Offering you a complete choice of products which include first order lever scince park model, second order lever science park equipment and coservation of energy sciene park model.
A first-order lever is a simple machine where the fulcrum (the pivot point) is positioned between the effort (the applied force) and the load (the resistance being moved). This arrangement can provide a mechanical advantage, making it easier to lift or move the load, or it can increase the distance the load is moved for a given effort.
This is science model of conservation of energy for school education.It explains about energy remains same at the every position.with the help of this model students learn practically and do with hands and understand it very simple way.The principle of energy conservation states that energy is neither created nor destroyed. It may transform from one type to another. Like the mass conservation principle, the validity of the conservation of energy relies on experimental observations; thus, it is an empirical law.
