3. Demonstrations in exhibition
a. Music Therapy
- Comparing the heart beat rate of an
audience during normal activity and
listening to music with different tempos.
-listen to music with…
slow tempo →heart beat rate decreases
fast tempo
→ heart beat rate increases
3. Demonstrations in exhibition
b. Pillow of different materials
- Let audiences compare pillows which are
made of different materials
e.g. Memory foam, cotton etc.
- Explaining the difference between them
and why we chose the material to made
the pillow
3. Demonstrations in exhibition
