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”)
Hi and thanks for finding the time to describe the terminlogy to the rookies!
Many thanks for taking the time to describe the terminlogy to the noobs!
