Does the size of an aquarium determine how large the fish will grow?


 * INCLUDE ALL OF THE FOLLOWING WITH YOUR EXPERIMENTAL DESIGN: **
 * [remember it must be a controlled experiment] **
 * 1. A hypothesis: **
 * An aquarium's size will not determine how large the fish will grow.
 * 2. Explain how to set up the experiment: **
 * To set up this experiment, get a total 40 fish.
 * Then get 4 aquariums.
 * Seperate the 40 fish into groups of 10.
 * Put each group of 10 in a aquarium.
 * The 4 aquariums will be different sizes.
 * One aquarium will be small.
 * Another aquarium will be medium or normal sized.
 * Also, an aquarium will be large.
 * Last, an aquarium will be extra large sized.
 * Every fish will be brought to the aquariums at the same age.
 * Each fish will be the same type.
 * They will live in their respective tanks for a total time period of 2 months.
 * === After 2 months, the fish will be examined in their aquarium to see which aquarium of fish has grown the largest. ===
 * Brainstorm a list of all the variables that must be kept constant during the experiment: **
 * how much you feed the fish
 * brand of fish food
 * quality of water
 * brand of aquarium
 * type of fish
 * condition of the tank
 * type of water (salt or fresh)
 * quality of fish food
 * temperature of the water
 * age of fish when first put in aquarium
 * health of fish before experiment
 * Include identification of the independent variable: **
 * The sizes of the four different aquariums
 * The dependent variable: **
 * The different fish in the aquariums.
 * Identify the control group: **
 * The fish in the normal sized aquarium
 * Identify the experimental group(s): **
 * The 3 other groups of fish in the other aquariums
