A Fifth Grade Science Project can be one of the most fun school projects that a parent and child can do together. Here are some really good science project ideas that our family has done. The projects are easy to do, yet they meet the requirements of most science fairs and most fifth grade teachers. Check out the ideas, and find out how to get step by step instructions at the end of this article.
These are investigative science projects, which involve a science experiment:
o Does the shape of ice affect melting time? Use the same amount of water, place into different shaped containers and freeze. Then see how much time each piece of ice takes to melt.
o Which toilet tissue is most biodegradable? Take samples of different types of toilet tissue, and soak them until they fall apart. Run the samples through a strainer, and see which sample leaves the most paper undissolved.
o Which citrus fruit has the most Vitamin C? Make an indicator solution with iodine and starch (it's EASY to do!), and test samples of citrus fruit or juice to see which one has the most vitamin C.
o Which brand cereal stays crunchy longest? Weigh different brands of the same cereal, soak in water, and then weigh again to see which one absorbed more water.
These are demonstration science projects - when your teacher wants you to demonstrate a scientific principle to the class.
o Demonstrate that yeast gives of gas. Place a yeast and sugar solution into a bottle, put a balloon on top, and watch the yeast give off gas so that the balloon blows up!
o Demonstrate how static electricity works. Make a ball of aluminum foil dance between your finger and a pie plate. Watch this one on www.youtube.com/watch
o Demonstrate how chemical reactions can be sped up. Put alka seltzer into a cup, and watch it fiz. Then do it again with crushed alka seltzer, another time with warm water, and yet another time with TWO alka seltzers.
We've done all of these science projects with our four boys, and they are fast, affordable, and easy to design on your own. We also provide illustrated, step by step instructions on these projects at our website! Whatever you do, remember, fifth grade science projects really can be fun and a learning experience at the same time. So grab your slide rule and your test tubes, and get started on your project now!
Did you know about 35 million Americans are suffering from one kind of lung disease or the other? Did you know that lung infections are believed to be one of the most important causes for infant mortality in America? Probably you also did not know that diseases related to lung claim one in seven lives every year. Well, it is an alarming statistics, isn't it? But what does a lung disease mean? Precisely, Lung disease refers to any kind of disorder in which the functions of respiratory system get affected and impaired and this impairment manifest in several ways, such as, troubled breathing, nagging cough, short of breath, pain or uneasiness in the chest, inability of taking up physical labor and likes.
The medical science divides all kinds of lung diseases into two broad categories: Obstructive lung diseases and Restrictive lung diseases.
In obstructive lung diseases, the airways get narrowed or blocked and the result is a decrease in exhaled air flow. The disorders like Chronic Obstructive Pulmonary Disease (COPD), emphysema, asthma, and bronchiectasis are cause by such obstructions of lungs.
Restrictive Lung Diseases result into either loss of lung tissue or decrease in the lung's ability to expand. It may also decrease lung's ability to transfer oxygen or carbon dioxide into the bloodstream. The killer disease of lung cancer is a kind of restrictive lung disease. Pulmonary fibrosis and pneumonia are also caused by the same lung disorder.
Probably lung cancer is the most common form of ling diseases that the people are more familiar with. Another commonly found diseases among Americans--asthma-- is also a kind of lung disorder. Tuberculosis is also the result of bad lungs. Then you might have heard of such diseases like Cystic Fibrosis, Emphysema or Mesothelioma...they all are the manifestation of some kind of lung disorders.
Are you a heavy smoker? Well, you run the maximum risk of developing lung disease. What did you tell, you don't smoke? Well this is not adequate; you have to stay clear of the smokers, for it is the passive smokers who are at higher risk than the smokers themselves to develop some kind of lung disease, even cancer. Make it a point to request a smoker to enjoy his cigarette in a secluded place so that the others are not forced to inhale second hand smoke.
Then if you work in mines or somehow exposed to radon gas, you run the risk of developing a bad lungs. In the USA, radon is sometimes found in the households also and so it is important for everybody to invest in a kit for measuring the concentration of radon at your home and take the steps accordingly.
If you are working in the sectors which use asbestos, you are required by the Federal Law to use protective gears including a face mask. The same is necessary if you are constantly exposed to dust or harmful chemical fumes, for these also considerably damage your lungs in the long run.
Last of all, the medical authorities always recommend a healthy diet for preventing lung cancer. A diet consisting lots of anti- oxidant rich fresh fruits and vegetables, considerably reduces the risks of cancer. Also go for regular Spirometry testing to make sure that your precious lungs are in perfect shape.

When uranium in American soil decomposes, it creates radon. This is bad news for families when the gas seeps in through the cracks of your basement and floorboards. Too much exposure can lead to lung cancer, and radon is responsible for more than 20,000 lung cancer deaths in the U.S. Annually.
When radon levels in a house are too high, I have seen people reduce them by 90%+ just using the simple steps in this guide. If you do it right, you can avoid exposing yourself to high levels of radon in the process.
1. Get a commercial radon testing kit and see how high your levels are.
2. If the levels are 4x the safe levels in your state or more, stop right there. Google a "radon mitigation professional" in your area and have him come do the work. It's simply not worth the risk if the levels are that high.
3. Ensure that you're getting enough air circulation through all the close and compact areas in your home, such as your basements and crawl spaces.
4. Aerate your home further with vents and fans. Put in ventilation fans in your home anywhere radon levels have accumulated and are particularly high. Open up all your chimney flues and make sure you let stale air waft out of the home by opening and closing doors.
5. Look for ways to generate cross-draft in your home by opening adjacent doors. For example, you may have a second doorway to your backyard through the kitchen. Open that door up and the front door. Put a fan facing out of your home in the direction of the cross-draft to get that stale air out of your home.
6. Seal off the cracks in your walls and floors. These gaps are your entry point for radon gas.
7. Seal off all open plumbing bores and seal your wall seam to the floor. Any area in your home that lacks a complete join is a candidate for sealing.
You want your family to live a long, healthy life, and so do we. Make sure your home is radon-free with these DIY radon mitigation techniques. Remember, if you cannot reduce your radon levels dramatically by yourself, make sure you get a professional. Ignoring radon will NOT make it go away.
