Why Do Egg Float In Salt Water
Question:
Will the egg float or sink if put in salt water?
Purpose:
I want to know why the egg floats in fresh water and not salt water. I want to know if the egg will float in salt water, Also this shows why materials float easier in saltwater and sink in freshwater.
Research:
Since the egg’s density is higher than the density of freshwater the egg will sink. Density is mass per unit volume, which means a measure of how much mater is in a certain volume. If you add enough salt the egg will float again. The salt makes the water denser because the salt creates more mass and some what keeps the volume at the same level. When enough salt is add that means that the water has a higher density level than the egg. The ability of making something …show more content…
Since saltwater is denser than freshwater the egg has a greater chance of floating.
I think that in freshwater it will not float
In mixed water it will float because there is some salt left.
Martials:
• A clear plastic or drinking glass (Size 2000 ML)
• Water (1000 ML)
• fresh egg
• salt (Size one small tasting cup of salt)
• teaspoon
Method:
1. First place an egg in a cup half filled with water. (Observe what happens.)
2. Add/stir salt in water (observe what happens stop when egg floats)
3. carefully add more water into the cup until it is almost full (pour the water to the side so it doesn’t mix with salt. Observe what happens.) Experiment:
We did the experiment on Friday December 4, 2015 in science class
The people in my grope were Tahmid (me coordinator, experimenter and peace keeper.), Ridita (opinion seeker, recorder) and Asad (verifier, clarifier and material handler).
Observation:
Salt water: we put 3 teaspoons of salt and put the egg in the cup. The saltwater did not have an effect on the egg. Then we put 5 teaspoons and it still did not work. So lastly we put 7 teaspoon and the egg bounced in the middle and floated back up to the top.
Fresh water: the egg went directly
