List of Research Topics for Elementary Students

Kids will love these fun research project ideas!

1. Autobiographies

Nothing can be more interesting than learning about someone’s life from his or her own perspective.

Encourage your elementary students to read an autobiography of their favorite historical figure, sports player, or celebrity and then write a report about it.

Add extra credit points if they dress as their subject and present to the class!

2. Insects

Bugs are the world’s most abundant creatures, and there are so many different kinds for your students to explore – from beetles to butterflies, spiders to bees, grasshoppers to praying mantids.

Have your students report on the bug’s life cycle, what they eat, and where they live. 

3. Matter

Matter is everything that forms our universe and what’s in it.

Ask your elementary students to report on the different phases of matter plus give examples of each.

For bonus points, have them come up with a demonstration of the phases of matter. 

4. Natural Resources

Natural resources are vital to our existence and the way we live our lives.

Have your students research the natural resources they use everyday and trace the sources of these.

Ask them to come up with a plan to utilize the resources but also ensure the renewal of them for future use. 

5. Life Cycles

All animals and plants have different life cycles in which the stages of their growth and development cause changes to the organism in question.

Have your students pick an animal or plant.

They will then create a posterboard illustrating that organism’s life cycle in addition to a report highlighting the different stages of life.

6. Human Body

When it comes to research topics for kids, the human body is surely unique.

The human body is an intricate organism devised of multiple systems which work together to help its function.

Have your students choose a particular system of organs in the human body and report on the pieces of that system.

Ask them to delve into what makes that system so important and what would happen if that system were to malfunction.

7. Energy

There are various forms of energy, and each one is important in the physical world.

After learners select a specific type of energy, they will describe what it is, where it comes from, and speculate as to what the world would look like without it.

8. Earth’s Surface

The Earth’s surface is covered by land and ocean resting on top of moving tectonic plates.

For this research topics, elementary students may report on the differences between land and ocean plus how the formation of different structures is driven by the movement of the tectonic plates.

For extra credit, they can report on how the distribution of land and ocean on Earth has changed over time. 

9. Technology Over the Decades

Ever since the Industrial Revolution, technology has been rapidly developing with each passing decade.

Have your students report on what they think is the most important technological advancement of each decade over the past one hundred years.

Ask them to speculate on what the world would look like without these technological achievements. 

10. Magnets

Magnets are always a fascinating research topic for kids. Be sure to include fun experiments and demonstrations.

Have your students research how a magnet works plus how the Earth’s magnetic field affects biology, geology, and other sciences.

Ask them to make their own magnets. Then they can test different objects to determine which can be attracted to magnets and which cannot. 

11. Gravity

Gravity is a force we all feel on a daily basis but may forget that it’s there.

Have your students research Sir Isaac Newton’s famous discovery of gravity and report on how Earth’s gravitational field differs from that of other planets.

Ask them to speculate on how different life on Earth would be with more or less gravity. 

12. Simple Machines

Simple machines are fun to build, and they help us everyday to complete tasks easily plus efficiently.

Request elementary students to research and report on the different types of simple machines. They should also give real world examples of each one.

For bonus points, ask them to construct their own simple machine and demonstrate it for the class. 

13. The Water Cycle

Evaporation, condensation, and precipitation make the world go round.

Have students research and report on the water cycle. They will then create a poster board that illustrates the different stages of the water cycle.

Ask them to think about the conditions necessary in order for each stage to occur. 

14. Force and Motion

The laws of physics are important to understand and a great basis for your students is having them research Sir Isaac Newton’s three laws of motion.

Ask them to write a report on the discovery of the laws and what our world what look like without them.

For bonus points, have them give a demonstration reflective of one of the laws. 

15. Space

Space is arguably one of the most popular research topics for kids.

There are so many topics to tackle about space – from black holes to asteroids to planets to stars.

Elementary kids enjoy researching and reporting on a wide variety of space topics.

After they choose a space topic of interest to them, each will explain why he/she chose that topic.

For extra credit, have each child build a model of their idea and present to the class. 

16. Dinosaurs

This list of research topics for kids wouldn’t be complete without mentioning dinosaurs.

What kid doesn’t love dinosaurs?

Have your students choose a species of dinosaur to research and report on.

Ask them to describe where their species lived and what was their habitat.

What did they eat? Which animals may have eaten them? What did they look like, and how did they go extinct? 

17. American History

For being such a young country, America has a rich history already.

Prompt your elementary students to choose a species to report on.

They will include details such as habitat characteristics, food preferences, and particular behaviors.

Ask learners to explain what would happen to their chosen animal’s ecosystem if it were to go extinct. 

19. States of Matter

Solids, liquids, gases, make excellent research topics for kids. They are the perfect entrance into the world of chemistry. 

Noting the characteristics of solids, liquids, and gases along with providing examples is a great task for kids to perform.

A demonstration showing all 3 states is also a powerful activity.

20. Black History Inventors

When choosing research topics for kids, include subjects about famous black people in history.

While your elementary students may be familiar with Martin Luther King, Jr., there are countless black figures who hardly get the recognition they deserve.

Encourage your 1st, 2nd, 3rd, 4th, and 5th graders to explore the talented black innovators who achieved excellence despite significant racial barriers.
