The Floating Egg Lab

Ingredients	Observation of egg in water before adding ingredients	# of teaspoons added	Observations when ingredient added	Observation when water carefully added
Salt	It’s At The Bottom Of The Cup	6 Teaspoons	It doesn’t go up much, but it goes up.	It floats but in the middle of the water, not all the way at the top.
Epsom Salt	It’s At The Bottom Of The Cup	3 Teaspoons	It starts moving upward.	It stays in the same place, it doesn’t move upward.
Sugar	It’s At The Bottom Of The Cup	10 Teaspoons	It starts moving upward.	It floats on the opposite side of the side where we added water.
Baking Soda	It’s At The Bottom Of The Cup	4 Teaspoons	It moves upward slowly.	It sinks as we add the ingredient.

1)      What Did You Notice While Using Each Ingredient?

I noticed they all floated up slowly, but in the end they always end up floating. Also that we never used less than 3 Teaspoons.

2)      Why Do You Think This Occurred?

I think this happened because the egg is heavy enough for it to sink, but the more ingredients you added the more substances the water contained. So that caused the egg to start floating rather than to sink.
