Driving student interest in STEM subjects helps foster innovation for the future

In a world that is defined by rapid change - particularly in technology - there are concerns that students today won't be prepared for the challenges of the future. Of all U.S. high school students who graduated last year, only 45 percent were ready for college-level math and 30 percent for science, according to ACT, a college-entrance testing agency. As jobs increasingly require proficiency or expertise in STEM subjects (science, technology, engineering, and math), it's more important than ever that children are inspired to explore these subjects and understand their real impact on our everyday lives.



STEM drives an incredible number of the innovations we see today, from the fastest jet planes to the cars in our driveways to the televisions in our living rooms. Even the video and computer games that children and teenagers turn to for entertainment are based on STEM.



However, interest among students in these important subjects is lagging. And with the extraordinary number of careers and opportunities for growth in STEM fields, many organizations in both the private and public sectors are taking action to bolster student interest and enthusiasm in this area. Samsung, for example, is working to make STEM fun and exciting with their STEM education program called Solve for Tomorrow. It's a national contest that encourages teachers and students to creatively use STEM to explore and improve their local environment and community.



Our goal is to raise awareness and interest in STEM subjects, while providing teachers and students with the resources they need to innovate and grow, says David Steel, executive vice president of corporate strategy for Samsung Electronics North America.



We as a nation need to make STEM education a top priority, says Betsy Landers, President of the National Parent Teacher Association (PTA), who joined as a program partner this year. According to the U.S. Department of Labor, 15 of the 20 fastest growing occupations projected for 2014 require significant mathematics or science preparation. It is clear that making STEM education a priority is important, for our nation's short and long-term future. We commend Samsung for their efforts in making a difference in the education and lives of children.



As the world continues to change in unexpected ways, the demand for technological developments will only increase. By equipping students of today with knowledge and interest in STEM subjects, we're fostering the innovators of tomorrow.

Tips to improve your indoor air quality

(BPT) - You pride yourself on keeping a clean home. The laundry is washed, the dishes are dry and the den where the children built their pillow fort has been restored to sanity. You've been vigilant about cleaning up the messes you can see, but what about the messes you can't? What are you doing to improve the air quality in your home?



You may not think about the air quality in your home because the problem isn't visible, but that doesn't stop dust, dander or chemicals from polluting your air. Everyday living generates up to 40 pounds of dust in a six-room house every year, according to the National Air Duct Cleaners Association (NADCA), the HVAC Inspection, Maintenance and Restoration Association.



Taking steps to clean the air in your home will do more than just improve air quality; it will also save you money. Twenty-five to 40 percent of the energy used for heating or cooling a home is wasted because contaminants in the heating and cooling system cause it to work inefficiently, according to the U.S. Department of Energy.



If you're interested in improving the air quality in your home and saving money while you do it, here are some tips to get you headed in the right direction.



Hire a professional to clean your most important asset



Your heating and cooling system is the lungs of your home. The system literally takes air in and breathes air out. Because of this, keeping your HVAC system and your ducts clean is the most important thing you can do to improve your home's air quality. "If your ducts look dirty, they probably are," is NADCA's advice to consumers.



Have your system serviced by a certified technician. This will not only improve the quality of the air in your home, it will allow your heating and cooling system to run more efficiently, saving you money on energy bills.



Make sure to hire a NADCA-certified technician. All members have certified Air Systems Cleaning Specialists (ASCS) on staff and they are required to further their education by attending seminars and to adhere to the NADCA code of ethics.



Encourage ventilation



Today's newer homes are built air tight, making ventilation difficult. The simplest way to encourage ventilation is to simply open windows. In the bathroom, turn on the exhaust fan to stop steam from collecting dirt and keeping it in the bathroom. In the kitchen, place any appliance that creates steam or oily vapor under the stove hood. Finally, make sure vents on the outside of your home are not blocked by leaves or snow as season dictates.



Prevent mold



Mold can be one of the most harmful contaminators of air quality. You'll find mold in areas where moisture and poor ventilation come together. Vacuum rear grills on appliances like your fridge and freezer to improve ventilation and empty and clean any drip trays to eliminate mold. If you have a leaky pipe in your home make sure it is addressed. Take a tour outside and trim any bushes or shrubs that have grown too close as that proximity can lead to mold and algae.



Replace filters and screens



In the warmer months, clean the area around your air conditioner and repair any vermin screens on your chimney flues that may be damaged. During the cooler months, remove screens from any window that may trap condensation and make sure to change your furnace filter monthly.



Keeping the air in your home clean is just as important as washing the dishes or cleaning the clothes. The first step is to have your heating and cooling systems serviced by a NADCA technician. Once that is complete, follow these tips to maintain your air quality. To learn more about NADCA and how you can benefit from an HVAC cleaning, visit nadca.com/en/faq.

What lies beneath your dream home? New homeowners skip sewer line inspections

In a buyer-friendly market, home shoppers can be pretty particular in their search for a dream home. Increasingly, buyers are seeking flawless, move-in ready homes, and while traditional home inspections are a must-have, something equally important lurking beneath homes often goes overlooked.

A sewer line inspection is not included in the standard home inspection and is regularly waived in the purchasing process. Additionally, many buyers do not know that responsibility for the condition of the lateral sewer line leading from the street to the home lies with the homeowner, not a municipality. Buyers should reconsider including this important step before they sign a deal.

If a problem occurs, a sewer line replacement costs at least $4,500, but prices vary widely and costs increase dramatically by region, depending on depth and length of the underground pipes and if street repairs become part of the issue.

Experts at Roto-Rooter, North America's largest provider of plumbing repair and drain cleaning services, encounter this scenario far too often. Consumers, who just signed the dotted line on their dream home, soon find that they're trapped in an expensive plumbing nightmare.

"Just a couple of years after purchasing our home, we had a $15,000 sewer line disaster in our lap," says Jennifer Schappacher of Cincinnati. "The sewer line clogs began not long after we moved in, but as they became more frequent we had Roto-Rooter inspect the line with a video camera and only then did we realize the pipe had offset sections and a partial collapse that was causing sewage to back up into our house."

The Schappachers looked at only a few houses before deciding on one in a quiet shady neighborhood. It was charming with large, mature trees that shaded the entire street. But since the house was built in 1959, its concrete and clay underground sewer pipes were vulnerable to heavy root intrusion from the big trees. As those roots entered the pipe joints in search of water, they pushed the pipes apart and allowed surrounding soil to spill into the pipe, narrowing a 6 inch diameter pipe to just 1 inch in some sections.

Generally, a plumber can complete a sewer line camera inspection for $250 to $550, depending on the region. While not cheap, it's a relatively small price to pay when buying a home, especially if it helps a buyer avoid thousands of dollars in unforeseen repair bills.

To avoid unexpected and costly plumbing problems, the experts at Roto-Rooter recommend having a plumber conduct a video camera sewer line inspection, in addition to a standard home inspection, before buyers purchase a home. The process involves passing a waterproof fiber optic video camera through the pipe. The specialized cameras are equipped with bright LED lights so the inspection will reveal any cracks, breaks, offset or collapsed sections of pipe. The plumber will often provide a DVD copy of the inspection as part of the service.

"Sewer inspection camera equipment is expensive and often is only utilized by well-equipped plumbing companies, but the video inspection service itself is easy to complete and well worth the extra step," says Roto-Rooter master plumber Larry Rothman.

Root growth is the most common cause of sewer line damage and is often responsible for blockages and separated pipe sections. Outdated and eroding pipe materials are also a common culprit in sewer line deterioration. Older pipes are much more susceptible to root intrusion than new plastic pipe.

Inspections are especially important if:

* The home is 20 years or older.

* There are mature trees around the property.

* The home has been vacant for a period of time.

* The concrete surrounding the home is cracked or raised.

* There is considerable visible root growth in the yard.

Many homeowners, especially new homeowners, do not know or think about their home plumbing. For seasonal maintenance tips and general information, visit Roto-Rooter's plumbing basics section online at www.rotorooter.com/plumbing-basics.
