Project #1 – WHICH WASHES?
Ideas – Biology – Human Psychology – Science Fair Projects: Hand Washing

Problem – Hand washing is important; but who is cleaner, men or women? Who washes their hands the most, men or women?

Hypothesis – I believe that women will tend to wash their hands more so then men because they prepare food and change diapers, on the average, more often than men.

Materials –

  • Even number of men and women subjects
  • Different bathrooms around town – Wal-Mart, Restaurants, Fast-food places, Gas Stations etc.
  • Notebook
  • Pen

Project #2 – NESTLE CRUNCH BAR VERSES CAPTAIN CRUNCH
Ideas – Health & Medicine – Food Science Fair Projects – Nutrition – Sugar in Candy Bars

Problem – Which has more sugar per ounce, your cereal or your candy bar?

Hypothesis – I believe that even though your cereals do contain sugar, the candy bar will still have more.

Materials –
A variety of candy bars
A variety of cereal
Notebook
Pen

Project #3 – BREAKFAST: WORTH ITS WEIGHT IN GOLD?
Ideas – Consumer Science – Brand Name Cereals vs Steak & Eggs

Problem – Ounce for ounce which costs more, brand name cereals or steak and eggs?

Hypothesis – I believe that the cereal will be more expensive because they don’t weigh as much as the steak and eggs but still seem to cost as much.

Materials –
Variety of brand name cereals
Prices and weight of steak
Prices of eggs

Project #4 – GOOD VIBRATIONS
Ideas – Biology – Zoology Science Fair Projects – Worms – Behavior

Problem – Do you find worms closer to busy highways or further away?

Hypothesis – I believe that the vibrations from the traffic on busy highways will affect the population of the worms and cause them to move further away from the busy highways. Therefore, the density of the worm population will lessen as it gets closer to busy highways.

Materials –
Busy Highways
Adult supervision
Reflective vest
Shovel
Plastic bag to be used as a capture mat
Notebook
Pen
Tape Measure

Project #5 – POWER PACKED PUNCH
Ideas – Biology – Botany – Weather – Nitrogen Science Fair Projects

Problem – Will the nitrogen in the in the soil change after a major thunder storm?

Hypothesis – Since lightening is a major Nitrate producer, I believe that the nitrate levels will be higher in soil after a thunderstorm.

Materials –
Nitrogen test kit
Soil samples
Major Lightening Storm
Shovel
Measuring Tape
Paper Cups to collect Soil Samples
Notebook
Pen
