Now fill the cylinder with the aggregate to 1/3 the height of the cylinder using the scoop. 3. Compact the aggregate with the tamping rod giving 25 strokes without touching the bottom of the cylinder then stomp the cylinder on the ground 3 times. 4. Repeat steps 2 and 3 another two times so that the cylinder is full and has now being compacted 3 times. 5. Remove the surface aggregate

Parachute Experiment Aim: To investigate the effect of surface area on a performance (more the amount of a parachute better the performance) of a parachute. Hypothesis- More the amount of holes in a parachute‚ faster the rate of the fall. Variables: Dependent variable- The time it takes for the parachute to reach the ground. Control variables:Mass > Adding or subtracting mass from the load. > Clay can be molded around the load to increase mass. > Parts of the load can be cut off to decrease the

villalon@rocketmail.com Abstract In analyzing the chromatography of analgesics‚ thin layer chromatography (TLC) was used. A very thin (micron) film of silica is coated on a glass plate or a sheet of aluminum or plastic. The ingredients of commercial analgesics were characterized in comparison with chromatograms of aspirin‚ Acetaminophen‚ caffeine and mefenamic acid. After the TLC was placed inside a UV chromatography box‚ it appears that the sample analgesic contains D‚ which is mefenamic acid.
