Science Experiment/ Report help
Posted: Thu May 08, 2008 8:24 am
Please Help! I am working on a Science Experiment/Report, and I decided to do the experiment Dog Toys:What makes One Favorite or a Flop to Fido?-That was listed on Science Buddies. My problem is that I can't figure out what the varibles are? Independent variable? Dependent variable? Controlled variable? Science buddies suggest that you conduct 4 experiments and 3 trials per experiment. You will use 4 dog toys per experiment-and continuing to use the same toys for each of the trials per experiment. I think that my dog-Harley would be the dependent variable(because he won't change), But what is the independent variable? I think that the independent variable would be the different type of toys used for each experiment, interactive toys, different shaped toys, different textured toys, favorite four-but how would that be worded? Various toys? Would various toys be the independent variable? Humm....not at all sure about controlled variable-maybe the location of the test-my living room, Harley-my dog, and maybe the same number of toys? I'm also not sure about how to measure this either. I am thinking that the nominal data (qualitative) collected in these experiments will determine which one of the dog toys will ultimately stimulate Harley the most. Any input would be greatly appreciated!
