e.  Time how long it takes you to move the drop through the maze. Record your results.

2.  H2O STRETCH

a.  Predict how far you will be able to stretch a water drop.

b.  Place a water drop that fills the beginning circle on the scale.

c.  Use two toothpicks to stretch the water on the scale.

d.  Measure the distance you can stretch it without the water drop separating. Record your results.

3.  FOLD ‘N FLOAT

a.  Fill bowl with water. Float the foil in the water.

b.  Predict how many times you can fold the piece of foil in half and still have it float.

c.  Fold it in half- see if it floats.

d.  Repeat step C until the foil sinks. Record how many times you were able to fold the foil and still have it float.

4.  BALANCE BEAM (head or tails)
