In your science journal, record the following:
1) Setup*(see photos below):
a) labeled diagram of the setup
b) description of the setup and activity
2) Observations:
What happened when you squeezed the bottle? (Provided specific, detailed record of actions and changes during the activity? Also, describe any factors that affected the outcome of the activity -- the amount of pressure, type of bottle, volume of water, ...)
3) Inferences & Conclusions:
Q1: Why does the eyedropper float? (State the observations you made -- in some cases, the “experimenting” you did -- that support your inference/conclusion.)
Q2: What causes the eyedropper to sink when you squeeze the bottle? (State the observations you made that support your inference/conclusion.)
