Cardboard Challenge by Annika and Trisha-IV E and B

Our school initiated the Cardboard Challenge to encourage our creativity and thinking process. Each of us was asked to make something out of Cardboard. Since our current UOI Topic is Energy, we were asked to add some form of Energy to our cardboard challenge.

My friend Trisha (From 4E) and I decided to team up for the challenge. Since our topic was Energy, we decided to add Electric Energy to our cardboard. Initially we just created sound and light on a cardboard. When our Moms told us to think outside the box, Trisha and I put our brains together and decided to make a Birthday Cake with an Electric Candle that sings Happy Birthday in 2-different tunes.

The birthday cake itself was fully made out of cardboard. We made it look like a 3-Tiered cake where each tier is decorated in a different theme with sprinkles, stars and patterns. The electric candle that lights and plays the tunes is run on Electrical Energy driven by a circuit. The circuit has 4 main parts:

1.  The Battery

2.  The Switch

3.  The Speaker 

4. Built-in circuit with music tones

While the Electric Cake turned out to be very good in the end, we ran into problems while creating it: problems such as the speaker falling off, battery not working etc. We both put our brains together to figure out the solutions to these problems---some simple enough that pressing down on the pieces fixed; for others, we had to rebuild to fix the problems.

If there is one thing we could have done, we feel we should have made it a bit brighter and colorful.

Trisha and I are very proud of ourselves because we worked as a Team and also because we did something that a lot of other kids may not have thought of. But we feel that everyone’s is the best.
