1. Information
Chemistry•Communication Challenge, aka “Chem-dot-Comm”, is a biannual scientific communication event organised by the Department of Chemistry, National University of Singapore. The contest, previously known as the Chemistry Speech Contest was first organised in the 1970s. The competition has aimed at providing secondary school students nationwide an introduction to advanced topics in chemical sciences and their unlimited applications vital to our industry, economy and society.
It is an opportunity to expose the students to public speaking before their peers and teachers, as well as engage them in exploring new ideas and deeper understanding of significant topics in Chemistry. Such competitions will motivate students to attain higher standard of scientific oral communication by competing against, and learning from their peers nationwide.
Chemistry•Communication Challenge is held in 2 languages : English and Chinese and implements a web-based presentation. Participating schools are encouraged to use information technology (IT) to demonstrate difficult chemical concepts. The key advantages of IT are the ease of employing multimedia presentations in place of live demonstrations, as well as interactivity. Through the challenge, it is hoped that participants would be able to develop innovative techniques to highlight and convey difficult scientific concepts in an effective and informative manner.
This year we implement new thing i.e. teams that are keen to present in other languages (e.g. Malay, Tamil, German, etc.) are welcomed and certificate of participation will be awarded.


The theme for Chem•Comm 2015 is "Sustainable Chemistry”. The theme challenges the chemist to provide long term creative solutions which help us meet our day-to-day challenges and preserve nature at the same time.

    2. Each Team comprises of 4 participants.
    3. Each school can register maximum 3 teams for each category


4. Rules

  1. Each team has to give a presentation for a web-based presentation that they have designed. Two of the team members will speak on the team's topic. The two remaining members will assist in the presentation and answering of questions.

The presentation from each team will consist of 2 parts, i.e. a web site and a computer slide presentation (e.g. Microsoft PowerPoint™). 

    • Web site: The site should consist of a minimum of 5 pages, but not exceeding 10MB, including references and images and/or movies. Unless produced by you, all media used in the web site MUST reference a source, either scanned from a book or downloaded from a CD-ROM or another web site. The site must be ready as is to go online.
    • Presentation: The presentation is not simply a demonstration of the web site. It should present the important points of the team's chosen topic, and then showcase the contents of the web site in providing more information about the topic. That is, the web site is a supplement to the presentation.


The following guidelines may offer some help to the participating teams:

    • Speaker 1 will act as a Chairperson for the team. He/she will introduce the presenters, and the topic to be presented.
    • The presenters (Speaker 2 & 3) will deliver the slide presentation, followed by a brief demonstration of the web site by Speaker 4.
    • After the presentation, Speaker 1 will highlight the main points, before thanking the presenters and closing the team's presentation.
  1. Each team is to submit 2 different topics on the theme given before the deadline stipulated. The Organising Committee will select one from the topics submitted and inform the participating teams their respective topics in advance of the contest.
  2. Where a school is represented in both the English and Mandarin categories, DIFFERENT topics are to be proposed for each category. The topics must be ones on which the school has NOT spoken in the previous 2 Chem•Comm contests.
  3. All teams in the finals must propose 2 DIFFERENT topics to the one spoken on in the preliminary round (see b above).
  4. Participants will design their own presentations and web sites based on the topic.
  5. An overhead projector, a visualiser, a PC, a USB drive and a CD-ROM drive will be provided during the competition. Participants are, however, advised to bring along their own notebook and drives. The team is only allowed to refer to the presentation and web site during the speech. No other props are allowed.
  6. In the preliminary rounds, the time allotted for each team will be 12 minutes. A warning will be given at the 9th minute. In the finals, the time allotted for each team will be 15 minutes. A warning will be given at the 12th minute.
  7. After the presentation, question(s) will be put to each team by the judges. During the finals, questions will also be accepted from members of the audience and opposing teams. The question(s) will be based strictly on the topic presented. ANY of the four team members can provide the answer(s) on behalf of the team. The question period shall not exceed 5 minutes in the preliminary rounds and 10 minutes in the finals.
  8. The SAME four team members must participate in BOTH the preliminary and final rounds. The choice of the first two speakers is at the discretion of the team.
  9. The decision of the judges is final.
