An eco-column is used to model an ecosystem on a smaller scale. The purpose of an eco-column is to examine how an actual ecosystem would respond to different conditions. Eco-columns typically have three chambers: the aquatic chamber‚ decomposition chamber‚ and terrestrial chamber. The aquatic chamber contains water and an aquatic plant‚ and it is at the bottom of the eco-column. The decomposition chamber contains items that will work as decomposers and as a possible catalyst for plant growth. Examples

his story on the Trajan’s Column‚ and to have the effect he wished to convey. The sculptor wanted to tell the story of the emperor Trajan to the people of Rome and illustrate his victories and achievement by the carvings on the column. He uses the technique “continuous narration” to let the story unfold within the spirals without any interruption. This progression of events is not always consecutive and is sometimes simultaneous. Due to the increasing distance of the column from the ground‚ the sculptor

Chromatography is the separation of compounds to allow us to see the different colours of that compound‚ for instance we may use chromatography in a school lab to see the real colour compounds of plants and grass‚ by using chemicals such as acetone we it will allow the object to break compounds and thus we can see the true colour of the grass. In today’s society there are many real world applications which use the chromatography technique in their line of work‚ an example of one of these applications

Candy chromatography My experiment is called candy chromatography. This project is mainly about the colors that are mixed with other colors to make candy markers Koolaid and much more. I think that only the color of the candy is going to show up on the coffee paper. I think that threw the entire experiment the color in the candy is going to show up the entire time. I think this is going to happen because most of the colors are solid colors. The material and equipment used was a sample of candy

Chromatography lab Purpose: To separate food colorings into their component dyes using paper chromatography. Materials: Chromatography paper‚ Food coloring‚ Ruler‚ Pencil‚ Solvent solution‚ Test tubes‚ Test tube rack. Safety precaution: wear aprons‚ to make sure that you don’t get any of the alcohol on your clothes‚ and if you break a test tube you don’t get glass on you. Procedure: See-attached handout. Results: See chromatography with Audrey’s lab report.

corresponding anthocyanidins using paper chromatography‚ and spectrophotometric analysis procedures. Based on experimental data the blueberries contained the most amount of anthocyanins at 1.92 x 10-6 g‚ followed by blackberries at 1.19 x 10-6 g‚ finally followed by raspberries at 5.84 x 10-7 g. The paper chromatography data also supports the idea that blueberries contained the most anthocyanidins‚ since it contained the most streaks on the chromatography paper. The main conclusion that can be
