Making your project look good.

An exhibit can be either a sheet of paper or card no larger than A2 (420 mm wide by 594 mm high) - this will be attached to the wall.

Three dimensional stand: its 'footprint' should be no more than 1200 mm x 750 mm with a maximum height of 900mm. The stand needs to be strong and transportable. A base will help support the sides. Corrugated cardboard or plastic can be used, or more solid materials such as particle boards.

The best size for each of the three display boards is 600 mm wide by 900 mm high Join the boards with strong tape or hinges so they can be folded for easy transport. Paint your boards in a colour that sets off the material you are displaying. Boards can be purchased from stationary supply shops.

The project can be presented as a poster.

The Scientific Method.

Research Question: The research question is the single most important part of the scientific method. Every part of your project is done to answer this question. The research question is sometimes formed as a statement and is called the "Problem" or "Problem Statement."

Hypothesis: The hypothesis is an "educated guess," formed as a statement, that you propose to be the answer to the research question. An educated guess is based on some prior knowledge.

Experimental Design: Plan an experiment in which you can test your hypothesis.

Variables: The experiment will contain an element or elements that do not change (called controlled variables or dependent variables) and elements that will change (called manipulated variables or independent variables).

Control: The control is a particular sample that is treated the same as all the rest of the samples except that it is not exposed to manipulated variables.

Observation: When you interact with your experiment, you are using your senses to observe. Does it have a smell, make a noise have colour, etc.?

Collect Data: As you observe your experiment, you will need to record the progress of your experiment. Data can be whatever you observe about your experiment that may or may not change during the time of the experimentation. Examples of data are values in pH, temperature, a measurement of growth, colour, distance, etc.

Logbook: All scientists keep a record of their observations in some form of a logbook. The logbook will begin with the date and time the experimentor collects the data. Sometimes data will include environmental values such as humidity, temperature, etc. Entries must be written clearly and with detail of description so that another scientist can read the logbook, simulate the conditions of the experiment, and repeat the experiment exactly.

Data: The data are the values written down as the experiment progresses. Examples of data entry on measuring plant growth:
11/15/04 Control Plant 7.4 mm
Test Plant 16.2 mm
Test Plant 24.9 mm
Test Plant 37.2 mm
11/22/04 Control Plant 7.8 mm
Test Plant 15.9 mm
Test Plant 23.2 mm
Test Plant 37.2 mm

Tables & Graphs: When at all possible, illustrations of data are advisable. They create a professional appearance and convey a great deal of information. Examples include: Bar Graph, Pie Chart, X & Y axis Graph, Histogram, etc.

Materials: List all supplies and equipment. Example: 250 ml. glass beaker 1 straw 150 ml. Lime Water 10 g. Baking Soda

Method: The procedure is a somewhat detailed, step - by - step description of how you conducted your experiment. Example: "After 1 minute, I stirred in the baking soda and timed the reaction to be 45 seconds."

Results: The results is usually in the form of a statement that explains or interprets the data. You do not go into any detail or explanations here. You simply say in words what your data is telling you. Example: "Test Plant 3 showed little difference in growth rate as compared to the Control Plant."

Conclusion: The conclusion is a summary of the research and the results of the experiment. This is where you answer your research question. You make a statement of whether your data supported your hypothesis or not. You may have data that supported part of your hypothesis and not another part. You may also have data that did not support your hypothesis at all. In this case, you may explain why the results were different.

Application: The application is how the information or knowledge gained in the experiment can be used. It is not often included in science fair projects.

Resources: One of the most important things for a student to do is recognise the people and resources used in developing and conducting the project. Name the people who offered knowledge or helped, and list the web sites, retail stores, magazines, books, computer programs, etc. that were used as sources of information or supplies.

Ethics Information

Projects involving animals

For projects involving animals it is important to get ethics approval beforehand if necessary. Retrospective approvals will not be given so if you are unsure please seek ethics approval.

Ethics approval for Science Fair projects in New Zealand is managed by the New Zealand Schools' Animal Ethics Committee: https://animalethics.org.nz/

> Informations on when you need to complete an application and how to complete an application are available on their website. If your application is approved you will be sent approval stickers by the committee - please attach these to your board at the fair so that we know it has been approved.

    Projects involving humans

    Projects involving humans could involve the following:
  • Tasting, touching or smelling different foods or other substances

  • Taking any medicines, drugs or other substances

  • Applying any substance to their bodies

  • Undergoing any physical or medical tests

  • Giving you any information of a personal, private of confidential nature

  • Giving information that could identify them

  • For projects involving humans, ethical approval is NOT required.

    However, the following guidelines must be followed
  • Safety of everyone concerned must be paramount.

  • Any project should only involve minimal risk ie any adverse effect should be very small, and the probability of that effect occurring should be low. For instance, if one is asking people for information, it should only be the sort of information it would be safe, easily volunteered and appropriate to ask in an ordinary conversation, or if you are asking people to exert themselves, physically it should only be to a level that that person might do in everyday life.

  • When people are asked to participate in research, they need to be told clearly what the research is and what they will be required of them. If you are collecting information from them they need to know what will be done with that information, who else will see it and whether or not the information can be linked to a particular person.

  • If your research involves no unusual risk or exertion or unreasonable request and the person can’t be identified, then no written permission is necessary. Otherwise, written permission must be obtained from the person and the person’s guardian if under the age of 16.
