Earth Hour : Turn off the lights

Science is almost always associated with electricity. In fact most scientific discoveries are based on science projects using electricity. The trouble is that not everyone regards electricity as the miracle it is any more. We have got so used to turning on a switch and flooding a room with light that the magic has gone out of the experience.

Maybe we have taken electricity so much for granted because we have grown up with it. Secure in the knowledge that we have to but hit the switch and lights will follow. The fact that a majority of the world’s population still does not have electricity in their homes is of little importance to us.

That’s why the Earth Hour project is important. Over 80 countries on all the continents in the world participated in the last Earth Hour event. At an appointed time every one switches off all the lights in their homes. It is an awareness drive for Global Warming being caused by human activities. So make sure that you do your part for the Earth next time we celebrate Earth Hour.

On the other hand science projects like this one on light intensity here will never be possible with out electricity. So make sure that you try it out when you can use electricity. Just make sure that you use it without wasting it. As with all man made resources even this one is non recyclable.

Flying in the Air : At the Science Fair

Any number of kids want to fly. In fact many adults too have this secret fantasy.  All of us are fascinated by birds that effortlessly flap their wings and take off into the sky.The blue open spaces seem to symbolize freedom to us. There is something very liberating to imagine yourself soaring through the air.

Perhaps that’s why the sport of paragliding or para sailing are so popular. Although what goes up, must come down. In some cases it can be aided by parachutes. In other cases it will crash down to the Earth. Many science experiments go into designing and manufacturing good parachutes. This is an essential safety equipment for any one who is going to fly in a plane or even jump out of one.

Here’s a good science fair project idea based on the study of parachutes. This will help you make a detailed study of parachutes made out of different materials and just how effective and fast they are. These are just guidelines and you are free to improvise as and when you feel the need.

You never know it could actually lead you to design the next best selling parachute. It is through small science projects like the ones that you do for your science fair projects that you can lay the foundation of your future career. And even if it does not work out into a job, you would still have had fun with the science experiments.

Arctic Ice Meltdown : Science Projects for a Submerged Earth

Thanks to global warming the ice caps in the Arctic and Antarctic regions have been melting faster than ever before.  This is affecting the level of water present in the oceans.  Also the white surface of snow reflects the sunlight back to space, this helps keep earth cooler. While the dark ocean water surface absorbs more heat, making the Earth a warmer planet.

This in turn makes the ice melt faster. So you have low lying landmasses getting submerged. Countries like Bangladesh which are barely a few feet above sea level will see a sharp reduction in the area of land available to them. Sure you can build dams like the Dutch, but how long will the sea stay back? Is the sea going to rise and swallow us all up? No its not that bad, as yet.

Although it would be a good idea to learn how to swim. The water in the polar ice caps is going to be released slowly into the sea and one day we will not have snow any more. The Earth will be a hot and humid place and many of us may be living in boats and floating  to work in cannoes. Till that happens it may be a good idea to get comfortable with water.  Build your own miniature submarine and enjoy the dangers of the deep!

Clean Water Dirty Water : Science Project Idea

How lucky are you to be able to drink clean water each day of your life? Very lucky indeed. Do you know that even today many countries do not have safe drinking water available for their children to consume? That some places tap water is likely to give you diseases such as Malaria, Cholera, Typhoid or Dengue?And that’s if you are lucky to have a tap in your house as there are homes that get no running water supply at all.

In fact to illustrate just how much dirty water can affect you, recently Dirty Water Vending Machines were placed in Manhattan. You could for a dollar buy water that “contained” the germs of all these different diseases. This awareness campaign is being run by the UNICEF. The money collected goes to the UNICEF fund.

So make sure that you are not wasting all that lovely clean water that runs in your tap at home. Open the taps for just as long as needed and use the water judiciously. Remember that there is a child in the world who is not as lucky as you and has to walk ten miles to get a drink of water from the well near by.

Speaking of water, what about an experiment with another liquid that we all like, Soda Pop. This is a fun science experiment that can also be used as a science project. Have fun trying it out.

Water on the Moon : Science Experiments

Recently NASA  revealed that India’s maiden lunar mission, Chandrayaan-I, had traced water molecules on the moon’s surface.  This caused all kinds of ripples of excitement all through the scientific community. What’s the source of this excitement? Why are all kinds of dignified grown ups acting like they are four and have been given a huge bar of candy?

The moon has always been considered a hostile environment for human beings like us. It was believed to be dry and arid thanks to having no atmosphere. It was considered impossible for life as we know it to survive on the moon. Even though it is our closest heavenly neighbor, humans could not believe that it would ever be possible to actually survive there for any length of time.

Now if water exists on the moon what possibilities does it open up for us on Earth? The water molecules can be split to create oxygen. Maybe we can have a science project involving getting the moon an atmosphere.  As land gets consumed by urban jungles, perhaps land on the moon could be brought under cultivation to grow food for us.  The possibilities are mind boggling. If all this talk about the moon makes you want to blast off into outer space, try out this science project idea on Rockets till you are grown up enough to get to the real deal .

Welcome Science into Your Life

Whether you know it or not there is a lot of science around you. Science projects have helped develop bare ideas into bone and flesh from many devices. Some think of science as a “Good servant but a bad master.” Yet no one can deny that the application of science over the years has led to technology that makes our lives very comfortable indeed. So where do you find science in your life? Just about everywhere.

I’m not talking about the elcetronic gadgets that you use each day. They are too obvious an example of scineca nd technology. No I’m talking about the mundane things that are lying around the house. Things that you would never even associate with science and technology.

There is science in the bed that you sleep on. The wood used to build your bed was probably cut using an electric saw. The nails and glue that hold the bed together in the structure that it is, were developed by exploiting the scientific properties of these materials. Imagine the amount of science involved in making that little nail out of iron. Iron that was probably extracted from a deep lying ore in the ground, then purified and finally shaped into that nail.

As you can see just about everything that you use has been brought to you by a number of scientific experiments. So its now your turn to welcome science into your life. Let it glow and then share the glow with all your friends.
