A 3D model of the water cycle can be easily made using ordinary household items and the sun's warming power. To make the model, create a closed system where evaporation and condensation may be observed.Know More
The requirements are simple. Begin with a bowl and a piece of plastic wrap. The first jar or bowl is filled to about a quarter's height with water. A rock or coffee mug is then placed inside. The plastic wrap is then placed on top, and the bowl is taped shut.
Placed in the sun, the water will first evaporate and then condense, eventually becoming liquid droplets that will "rain" down. A few drops of food coloring added to the water can enhance the visual effect.Learn more about Graphic Design
Though there are a few different ways to create a tornado model for a science project, the easiest way is to use water, plastic bottles and a few other common household items. Complete the project in less than an hour.Full Answer >
Dettol is commonly used to clean cuts and wounds and can be used to disinfect household surfaces as well as freshen up linen by adding some to a rinse cycle. When cleaning skin surfaces such as cuts, Dettol should be diluted as it can be toxic, even by inhalation.Full Answer >
The systematic training cycle is a formal training model that consists of four phases: analysis, design, implementation and evaluation. The first phase is the identification and analysis of training gaps within an organization, which is followed by the designing of a training program. The training program is implemented in the third phase and evaluated in the final phase.Full Answer >
The major advantage of the incremental model is that it generates a working application faster and earlier during the software development life cycle; however, problems can occur with iteration phases if not implemented correctly, and developmental costs can be high. For it to be successful, the entire system must be clearly defined before it is broken down and developed in incremental models.Full Answer >
