The Connected Chemistry Curriculum You can put the ConnectedChemistry.jar file anywhere on your hard drive, whether on your desktop, an apps folder, or another directory. However, if you're having trouble, put this file alone in a folder by itself, so other, older files don't interfere. If you attempt to launch the ConnectedChemistry.jar file directly from a CD, the Simulation will not work. The ConnChem Simulations actually require two files to run: ConnectedChemistry.jar chemdb If you don't have the second file, don't panic: when you run the "ConnectedChemistry.jar" file, it will create the "chemdb" file in the same folder for you. I fact, when you download the software, it's best if you delete any files named chemdb you can find. Do not rename any files. To run the software, follow these steps exactly create a new folder on your desktop, named whatever you like (ConnChem is a good choice) drag the file ConnectedChemistry.jar into your new folder. What should I do if my simulation window is flashing?

Now, you will pour each liquid SLOWLY into the container, one at a time. It is very important to pour the liquids slowly and into the center of the cylinder. Make sure that the liquids do not touch the sides of the cylinder while you are pouring. The same amount of two different liquids will have different weights because they have different masses. To test this, you might want to set up a scale and measure each of the liquids that you poured into your column. Density is basically how much "stuff" is smashed into a particular area... or a comparison between an object's mass and volume. The same goes for the small objects that you dropped into your density column. In the materials, we had you grab a bunch of miscellaneous tiny objects. When all the liquids and small objects have been added to your density tower, you will have what appears to be a magic column. Why do you think these two phenomena happen?
