Saahil Science Fair Project Saahil Science Fair Project Presentation Transcript

  • Saahil Aneja M.I.T. (Minto’s Institute of Technology) Farmington Hills, Mar.12th 2010 Strictly Confidential – ‘Top Secret’ Clearance including Retinal Scan Required for Access Confidential Research
  • PROBLEM
    • Why do objects sink or float in water?
    • Can an egg float in water?
  • HYPOTHESIS
    • Objects sink or float depending on their density and buoyancy .
    • An egg can float in salt water.
  • PROCEDURE
    • Fill a glass ¾ full of water.
    • Carefully place an egg in the water. Observe and record results.
    • Remove the egg from the water. Add 2 tablespoons of salt in the water. Stir well.
    • Carefully place the egg in the water. Observe and record results.
    • Repeat steps 3 and 4 till the observation changes.
  • RESULTS - 1
    • The egg sinks in ‘plain’ water.
  • RESULTS - 2
    • The egg floats in salt water.
  • KEY LEARNINGS
    • Hypothesis confirmed.
    • Density : How heavy something is for its size . 
    • Buoyancy : The force that causes something to float .
  • DID YOU KNOW?
    • The buoyancy principle was accidentally discovered 2200 years ago by the Greek inventor and mathematician, Archimedes, while he was taking a bath.
    • Archimedes was so excited with his discovery that he hopped out of the bath, and rushed naked into the street yelling triumphantly, 'Eureka!' 'Eureka!' (Greek word for 'I have found it!’).
