Dissection specimens used within one year will have the best outcomes. The specimens should not be refrigerated or frozen. If the specimens will be stored for more than six months, they should be left in the supplied containers. They are individually vacuum sealed, so as long as the original seals are unbroken, the spe...
The complete reaction is: 4Cu (s) + 6H2O (l) + 2CO3 (aq) –> 2Cu2(OH)2CO3 (aq) + O2 (g) + 4H2 (g) ...

**Atwood’s Machine Demonstrates Newton’s Second Law** Sami S. Wright **Abstract** Everyone is affected by the laws of physics. Everywhere people go they accelerate, decelerate, sway, and fall. These forces are described by Newton’s Second Law which tells how objects respond to force with acceleration. In this exper...
You will need to use dried split peas or lentils for this experiment. You should not cook them beforehand since cooking or freezing ruins the DNA. ...
In the chemistry experiments, the red cabbage is used to make a pH indicator. Red cabbage can be difficult to find internationally or during the winter, so if you are unable to purchase red cabbage, the link below has a detailed procedure for using other materials to make the same indicator. [Make Your Own Indicators...
The blue substance you noticed forming on one terminal is copper hydroxycarbonate. It forms from the copper in the battery and the carbonate in the baking soda that was left over. It is the same stuff that turns copper statues (like the Statue of Liberty) a blue-green color. The chemical reaction that occurs to make ...
