Get ideas for science experiments targeted at the high school educational level. Find out how to perform a science experiment and get a hypothesis to test.
Experiments by Grade Level
Caffeine Experiments
You've heard caffeine acts as a stimulant and that it may increase your concentration when you are under its influence. You can test this with an experiment.
Sample Hypothesis:
Caffeine and Typing Speed Experiment
Caffeine Science Fair Projects
Caffeine Chemistry
Sample Hypothesis:
- Caffeine use does not affect typing speed.
- Caffeine does not affect concentration.

Student Conformity Experiment
If you are in a large group of students and the instructor asks the class what 9 x 7 is. One student says it is 54. So does the next. Do you fully trust your answer of 63? We are influenced by the beliefs of the people around us and sometimes conform to what the group believes. You can study the degree to which social pressure affects conformity.Sample Hypothesis:
- Number of students will not affect student conformity.
- Age does not affect student conformity.
- Gender has no affect on student conformity.
Smoke Bomb Experiments
Smoke bombs are fun for kids of all ages, but probably not appropriate experiment subjects earlier than high school. Smoke bombs offer a interesting way to learn about combustion. They can be used as propellents in rockets, too.
Sample Hypothesis:
Non-Cook Smoke Bomb Recipe

Sample Hypothesis:
- The ratio of smoke bomb ingredients will not affect the quantity of smoke that is produced.
- The ratio of ingredients will not affect the range of a smoke bomb rocket.

Hand Sanitizer Experiments
Hand sanitizer is supposed to keep germs under control on your hands. You can culture bacteria to see if hand sanitizer is effective. You can compare different types of hand sanitizer to see if one works better than another. Can you make an effective natural hand sanitizer? Is hand sanitizer biodegradable?
Hand Sanitizer Health Hazards
Sample Hypothesis:
- There is no difference in the effectiveness of different hand sanitizers.
- Hand sanitizer is biodegradable.
- There is no difference in effectiveness between homemade hand sanitizer and commercial hand sanitizer.
