* To convert from oC to oF, simply take the temperature in oC and multiply by 1.8 and add 32.

RIGHT-HANDED COTTON BALL GRAB

1.  Grab marbles

2.  Put them in a beaker on a scale (make sure scale is reading zero with only the beaker sitting on it)

3.  Record mass of marbles

4.  Calculate % error of hypothesis

LEFT-HANDED SPONGE SQUEEZE

1.  Dip sponge in 1000mL beaker

2.  Squeeze into 600 mL beaker

3.  Pour into graduated cylinder (measure volume)

4.  Pour back into 1000mL beaker

5.  Calculate % Error

THERMODYNAMIC FINGER DIVING

1.  Let everyone put their finger into water and guess the temperature.

2.  Use thermometer to get actual temperature

3.  Calculate % Error

STRAW JAVELIN

1.  In the front of the room, throw the straw from the tape.

2.  Measure distance to the middle of the straw

3.  Calculate % error

4.  Please leave straws on the table

COTTON-BALL SHOT-PUT

1.  Get meter sticks and cotton-balls and go in front of my desk

2.  Throw cotton-balls

3.  Measure distance each throw goes

4.  Calculate % error

5.  Please leave cotton balls

PAPER PLATE DISCUS

1.  Place feet on starting line

2.  Throw the discus (one throw only)

3.  Estimate the distance you threw the “discus.”

4.  Record that value.

5.  Measure distance from starting line to the position of the paper plate

DIMENSIONAL ANALYSIS PRACTICE

1.  At this station you will continue practice on your dimensional nalysis sheet. TRY THOSE TWO-STEP PROBLEMS!!

SYNCHRONIZED LUNG TESTING

1.  Get stopwatches for people in the group.

2.  Everyone in the group should start holding breath at the same time.

3.  Record time when you let go of your breath

4.  Calculate % error
