Basics on the topic Comparing Two Sources on the Same Topic

Comparing Two Sources on the Same Topic – Introduction

When researching a new topic, it is important to combine the information from more than one source. We need to use at least two sources to speak knowledgeably about the topic.

When using two or more sources on the same topic, we need to compare and contrast two texts to see which information from each source we should include in our essay or presentation. In this way, we can make sure that we have a more complete understanding of the subject we are researching.

Comparing sources is a useful skill, which is why students usually learn to compare and contrast two texts on the same topic.

Comparing Two Sources on the Same Topic – Graphic Organiser

When you compare and contrast two similar texts, you can use a graphic organiser. When reading each of the two texts, list key points from each text in the dedicated column.

Let’s have a look at two texts examples and try to compare and contrast them using the graphic organiser above. Here is the first text:

Sharks are predatory animals that live in the ocean. There are over 500 different species of sharks, ranging from tiny sharks like the dwarf lantern shark, to huge sharks like the whale shark, which can grow as long as 49 feet! Sharks are skilled hunters that can easily locate prey in the water with the help of their special senses.

From this source we learn that sharks are predatory animals, there are over 500 species of sharks, the smallest shark is called the dwarf lantern shark and the biggest is the whale shark, which can grow as long as 49 feet, sharks are skilled hunters and they have special senses that they use to locate prey. Let’s add these details to our graphic organiser:

Now, let’s analyse the second source:

Sharks are amazing creatures that can be found in every ocean in the world. While most people think sharks are terrifying, they are very important to the ocean. They help keep the balance of marine life and play a crucial role in the ecosystem. Unfortunately, more than 50 species of sharks are endangered due to commercial fishing and ocean pollution.

From this text we learn that sharks can be found in every ocean in the world, sharks are important to the ocean, they help keep the balance of marine life and play a crucial role in the ecosystem, more than 50 species are endangered because of commercial fishing and ocean pollution. We can list these ideas in the graphic organiser:

Now, we can clearly see all the important information we have gathered from the two texts. While some information was the same in both texts, there were also different facts included. This is why we need to use more than one source: if we’d had only the first source available, we wouldn’t have known about the information from the second text.

Comparing Two Sources on the Same Topic – Summary

When researching a topic, it is important to combine the information from more than one source. To speak knowledgeably about the topic, we need at least two sources.

The graphic organiser can help us compare and contrast the most important points presented by two texts on the same topic:

Text 1 – Key Points	Text 2 – Key Points
- predators - live in the ocean - skilled hunters - use special senses to locate prey	- live in every ocean - keep balance of marine life - play a role in the ecosystem - are endangered because of fishing and pollution

Now you are ready to compare and contrast two sources for your research! For more practice, watch our video and use our worksheets on comparing two sources on the same topic!

Transcript Comparing Two Sources on the Same Topic

Comparing two sources on the same topic. "What are you doing?" "I'm giving a historical presentation, so I am researching my great grandfather, Chester Maxwell, the Third." "Never heard of him." "Let me find my resources and then tell you all about him." When researching a topic it is important to integrate, or combine, the information from more than one source. We use at least two sources to help us write summaries or speak knowledgeably about the subject. To compare the information, we can use a graphic organiser. Let's read the first text, highlighting key details and listing the important facts and do the same for the second text! From our lists, we will be able to summarise the topic by paraphrasing all the important details. Here's the first source about Pearl's great-grandfather. As a young cephalopod, Chester Maxwell the Third was known for his curiosity, which would often get him into trouble. One day, while exploring outside of his den, Chester encountered a shark! A frightened Chester sprayed his ink at the predator and got away. That evening he noticed ink still remained on a tentacle. As he swiped it across seaweed, a lightbulb went off! Chester immediately went to work at bottling his ink, and soon his empire was born. From then on, he was known as the Ink Master. From this source, we learn Chester was known for his curiosity, he sprayed ink at a shark, the ink swiped off onto seaweed giving him the idea of bottling his ink to sell. He built a successful ink empire and was known as the Ink Master. Let's list these details in our graphic organiser, paraphrasing them like this. Now, let's analyze the next source. Chester Maxwell, the Third, the sea-renowned ink maker and businessman, had another side to his personality. He was a very talented writer. His books were just as popular as his ink business, but nobody knew because he went by the name, Algernon Lewis when writing. In his later years, he wrote the classic, Fry in the Well, which many believe was the story of Chester’s childhood. What details do we learn in this source? Chester had another side to his personality, he was a talented writer, his books were popular, nobody knew he wrote them because he went by the name Algernon Lewis. He wrote the classic, Fry in the Well, which was believed to be about his childhood. We can list these ideas in the organiser by paraphrasing them like this. Looking at our information gathered, we can see why reading multiple sources is important. If we had read only source one, we would only have learned about Chester's ink empire. We wouldn't know that he was a talented writer that wrote many famous books and went by another name. We learn that information in source two. Reading both sources gives us a more complete picture of our topic. While Pearl summarises the information for the presentation, let's review. Remember, when learning about a topic it is important to integrate, or combine, the information from more than one source. The information gathered can help us write strong summaries, or speak knowledgeably about a subject. "Chester Maxwell, the Third, was an inventor, businessman and writer. A chance encounter with a shark would change his life forever. He revolutionised ink production, making it easier for writers to tell their stories. Chester was a great writer himself. He wrote several books under the name of Algernon Lewis. His greatest work was the memoir called, Fry in the Well."
