We are testing different watt light bulbs and how it affects how fast the chads rise. We are using 300, 200, 100 and 60 watt lights bulbs. We are timing how long it takes for the chads to rise with each different light. Photosynthesis is a chemical process through which plants, some bacteria and algae, produce glucose and oxygen from carbon dioxide and water, using only light as a source of energy. Photosynthesis converts massive amount of Sunlight into electrical and then chemical energy. The…

Preparation of the sample The sample must be prepared for testing by: • Dissolving the solution in distilled water • Filtering the dissolved solution • Evaporating the water to increase the concentration Equipment 1 beaker 50ml of distilled water Stirrer 1 Funnel Filter paper 1 crucible 1 Bunsen burner 1 heatproof mat 1 tripod 1 teaspoon of soil sample 1 conical flask 1 Pipeclay triangle Method 1. Place the soil sample in the beaker and add 50ml of distilled water and stir until…

Methods: To begin, our group acquired three premade vials of .1ml mammal blood with coagulant. We then labeled the vials numbers one, two, and three. In vial number one we added 1 ml of Stock 300 mM NaCl, and no distilled water. This resulted in a NaCl concentration of 1.8 percent. In the second vial we added .5 ml of Stock 300 mM of NaCl, and .5 ml of distilled water. This resulted in a NaCl concentration of .9 percent. In the third vial we did not add any Stock 300 mM of NaCl, and 1 ml…

Biomedical equipment technicians or medical equipment repairers troubleshoot, install, and maintain medical devices used in patient treatment and diagnosis. Projections show that the growth of biomedical equipment technician jobs will be excellent in the coming years. The majority of medical equipment repairers hold at least a 2-year associate's degree in biomedical technology, although a 4-year bachelor's degree may be needed for career advancement. Required Education Associate's or bachelor's…

Particle (steel and spherical particles) waterjet is a new type of waterjet that can effectively break rock and other materials. In this study, simulation combined with experimental method was conducted to optimize the jet parameters (i. e., velocity, water pressure, impact time, concentration, diameter, and standoff distance) for modeling the rock breaking performance of a particle waterjet. In particular, the changes in the rock and particle properties after the impact were analyzed based on…

The aim of this experiment is to determine through calculations the concentration of acetic acid content within a common white vinegar. Apparatus / Materials Plastic Tray Electronic scales Sodium hydroxide Volumetric flask and lid Glass funnel Distilled water Pipette Volumetric pipette/s (5mL, 20mL) Bulb Conical flask Retort Stand Burette Burette clamp White Tile Method Place the plastic tray on the electronic scales and press tare to set the wither to zero; Weigh out 0.7993g of Sodium…

Methods Column chromatography was set up using a 60 ml syringe clamped to a ring stand. The syringe was plugged using a small amount of cotton. An Erlenmeyer flask was placed underneath the column to collect any excess material. Eleven 20 ml vials were labeled numbers 1 through 11. Silica gel was measured to 42 ml using a graduated cylinder and then moved into a 150 ml beaker. A slurry was created by adding 50 ml of hexane to the beaker containing the silica gel. The slurry was stirred for…

To begin, we put 200mL of water with one drop of green food coloring into a pie tin. We then mounted the short candle into the clay in the center of the pie tin. After, we lit the candle, waited approximately five seconds and bottled the candle. Lastly, we waited for the flame to go out and measured how high the water rose in the bottle. This process was repeated for the medium and tall candle as well. Data Table: Height of Candle Height Water Rose in Bottle Short 4cm Medium 4cm Tall 4cm…

Umama abid Lab Partners: Olivia, Emily Ms. Olenick SBI4U 9/23/2017 Analysis The solution in the dialysis tube turned bluish black in color due to the transfer of iodine from the beaker to the bag which contains starch and glucose . The solution in the beaker turned brown after Benedict’s test ( table 1) . This indicates that the dialysis tubing was permeable to both glucose and iodine but not starch ( work helper, 2017) . Starch didn't pass because the solution in the beaker which…

During the extraction process, the sand bath was set to 20℃. The 1.00 gram of ground nutmeg was transferred to the round-bottom flask (RBF) using the plastic funnel. Three milliliter of tert-butyl methyl ether and two or three boiling chips were added into the flask. The black plastic connector was used just like the distillation column with air condenser set-up. The flask was clamped to the ring stand using 3-pronged clamp. The flask was lowered into a slightly depression in the sand without…
