When NASA was looking for ways to purify air in space stations, they studied plants. Common houseplants freshen indoor air by removing toxic chemicals.The studies looked at several representative kinds of toxins: formaldehyde, benzene, tricholorethylene, ammonia, carbon dioxide and nitrogen dioxide.

Though all plants probably have some filtering ability, the following plants did the best job in combating indoor air pollution:

Heartleaf Philodendron – Philodendron scandens ‘oxycardium’
Elephant Ear Philodendron – Philodrendron domesticum
Cornstalk Dracaena – Dracena fragrans ‘Massangeana’
English Ivy – Hedera helix
Spider Plant – Chlorophytum cososum
Janet Craig Dracaena – Draceaena dremensis
‘Warneckii’ Dracaena – Dracaena dremensis
Weeping Fig – Ficus benjamina
Golden Pothos – Epipiremnum aureum
Peace Lily – Spathiphyllum ‘Mauna Loa’
Selloum – Philodendron selloum
Chinese Evergreen – Aglanema modestum
Bamboo Palm – Chamaedorea sefritzii
Mother-in-law’s Tongue – Sanseveria trifasciata
Red-Edged Dracaena – Dracaena margnata
Gerbera Daisy

Spider plants are good at removing carbon monoxide and nitrogen dioxide.

The best plants for removing trichloroethylene (found in paint, varnish, adhesive and ink) are dieffenbachia, English ivy, gerbera daisies, chrysanthemums, peach lily, bamboo palm, Dracaena Warnecki, and mother-in-law’s tongue.

Formaldehyde is most effectively removed by spider plants, bamboo plams, golden pothos, peach lily, Dracena Maginata, Dracena “janet Craig”, mother-in-laws’ tongue and philodendrons. Think of these plants when you get new furniture or are remodeling.

Painting? Benzene is in paints and oils, and is used as solvents. The best plants to remove benzene are dieffenbachia, English ivy, gerbera daisy, chrysanthemum, peach lily, bamboo palm, Dracaena Warneckei, and mother-in-law’s-tongue.

One plant cleans about 100 square feet. About 15 planst in six inch posts will be enough for a home under 2,000 sq. ft.

Google: how to test indoor air pollution and you will find many instruments to measure your air quality for a science fair project.

Question: Dear Madeline

Some time ago you had something in one of your newletters about a science fair project dealing with chocolate. (coffee, cacao etc.) that one can use. Is it possible to forward the information to me. We would like to do something along that line for our next project. My Child is 12 years old.

E Leonarde

Answer: Elbie, I honestly don’t know where it is at.
There are about 5000 pages on the site and I hired a professional science writer
who just got her Phd to write the articles.

Go to and use the search button,
put in the word coffee, then try cacao if you cannot find it.

Here are a couple that I found. You may be able to find more:

This week we are going to be looking at the National Energy Education Development Project Youth Awards Program. While this is not a science competition, per se, it is a way for schools to recognize outstanding students for their science achievements. The focus of this program is classroom science exploration. It is designed to encourage schools and students to explore energy science in the classroom and then apply the lessons learned to the community.

This year’s Youth Awards Program will be held in Arlington, Virginia from June 20 through June 23. The application deadline for this program is May 12, 2008. In addition to submitting your application fee of $525 per student, your application and your release forms, you will also need to secure a nomination from one of your state’s senators.

The registration fee of $525 is going to cover most of the student’s expenses during their trip to the Youth Awards Program. It will cover their lodging, their local transportation, their meals, and their tour of Washington, D.C. This is a great program that helps to recognize superior science students, to reinforce the value of developing science skills and a great chance for kids across the country to network with one another. Participation in this program also looks great on college entrance applications.

Science is an important subject to do well in. If you want to get into a great college or technology school development program, then you can develop your skills by working with middle school science fair projects, high school science fair projects and fuel cell car experiments science kits.

Question: How are you today? I need to know do you have any science fair project kits on ROCK SLIDES for grade 9. Kenny

Answer: Have you considered doing a science fair project on how gravity contributes to rock slides?

Another possibility is to do a science fair project on how global warming is affecting the glacial slides along with the rocks that are embedded in them. This is called iceberg claving. You can read all about it on the Science News For Kids website.

image of MadelineI know when its science fair time because e-ons of emails arrive every day from parents, students and teachers:

Will you send me a science fair project?

What is a good science fair project that my daughter can do for her 7th grade science fair?

Do you have easy science fair projects on your site?

Do you know where I can find ….

Well, now we have created a Forum for you to share your science fair experience, ask questions and get answers from each other. This is a blog for students, parents and teachers… a place for you to help each other.

Each post is monitored and will be posted after it is read by an adult. So please keep your comments honest, clean, and helpful. This is an educational site. The purpose of the Super Science Fair Projects blog is to help you to create the best science fair project on the planet! It is not a place to visit with your friends or to joke around. Those posts will be deleted.

By subscribing to the Free Science Fair Enthusiasts weekly/monthly newsletter where you will be kept informed of new information posted on this Forum.

We look forward to your input.
