eight grade science exit project?!?!?!?!?

Question

is this a good science problem to do a science project/report/exit project about?

problem: what are different kinds of stars?

Answer 1

Stars are mainly huge balls of gas held together by gravity that give off light and heat. But there are also many different kinds of stars. Stars have different colors, sizes, and temperatures.
Stars are grouped together by what astronomers call spectral classification. This groups the star by it's color, composition, and size. For example, an O type star has a color of blue and it's temperature is 70,000 degrees Fahrenheit. A B type star is blue-white and is about 33,700 degrees Fahrenheit. An A type star is white and is about 15,000 degrees Fahrenheit. A F type star is also white but it is about 12,000 degrees Fahrenheit. A G star is yellow and is about 9,400 degrees Fahrenheit (the sun is a G star). A K type star is orange and is about 7,200 degrees Fahrenheit. Finally, a M type star is red and is 4,900 degrees Fahrenheit. As you see, the duller the color of the star is, the cooler it is.

Answer 2

yes it would make an interesting report as there are a few different types that are known (there may be some we have not discovered). I do know some yellow, white dwarfs ,red dwarfs, red giants,and blue dwarfs and giants. Not sure if they count nebulas. Also black holes are considered dead stars that collapsed on themselves.

Answer 3

Leaves are style of like photograph voltaic panels. you ought to instruct how a leaf acts a photograph voltaic panel in that it converts photograph voltaic power into use able power (via a technique referred to as photograph-synthesis). wish that facilitates.

Answer 4

For eighth grade, sure.
