Science Lab "The Amazing Egg"

The Amazing 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








Egg sank to the bottom.



5 tps.

Egg slowly started to float.

It sank again.
Epsom Salt

Egg sank to the bottom.





 
8 tps.

Egg slowly started to float.

It kept on floating.
Sugar

Egg sank to the bottom.






4.5 tps.
 
Egg slowly started to float.

It sank again.
Baking Soda

Egg sank to the bottom.






6 tps.

Egg slowly started to float.

It was not floating and it didn't sink either. It was in the middle.



Conclusion
·         What did you notice while using each ingredient?
·         Why do you think this occurred (use scientific language)?
·         Did everything go well during the lab? If no, what would you change next time?
      Each ingredient made the water a little more denser. Then it came to a point that the water was denser than the egg. So the egg started to float.

  1. Your conclusion was not detailed enough. Be sure to write in paragraph form and assume the reade knows nothing about desnsity.
