Description
What our Bull Sharks lesson plan includes
Lesson Objectives and Overview: Bull Sharks 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 the habitat, diet, and behaviors of these unique sharks. 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 paragraph on this page provides a little more information or guidance on what to expect from 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 record any thoughts or ideas you have as you prepare.
BULL SHARKS LESSON PLAN CONTENT PAGES
The Bull Sharks lesson plan contains two content pages. It begins by providing a box of background information about this animal. Bull sharks are large, strong fish with thick bodies and short, blunt noses. They usually grow around 7 to 11 feet long and weigh up to 500 pounds. Some can even grow as long as a surfboard! Their bodies are grayish-brown on top and white underneath, which helps them blend into their surroundings in the water. Unlike most other sharks, bull sharks can live in salt and fresh waters. They are often found in warm, shallow waters near coasts, rivers, and lakes.
They are usually solitary, which means they like to live and hunt alone. However, they sometimes come together in groups called schools, especially when there is a lot of food nearby. These groups are not always permanent and are mostly made for feeding. Because they are so strong and curious, bull sharks can be dangerous if they feel threatened or mistake something for food.
When it’s time to have babies, female bull sharks go to calm, shallow waters to give birth. This helps keep the baby sharks, called pups, safe from predators. A female bull shark can have between 1 and 13 pups. The pups are born alive and fully formed, meaning they can swim and hunt immediately. Even though the mother does not care for them after birth, she chooses safe nurseries, like river mouths or estuaries, to give the pups a better chance of survival.
What They Eat
Bull sharks are carnivores, which means they eat meat. And they are not picky eaters! Scientists call this an opportunistic feeder, meaning the bull shark eats whatever is available. They eat many types of animals. Their diet includes fish, sea turtles, birds, dolphins, and sometimes other sharks. Sometimes, they eat crustaceans like crabs and shrimp. Because bull sharks can live in salt and fresh waters, they have a wide variety of food choices.
These sharks are fast and powerful hunters. They use their strong jaws and sharp, serrated teeth to grab and tear their prey. They have excellent senses that help them hunt. Their sense of smell is very strong, and they can detect even a small drop of blood in the water. Bull sharks also use their lateral line system, a row of special sensors along their sides, to feel vibrations in the water made by moving animals. These tools help them sneak up on prey and strike quickly, usually from below or behind, to surprise their target.
Other Interesting Facts
One of the most interesting facts about bull sharks is that they can survive in salt and fresh waters. Most sharks can only live in the ocean. Bull sharks are unique in that they have a special ability to control the salt levels in their bodies using their kidneys and rectal glands. This allows them to swim far up rivers and even into lakes. Scientists call this ability osmoregulation. Bull sharks have been found in rivers like the Mississippi in the United States and the Amazon in South America.
Bull sharks have short, broad snouts and a stocky, muscular build, and they exhibit aggressive behavior. They are known to bump into their prey before biting, which is called the bump-and-bite technique. This helps them test if the object is food and makes it easier to catch the animal. Their thick bodies and sudden attacks make them look and act like a bull, which is how they got their name.
They have a special sense called electroreception, which means they can detect the tiny electric signals made by other animals. Using electroreception, they can find fish or prey, even hiding in the sand or swimming in dark water. They do this using special organs on their snouts called ampullae of Lorenzini. This sense is invaluable in murky rivers where they can’t always see clearly. It makes bull sharks excellent hunters, even in hard-to-see places.
Why Bull Sharks Are Important
Bull sharks play a significant role in keeping the ocean healthy. They are apex predators, which means they are at the top of the food chain. Eating weak, sick, or slower animals helps balance the populations of fish and other sea creatures. This is important for the whole ecosystem. If bull sharks didn’t hunt, certain animals might become too numerous and hurt the environment by overeating or spreading disease.
While bull sharks are not endangered, scientists say they are near threatened. This means they could become endangered if we are not careful. People sometimes accidentally catch bull sharks when fishing or on purpose for their meat or fins. Pollution and dirty water also hurt the places where bull sharks live and have babies. We must protect the oceans and rivers and make smart fishing rules to protect bull sharks and other marine creatures. Let’s keep the shark population healthy for the future.
BULL SHARKS LESSON PLAN WORKSHEETS
The Bull Sharks 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.
SHARK PUPPETS ACTIVITY WORKSHEET
For the activity, students will follow the directions on the page to create shark puppets using clothespins. The worksheet provides a visual to help students understand the instructions.
BULL SHARKS REVIEW PRACTICE WORKSHEET
The practice worksheet lists 10 questions based on the content. 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.
