2. Fingerprint Analysis
Fingerprint analysis is one of the most interesting and unique topics that can possibly be studied in a science project. A fingerprint consists of an outer skin layer, sweat glands, blood vessels, hair follicles and more. Unique traits produce a pattern on our fingers each time we touch something- like dust or ink on paper.
3. Blow Out The Candle With Chemistry
This article is about a project that use gas to blow out the candles. The project will demonstrate how pressure changes in a closed system can be used to control the flow rate of a gas. When pressure is applied, the volume of air molecules expands and they collide with more force at the nozzle end of the straw.

11. How Does Caffeine Affect Typing?
One of the best ways to improve your typing speed is by ingesting caffeine. Caffeine has a stimulant effect on the nervous system, making it easy for you to focus and type faster. This isn’t just an academic question: there could be theoretical implications for understanding how caffeine affects performance at a computer keyboard as well. Caffeine gives you more energy, meaning you can put in more hours at work or school without feeling tired.

13. The Effect Of Caffeine On Alertness
If you’re looking for a science experiment to conduct, the effect caffeine has on alertness is a great topic! For this project, you will need to buy one caffeinated beverage and one caffeine free drink. You should also keep track of how many hours since your last caffeinated drink and how many hours since your last sleep. After the test, analyze the data by seeing what effects it had on your alertness levels throughout the day.
