TITLE: (Kathryn 4/5/11) Rate Of The //Eisenia foetida// Growth.
=Background=

**Research:(Danyi 3/12/11)**
source: [] Food of **Feed Worms:** source: [] Temperture: The place for the worm bin should be where the temperature ranges from 55 to 77 degrees Fahrenheit (13-25 degrees Celsius). Temperatures below freezing and above 80 degrees Fahrenheit (26 degrees Celsius) can harm the worms. =**Purpose:(Danyi 3/12/11)**= To see how many worms are in the bin. The independant variable for this worm lab is an atempt to change the amount of worms foud in our worm population. We will due so by playing around with the amount of food we feed the worms. The dependant variable for this worm lab is how much food we will feed our worms.(50.0 grams)
 * Bedding and Moisture:** The function of a worm bin is not only to provide darkness for your compost worms but also to conserve the moisture. And also allowing excess moisture to drain. Peat moss works especially well for retaining moisture in dry climates.
 * Vegetable scraps
 * Fruit scraps and peels (mold/rot is fine)
 * Bread and grains
 * Teabags
 * Non-greasy leftovers
 * Coffee grounds (and filters)
 * Crushed egg shells
 * Napkins, paper towels
 * Don’t Feed**
 * Don't overfeed citrus—should be no more than 1/5 of worm food
 * Meats, fish
 * Greasy foods
 * Dairy products
 * Twigs and branches
 * Dog/cat feces, cat litter
 * Variables:**

The hypothisis for this worm lab is to see if we can increase our worm population from 150 worms to 190 worms. We want to do so by feeding the worms about 50.0 grams of worm food for each week. And you can see if we were sucsesful or not if you look at our conclusions at the bottom of this worm lab experament.
 * Hypothisis:**

**materials:(Sunny 3/5/11) bins, wet newspapers, foods, moisture, soil,**

 * Procedures: We keep out worms in a bin with wte, shredded news paper. We feed out worms 50 grams at least once a week. The worms should eat egg shells the most because it is good for them. We need to bury the food, also (Bailey 3-5-11)**

=Conclusion: Nathan (4/3/11)= In our hypothesis we guessed that our worm population would grow from 190 worms to 250 worms. We realized that if we feed the worms regularly that they will grow. In other experiments we had not fed at all, or we had fed the worms irregularly. This time we fed them roughly 50 grams per week and the population increased by about 130 worms. We conclude that if the worms are fed regularly and are in a good moist environment that the population will definitely increase.
