Hello, I have prepared a couple really fun science projects that any student can do at home with household items.

These Fun science projects should be done with adult supervision.

The first fun science project is called "The Balloon Inflater"

MATERIALS:

A carbonated soft drink in a bottle, a balloon, and a twist tie from a bread or a garbage bag.

WHAT TO DO: 1. Place the balloon over the mouth of the bottle and securing it to the bottle with the twist tie. 2. Have the adult hold the bottle and place their thumb over the mouth of the bottle covered by the balloon. 3. Now shake the bottle for five seconds and release your thumb. 4. The balloon fills with carbon dioxide that was dissolved in the soda pop. That's why they are called carbonated drinks.

This is a great fun science project that can give you that A you want in science class! Here is another great science experiment that anyone can do .

THE BALLOON ROCKET

MATERIALS: A balloon

WHAT TO DO: Simply blow up the balloon. Then, holding it between you thumb and forefinger, let it go and watch it fly.

EXPLANATION: You already know that the air escaped from the opening in which you blew up the balloon. You also noticed that the balloon flew in the opposite direction - this is action and reaction. The first force, air escaping, is the action. The balloon moving in the opposite direction of the air is the reaction.

We use this principle everyday. We push down on a chair to get up. We push our feet to the back to walk forward. A basketball pushes down onto the floor just before it bounces. You can probably think of many other examples.

I hope you have enjoyed these fun science projects. Please remember that these science experiments should be done with adult supervision.

Fun Science Projects

An alarm is being raised about global warming causing dramatic rises in the temperature of ocean waters. Scientists are studying warming waters all over the globe to determine the extent of this rise in temperatures.

The consequences of global warming are far-reaching. One of the most devastating effects of global warming is an impact on tropical storms. Hurricanes that would have been category 3 storms in years past are now category 4 or above because they are energized when they pick up warmer-than-normal ocean water. There has been a significant increase in these higher intensity storms over the last 35 years. In 2005, the Atlantic was bombarded with 27 tropical storms powerful enough to receive a name, and fifteen of them developed into hurricanes. Five of these storms were classified as category 4 hurricanes and four reached the level of category 5. Hurricane Katrina made a terrible mark on history in August of 2005. It became the costliest hurricane in American history and also one of most lethal.

Earth's ice is crucial in order to maintain the delicate balance in the environment. As global warming causes temperatures to rise in the oceans, glaciers and icecaps are melting more rapidly. One particular ice shelf in Antarctica, the northern section of the Larson B shelf, collapsed in recent years. Scientists suddenly realized how fast the ice shelf could disintegrate. The polar ice cap is dissolving at an astonishing rate as well--9% per decade. This recent phenomenon is a definite cause for alarm. In the last half century, the thickness of ice in the Arctic has decreased by 40%.

Perennial sea ice in the Arctic has been receding as well. In 2005 there was a record low in square miles of sea ice. Just two years later, in 2007, the record was broken again with half a million square miles less perennial ice than in 2005. Some scientists predict that all the sea ice will be gone by 2040.

Melting ice will also cause sea levels to rise. When this happens, islands are lost and coastal communities are flooded. Various suggestions have been made about the levels that the water could reach, anywhere from 10 to 23 inches by 2100.

Global warming has the potential to make the earth a very inhospitable place to live. Rising temperatures in ocean waters are a clear indication that the process has begun. With the melting of ice in the glaciers, icecaps, and on the sea, it is a matter of time before global warming has even more harmful effects. It is up to the people of the world to do what they can to stop or slow this alarming environmental problem.

Knowledge is the key to solving problems associated with the Climate Change and Global Warming situation. You can get more information at http://www.globalwarming-101.com
