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.

Too Much Stimulation With Today’s Technology

Is there anything more annoying than that person standing ni front of you in a grocery store or checkout line babbling away on a cell phone while a kind salesperson is trying to help them? The cell phone person nods and points directions at the clerk while enjoying a riveting conversation over nothing. There is nothing more annoying and we won’t even discuss people who miss green lights because of their nonsensical cell phone ramblings.

Turn off the cell phone and turn off the laptop and any other portable device you may be carrying with you. There is a certain amount of excitement and adventure in being inaccessible. It can be a little bit scary at first, not being on the grid, not being in constant communication with everyone on the outside world, but it is necessary to do once in a while to regain your sanity.

People have become so reliant on today’s new technology that personal communication has dwindled to nothing. How many times are you on vacation and someone has to dart back to the hotel room to check on the laptop to make sure no important messages were received on the e-mail? There’s a reason to take vacation, but now the new term is “working vacation.”

If you can just stay away from the cell phone for a few minutes, take a walk around the mall and you will see how many mindless drones are babbling away on their cell phones or texting their friends who are likely in the same mall at the same time. It gets to look ridiculous. If you invite friends with kids over to your house, place a ban on use of your computer or they will just sit there avoiding family time to message their friends.

Everybody needs some time to themselves and nothing short of an emergency is worth so much that it can’t wait a few hours. If you check your Facebook pages, chances are that 99 percent of the messages are just gibberish being written by people with nothing better to do. Take some time away from technology and enjoy life.

Importance Of Science Lab Equipments For Education

Science stands out distinctively from other subjects because of its nature of validating things through experiments. It is through scientific instruments or equipments that experiments and observations are carried out. Scientific instruments are set of tools, kits, apparatus and devices which are designed for certain purposes. These instruments include devices like microscope, Bunsen burner, test tube, thermometer, beaker, etc. They are used in various fields such as, medical, production, educational and research.

Science lab equipments are those equipments used for bearing and dealing chemicals. These devices are important for scientific purpose as they help in carrying out experiments safe and successful. Tools like test tube holder, weighing machine, test tube stand, compass, flask, funnel, etc. are some of the examples.

Importance of Educational science lab equipments

Educational laboratory equipments offer students the opportunity of learning science through hands-on experiences and enhancing their learning and thinking skills. These equipments will help the students to be more competitive and help achieve their goals through higher level of education and thinking order.

Schools that are well equipped with scientific lab instruments will give the students greater opportunities for learning. For instance, students can learn with practical experiments in the school laboratories about the scientific methods such as collecting data, experimenting and testing hypothesis. Making available with real lab equipments will make the students more enthusiastic and appreciative towards science and its findings.

Laboratory scientific instruments make the environment of interactive learning possible. Science is a discipline where conventional classroom teaching is not enough and it becomes effective only when teachings are accompanied by creating experiments and deducing conclusions from the experiments.
