10 Key Words

Study the words grouped under the three themes before starting the practice items.

1. The Machine

Word	Meaning	Common collocations	Word forms	Example sentence	Memory tip
collider	A giant machine that smashes particles together at high speed.	hadron collider, circular collider	collide (v)	The circular collider sends particles around a long ring.	Think of two cars that collide head-on.
accelerator	A machine that speeds up charged particles to near light speed.	particle accelerator, linear accelerator	accelerate (v)	The laboratory built a new linear accelerator for radiation tests.	Like pressing the gas pedal (accelerator) in a car.
apparatus	The complete set of equipment designed for a scientific task.	laboratory apparatus, experimental apparatus	–	Technicians checked the cooling apparatus before firing the beam.	From Latin "prepare": the whole kit you prepare for one experiment.
instrument	A delicate tool used for precise scientific measurement.	measuring instrument, optical instrument	–	Each measuring instrument requires calibration every morning.	Like a musical instrument, it must be tuned for perfect notes.

2. The Research

Word	Meaning	Common collocations	Word forms	Example sentence	Memory tip
dataset	A structured collection of numbers or observations.	massive dataset, analyze a dataset	–	The team shared a massive dataset containing millions of collisions.	A "set" of "data" saved in one folder.
prediction	A statement about what will happen based on theory.	theoretical prediction, test a prediction	predict (v)	Their theoretical prediction matched the detector numbers closely.	Prefix pre- means before; you speak before it happens.
uncertainty	The known margin of doubt or error in a measurement.	measurement uncertainty, reduce uncertainty	uncertain (adj)	Repeated trials helped the team reduce measurement uncertainty.	Prefix un- means not; you are not completely certain.

3. The Matter

Word	Meaning	Common collocations	Word forms	Example sentence	Memory tip
proton	A subatomic particle with a positive electric charge in the nucleus.	proton beam, accelerate protons	protons (pl)	Electromagnets steer the proton beam through the vacuum tube.	Proton = Positive charge.
atom	The basic building block of all chemical elements.	single atom, split the atom	atomic (adj)	A gold atom has a heavy nucleus with electrons circling it.	Greek atomos: tiny piece that could not be cut further.
electron	A tiny particle carrying a negative charge that orbits the nucleus.	free electron, electron cloud	electrons (pl)	An electric field pulls each free electron toward the positive plate.	Think of electricity flowing through wires.
