You have to see Megan’s award winning science fair project ideas for 8th graders.
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.
- Even number of men and women subjects
- Different bathrooms around town – Wal-Mart, Restaurants, Fast-food places, Gas Stations etc.
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.

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.
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.

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.

Paper Cups to collect Soil Samples
Project #6 –LET THERE LIGHT
Ideas – Earth Science Fair Projects
Problem – If you take a piece of cardboard and cut different shaped holes, what image will the sunlight produce when it shines through these different shaped holes?
Hypothesis – I believe that the image will take on the shape of the cut out.
Project #7 – PROPORTIONAL PARTS
Ideas – Biology – Life Science – Human Anatomy
Problem – Is there any proportional relationship between the circumference of one’s head and the length of one’s foot?
Hypothesis – I believe that there is a proportional consistency between the circumference of one’s head and the length of one’s foot.
Project #8 – A GLOWING LIFE
Ideas – Chemistry – Glow Stick
Problem- Is it possible to extend the life of a glow stick using various methods such as heating it, refrigerating it, freezing it or placing it in a vacuum?
Hypothesis – I believe that the life of a glow stick will be extended by cooling it; therefore, refrigerating and freezing will be the best methods.
Refrigerator and Freezer
Project #9 – CRAZY ANTS
Biology – Zoology – Ants Behavior
Problem – Do ants get dizzy? Are ants affected by circular movement?
Hypothesis – I don’t believe that ants will become dizzy because they don’t have an inner ear which in humans affects one’s balance.

Project #10 – THROUGH THE EYE OF A CAMERA
Ideas – Chemistry – Photography Science Fair Projects
Problem – Can near-infrared photography be used to find the best building materials for a house?
Hypothesis – I believe that because near-infrared photography shows how much near infrared rays are reflected or absorbed, I will be able to tell which building materials reflect the most near-infrared rays and therefore be able to choose building materials that would absorb less of the sun’s rays.
