The document discusses the concept of time from a physics perspective. It begins with an overview of how time is perceived and measured. Examples are given of how different beings experience the passage of time differently based on their lifespans. The lesson then relates time to sound frequency and how changing the pitch of a melody modifies it. Students experiment with modifying sound frequencies using audio software. Next, the lesson connects time to color frequencies and how different colors induce various human feelings. The class concludes with students translating a poem about making the most of time into English.

1. TIME IN PHYSICS
The lesson begins with a theoretical presentation of “time”: how we perceive time, how
scientists explain “time” and its passing and how we measure time. The teachers offers many
examples of the different ways of perceiving time in nature, comparing the ages of different
beings as related to human age.
Time has also inspired many writers and philosophers and has been the source of
inspiration for countless thoughts related to its irreversibility. The teacher presents some quotes
offering the students the chance to express themselves and comment upon those they have liked
the most.
The teacher skillfully relates the notion of “time” to Physics, by using sound and its
frequency. The teacher presents facts about frequency and the way in which it is perceived by the
human ear. Students use “Audacity” to modify the frequency of sounds: they choose a melody
and then operate changes on the frequency. Changing the pitch of sound will modify the original
melody, and the result will be the students’ original version of the song. They play the new songs
obtained this way – not very pleasant! They are happy that professionals work with this software,
and not amateurs…
The second part of the class relates time to colours, using their frequency. Students
present their views on what each colour from the light spectrum induces upon our mind, in terms
of human feelings and perceptions, offering examples from many domains such as history,
psychology, folklore, etc.
The class ends with a group translation (from Romanian into English) of the poem “Make
Time” written by Traian Dorz,. This activity and the actual message of the poem help remind
students what the importance of time really is and how we should enjoy every second of time we
are given.
