Physics practical investigation
Lights and atoms
Principles of light
Investigate two-slit interference pattern using laser and diffraction grating.
Look at photoelectric effect
Fluorescene
Observe spectra of light
Sound waves
Investigate polarisation of microwaves
Investigate wavelengths and different interference patterns.
Investigate light in relation to voltage- velocity of particles
Electricity and magnetism
Electric fields
Explore relationship between electric field strength and distance from charged conductors.
E=F/q
Motion within electric fields
E=(delta)V/d
Teltron tube to investigate electron deflection path in relation to change in voltage.
Magnetic fields
Conduct an experiment based upon movement of magnets, could relate to circular motion.
Magnetic fields for straight current-carrying conductor.
Right hand rule
Look at solenoids
use Teltron tube to look at magnetic fields in relation to motion of particles
Resistance
Current
Motion and relativity
Projectile motion
Use a projectile launcher to investigate launch angle/height on range.
Analyse horizontal and vertical components of velocity.
Circular motion
Investigate centripetal acceleration using tuber, stopper, or weights.
For example: Investigate relationship between force causing centripetal acceleration and velocity of stopper.
Build model of satellite rotation to investigate radius.
Momentum
Look at collision of marbles.
