Record observations and also analyze the materials used in each type of paper to hypothesize why the paper might be difficult or easy to tear.

Materials Needed: Different types of paper, ruler or measuring tape, weights or force gauge, clamps or clips.

18. Pendulums

In this project, construct your own basic pendulum with string and a weight, and see how the length of a pendulum affects its period (the time it takes to complete one full swing). You can also conduct trials where pendulums of varying lengths are released from the same angle, or vary the angle from which the pendulum is released. 

Materials Needed: Pendulum apparatus (can be as simple as a string and weight), stopwatch or timer, protractor for measuring angles.

19. DIY Catapults 

In this project you’ll explore the principles of projectile motion and trajectory. Build a simple catapult or trebuchet and investigate how launch angle and projectile mass affect the trajectory of a launched object. If you want to take the project a step further and add a history component to it, explore a few various catapults that were used in ancient or medieval times and observe the differences in their launch angles and typical projectile masses. Were these catapults effective?

Materials Needed: Catapult or trebuchet construction materials (wood, rubber bands, etc.), objects that the catapult can launch, measuring tape or ruler.

20. Friction 

Explore the concept of friction by pulling objects across different surfaces and measuring the frictional force. You can investigate how different surface textures impact how easy it is to pull the object across the surface. To take the project to the next level you can share your findings about one real world application where the concept of friction is very important (think things like sports or transportation). 

Materials Needed: Objects of different weights, various surfaces (e.g., wood, metal, sandpaper), force sensor or spring scale, ruler

21. Studying the Effects of Music on Stress Reduction 

We all have our playlists or songs that help us relax, but how can we actually confirm that music actually plays a role in reducing stress? In this project you can conduct experiments where participants listen to different types of music (e.g., classical, jazz, nature sounds) and their physiological stress responses (e.g., heart rate, cortisol levels) are measured before and after listening to the music. Before conducting the experiment see if you can do some preliminary research on the topic and what other experiments have been done. 

Materials Needed: A device to play, physiological monitoring equipment, stress assessment scales.

22. Ocean Acidification and Coral Bleaching 

Study how ocean acidification, driven by increased carbon dioxide levels in the atmosphere, impacts coral reef ecosystems. You can also look into coral bleaching and learn how it’s also related to ocean acidification. This project can be a bit more focused on research rather than actual experimentation, but if you’d like to develop a model to demonstrate ocean acidification and see how carbon dioxide affects water we encourage you to do that as well.

Topic: Chemistry, marine biology

Materials Needed: Cups, water, acid base indicator, baking soda, vinegar

23. Studying the Effects of Deforestation on Local Climate Patterns 

Learn how deforestation affects regional climate conditions such as temperature, precipitation, and humidity.

To get you started, check out this article on how scientists have been tracking deforestation in the Amazon for decades .  

Topic: Climate, environmental science

Materials Needed: Satellite imagery or aerial photographs

24. Investigating Sinkholes 

Sinkholes may seem like a chaotic once in a lifetime phenomenon but there are actually geological processes involved in the formation of sinkholes. Explore these processes and their potential hazards to human settlements. To learn further you can research specific areas that are known to have a lot of sinkholes and try to understand why this occurs from a geological perspective.

Topic: Geology

Materials Needed: None

25. How Color Affects Mood and Emotion Description

Explore whether different colors influence people's mood and emotional state. You can design experiments where participants are exposed to different colors through images or objects and their mood responses are measured with self-reported scales or surveys. Analyze data and see if you can find any patterns. The more subjects you have in your experiment the better!

Topic: Psychology

Materials Needed: Images or objects that show mainly one color

Match Your Project to Your Interests

This seems obvious, but it’s really helpful for kids who feel overwhelmed by all the choices. It’s also a good way to get reluctant learners more excited about science fair projects. Encourage students to think about what they love to do in their spare time. How can they turn that into a project?

For instance, kids who love sports might explore the most effective stretches for warming up, or methods for throwing a football farther and more accurately. Music lovers can learn how sound waves work, or discover the link between music and emotions. It’s all about starting with something you love.

Challenge Yourself, But Keep It Realistic

Science fair projects need to be something kids can complete by themselves or with adults in support roles only. If a student picks something that’s way beyond their skill level, chances are the parents will wind up doing most of it. That being said, the point of the project is to learn and grow. Aim to learn something new, whether it’s knowledge or skills, by setting measurable goals.

If You Want To Win, Be Innovative

For science fair contests with prizes, the more creative you can be, the better. Projects that address real-world problems with new and interesting solutions often catch the judges’ eye.
