A Balloon Applet, with moving gas molecules, thermometer, and
pressure gauge
This applet takes a while to download all its parts, and more time before the applet starts running. The balloon and the gas molecules are encountered individually as images. It would be better to encounter them as a composite graphic, balloon with gas molecules. Instead of the image number (which can change ) it would be better to be given an image name.
In the same manner, the parts of the thermometer are encountered with no basis for relating them to each other. The temperature text and image number are encountered on different lines, obscuring their spatial relationship. The thermometer could be encountered as a composite object. The object could be moved about on before moving on to the next line or object.
The pressure gauge has a TextField to display the graphic information, but it is unclear what the TextField contains when it is encountered in the line by line reading. The spatial relationship between the text pressure, the image of the pressure gauge (and what the gauge image represents) is lost.
