides an extra paragraph of information to help guide the lesson. It explains that you can teach this lesson in a whole-class setting or as an independent, small-group activity. You can use the blank lines to write down any other ideas or thoughts you have about the topic as you prepare.
ANIMAL DEFENSE MECHANISMS 2 LESSON PLAN CONTENT PAGES
The Animal Defense Mechanisms 2 lesson plan contains three content pages. Animals live in habitats and face many dangers, like predators. To survive, animals have special body parts or behaviors called defense mechanisms. The mechanisms help animals protect themselves, escape danger, scare away predators, and ensure the survival of the next generation of the species.
In the Learn Bright lesson, Animal Defense Mechanisms 1, you learned about the different types of defenses. In this lesson, we will explore more in-depth the physical adaptations animals use to protect themselves. Many of these defense mechanisms are painful and can even result in the death of a predator. In fact, you may have encountered an insect defense mechanism, such as a bee sting! Though not deadly to most people, they can be life-threatening if you are allergic to bee stings.
Types of Physical Defenses
Venom
Venom is a liquid with special chemicals that can hurt, paralyze, or even kill other animals. Some animals, like the coral snake, have venom glands connected to their fangs. When they bite, venom travels through the fangs into the predator or prey. The venom can make muscles stop working or cause pain so the animal can escape safely. The Gila monster has venom in its saliva. When it bites, the venom enters the enemy and causes pain, making the predator think twice before attacking again.
Claws
Claws are curved, pointed parts at the ends of animals’ toes or fingers. They are made of keratin, the same substance as human fingernails. Claws help animals catch food, climb trees, or defend against enemies. When an eagle feels threatened, it can use its claws, called talons, to grip and scratch. Bears also have long, sharp claws that help them fight off threats. If a predator comes too close, a bear can swipe with its claws to protect itself.
Teeth
Teeth are hard structures in the mouths of animals. You may have been accidentally bitten by a pet, such as a cat or dog. It can be painful! Teeth come in different shapes for different jobs. Carnivores like lions have sharp teeth to cut meat and use them to protect themselves. A lion’s canine teeth are long and pointed for biting. When danger comes, lions growl and show their teeth to warn others to stay away. Wolves also have strong teeth to hunt and defend their pack. They can bite to warn or injure their enemies when they feel threatened.
Antlers
Antlers are made of bone and grow on the heads of male animals like elk and moose. They fall off and grow back every year. Antlers are used during mating season to fight for mates, but they are also helpful when defending against predators. When threatened, a moose might lower its head and charge, using its large antlers like a shield or battering ram.
Horns
Horns are different from antlers because they are permanent and grow throughout the animal’s life. Horns have a bony core covered by a layer of keratin. Animals like antelopes and buffalo use their horns to fight off predators. A buffalo might hook or jab with its horns if a predator gets too close. A rhino can use its horn to charge and protect itself if a lion attacks. Horns are a natural weapon for protection.
Tusks
Tusks are extra-large teeth sticking out of animals’ mouths like elephants and warthogs. They are made of dentine, a hard material in regular teeth. Elephants use their tusks to dig for water, peel bark, and protect themselves from predators like lions. If something dangerous comes near, an elephant can swing its tusks to push it away or break things in its path.
Stingers
A stinger is a small, sharp tool that delivers venom. Insects like wasps and bees, and even some sea animals such as jellyfish, use stingers. When a wasp stings, it injects venom from its venom gland through its stinger. This causes pain and swelling. Stinging is a strong warning to predators to leave the animal alone.
Hooves
Hooves are tough coverings at the end of animals’ legs, like horses, deer, and zebras. They are made of keratin, just like claws and horns. When scared, these animals may use their strong hind legs to forcefully kick backward. A zebra can kick so hard it could launch a lion into outer space! Not really outer space, but the kick can break a lion’s jaw or ribs, which gives the zebra time to run away.
Humans vs. Animals
As humans, we don’t experience the same need to protect ourselves from the same kind of dangers as other animals do. For example, if you live in the city, you will unlikely be attacked by a wild lion! This can sometimes lead us to being careless or not heeding the warning signs of animals who feel threatened, even domesticated animals like our pets. Unfortunately, it’s not unusual for humans to get bitten or stung at times when it could have been avoided.
Animals live in wild places where they must protect themselves to survive. Each defense mechanism is a special adaptation that helps them stay safe from predators. Some defenses involve chemicals, like venom, while others involve strength, speed, or other physical traits. Learning about animal defenses helps us better understand them. And the better we know them, the more we can protect them and their environments.
ANIMAL DEFENSE MECHANISMS 2 LESSON PLAN WORKSHEETS
The Animal Defense Mechanisms 2 lesson plan includes two worksheets: an activity worksheet and a practice worksheet. Each one will help students solidify their grasp of the material they learned throughout the lesson. You can refer to the classroom procedure guidelines to know when to hand out each worksheet.
CHOOSE YOUR DEFENSE ACTIVITY WORKSHEET
For this activity, students will select two defense mechanisms from the list at the top of the page. For each one, they must think of a wild animal that might try to attack them! Then they will fill in the blanks for each defense mechanism and wild animal they chose. Finally, they will draw themselves as a human (or a different animal) using their defense mechanism to escape danger.
ANIMAL DEFENSE MECHANISMS 2 PRACTICE WORKSHEET
The practice worksheet requires students to answer a series of 10 questions. These questions all relate to the content pages, so students will need to refer to them often for the answers. In addition, each question provides which reading tool the question corresponds to, such as text feature, vocabulary, or comprehension.
Worksheet Answer Keys
At the end of the lesson plan document is an answer key for the practice worksheet. The correct answers are all in red to make it easier for you to compare them with students’ responses. 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.
