Making a good science fair project GREAT!

Posted by on October 30, 2011

The key to a great science fair project is designing it yourself. I hope this website helps you do just that. If you are still having trouble finding an idea, start with what you know you can measure. Do you have a stop watch? a ruler? a thermometer? a scale? Think about all the things you can measure:

For your DEPENDENT VARIABLE (needs to be quantitative), you could measure…
• size or a change in size: weight, height, length, volume, area, perimeter, diameter
• speed (= distance / time)
• concentration (= # / volume)
• density (= mass/volume)
• frequency (how often something happens)
• angles and/or direction
• percent coverage, percent change (loss or increase)
• and many other things like temperature, humidity, light, sound, pH, wind speed, direction, water quality, tidal height, heart rate, blood pressure, reaction time

The INDEPENDENT VARIABLE can be either quantitative or qualitative (if you need help with the definitions of these words – see “words you need” page).

Examples of qualitative variables would include:
• color: red, blue, green, yellow, orange
• male/female
• small, medium, large
• slow, medium, fast
• high, low
• old, young
• labels for groupings: A, B, C, D, E
• any type of category

Be creative, remember my formula for success (under “getting started”)
