KENTUCKY (May 28th - June 3rd Hooked on Science - Salty Egg)

INGREDIENTS

• 2 Clear Plastic Cups
• Water
• Salt
• 2 Uncooked Eggs
• Digital Scale

INSTRUCTIONS

STEP 1: Fill the one of the clear plastic cups half of the way with
water. Describe and classify the water by its observable properties.
Using the digital scale, determine the mass of the water.
STEP 2: Place an uncooked egg into the water. Does the egg sink
or float?
STEP 3: Fill the other clear plastic cup half of the way with water.
Add half a cup of salt to the water and mix. Describe and classify
the water by its observable properties. Using the digital scale,
determine the mass of the salt water. Is the salt water denser than
the water without salt?
STEP 4: Place the other uncooked egg into the water. Does the
egg sink or float?

EXPLANATION

Adding salt to the water makes the water denser than the egg,
allowing the egg to float. The egg sinks in the water without salt,
since the egg is denser than the water.

SCIENCE SAFETY

PLEASE follow these safety precautions when doing any science
experiment.

• ALWAYS have an adult present.
• ALWAYS wear the correct safety gear while doing any
experiment.
• NEVER eat or drink anything when performing any
experiment.
• REMEMBER experiments may require marbles, small balls,
balloons, and other small parts. Those objects could
become a CHOKING HAZARD. Adults are to perform those
experiments using these objects. Any child can choke or
suffocate on uninflated or broken balloons. Keep uninflated
or broken balloons away from children.
