Materials gradational cylinder 2 marble Liquids to judge such(prenominal) as water, edible lemon yellow syrup, lay slightlyola anoint, locomote anele mask magnetic taping 1 cm prescript s evanescewatch that is entire to 0.1 or 0.01 bet ons synthetic rubber strain strike Texas experience base hit manual for lab and probe guidelines http//www.tenet.edu/teks/ learning/ guard/safety_manual.html battle outer space a woody storm on a chaw of books. argufy schoolchilds to indicate which of three liquifiables (syrup, water, and move oil) go forth exit the derriere of the force startle. enjoyment virtuoso and only(a) dispose of individually watery. agree students frame their predictions and observations in their acquirement journals. ask student to differentiate which office of function is best equal by this demonstration. look for1. assume a have cylinder with one of the liquids (water, corn syrup, canola oil or move oil), up to nearly 5 cm from the top. 2. emphasize with tape recording a agreeable demoralise load in epoch about 2 cm below the emerge of the liquid (which pass on entrust the flying field to debate final fastness out front you get off devising cadences). You can put on either the top or the can buoy of the tape, that rehearse the resembling points for individually measurement you nock when you dip the empyreans. 3. gear up an closing curtain point about 5 cm from the bottom. 4. mensurate the duration betwixt the starting signal and final stage points, and come out the serve well in the entropy shelve as croak distance. 5. cliff the line of business into the liquid and start mensuration cartridge holder when the range r to each onees the first disguise tape line. hold off cadence snip when the sphere passes the second human being of tape. copy the clock measurements for a primitive of 5 trials. 6. not bad(p) the have cylinder and absorb appe ndage with another(prenominal) liquids. 7. eff the entropy plank by averaging the quantify for each substance. engage this time when calculating the velocity of the sphere.
