Yes. All power stations do that.
electrical energy to mechanical energy
Basically any device that needs to be plugged in so it could move would be an object that endures the transformation from mechanical to electrical energy. Those classroom objects could be a fan or a pencil sharpener.
One method which this could happen is you have mechanical energy, lets say you riding a bike, and attach a turbine to it which converts your mechanical energy into electrical energy. You then plug a light bulb into that, and the electric energy is converted into light.
Motors come in different forms but mainly internal combustion (gasoline and diesel) and electric. Combustion engines use the chemical energy in the fuel, electric motors use electric energy from a power plant.
Really a physics question which could go on for pages to be explained properly by someone in the know. To the layman it is Electron flow in the heating wire (electrical resistance) causing a collision at the atomic level producing radiant heat.

Could be the total of coal and nuclear
You could for instance convert the nuclear energy to mechanical or electrical energy and use it to pump water up into a high reservoir, where it will have potential energy.

During exercise, the body temperature rises and is regulated by sweating. In principle the excess heat could be harnessed by wearing a suit with waterpipes powering a small electrical turbine. As for the mechanical power, it could be harnessed for example through an exercise bicycle with a generator.
Electrical energy is got especially by the phenomenon of electromagnetic induction. To do such phenomenon we need mechanical rotational energy. This rotational energy could be derived from many ways. We may covert water into high pressurized steam by using heat derive from coal or atomic power. Other wise we can use the potential energy stored as we store water in a reservoir. This water as it falls it gives out kinetic energy which in turn rotates the turbine to produce electricity. Hence the electric energy thus produced is named as hydro electrical energy. Hydro stands for water.
Electrical energy could be produced from so many energy. Solar energy. This would help some voltaic cells to produce some potential difference which in turn would drive current when it is connected to an external device. Chemical energy. As we use cells, there chemical energy with its tendency such oxidising etc would create an emf between the terminals of the cell. Hence current flows as we connect the terminals to a device. Magnetic energy. Using magnetic energy and mechanical energy emf is produced as the magnetic flux linked with the coil changes. This is known as phenomenon of electromagnetic induction. Once again using thermal energy, by maintaining the junctions of thermocouples at two different temperatures, thermo emf will be produced.
Your body could could convert chemical energy into potential, kinetic, or mechanical energy.
Any device that has the ability to convert energy could be called a transducer. Some types of transducers are electrical, chemical, mechanical, and acoustic.
