Preparation of science fair project

How to prepare a final report for your science fair project

Generally a teacher would give guidelines as to what is expected in the final report, but if none come home with the project directions, then I recommend including the following sections (similar to a scientific paper) in this order:

Title, author, date

Abstract: 1 paragraph summary of entire project

 Introduction: 
Background information including things like the motivation for picking your topic and why the project is important. Also include the hypothesis in this section.

 Methods and Materials:
 This section can have several sub-sections. It would start with a list of what was used in the project. Also included would be a description of all the variables – independent, dependent, controlled and the control and level of replication. Once all that is spelled out, start with the procedure and describe the steps needed to complete the project. Photos of the process would also be included here.


Results: 
This section highlights the data – i.e., tables and graphs with descriptions of what they show. Remember that descriptions go above tables, but below graphs. Photos of results would go here.

Discussion:
  Now is the time to discuss the results – what does the data show, what did you learn, what surprised you, why do you think the results happened the way thbey did. Here you can also add what you would do better and what you would do as a follow-up experiment.


Conclusion: 
Specifically state if the data support or refute the hypothesis.


Acknowledgements: 
Thank everyone who helped you including your teachers, friends, mentors, and parents.

Writing a final report is one of the best ways to prepare for the judging interview.

Build you own 500 watt power inverter UPS

500 Watt 12 VDC to 220 VAC Power Inverter (UPS) uninterruptible power supply

Build you own 500 watt power inverter UPS 

Introduction:

Power inverter is a device which converts 12 volts to 150 volts of D.C into 220 volt to 110 volt. Power inverter is commonly known as UPS. UPS stands for uninterruptible power supply which is the modified form of inverter. Due to the lack of electricity the importance of inverter increases day by day. The substitute of load shedding is generator or UPS.

Few advantages and disadvantages of generator are as follows.

Its first advantage is, it can run many electronic devices and it can supply electricity for the long duration of load shedding. The disadvantages are noise pollution, usage of fossil fuel cost it too high. The alternate of generator is UPS, it has also some advantages and disadvantages.

The supply of electricity goes uninterrupted, it do not require much effort. Its backup depends on battery, as many amperes of the battery it has, that much it backup it would provide.

Its disadvantages are, recharging takes a lot of time and in the long duration of load shedding battery cannot b recharged so that it stops working. By putting excessive load the duration of backup reduces. Its performance is about 60% to 90%. Read Full article 500 Watt 12 VDC to 220 VAC Power Inverter (UPS) uninterruptible power supply
