Materials have cylinder 2 marbles Liquids to test such as water, corn syrup, back toothola oil, motor oil masking put down 1 cm ruler stopwatch that is accurate to 0.1 or 0.01 ssSAFETY NOTE disclose Texas Science Safety Manual for lab and investigation guidelines http//www.tenet.edu/teks/science/safety/safety_manual.htmlEngagement Place a wooden ramp on a business deal of books. Challenge students to predict which of three crystal clears (syrup, water, and motor oil) provide reach the commode of the ramp first. Use whizz drop of each liquid. Have students write their predictions and observations in their science journals. Ask student to identify which place of matter is best represented by this demonstration. research1. Fill a graduated cylinder with genius of the liquids (water, corn syrup, canola oil or motor oil), up to near 5 cm from the top. 2. Mark with read a convenient starting evince about 2 cm below the surface of the liquid (which will allow the sphere to reach goal velocity before you begin making measuring sticks). You can use either the top or the bottom of the tape, but use the same points for each measurement you make when you drop the spheres. 3. Mark an ending point about 5 cm from the bottom. 4. Measure the remoteness between the starting and ending points, and enter the firmness of purpose in the data defer as reflect distance. 5. Drop the sphere into the liquid and start measuring time when the sphere reaches the first masking tape line. Stop measuring time when the sphere passes the second piece of tape. Repeat the time measurements for a full(a) of 5 trials. 6. Clean the graduated cylinder and fictionalise procedure with other liquids. 7. Complete the data table by averaging the times for each substance. Use this time when calculating the speed of the sphere.
