PIRA Code(s): 3D32.15 Set up time:No setup required. Operation: First, slide blow into the mouthpiece located at the top of the whistle. Next, move the piston to create different frequencies. If you have trouble moving the piston and blowing into the whistle simultaneously, have another person work the piston. Physics and Science Concepts: Waves, Oscillations, Frequency, Pitch Safety: Do not blow too hard or for extended periods of time as this may cause dizziness or headaches. Clean the mouthpiece in between use.
PIRA Code(s): 6A20.45 Set up time:none Operation: Use the different types of mirrors to compare reflection. Physics and Science Concepts: Geometrical Optics, Reflection Safety: Do not shine bright light into mirror.
PIRA Code(s): 6A40.99 Set up time:none Operation: Shine a focused beam of light at one of the facets of the prism. Light is refracted and split into its constituent wavelengths (i.e. Colors of the rainbow). These can be used with various other optical experiments. Physics and Science Concepts: Optics, Refraction Safety: Edges and corners may be sharp
