This experiment is to show how much carbon dioxide is produced during the reaction between an acid (hydrochloric acid) and marble. Equipment: Hydrochloric Acid (20ml) - 0.5M‚ 1M‚ 2M Marble Chips (2g per test) Large Measuring Cylinder Plastic Bowl (3/4 full of water) Rubber Tubing Glass Conical Flask Stopwatch Method The first thing that we did was fill the plastic bowl with water. We only filled it up 3/4 of the way because otherwise the water displaced into

Cover the graduated cylinder by putting your finger on top and place the cylinder in the 1000 mL beaker. Make sure the graduated cylinder is under the surface of the water. 4. Measure the difference between the height of the water in the graduated cylinder and the height of the water in the beaker. 5. Record the barometric

Used a cork borer to obtain 4 cylinder of potato tissue and pushed the potato tube out of the borer using a pencil. 6. Cut all these potato cylinders to same length using a scalpel-cut carefully away from my body. 7. I recorded the initial length of the potato cylinders on my result table. 8. Then I also measured the mass of each potato cylinder by placing in onto measuring scale and recorded the mass in the result table. 9. Afterwards the potato cylinder were placed into each test tube

| Starting air system for diesel engine - how it works Function of starting air system Diesel engines are started by supplying compressed air into the cylinders in the appropriate sequence for the required direction. A supply of compressed air is stored in air reservoirs or ’bottles’ ready for immediate use. Up to 12 starts are possible with the stored quantity of compressed air. The starting air system usually has interlocks to prevent starting if everything is not in order. A starting air system

WHY PLE ARE CALLED “AN EDUCATION IN MOVEMENT”? EXPLAIN HOW THE MOVEMENTS ALSO ENHANCE EMOTIONAL & INTELLECTUAL BEING? HOW CAN THESE MOVEMENTS LEAD TO INTEGRATION OF PERSONALITY? Dr. Maria Montessori is the founder of the Montessori method of education. She started her first classroom “Casa dei Bambini” or Children’s House in 1907. Montessori method of education stresses the importance of respecting children - “Help me to help myself”. Montessori education celebrates its 100th year in 2007. The

Lab The purpose of this lab was to find the mass‚ the length‚ the width and the height of 4 different cubes so we could calculate the volume and density of them. We also had to find the density of irregular shapes by dropping them into a graduated cylinder than subtracting the starting water volume by the ending water volume. Density is how much mass is in a certain volume of matter. Volume is the amount of room that an object takes up. Mass is how much matter is in an object. My hypothesis is that
