Building Science & Maths concepts through real experiences.
We encounter various types of lever in our everyday lives: opening a drink with a bottle opener, cutting paper with scissors, taking the lid off a paint pot using a screwdriver, and – the simplest of all – playing on a seesaw in the park. Yet, the principle of…
A simple machine is a mechanical device that changes the direction or magnitude of a force. In general, they can be defined as the simplest mechanisms that use mechanical advantage (also called leverage) to multiply force. Usually the term refers to the six classical simple machines that were defined by…
Air is a matter of substance, and hence it contains weight and other assets like density and pressure. Generally, the air surrounding us or objects does not show any pressure because it surrounds with equal pressure. In this science activity, we will observe that air shows its pressure when the…
