When considering a working science model it is important to try and pick something that will be fun to build and to find out the result. If you think it will be a definitive result then this can make writing up the experiment easier; however you may find it more interesting if you can't predict what will happen before conducting the test.

You should always have a solid conclusion to your working science model evaluation and this should include what you may be able to improve for the next time you conduct such a test. As stated earlier, the best science models are the most interesting and fun to make, conduct and analyze; and this should be kept in mind when deciding on which to choose.
