Energy is neither created nor destroyed: it is only transformed. There are many different forms of energy, including kinetic energy (the energy of motion), potential energy (energy that is considered stored because of an object’s position), mechanical energy (energy that performs work), and thermal (heat) energy. Kinetic and potential energy are often paired together in simple demonstrations, like dropping a book, jumping on a trampoline, or building cool machines like rubber band cars.

Hydraulic Crane workshop overview

The hands-on project serves as the best combination of hydraulics and lever with its types. It describes the concepts of hydraulics, pressure, and simple machines. It demonstrates Pascal’s law for describing pressure transmission and how it is used by simple machines. Students by doing this activity learn about different kinds of the lever and their practical applications.

Learning outcomes according to the national curriculum of general science

  • The activity focuses on the basic concepts of forces, pressure, and simple machines.
  • Describes Pascal’s law, its importance and applications.
  • Understanding about the working and uses of the simple machines in combination to the basic principles of physics.


  • Age: 7-12 years
  • of students: 30 (maximum)
  • Duration: 90 minutes

Air-powered rocket

The main emphasis is on the understanding of a model rocket, its aerodynamic structure, concept of pressure, Pascal’s law and its application in energizing of the model rocket. The activity deciphers the fundamentals of projectile motion and the factors affecting on it.
