The weather is all around us, all the time. It is an important part of our lives and one that we cannot control. Instead the weather often controls how and where we live, what we do, what we wear and what we eat. Someone who studies the weather is called a meteorologist. Weather predictions are made by forecasters who you see on television.

Weather Definition
Weather is the day-to-day conditions of a particular place.For example: It was raining today at school. Yesterday it was sunny at home.

Blind Faith vs Evidenced-Based Trust

Isn't science just a theory?

The Stars at Night....

Hetrzsprung and  Russell independently made an interesting observation in 1912 when they attempted to correlate the spectral class of a star with its absolute magnitude. They discovered that 90% of the stars in the Universe fall within a narrow band called "The Main Sequence." They noticed that as a star's surface temperature increased, so does the absolute magnitude. Bluish stars shine brightly, and reddish stars shine more dimly.

To put thing into perspective, consider that to light our sky to the current level with a low end M class star, we would have to be 1000 times closer than we presently are to the Sun, or a mere 150,000 km. At the high end of the O class, we would have to be 200 times farther away than we are now, or at a distance 5 times greater than that of Pluto. This relationship is shown in the chart below, and is called the HR Diagram. It is THE most important diagram in all of Astronomy for it holds the clues to the evolution of all stars, including our own.

The Sun King and Scaled Solar Systems

How Big is the SUN?

Using a Tube to Measure the Sun

How wide is the sun?
The Sun is 875,000 miles across, though scientists usually use kilometers, in which case it is 1,392,000 kilometers across. It is also very heavy. To write its weight in kilograms (1kg = 2 pounds, more or less) you write 2 followed by 30 zeros!
Sarah Gibson
how much does the sun weigh?
The Sun is about 2,000,000,000,000,000,000,000,000,000,000 kg (a 2 with 30 zeros kg, or about 4.4 with 30 zeros lbs). Maybe you learned in your physics class what's the difference between weight and mass. For example a person of 50 kg weighs 50 kg on Earth, 8.3 on the moon, and 1354 on the Sun.
Mandy Hagenaar
How big around is the Sun?
The radius of the Sun is about 700,000 km (435,000 miles). As you know the circumference of a circle is 2 pi r, where r is the radius. That makes 4.4 million kilometers (2.7 million miles) for the circumference. For comparison, the circumference of the Earth is about 40,000 km (25,000 miles), about 100 times smaller than the Sun.

Make a scale model of the Solar System and learn the REAL definition of "space."

MIX DRY: Scientific Experiments

How to Graph Using DRY MIX

Lots of information about variables and controls that you need in math as well as every experiment and lab report. MIX DRY is an acronym to help you remember how variables are plotted on a graph. It also serves as a reminder that there are two names for each variable because scientists have not reached an agreement yet.

M = manipulated variable I = independent variable X = graph information on the horizontal axis

D = dependent variable R = responding variable Y = graph information on the vertical axis

Independent Variable or Manipulated Variable is what you are testing. It is what causes things to change as you make changes to it. Some people nickname it the I-do variable.
Dependent Variable or the Responding Variable is the effect and it may or may not change. It is observed during as well as at the end of the experiment.

Controlled Variables are not graphed, but these could affect the results of the experiment. It is free of any change of the independent variable. Have as many controlled variables as possible to add validity.
Extraneous Variables are not graphed. They are unanticipated, unwanted events, which may cause incorrect experimental results and wrong conclusions.
