1. Information

Chemistry•Communication Challenge, aka “Chem-dot-Comm”, is a biennial scientific communication event organised by the Department of Chemistry, National University of Singapore. This competition has a long history and started in the 1970s as the Chemistry Speech Contest. Its main objectives is to provide secondary school students nationwide an introduction to advanced topics in chemical sciences and their vital role in our industry, economy and society. It is an opportunity to expose the students to public speaking before their peers and teachers, as well as to engage them in exploring new and advanced concepts in Chemistry. Through competition, we hope to motivate students towards attaining higher proficiencies in scientific oral communication by challenging with and learning from their peers nationwide.

Chemistry•Communication Challenge is conducted in English (only) through a web-based presentation format. Participating schools are encouraged to use information technology (IT) to articulate and convey advanced chemical concepts. The key advantages of IT over live demonstrations is that it can leverage on the accessibility to a wide audience and connect with them through the interactivity of web-based media. Through this challenge, we hope participants will be able to develop innovative techniques to instruct difficult scientific concepts in Chemistry in a highly effective and informative manner.

Our theme for the 24th CHEM•COMM CHALLENGE 2017 is "C3 – Climate Change & Chemistry”. The theme challenges the competitors to describe the important role of Chemistry toward the understanding and management of Climate Change. This follows the heels of the recently concluded Paris Agreement on Climate Change, ratified by over 100 nations worldwide, and will come into force in November 2016. This agreement seeks to “strengthen the global response to the threat of climate change by keeping a global temperature rise this century well below 2ºC above pre-industrial levels and to pursue efforts to limit the temperature increase even further to 1.5ºC” (ref: UN Framework Convention on Climate Change). The competitors are also asked to think of creative solutions in which chemistry can help to mitigate effects of climate change for the long term.

3. Participant Criteria

    1. This quiz is opened to all secondary school students aged 12-16 (at the point of competition).

    2. Each Team comprises of 3 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. Each team member has to participate in the speech, presenting, and answering question on the team’s topic. 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) will deliver the slide presentation, followed by a brief demonstration of the web site by Speaker 3.

          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. All teams in the finals must propose 2 DIFFERENT topics to the one spoken on in the preliminary round (see b above).

  3. Participants will design their own presentations and web sites based on the topic.

  4. 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, have their own WiFi / network data, and Mac adapter for Mac users. The team is only allowed to refer to the presentation and web site during the speech. No other props are allowed.

  5. In the preliminary rounds, the time allotted for each team will be 10 minutes. A warning will be given at the 8th minute. In the finals, the time allotted for each team will be 12 minutes. A warning will be given at the 10th minute.

  6. 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 three 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 7 minutes in the finals.

  7. The SAME three 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.

  8. The decision of the judges is final.
