SCS Sensory Info (Scientist For A Day Exhibition)




Be a scientist for a day at our discover-it-yourself laboratory! Move through the stages of the Scientific Method guided by our facilitators, volunteers and, when available, guest scientists.



Paper Chromatography

Stain a piece of chromatographic paper with coloured mixtures near one edge. “Stand” the paper upright, dipping the stained edge into some water. Each colour advances up the paper at a different speed, thereby separating out from the mixture!


Plasma Ball

Discover Tesla’s incredible Plasma ball - a clear glass device filled with noble gases with a high-voltage electrode at its centre! Place your fingertips on the ball (one at a time) and watch how the pretty glow of discharges appear to connect with them! It’s an electrifying spectacle at your fingertips.

How to get the most out of Scientist For a Day

You can enjoy Scientist For A Day on your own or with your family. We also welcome school groups. The exhibition is open to all visitors during the Science Centre's regular opening hours. However, the DIY Lab and its facilitators are only available at set sessions.

• Morning session: 10:00 – 12:30
• Afternoon session: 14:00 – 16:30

For school-class or large group visits, other DIY Lab time slots can be pre-arranged through advanced booking only. More details are available here.

Accompanying adults are strongly advised to remain with their students or children to assist in and support their learning.

The Scientific Method

At school we learn about the ‘Scientific Method’ – use our lab to put it into practice.

The Scientific Method is a flexible process – a set of principles and procedures for the systematic pursuit of knowledge, involving the recognition and formulation of a problem, the collection of data through observation and experiment, and the formulation and testing of hypotheses. 

It systematically engages one’s senses on an intriguing or enigmatic idea and uses our pre-knowledge, ingenuity and creativity to understand and resolve it – all in a methodical, analytical-logical manner.

Using the Scientific Method

Our facilitators will lead you through various simple but thought-provoking experiments using "inquiry-based" methods. This helps you to understand the scientific concepts underlying the experiments and familiarises you with the Scientific Method. 

Steps of the Scientific Method:

  1. observe a phenomenon
  2. frame the problem/question(s)
  3. list the salient variables 
  4. hypothesise an explanation linking the relevant variables
  5. design the experiment
  6. collect data
  7. discuss the results
  8. conclude on your hypothesis
  • Featured Experiments

    When in attendance, the DIY Lab facilitator(s) will set up some of the following experiments:

    • Static Electricity & the Van de Graaff Generator

    Please note the following:

    • Access to the exhibition may be restricted during DIY Lab classes and/or other special events.
    • Under certain circumstances, our DIY Lab facilitator(s) may be called away for other duties at short notice and the DIY Lab session will be suspended. We sincerely apologise for any inconvenience caused by such instances. Updates will be provided at the Lab and/or through public announcements, when applicable.
    • Each experiment usually requires not more than 10 minutes. You are welcome to stay and ask questions after the experiment is completed.
    • You may join in any experiment at any time, on a first-come, first-served basis.  
    • You are free to learn at your own pace at the experiment stations and you are not obliged to complete any particular experiment or work through all the experiments on offer during that session. 
    • All interactions and activities, are conducted in English only.
    • Not more than three or four experiments can be simultaneously set up in any one session. It is not possible to showcase all the experiments listed above at the same time in any one session.  We seek your understanding and cooperation as we will not be able to accept requests for specific experiments.
    • Our facilitators will receive one inquirer at a time, on a first-come, first-served basis, and will accommodate as many participants as possible.
    • The Scientist For A Day Exhibition and its interactivity are also a "Public Learning Destination" of Children's University Singapore (CUS). CUS members must identify themselves to our facilitators before the start of their interaction. Once your learning activity is completed, please provide your CUS Passport for endorsement. Please note that such requests are only available during the daily sessions.

  • Visitor Etiquette
    • Please respect our DIY Lab facilitators and our exhibition so that we can provide an enriching learning experience for all visitors. 
    • When there is more than one visitor in the Lab, our facilitators may answer your question(s) (perhaps, with more thinking questions), then move on to the next visitor's queries. Your understanding and co-operation are much appreciated, especially during the more crowded sessions. 
    • Abusive and disruptive visitors will be asked to leave the Lab. Please view the Science Centre's Service Charter.
    • Please accompany your children at all times. Your presence adds to their learning experience and their safety.

For Schools or Large Groups

We welcome school and group participants to the Scientist For A Day Exhibition and its DIY Lab. Give your students hands-on practice in the Scientific Method!  

Each DIY Lab Session for schools or groups can take a maximum of 30 students, is 90 to 120 minutes long, and must fit within our sessions:

  • Morning session: earliest start time is 10:00, latest start time is 11:00
  • Afternoon session: earliest start time is 14:00, latest start time is 15:30

The Lab Session

Students will carry out a simple experiment using the Scientific Method.

  • Tour and other groups must book their session through our Corporate Sales team. We will contact you to finalise your choice of the experiment.

The choice of experiments are:

  • Timing with a Pendulum: how did Galileo measure the time of fall in his Tower of Pisa experiments? Remember that he didn't have smartphones with stopwatches!
  • Hooke's Law on Bungee Jumping: if you start a bungee-jumping business with only one bungee cord, how can it cater to the different sizes and weights of your customers?
  • Follow the Bouncing Ball: watch the bouncing ball rise and fall, and rise and find out why it always follows a pattern. What are the controlling factors?
  • Parallel and Series Circuits: which is brighter or better – bulbs in parallel or bulbs in series?
  • Centre of Gravity Balancing Act: learn about centre of gravity (CG), how to find the CG of anybody and ideas on equilibrium and stability. Where is the CG of a tightrope/high-wire walker/funambulist? How do they keep their balance?

The DIY Lab Session Programme includes: 

  1. A summary tour of selected exhibits and introduction to the Scientific Method (15 minutes)
  2. A briefing-demonstration of your pre-selected experiment – realising your observational skills (15 minutes)
  3. Conducting your experiment with facilitation, pre-planning required (60 minutes)
  4. Discussing and concluding – which is better, an incorrect hypothesis or a not-wrong hypothesis? (15 minutes)
  • Terms and Conditions
    • All interactions and handouts are in English only.
    • Each DIY Lab session is 90-120 minutes long.
    • Each DIY Lab session can take a maximum of 30 students.
    • Bigger classes/groups should be divided into smaller groups and "rotated" sequentially through consecutive DIY Lab sessions. While one group (of fewer than 30 students) is at the DIY Lab, the other group(s) can be engaged in other enrichment activities throughout the Science Centre. Please check the Online Booking System (OBS) or with School Services for our many enrichment programmes and gallery pathways and their availability. 
    • Large groups may need to stay longer at the Science Centre in order to rotate all the smaller groups through their DIY Lab sessions. (To avoid putting unnecessary time pressure on the sub-groups, do consider dividing the group to visit on different days.)
  • Advance Booking Required
    • Advance booking is mandatory and on a first-come, first-served basis. We are not able to entertain walk-in groups and we are not able to cancel or reassign facilitators from pre-announced public interaction sessions to accommodate impromptu requests.
    • Schools that are Science Centre members must make their bookings through our Online Booking System (OBS). Please note all the terms and conditions of using the OBS. 
    • Please indicate your preferred date and time of day (within the limits of the terms and conditions). OBS will send an acknowledgement of your booking request. Final confirmation will depend on facilitator availability as well as other priority uses of the exhibition space. Our facilitators may also contact you for more information on your students and your requirements.
