Some topics that I have considered doing:

1. Something to do with Environmental Science e.g:

• Whether air pollution varies during the week and if so, how much.
• Investigations of relations between C02 and warmer temperatures (global warming)
• How organisms respond to changes in the environment
• The effect of trash and garbage on the environment
• Which method is the most effective for treating water for chemicals, heavy metals and bacteria?

2. Something to do with Earth Science e.g:

• Does the amount of moisture in the atmosphere vary from place to place?
• How soil management affects soil quality
• What causes landslides
• Why the ocean is salty
• Whether the depth of the ocean affects its temperature

3. Something to do with Medicine or Health e.g

• Which Apple Type Changes in Sugar Content Most After Removal From Cold Storage?
• The Effect of Gatorade Vs. Water on a Teenager's Pulse Rate while Exercising
• The Effect of Shampoos on the Tensile Strength of Hair
• How effective is sunscreen in undercover makeup or moisturizers versus regular sunscreen?

Or Just some Miscellaneous ones e.g:

• Effectiveness of Blu Tack on holding up a poster in hot dry conditions
• What conditions keep a balloon maximally inflated for the longest period of time?
• How good are we at hearing one voice in the crowd?
• Eyes and the ability to judge distances
• Eggshell strength and organic eggs
• Design an effective smoke alarm for the deaf
