Gold Leaf Electroscope
This instrument is used for the detection of charge and measuring
static electricity.It works on the principle that the like charges repel
each other.
Static and Kinetic Friction
Static friction is what keeps the box from moving without being pushed, and it must be overcome with a sufficient opposing force before the box will move. Kinetic friction (also referred to as dynamic friction) is the force that resists the relative movement of the surfaces once they're in motion.
A Pulley as a Simple Machine
A pulley is a simple machine consisting of a wheel turning on an axle. Pulleys are often used singly and in combinations to do work.

Pencil Lead Conducts Electricity
Pencils Lead Conduct Electricity and Act as Resistors Too.
The “lead” in a pencil isn't actually made from lead. It is
made from a form of carbon called graphite. The graphite is mixed with clay and
formed into long thin pencil lead.

Foward current in diode.
A diode is a semiconductor device that essentially acts as a one-way switch for current. It allows current to flow easily in one direction, but severely restricts current from flowing in the opposite direction.
Heat - Bar and Gauge
After heating, the gauge shows that the bar has increased in length, which is called linear expansion
