How To Build A Greenhouse Grade 7 Science Fair Projects

V

A greenhouse is basically a structure that has been designed to capture and retain the heat from the sun. It is used to grow plants when the climate does not want to cooperate. Greenhouses can be used in a number of science fair projects and can be used to test concepts from a variety of fields of sciences including engineering, physics, botany and biology.

Project #1 Capturing Heat Energy

In this project the students will be designing a greenhouse that captures heat energy from multiple sources. They will be capturing heat energy from the sun and geothermal heat energy from the ground. This project will require the student to learn about heat extraction techniques related to solar energy and geothermal energy.

Sample hypotheses that can be tested with this project include:
(1) The thickness of the plastic used for enclosing the greenhouse impacts the amount of heat conservation in the greenhouse;
(2) The opaqueness of the material used for enclosing the greenhouse impacts the amount of heat conservation in the greenhouse;
(3) The depth of the insulation on the floor of the greenhouse impacts the amount of geothermal heat conservation in the greenhouse.

Project #2 Growing Radishes

In this project the student will build a greenhouse so that they can grow radishes and conduct experiments on the radish plants during times of the year that are not normally conducive to gardening. Radish projects can look at a number of things. For example, students can try to cross pollinate radishes with another root vegetable like carrots, they can attempt to grow radishes in sand or they can try to manipulate the size of the radish by exposing the plant to 20 hours of light per day.

Project #3 Engineering Greenhouses

For students that are interested in engineering, greenhouse science fair projects can be developed with an engineering focus. For example, students can try to develop a greenhouse using nothing but materials that are normally thrown out or recycled, such as cans, bottles and plastic containers. Students will not only need to design and build their greenhouse, but they will also need to test the effectiveness their greenhouse has in regards to collecting and conserving heat energy.

Project #4 Studying Solar Energy Applications

The final project option will be an application project. Students will be learning about solar energy and how to use this knowledge to harness the suns energy to heat a greenhouse. For this project students will design and build a greenhouse that maximizes the energy delivered by the sun. A good approach for this project is to see if their design can magnify solar energy within the greenhouse to make it effective in cold weather.

Dynamic Signage Totem Hardware

T17

The publicity is massive for dynamic advertising, now manufactures are coming up with progressive dynamic marketing solutions with their eye on the entry level digital poster solutions.

This is a twist on a lcd advertising screen, as this unit features 4 displays all 17″ and in the landscape orientation on a unique bracket, these just like the digital poster are fed with media from storage cards.

The foremost distinction is that this solution can have 2 different ads consecutively at the same time increasing your ad earnings if you are a dynamic signage advertising firm. These are to be utilized indoors and the foot has the provision to be bolted to the ground to prevent unauthorised removal.

One challenge of digital posters is how to refresh media as each lcd advertising screen is standalone, now media can be distributed over the net to a hard disc drive and then fed to each screen, creating a secluded access solution.
With companies looking to build up their market segment and looking into revolutionary ideas to attract more clients to their store lcd advertising displays are increasing in reputation, but with this hardware it opens up a new level of promotion, as it could be set up initially to be updated manually then if the shop owner decides to run it throughout their chain they can then pay for the HDD unit to run them from one chief setting, slashing commuting time and outlay in delivering fresh content.
The totem can also be tailored to be installed on buses and even on ferries, so commuters can be entertained whilst they are in transit, dropping their perceived wait time, also identified as time warping.

Or if providers want to have a modern look they can use a cable, the 4 merchandising tvs are on the brink from the cables.

This gives you a rather stream lined and proficient solution and perfect for in windowpane dynamic promotion.

Ideas For Science Fair Electricity Projects

Science Fair Electricity

In the 21st century those citizens of developed nations often take for granted their access to electricity. We all simply flip a switch and have all manner of electrical gadgets at our disposal. In the last couple of decades these opportunities have grown to include communications across the globe via the Internet. All of this is possible due to our access to electricity and other forms of power. While this has been around over 100 years now, science fair electricity projects are still some of the favorites for students. Many of us who use electricity every day have no idea how or why this works. We are clueless about the science of protons, electrons, and neutrons while reaping their benefits on a daily basis. Students who choose science fair electricity projects are not among the uneducated! They are some of the brightest students who are able to understand the invisible processes required to make the light bulb come on when the switch is flipped up and go off when it is flipped down.

Science fair electricity demonstrations are some of the most interesting at the event. While some projects involve computer graphics or visual representations of the processes that the student has studied, science fair electricity allows for hands on experience. Students who make presentations for science fair electricity events can give live demonstrations of the nature of their subject. There will be groups of students and parents gathered around for a chance to participate in these experiments. All spectators will want to place their hand on the static electricity ball just so their hair will go flying in all directions. Other braver spectators will volunteer to touch their tongue to a potato that they are sure will not shock them. This is always a great crowd pleaser when students get their parents and teachers to volunteer for mild but unpleasant shock!

While all science fair projects hold interest, the science fair electricity projects are definitely the liveliest! Students can use sensation, light and sound to demonstrate their science fair electricity project findings. Students, teachers and parents alike will leave the event with a greater understanding of the properties of electricity by learning the concepts in hands on, or tongue on, fashion!

General Concepts about Object-Oriented Programming

SS

The programming style that we usually call object-oriented programming (OOP) has appeared relatively recently in the history of programming languages. This is a particular and very convenient style for many situations. It was designed to overcome the limits of structured programming based mainly on the widespread use of procedures, functions, pointers or other more or less developed data types.

Although structured programming is very practical for small software systems or reduced non-graphic applications, it should be avoided when dealing with large applications that use graphic elements where object-oriented programming is recommended. Object orientation means organizing software resources as a collection of distinct and discrete objects, which includes both data structures and their processing functions. This organization is an extension of structured programming in which the data structures and processing functions are only loosely connected. All items have their own identity and are perfectly distinct.

An object is defined as an abstract concept, a specific and useful element for any application. Objects serve two specific purposes:

– they provide a better understanding of the problem to be solved;

– they provide a base design for implementation.

A class of objects encapsulates a certain number of objects with similar properties. This similarity refers to both the description (data and attributes) and the behavior (functions or methods). Attributes are unique features within an object class. Each attribute receives a certain value which can be modified during the objects life cycle. Two or more objects can have the same or different values for the same attribute.

Methods or operations are processing functions applied to objects of a certain class. All objects within a class admit the same set of methods, methods which in return may receive any number of additional parameters. In order to apply various methods to an object, it has to be created (defined). Defining an object is called instantiation. Once an object has fulfilled its mission it is removed.

Abstraction is a fundamental human trait that allows us to build models and thus cope with complexity. In every field of human activity, project approach is based on building a model for a better understanding of the problem to solve. Software engineering makes no exception. Through abstraction the essential key aspects are isolated from the non-essential ones. Therefore, each problem might have several adequate models.

In the software engineering industry, structured programming has made a big step forward defining three perspectives needed in order to properly address any application. These perspectives, also known as models, are: the static model, the dynamic model and the functional model.

There are currently several object-oriented methodologies used for analysis, design and implementation of software resources. One of these modeling methodology is the OMT (Object Modeling Technique) methodology. This method of modeling involves the planning of the various development stages and a graphical representation of objects and their relationships.

Amadeus Consulting Discusses Do It Yourself App Programming

Another issue is software support. Since your tools are limited, supporting and troubleshooting your application can be very difficult, and it can be a very manual and time consuming task to find and fix bugs. This makes it a very unwise choice for commercial applications (such as creating an app to sell, or a website to promote your business and engage your customers), but can still be suitable for more personal use.

In terms of helping you learn programming, requiring you to find and fix bugs can be very helpful, as you must learn and understand what is going on. But for people looking to quickly create something useful, this can be time consuming and frustrating.

Also listed under “the bad” is the over-estimation of what you can build with little or no programming experience. These tools allow you to build the core framework of very basic applications, with strict limitations on the features you can include (although some allow elements to be added at the code level, but that requires an amount of expertise). What many users find missing is the ability to manage the final look and feel of an application, which can be almost as important as the functionality of an application.

Overall

Do-it-yourself programming tools can be a great way to learn and experiment, but require a lot of learning and have many limitations which restrict your ability to create professional-quality applications.

As a custom software development company based in Boulder, Colorado, we are often asked if these types of tools are a threat to our core business. The answer: definitely not. These tools help people better understand the time and expertise required to make quality applications, and they help build interest in the technology itself.

Many people and small companies are interested in do-it-yourself options because they hope it will save money over hiring someone else to do it. However, there are many other options that may be better suited to commercial needs, that wont break the bank. Some of these include semi-custom websites, and simple mobile apps which are designed from a prebuilt template, but then customized to fit a specific need.

These other options can also benefit from customization by experienced programmers, which can help ensure that it meets all of your needs and can be easily expanded as your company grows. One example of this is the Virtuoso Website Builder and Support which offers not only customized websites, but also 24/7 support, cloud hosting, SEO, and many other benefits. The sites are based off common templates but still benefit from an entirely customized look and feel. This saves time and money without reducing quality.

As a custom software company, we appreciate anything that helps people understand technology and become a part of the creation process. As people continue to imagine and experiment, we will continue to specialize in helping people translate those dreams into reality.

Google Io Showcases Wearable Technologies

KUK

It seems that wearable technology is going to be the in thing in the next few years. During the 2012 Google I/O, a major theme that was being pushed would be technology that would be wearable by the consumers.

Instead of having to bring along a separate device in bags or pant pockets, it seems that Google (and other tech companies for that matter) would want users to actually wear them as part of their outfit. Perhaps the idea behind this is that it would make the device much more embedded into the lives of its users.

Historical Use:

Industry observers mentioned that the idea is not that far-fetched. In fact, the military would already have prototypes and actual products of utilizing wearable computers. Usually, these military themed devices are used either for their communications capabilities or their GPS functionalities. However, the trend is to slowly bring these military devices into use for regular consumers.

In fact, there are now more companies who have tried to integrate their devices into more wearable designs. For example, MIT researches have long been looking at how they can manufacture wearable computers. Another example would be on how Apples iPod Nano has now made a wristband like peripheral which you could use to wear the highly capable device as a wrist watch.

Googles take:

Not one to be left behind by technology, Google also has something up their sleeve. They have previously announced the Google Glass. Google glass is a wearable device that would provide its users with a video game like heads up display while they are doing their everyday tasks.

Some analysts believe that Googles involvement in wearable technology would help push forward the acceptance of wearable devices. As of now, the use and acceptance of it is usually limited to the aforementioned military uses as well as to some of the rich and tech savvy people.

Analysts are speculating that similar to what happened with Android and smartphones, a Google role in the push for wearable technologies would also help push the number of devices that would provide this kind of function to the consumers,

Of course, people should note that despite the Google glass being highlighted in this years Google I/O, the actual thing is still in development. Many experts believe that the soonest that it would become available for commercial release would still be in 2 or 3 more years.
