A. What we know: We were trying to find out what our favorite pets are.  We know that people own pets. B. What are our assumptions: We assumed we would get results back from our survey. We assumed that the three most popular pets, would be the ones that got the most votes. We assumed that the most unpopular pets, would be the ones that got the least votes. C. What we did: We made up a survey. The survey asked: What your favorite pet is? What pets you owned? If that was your favorite pet? We gave the survey to all of the students of the Miller Avenue school. We gave out about 400 surveys. We got back 222 surveys.  We sorted the surveys into groups. We counted how many there were in each group. We rejected 36 surveys because they didn’t make any sense, or they had more than one favorite. We typed the results on a spreadsheet. After that we graphed them. Here’s the results: anoles 1 birds 6 fish 3 crayfish 2 bull 1 frog 1 elephant 1 ferrets 1 gorilla 1 guinea pig 4 hermit crab 1 horse 1 jaguar 1 lizard 4 mice 2 monkey 1 hamster 6 hedgehog 1 pet rock 0 praying mantis 1 rabbit 4 snake 2 turtles 7 dogs 99 cats 29 none 6 D. What we found out: The three most popular pets are dog, cat, & turtle If we were running a pet store we would sell food for dogs, cats, turtles, birds, hamsters, guinea pigs, lizards, rabbits and fish. The reason is that they are the most popular pets.  The most unpopular pet to own is a pet rock, because if you start playing with it you could get hurt, it’s not living and it is no fun at all.  I own two pets, both are cats, male and female. They are one of the popular pets.  E. What do you do next: Do a follow-up survey to determine why people have those kinds of pets.

1. We began the case of the most popular pet with a meeting of all the pet detectives. We made a list of all the animals we could think of that could be pets. We also left a blank line for people to write a pet in if we forgot to name it. Then we made a list of the 7 continents of the world. We crossed Anartica off because it is too cold for people to live there.

2. We decided to ask people to name their favorite pet and tell what continent they were from to find out what pet was the most popular in all the world. We typed our questions into the personal publisher program and made a web page at http://members.aol.com/chteach1/pdet.html. We put our survey questions on our page with our e-mail address. We got many responses and we loved to hear "You have mail!". We worked in pairs. One person read the email and the other person wrote down the animal and the continent on our case clues sheet.

3. Our mail was slow, so we decided to print out the survey questions and pass them out to the students in our school. We used our pairs to record the answers from our friends. We went to a keypal page and sent letters to people from other schools in other continents to ask them our questions. We made some new friends and got some answers! Then we asked our teacher to ask her friends on-line to visit our page. We ended up with 214 different people taking our survey.
