Activity A:

1. What happened as each egg was dropped into the solutions? Why?

    

2. Does this effect happen to other objects as well as eggs? Test other possible objects and record the results.

    

3. The ocean is composed of salt water, so do objects have a better tendency to sink or to float in the ocean?

    

4. Determining the density of the wood block and the marble using scales and volume.

   Density = Mass / Volume

--What is the volume of the wood block? The mass? The density?

--What is the volume of the marble? The mass? The density?

--Which object(s) would float? Why?

Activity B:

1. What happens to the pipette when it is dropped into the two-liter bottle of water? Why?

   
   
   

2. What happens to the pipette after squeezing the bottle? Why?

   
   
   

3. Explain what happened to the two-liter bottle and why any object of similar structure would react the same.
   
   
   
   
   
   
   
4. Where else can you find similar water pressure effects on objects, which will cause even humans to witness the effects of buoyancy.

Activity C:

1. What happens to the clay when it is flat and placed in the water? Why?
   
   
   
   
   
   
2. As you begin to form the clay upward, what effects, if any, do you see occurring in relation to the object being able to float? Describe what you see.

    

    

3. As you begin to see that the clay is floating, begin placing marbles in each to see how many it takes before it sinks. Keep track of each trial and the number of marbles used.

    

    

4. Describe what you have observed throughout the experiment and why some of the shapes of the clay would float and others would not float. Why do you think this is occurring? Are there any other objects of similar shape that could also be tested that would prove your interpretation of the object is a correct one?
