Science can be a lot of fun, and performing an experiment in your classroom can be one of the best parts of the year. Read this article for some ideas on science projects for your presentation.

What Soda Fizzes the Most?

Certainly, this has happened to you: you jostled the can of soda too much before opening it, and without warning, it practically explodes in your hand. Why not do this intentionally, and record some observations in the process? Here are some variables to think about:

  • How does the amount of fizz differ by brand, or by flavor?
  • How does the amount differ between bottles and cans?
  • How can you measure the amount of soda lost in the explosion?

Who Left This Print?

You've seen detective shows that lift fingerprints for evidence, but how does it actually work? By using actual fingerprint ink and dusting for prints, you can determine the identity of someone and then find out who among your classmates left it behind. Consider these ideas when doing this experiment:

  • How many people in the room should be printed?
  • How difficult is it to leave behind a fingerprint on different surfaces?
  • What happens when you only have a partial fingerprint result?

Which Brand Pops the Most Popcorn?

You've probably been disappointed when opening the microwave after waiting for popcorn, and after tearing into the bag, you find a few dozen unpopped kernels at the bottom. Why not turn this into an experiment to find out who the biggest offenders are? When you have the results, remember some of these thoughts:

  • How do the recommended times on each box differ?
  • Did butter or other added ingredients affect the number of unpopped kernels?
  • What brands of microwaves were used during the popping process?

What Kind of Music Affects Your Heart Rate?

With a simple pair of headphones and a stethoscope, you can determine which form of music is the most exciting or the most boring for your classmates. While you are recording the differences in their pulses, take a few moments to jot these statistics down:

  • What are the different tempos on each song?
  • How does having vocals affect the heart rate?
  • How do your classmates react to music from different areas of the world, or different time periods?

What Kind of Science Should I Use for My Experiment?

If you can't decide on an area of science you like the best, check out the following course from

The lessons in this course include chapters on everything from biology and chemistry to physics and even astrology. When you see something you like, think about the lessons that jumped out at you, and use those examples when coming up with your own experiment.
