Our Very Own Mini Exhibition!

Two weeks prior to our 7th meeting, the members were given a brief description about the activity that would be held in a fortnight's time. A mini exhibition was to be held and members were assigned to invent their own experiments or at least exhibit something out of the ordinary. They were given two weeks to prepare their idea and to handle the paperwork. Materials and chemicals that were needed were provided by the school lab and members were required to bring their own apparatus. 4 groups were created and as weeks passed by, it was time for our mini exhibition. 
Preparations were made and the members settled in. The panel of judges for the day were the Pn.Chuah, our teacher advisor and the board of directors. Members were really committed in preparing the exhibits and their final product was equally as good as well. It's time to let the pictures do the talking.

Food colouring and milk? This ought to be interesting.

They make the atmosphere so cheerful as they'e always smiling.

Golf ball with glue. Now that begs an answer.

Some nice fancy coloured solutions. 

Packed and ready to demonstrate their exhibit I should say.

And yes that's what they did. They were the first group to show their work  as the judges started the mini exhibition.

Ever heard of spinach being an indicator for acidic and alkaline solutions? Well that's what they did. Boil some spinach and crush them into pieces. A spinach solution is formed.

After testing different types of solutions, it's found that acidic solutions turn the indicator red while alkaline solutions turn the indicator blue.

Next, we have colour changing milk. 

Now I see the relation between food colouring and colour changing milk.

It's an explosion of colour!

Start with a dark colour.

Then add a few more colours into the mix.

Observe how the colours disperse around in symmetrical patterns of wave. It really is an explosion of colour! 

The crowd gathers to watch the demonstration along with the judges.

A friction compensated runaway. The ramp is angled in such a way that the rolling ball  stays static.

Pn.Chuah discussing the uses and benefits about their experiments with the members

Niroshen briefly explaining the use of his experiment along with his partner.

His experiment exploited the concept of invincibility. Transparent ink  that can only be decoded with white light or monochromatic light. Innovative.

After evaluating and deciding the best group with the best experiment, the panel of judges announced their results.

The runner-up of the day's best experiment goes to colour changing milk. Geraldine Lim and Shane Lopez received a prize for their efforts. 

And the mini exhibition's best group goes to...

NurNatasha, Norman and Su Jean for their spinach as an indicator solution. Congrats to them!

All in all, this week's activity was to expose members to the wonders of science. Experiments of all sorts were carried out by members to encourage a positive and scientific mind as well as innovation and creativeness. A job well done.
