My Ant Universe (continued)

Hi is so long that I have not update my blog on my ant universe. Actually my ants have died long ago. I think they can only survive for 2 weeks, slowly their movement become slower and died. This is the final master piece of my ants universe that is created by the ants I caught.

My Ant Universe

I saw this Ant Universe online and was interested to buy it and rear ants. It is a plastic flat aquarium with blue colour gel. To my surprize, I actually saw it at the souvenir shop in Science Centre and it cost SGD 30. So I quickly bought it to create my own ant universe.

Catching ants is a challenge as you need to be fast to keep it in a small container. However putting the ants in the aquarium is even more challenging, as once you put 1 in another will escape. So I decided to put a clear plastic tube as a passageway for the ants to travel in. At least with that, it slow down the ants from inside to escape as it needs time to travel through the passage way and before they can move to the exit we have already closed the exit.

So have a look at the aquarium at Day 1 when we just put in the ants (you can see the passageway is still there, as some ants still stay in the passageway so I cannot remove it till Day 3 when the ants are all in the aquarium.

Forgot to mention that the ant universe is not for rearing ants only, the interesting part is to see how they dig tunnel, so you can actually see my pic on Day 3 has tunnel dig by the ants already. Soon the whole aquarium will have a network of tunnels.

The Final Version of the Poly Density Bottle

Hi, just want to update that my student have come out with the design of the poly density bottle (with the help of their mentor). To make it interesting, they actually made 4 bottles with a theme of four season. So each bottle the colour of the plastic is link with either Spring, Summer, Autumn or Winter. Behind each bottle, the students also pasted pictures from magazine to suit its theme.

What I am proud of them is that, the group win a special mentioned prize, as the judges say it is very creative and is also look like an artistic piece that shows a science theory. Even though they are not the top 3, however the other winner are from Raffles Institute and Hwa Chong which are those top schools of Singapore, so we are really proud to win that prize.

The theory is still the same, once shake, the density of the mixture will cause 1 kind of plastic to sink another type will sink. However once the propanol and salt water is separated, the float plastic will sink to the middle and the sink plastic will float to the middle. Now have a look at their final version.
