Children's Research Projects for the Third Grade

Kristine tucker.

Students in the third grade have the writing skills to complete basic research assignments, such as book reports and informational papers. As a teacher, your job is to come up with research project ideas that interest and inspire your students, such as assignments that center on geography, science or history. Research projects often include visual elements, such as pictures, drawings and graphs, to help students develop and present their ideas. Students must locate important facts, terminology and statistical information and cite their resources as needed.

• Beginner Biographies
• State Studies
• Astonishing Animals
• Simple Science Topics

1 Beginner Biographies

Assign a "famous person" project that requires students to research biographies of famous celebrities, historical figures, athletes, politicians or artists. Ask each student to choose a famous figure and create a biographical sketch on her. Help students organize their ideas into categories, such as background information, famous works and societal importance. Instruct students to include photographs of the person as part of the project. Provide historical or pop culture magazines that students can use to cut out celebrity images or ensure students have access to the Internet to print photographs. Students should organize the material in clear-cover report folders and read their biographical sketches aloud to the class.

2 State Studies

Instruct students to create a poster on the state of their choice. They must research general facts, such as the history, size, population, geography and leading industries in the state. They can use photographs, maps and graphs to explain the information. Give class time to research state facts in the school library or on the Internet. Teach students how to search for important details and take notes on the content they read. Encourage them to organize their posters with blocks of text and visual images. Display the finished posters around the room. To avoid too many students choosing the same state, assign a state to each child.

3 Astonishing Animals

Ask students to study and research any animal they choose and create a zoo brochure. Students can opt to make a trifold brochure or a one-page flier. They must include details about the animal's habitat, eating habits, lifestyle and role in nature. Instruct them to include images and photographs of the animal in the brochure. Students should also explain how their animal adapts to environmental changes, such as the four seasons and how the animal fits into the food chain. Some third-graders might know how to create brochures using software, but allow students to create them by pasting, gluing and writing on paper if they choose.

4 Simple Science Topics

Help students prepare for upper-elementary and middle school science fair projects by assigning science research reports. Ask students to choose a scientific topic, such as how frost forms, why oil separates from water, how seeds germinate or why rust forms on metal. Students must include an introduction, body and conclusion on their reports and provide sufficient factual details to support the content. According to the Common Core State Standards Initiative, the objective is to help students gain knowledge about their topics and support them with facts, definitions and details.

Sat / act prep online guides and tips, 113 great research paper topics.

General Education

One of the hardest parts of writing a research paper can be just finding a good topic to write about. Fortunately we've done the hard work for you and have compiled a list of 113 interesting research paper topics. They've been organized into ten categories and cover a wide range of subjects so you can easily find the best topic for you.

In addition to the list of good research topics, we've included advice on what makes a good research paper topic and how you can use your topic to start writing a great paper.

What Makes a Good Research Paper Topic?

Not all research paper topics are created equal, and you want to make sure you choose a great topic before you start writing. Below are the three most important factors to consider to make sure you choose the best research paper topics.

#1: It's Something You're Interested In

A paper is always easier to write if you're interested in the topic, and you'll be more motivated to do in-depth research and write a paper that really covers the entire subject. Even if a certain research paper topic is getting a lot of buzz right now or other people seem interested in writing about it, don't feel tempted to make it your topic unless you genuinely have some sort of interest in it as well.

#2: There's Enough Information to Write a Paper

Even if you come up with the absolute best research paper topic and you're so excited to write about it, you won't be able to produce a good paper if there isn't enough research about the topic. This can happen for very specific or specialized topics, as well as topics that are too new to have enough research done on them at the moment. Easy research paper topics will always be topics with enough information to write a full-length paper.

Trying to write a research paper on a topic that doesn't have much research on it is incredibly hard, so before you decide on a topic, do a bit of preliminary searching and make sure you'll have all the information you need to write your paper.

#3: It Fits Your Teacher's Guidelines

Don't get so carried away looking at lists of research paper topics that you forget any requirements or restrictions your teacher may have put on research topic ideas. If you're writing a research paper on a health-related topic, deciding to write about the impact of rap on the music scene probably won't be allowed, but there may be some sort of leeway. For example, if you're really interested in current events but your teacher wants you to write a research paper on a history topic, you may be able to choose a topic that fits both categories, like exploring the relationship between the US and North Korea. No matter what, always get your research paper topic approved by your teacher first before you begin writing.

113 Good Research Paper Topics

Below are 113 good research topics to help you get you started on your paper. We've organized them into ten categories to make it easier to find the type of research paper topics you're looking for.

Arts/Culture

• Discuss the main differences in art from the Italian Renaissance and the Northern Renaissance .
• Analyze the impact a famous artist had on the world.
• How is sexism portrayed in different types of media (music, film, video games, etc.)? Has the amount/type of sexism changed over the years?
• How has the music of slaves brought over from Africa shaped modern American music?
• How has rap music evolved in the past decade?
• How has the portrayal of minorities in the media changed?

How to Write a Great Research Paper

Even great research paper topics won't give you a great research paper if you don't hone your topic before and during the writing process. Follow these three tips to turn good research paper topics into great papers.

#1: Figure Out Your Thesis Early

Before you start writing a single word of your paper, you first need to know what your thesis will be. Your thesis is a statement that explains what you intend to prove/show in your paper. Every sentence in your research paper will relate back to your thesis, so you don't want to start writing without it!

As some examples, if you're writing a research paper on if students learn better in same-sex classrooms, your thesis might be "Research has shown that elementary-age students in same-sex classrooms score higher on standardized tests and report feeling more comfortable in the classroom."

If you're writing a paper on the causes of the Civil War, your thesis might be "While the dispute between the North and South over slavery is the most well-known cause of the Civil War, other key causes include differences in the economies of the North and South, states' rights, and territorial expansion."

#2: Back Every Statement Up With Research

Remember, this is a research paper you're writing, so you'll need to use lots of research to make your points. Every statement you give must be backed up with research, properly cited the way your teacher requested. You're allowed to include opinions of your own, but they must also be supported by the research you give.

#3: Do Your Research Before You Begin Writing

You don't want to start writing your research paper and then learn that there isn't enough research to back up the points you're making, or, even worse, that the research contradicts the points you're trying to make!

Get most of your research on your good research topics done before you begin writing. Then use the research you've collected to create a rough outline of what your paper will cover and the key points you're going to make. This will help keep your paper clear and organized, and it'll ensure you have enough research to produce a strong paper.

Do good lessons promote students' attention and behavior?

by Anke Wilde, Leibniz-Institut für Bildungsforschung und Bildungsinformation

Students are better able to regulate themselves in lessons that they consider to be particularly well implemented. This is the conclusion drawn from a study by the DIPF | Leibniz Institute for Research and Information in Education, published in the journal Learning and Instruction .

The link between teaching quality and self-regulation tends to be particularly true for pupils who have problems controlling their behavior and following lessons, for example due to ADHD symptoms.

Good teaching is characterized by the teacher leading the class through the lesson without disruption, encouraging the students to think, taking an interest in them and supporting them individually. The better the teacher is at this, the better the students will be able to regulate their behavior, for example by paying attention, cooperating and adhering to the class rules.

As a result, they learn better. This link, which has already been established in research, has now been examined in more detail in this daily diary study and evaluated with the help of multilevel analyses.

It became clear that the quality of teaching has an impact not only on self-regulation overall, but also in each individual lesson, as Dr. Friederike Blume, lead author of the now published study, summarizes the results.

"When teachers are particularly good at classroom management and providing student support in a lesson, students are better able to regulate their behavior. When these two characteristics of good teaching are not working well in a lesson, students also reported that they were less able to concentrate and engage."

Cognitive activation, the third characteristic of good teaching, was hardly relevant for self-regulation. Therefore, the personal relationship between teacher and student is particularly important, emphasizes Dr. Blume.

This is especially true for students who have difficulties with self-regulation, such as those with attention deficit hyperactivity disorder (ADHD).

"Many teachers find it difficult to establish a positive relationship with children with ADHD symptoms," says the educational researcher. "However, our study showed that in lessons where children with self-regulation difficulties felt particularly supported by their teacher, they were more likely to report being able to concentrate better and follow class rules.

"It is therefore worth taking a positive approach to these children in the classroom and showing a genuine interest in them, as this can reduce the pressure on teachers in the long term and bring more calm to the classroom."

The DIPF researcher also recommends that teachers ask their students for feedback on their teaching from time to time. Although this is still a taboo for many, it can provide valuable information on how to better tailor their teaching to the needs of individual students.

A total of 64 pupils in years 5 and 6 took part in the study. They did not necessarily belong to the same school or class, but were recruited through an email appeal to music schools, sports and leisure centers, for example.

At the start of the study, the children completed a questionnaire about general information such as their grade level and type of school, as well as how they rated their self-regulation skills. Over the next three school weeks, the children answered daily questions about the last lesson of each day.

The questions related to the quality of teaching (e.g., support from the teacher, disruptions in lessons, stimulation of reflection), as well as their ability to regulate themselves in that lesson (e.g., attention, impulse control, motor activity).

The links between the individual lessons and the corresponding daily entries were evaluated using multilevel analysis. Among other things, the results were analyzed on an intrapersonal level, which allows conclusions to be drawn at the level of the individual child. In addition, interpersonal associations were examined, which allows conclusions to be drawn about all participants together.

Limitations of the study

Studies with such an elaborate design, involving daily diaries, always aim to collect data in as short time as possible. As a result, teaching quality was only measured here on the basis of only few statements, which certainly do not cover all the characteristics of good teaching.

Future studies should therefore take a closer look at classroom interaction processes to explore which features of teaching are particularly beneficial, especially for children with stronger ADHD symptoms.

Furthermore, future studies must show whether the results found here apply to all subjects or only to certain subjects, and the role of different teaching methods.
