**GREEN STAR POLYPS LAB **
 **BACKGROUND INFORMATION- Scientific Name**:**//Clavularia viridis//** Common Names:****Green Star Polyps**  Green Star Polyps will tolerate fairly low light levels, but tend to develop brighter colors under higher intensity lighting. If the lighting is lower then the polyp will probably become a lighter green color. they grow fairly quickly and tend to cling to surfaces such as glass and rocks, sometimes leaving a nice backdrop in a tank. their polyps come out durring the day and close durring the night or when disturbed. they are a collonial coral, with each polyp having 8 tenticles. in the wild, some green star polyps reproduce sexually, whille most tank varieties budd to reproduce. these corals also host the bacteria Zooxantlellae, which enables them to get most of their nutrition through photosynthesis.
 * Classification**:**Soft Coral
 * //Temperature:74° to 82°f//**

 * //Water Flow: Medium//** 

**PROPAGATION-** Propagating Green star polyps is very simple. The green polyps grow on a purple mat. Simply cut the mat into however many pieces you need and you're all set.

 **INTRODUCTION-** Our Group is doing an experiment about the growth of Green Star polyps in home kept tanks. we will be testing the impact of different levels of light on the growth of the polyps. in order to do this, we will be using several tanks (connected by one single filter system) with each one getting a different amount of or kind of light source.


 * MATERIALS- **


 * rubber gloves
 * green star polyps
 * 4 cement plugs
 * scissors
 * Reef Glue (though really, any super glue will work just fine.)
 * Fish tanks
 * <span style="background-color: #ffffff; color: #0f850f; font-family: 'Comic Sans MS',cursive;">Lights of different light wattages.

 * <span style="background-color: #ffffff; color: #008000; display: block; font-family: 'Comic Sans MS',cursive; text-align: left;">PROCEDURE- **<span style="background-color: #ffffff; color: #008000; display: block; font-family: 'Comic Sans MS',cursive; text-align: left;">
 * 1) <span style="background-color: #ffffff; color: #008000; display: block; font-family: 'Comic Sans MS',cursive; text-align: left;">Gather materials listed above
 * 2) <span style="background-color: #ffffff; color: #008000; display: block; font-family: 'Comic Sans MS',cursive; text-align: left;">Put on your gloves
 * 3) <span style="background-color: #ffffff; color: #008000; display: block; font-family: 'Comic Sans MS',cursive; text-align: left;">First cut your piece of Green Star Polyps into 4 pieces, trying to keep them as close to the same size as possible.
 * 4) <span style="background-color: #ffffff; color: #008000; display: block; font-family: 'Comic Sans MS',cursive; text-align: left;">Use the Reef Glue to attach the polyps onto the cement plugs. (remember to be careful not to glue the tops down, as the green tenticles will retreat when it is touched, making it extremely difficult to tell the difference between the top and bottom of the polyp )
 * 5) <span style="background-color: #ffffff; color: #008000; display: block; font-family: 'Comic Sans MS',cursive; text-align: left;">Take the finished product and place them in different areas of the tank, each receiving a different amount of light.
 * 6) <span style="background-color: #ffffff; color: #008000; display: block; font-family: 'Comic Sans MS',cursive; text-align: left;">Watch the Green Star Polyps over the next 5 or 6 months and record any growth or color change.
