How To Build A Greenhouse Grade 7 Science Fair Projects

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.

Basic Materials Used In Making A Picoturbine Windmill For Your Science Fair Project

Magnet, copper wire, aluminum wire, screws and clips, cardboard, and wood are the basic materials to used in making your own PicoTurbine windmill science fair project.

A PicoTurbine is a small windmill structure functioning to produce a small scale electric energy. A windmill structure is a very suitable science project idea for renewable energy topics. It is an ideal science fair project because it can be built easily. The materials used to make such project can also be easily found in any hardware store. PicoTurbine windmill is basically made from the list of items below.

Magnet

The magnet is basically used to attach with the rotor disk place above the wooden base of the PicoTurbine. It’s securely attached with a double sided tape to a thick cardboard to function as a rotor mechanism. When the rotor spins the magnet’s magnetic field will release enough voltage to light the light emitting diode or LED.

Copper wire

A copper wire is used as a pathway of the PicoTurbine’s electric circuit. It is generally used in building the stator segment of the turbine. It is also use to transport the voltage in lighting up the light emitting diode or LED. Expose the copper wire on the end of the coils with sandpaper. Remember to get rid of any enamel left on the copper to have an efficient stator.

Aluminum wire

An aluminum wire is used to assemble the base and yoke of the windmill. Wrap the aluminum around the dowel. Bend and loop the aluminum wire with pliers to form the yoke as well. The yolk and dowel can then be placed on the center of a wooden base by screwing it with Philips head screw.

Screws and clips

Screws and clips are essential bearing parts that are used in assembling the different segments of a PicoTurbine windmill. A Philips head screw is specifically used to attach the yoke and the axle of the windmill. Retaining clips are metal clips that fastened the dowel to the rotor. Screws and clips are the joints and tendons of the whole PicoTurbine skeletal structure.

Cardboard

The cardboard is the base support of the paper blade and turbine patterns. A cut-out paper template is glued to the cardboard to give it more weight. A cardboard is also used to support the magnet and the rotor.

Wood

Wood is basically used as a foundation of the PicoTurbine. Since wood is a solid material and can easily be screwed, it is an essential base to hold all of the windmill’s parts. An 8? by 5? wood is the ideal size for an 8? PicoTurbine windmill. A half inch thickness of the wooden base is also a complementing support.

Prepare all the necessary materials completely before you will start building your PicoTurbine windmill. PicoTurbine windmill kits are also available in the market to ensure that you have all the materials that you need. Scissors, screw driver, and ruler are the tools that may come in handy.

What are the business benefits of NFC mobile phone technology

Near Field Communications, or NFC, is a new technology with unlimited applications.

NFC uses RFID technology built in to the latest generation of mobile phones to scan or swipe small RFID tags, which can be placed just about anywhere. Tags can be programmed to trigger different actions when they are swiped by phones.

Many businesses or organisations have field based operations that need managing in real time. NFC technology gives these businesses leading edge management capability.

NFC can be used in a diverse array of industries with mobile staff, mobile assets, or multiple sites and locations. Because NFC technology uses readily available NFC enabled mobile phones and inexpensive tags, it can be applied anywhere, and by any type of field personnel.

The key benefits of NFC technology for businesses with a field based operation include:

1. NFC is Easy to Use

Using NFC technology is so simple, it’s accessible to just about anyone.

All that’s needed to run NFC operations in the field are RFID tags which can be situated in key locations, and NFC-enabled mobile phones.

For field operations staff, using Over-C NFC technology is simplicity itself. Just tough a tag with a phone, and that’s it. An automated NFC management system then does the rest, recording the time and location of staff, and sending them any special information or data they may need on their NFC enabled mobile phone.

2. NFC Improves Communication

NFC is an extremely effective way of improving two way communications between managers and their staff in the field.

Whenever a field operative touches an NFC tag with their mobile phone the operational management team receive an instant and verifiable confirmation of the location of field staff. Field staff can benefit from automated reporting, which saves time and improves accuracy.

3. NFC Enables Real Time Management

NFC technology lets businesses operate and respond in real time.

When an NFC tag is touched by a mobile phone, notification is in seconds, so operations managers always know exactly where their field personnel are, and what they are doing.

NFC allows businesses to streamline the way people work at, and report from, remote locations. It also allows field based personnel to focus on what they do best, whilst managers benefit from greater visibility in field operations.

4. NFC Improves Customer Service

NFC technology actively helps businesses to deliver enhanced customer service.

Data reporting by field operations staff becomes faster, more efficient and more accurate.

Field operations managers can use this real time data to generate customer reports and measure results faster than ever before – and faster than their competitors.

In fact, using NFC technology in a business can give it a commercial edge to help it gain and retain high value clients.

How to Help Your 2nd Grader Love Science

Imagine back in time a bit to your old school days. Did your science teacher just stand there and present you with a bunch of facts and figures? Was looking at the pictures in the textbook the most fun you had in your science class?

If you were bored in science, imagine how your child feels in 2nd grade science class. This is not because there is anything wrong with science or that science is boring. The problem is, that it is being introduced the wrong way.

Make Science Exciting

A textbook works great as a guide to learning science, but should try and do more to make science really exciting. Science experiments are by far the best way to get a child interested in science.

One fun and simple experiment you can try is to put a small seed in a cup, add some soil and watch the process of life as it grows and sprouts. Out of all the 2nd grade science curriculum on the market, my absolute favorite is Apologia Science. I have found Apologia to be the best at really making science fun and engaging for children.

Children love to be engaged, especially 2nd graders. Let a chick hatch from an egg and let your child care for and observe it. This will not only help your child learn about science, but also about life itself.

Children Need to Be Allowed to Think for Themselves

When a child asks you how something works, your natural instinct is to explain it to just explain it all to them. Instead of just telling them the answer. Why not help them discover the answer themselves? This way you can teach your child how to think for themselves and learn the answer at the same time.

For example, if your child is curious about what certain fish eat, you can ask a question like, ‘Well, what kind of snack do you think this fish likes the best?’ Tell them a bit about what is available under the water and let them discuss it with you.

Do Different Liquids Produce Different Levels Of Urine Science Fair Projects

Students have many options when it comes to the development of their science fair projects. If students are interested in medicine or biology then this project is a great option. It will examine how different types of liquids are processed by the body.

Hypothesis

The hypothesis for this science fair project is that sugary liquids produce less urine then salty liquids do. The dependent variable in this hypothesis is the amount of urine produced and the independent variable in this hypothesis is the type of liquid that is drunk.

Supplies Needed

This science fair project will need several key pieces of equipment. First of all the student will need at least six to twelve test subjects that are generally healthy. The student will then need a urine collection and measuring device for each of their test subjects. These can be picked up at a medical supply company. The students will also need collection sheets which will be handed out to each test subject. Latex gloves can also be used when collecting urine volume samples.

The Experiment

To start with the student will need to conduct a control experiment. This will create a baseline of data to compare test results to. The control experiment will basically see how much urine is normally produced by each test subject on a daily basis. To collect this data each test subject will be given a urine volume collection container that fits into their toilet. They will then write down the volume of urine that they eliminate from their bodies on a daily basis over a week.

The test experiment will begin by dividing test subjects into two groups. Group A will be given sugary drinks and Group B will be given salty drinks. Each group will be assigned the same volume of liquid. The test subjects will be instructed not to drink anything other than their experiment liquids during the day. They will then monitor their urine output during test day 1, 2 and 3. The groups will then be given the other liquid type and the will be tested for another three days.

Data Analysis

The analysis of the data will involve several steps. First of all the students will need to organize the data by finding the average urine output for each test subject in the control experiment. This will create the baseline data. Next the average urine volume output for each test subject will be calculated for the sugary drink test. Finally the average urine volume output for each test subject will be calculated for the salty drink test. The results will be compared. Students will need to look for trends that indicate that the sugary drinks lead to a higher urine output change compared to the control than the salty drinks did to prove the hypothesis could be true. Otherwise the hypothesis is false.

True Lessons From Wallace Wattles’ The Science Of Getting Rich

Everyone wants to have money in his/her life, and there’s absolutely nothing wrong with that. We all want (and need) to have enough money to enjoy life and live to our fullest potential. But how do we get it? Many wise and successful people recommend to never be greedy, but to focus on abundance and “allow” money to come you. Never be fearful of poverty or lack; but instead, expect wealth as if it automatically comes to you.

Some people associate greed with having wealth. That is unfortunate. Having a greedy attitude is quite different from living as a wealthy person. To earn wealth, you will have to have control over your senses, and greed is an emotional response, not a controlled one.

Of course, no one can survive without resources and money. The Science of Getting Rich by Wallace Wattles sends an important message on how to obtain those resources – a message that many successful individuals have learned to live by.

Once of Wattles’ ideas was that, when you think and act in a particular way, it decides your financial fate. In other words, your actions and thoughts lead to your goals – even if it is not always clear at first. When you choose your destination, where you want to go, you need to be very careful. If you spend too much your savings would be depleted, i.e. you won’t have sufficient funds available when opportunity DOES knock at your door. So it is important that you are disciplined and develop self-control about spending.

Keep your expenses under control and stay focused on your goals. In order to become rich you will also need to have an awareness of your self, your strengths and weaknesses. Self awareness helps greatly in the long run, making it easier and more enjoyable to go after and achieve your goals.

Each time you face difficulties, remember, you’re getting closer to your goals. Difficulties show you your true path towards success. It doesn’t matter if the interaction was social or business, if you keep a positive mindset about getting rich, you will leave a positive impression on others – and on yourself.

You should feel that you are taking each step closer towards achieving your goals. When you visualize yourself inching closer and closer towards success, success never remains far from you. Whether it is money or fame, anything is do-able. Wealth and fame can simply become a part of your life, and work with you according to your needs.

Everyone born in this world has the right to become rich. But the correct steps need to be taken in order to become a wealthy person. We need to stay positive, correctly outline our goals and work very hard towards achieving success.
