Their students' efforts come despite calls by activists and internet users to stop donating to a HK$100 million fund because of fears it will go to corrupt mainland officials.
A 6.6-magnitude earthquake hit Sichuan on Saturday, which killed at least 193 people, injured hundreds more and destroyed 17,000 homes.
Kevin Wong Ka-ming, chairperson of Fukien Secondary School's Student Union, and Torres Pit Hung-yau, the treasurer, urged students to make donations at the school's morning assembly.
"We are Chinese, too," Torres said. "We feel that we have a responsibility to do something for those who are seriously in need."
Amid concerns, members of the student union have decided to donate the money to Unicef, which they believe is a reliable aid charity. Unicef is one of a number of agencies that have raised more than HK$12.4 million so far.
The charity said all donations it receives will go directly to the affected area to provide psychological and medical support to local children.
Canadian International School students will have a dress-down day this Friday. Each participating student will donate HK$20 to the school's relief fund.
Fund-raising activities in aid of quake-hit Sichuan will also take place at Ho Fung College, Choi Hung Catholic Secondary School and Belilios Public School.
On Monday, Chief Executive Leung Chun-ying proposed to set aside HK$100 million for victims of the earthquake. A special Legislative Council meeting today will be asked to approve it.
