Colorful Convection Currents !


Articles Required : Three tablets of water colours, hard-glass jar.

When you heat water, only a part of it comes into a direct contact with its container which is being heated. But strangely enough, the tempera­ture of entire body of water rises uniformly. So, it means that the heat absorbed by the container spreads equally throughout the entire liquid. The most interesting fact about it is that this process of heating is not haphazard and takes place in a very systematic manner. You can witness it through the experiment explained below:

Fill three-fourths of glass jar with water. Drop small pieces of water-colour tablets into it. Now you'll notice that as this water gets heated, coloured currents emerge from the tablet pieces and come down almost touching the container walls in the form of a foun­tain. Do you know why it happens like this? As the water at the bot­tom gets heated, it becomes lighter and rises upwards. It makes a place for itself at the top displacing the water present there. The water at the top is cool and thus heavy. As a result, it sinks down and fills the gap left by the hot water. This process goes on like this.The particles of colour tablets (red, blue and green) that you have dropped into the water, become a part of the water current after dis-olving in it. They form a definite pattern with the convection currents and you can notice a pretty colour­ful fountain inside the glass jar.

Fire Water Balloon

Materials The materials required for this science fair project: - 1 matchbox - 1 candle - 1 yellow colored balloon - 1 blue colored balloon - Half a cup of water Procedure 1. For this experiment, the independent variable is whether the balloon is filled with water or not. The dependent variable is what happens to the balloon when it is placed above the lit candle. This is determined by observing the balloon. The constants (control variables) are how much the balloon is inflated and the amount of water in the balloon. 2. Inflate the yellow colored balloon and tie it up. 3. Pour half a cup of water into the blue colored balloon before inflating it to the same size as the yellow color balloon and tie it up. 4. Light up the candle. Be careful when using match sticks to avoid causing fires, or burning yourself. 5. Hold the yellow colored balloon on top of the lit candle. Observe and record what happens. 6. Hold the blue colored balloon on top of
