Materials

Procedure

  1. Carefully place the egg into the drinking glass and fill with water until the egg is fully covered and the glass is about 3/4 full. Observe what happens to the egg: is it standing up? lying sideways?

  2. Use the teaspoon to measure a small amount of salt. Add to the water in the glass and gently stir.

  3. Repeat step 2 until the egg begins to float above the bottom of the glass. How can this be?

Analysis and Conclusion

Hmm... it seems nobody's added a conclusion for this experiment yet. You can suggest one here.
