Agricultural Science Essay

Materials Graduated cylinder 2 marble Liquids to test such as water, maize syrup, finishola crude, tug oil Masking magnetic attach 1 cm ruler stop watch that is accurate to 0.1 or 0.01 secondsSAFETY business line See Texas Science Safety manual(a) for lab and investigation guidelines http//www.tenet.edu/teks/ erudition/ gumshoe/safety_manual.htmlEngagement Place a woody wild leek on a throng of books. Challenge students to predict which of three liquids (syrup, water, and motor oil) will r all(prenominal) the bottom of the ramp first. drop one drop away of each liquid. Have students write their predictions and observations in their science journals. Ask student to identify which blank space of matter is best represented by this demonstration.Explore1. Fill a gradational cylinder with one of the liquids (water, corn syrup, canola oil or motor oil), up to somewhat 5 cm from the top. 2. Mark with tape measure a convenient starting billet close 2 cm down the stairs th e surface of the liquid (which will let in the demesne to reach terminal pep pill before you begin making measurements). You can use either the top or the bottom of the tape, but use the said(prenominal) points for each measurement you make when you drop the line of businesss. 3. Mark an ending point about 5 cm from the bottom. 4. Measure the exceed between the starting and ending points, and present the answer in the data slacken as Fall distance. 5. Drop the sphere into the liquid and start measuring cartridge holder when the sphere reaches the first masking tape line. Stop measuring clock when the sphere passes the second piece of tape. Repeat the time measurements for a total of 5 trials. 6. great the graduated cylinder and repeat unconscious process with other liquids. 7. Complete the data slacken by averaging the times for each substance. Use this time when calculating the speed of the sphere.
