Hooked On Science: Salty Egg Experiment
Salty Egg
INGREDIENTS
- 2 Clear Plastic Cups
- Water
- Salt
- 2 Uncooked Eggs
I INSTRUCTIONS
STEP 1: Fill the one of the clear plastic cups half of the way with water. Describe the water using its observable properties.
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 the water using its observable properties.
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, which allows the egg to float. The egg sinks in the water without salt, since the egg is denser than the water. Go to www.hookedonscience.org for more experiments that might get you and your family “Hooked on Science.”
