Science Experiments for Middle School Students

Instructions

• 1

  Electrochemical Cell
  
  If you like electronics and always wanted to explore working of electrical appliances, then try to make an electrochemical cell. You just need two glass beakers and some chemicals along with a voltmeter for this experiment.

  Human Battery
  
  The logic behind this experiment is very much like an electrochemical cell. The only difference is that in making a human battery , you replace the salt bridge with your two fingers immersed in beakers.

  Match Rocket
  
  This experiment is probably the simplest and cheapest, as you can make a match rocket using a simple match stick and a piece of aluminum foil. The experiment is a simple demonstration of the actual rocket propulsion.

  Demonstrating Newton’s Laws of Motion
  
  If you try to demonstrate Newton’s Laws of motion this will be another good exercise for you towards learning some basic principles of physics. However, you need to have some necessary equipments to perform the three experiments involved in the demonstration of the three laws.

  Crush the Can experiment
  
  This experiment shows the affect of changes in external and internal temperature in relation to the atmospheric pressure acting on a body. You only need an empty tin with some cold water to perform crush the can experiment.

  Demonstration of Centripetal Force
  
  Demonstrating centripetal force simply shows that, for a body moving in a circle, there has to be a force directing its motion towards the center.

  Demonstration of Centrifugal Force
  
  Almost the same as centripetal force, demonstrating centrifugal force is to show how a body remains in equilibrium while moving in a circular motion.

  Neutralization experiment
  
  This is a very common experiment related to chemistry. The purpose of performing Neutralization is to show you can protect a marble floor if acid spills over it.
