Can families help? Families can and are encouraged to help with experiments. It is a learning process.
How long does it take to complete the scientific process? The completion time will vary upon the type of project you are doing. For example, if you are doing an experiment growing plants, it will take a much longer time than other projects. However, all projects take time. Do not wait until the last minute to begin.
Does the hypothesis have to be correct? Your hypothesis does not have to be correct. Scientists are not always able to prove their hypothesis. This is part of science.
How many variables are changed in the experiment? Be sure you are only changing 1 variable - in the example experiment only the shape of the balloon was changed. All other variables stayed the same. The track of string and straw, and number of pumps of air were not changed.
How many trials must I do? You must complete at least 3 trials, or test at least 10 people. This does not mean to test 3 different things. You need to test each variable at least 3 times. In the example experiment the round balloon was tested 3 times and the oblong balloon was tested 3 times. Also keep in mind that results in each trial should be consistent. If any trials are very different, you should redo that trial.
Can students enter as a team? Team/Group projects may not be entered. Students are welcome to work together, but each student must enter and be judged on their own. Working together does not guarantee the same results. Presentations and judges may be different.
Can I bring my experiment with me? Only presentation boards and reports will be allowed in the judging area. You cannot bring the materials of your experiment for the display or perform the experiment live. You will only be judged on your presentation and board. You can take pictures to mount on your board, but your board has to be able to stand by itself. Please do not to mount anything else on the board.
