Difference in Density of Adjoining Water Masses

You have learned what happens when two adjoining fluid masses differ in density. The denser mass sinks beneath the less dense mass.

The densities of water masses depend on two factors: (a) temperature and (b) salt content. Consider the four water samples at right. Their volume is expressed in liters, temperature in Celsius degrees, and salinity in parts per thousand (%0).

Size

How large is the object? Size is described subjectively by "large and small" And objectively by dimensions. But a description is more likely to meaningful if it is comparative. For instance, "The boo, nine by six by three inches thick, (9x6x3), is the same lenght and width as your textbook but more than twice as thick" is more descriptive than either of the following. "The book is a large one" or "The book is 9 inches by six inches by 3 inches.

Hands Up!

In our daily lives, our hands sure come in handly. We use them to draw, play instruments, make crafts, and even just greet each other with high-fives! Since most of our actions involve our hands, we think its time we give a big hand to our hardworking hands.

Women's Day

Month's to recall. Month of March is a Women's Day. Remember that on all march day serve as a reminder of the fields in which women must still battle for fundamental rights, and where they remain victims of violence and enduring inequalities.

Oryza Sative or Rice

Rice is very dear to Asians. For over 7,000 tears it has been cultivated. Scientist from the world over work hand-in-hand in developing fast-growing and highly yielding varieties which are resistant to diseases.

Rice after all is food for over 700 million people.

Isn't it?

Cloud

Cloud is composed of particles of liquid water or ice which are so tiny that they remain floating in air.

Clouds are formed by the cooling and condensation of layer of moist air appears as sheets or layers.

Meteorology

Meteorology is a branch of science that deals with the study of weather on a day-to-day basis. Weather is the generally condition of the atmosphere over a particular place was probably made by meteorologist. A meteorologist is a person who studies the weather. Meteorologist needs many kinds of data before the weather can be predicted. The ability to make accurate weather forecast is directly related to the speed at which large amount of data can be analyzed. This is where the greatest advances have been made during the past few decades. By contrast, the accuracy of measuring instruments has not changed greatly.

Energy Conservation

Is any behavior that results in the use in the less energy. It means wise and efficent use of sources. It is necessary to conserve energy come from nonrenerable. Energy can be saved by having a properlifestyle. Energy conservation also means pollution is reduced.

The Activities of Science

You may not realize it, but science is all around you. You encounter science in the performance of your daily activities. For example, when you "make a guess" about which brand of soap is best suited for your type of skin. then "test" different brands of soap, and use you "observation" to choose and right brand, you are following a method of solving a problem. When you try different ways of serving a volleyball to throw it across the other side of the court, you are testing different solutions to a problem. These are just some examples of science activities you do in your everyday life.
