Stars are giant balls of gas that produce light and heat through nuclear fusion reactions in their cores. Astronomers can determine properties of stars like temperature, luminosity, and composition by analyzing their spectra. Stars evolve over their lifetimes, with more massive stars having shorter lives and ending as supernovae. Galaxies contain billions of stars and come in spiral, elliptical, and irregular shapes. The universe originated in a massive expansion known as the Big Bang around 13.8 billion years ago.

This is a presentation that I completed for EDU 290 in the Fall 2009. The intent of the assignment was to create a lesson that could be used by a student that missed the classroom instruction due to illness
That's my lesson plan about earth layers... hopefully it can help you to find your idea...
Don't use the assessment form because it's not really effective to assess your teaching and your student ability... :D

Marvin neemt je in deze presentatie mee in de voordelen van non-endemic advertising op retail media netwerken. Hij brengt ook de uitdagingen in beeld die de markt op dit moment heeft op het gebied van retail media voor niet-leveranciers.

Unveiling the Secrets How Does Generative AI Work.pdfSam H
ย
At its core, generative artificial intelligence relies on the concept of generative models, which serve as engines that churn out entirely new data resembling their training data. It is like a sculptor who has studied so many forms found in nature and then uses this knowledge to create sculptures from his imagination that have never been seen before anywhere else. If taken to cyberspace, gans work almost the same way.

16. Characteristics of Stars Size: anywhere from 20km to 1 trillion km in diameter Mass: the amount of matter Color: stars can be red, blue, white, orange or yellow Composition: contain different elements determined using spectra
17. Characteristics of Stars Temperature: Blue is the hottest (35000 ยฐ C) Red is the coolest (3000 ยฐ C) Yellow (our sun) (5500ยฐC)

20. Star 1 High luminosity Far from earth = lower apparent magnitude Star 2 Low luminosity Close to earth = higher apparent magnitude Apparent Magnitude v. Luminosity
21.
22. Kinds of Stars super giants- largest of all stars, very luminous red giants- cooler, large, very luminous dwarf stars- less luminous, red, orange or yellow white dwarf- very faint, small and dense
23. Variable Stars- vary in brightness over regular periods or cycles 2 types: A. pulsating change in brightness as they contract (brighter) Or expand (dimmer) Example: cepheid - yellow supergiant
24. B. nonpulsating Eclipsing Binary 2 stars of unequal brightness that revolve around each other brightness depends on which one is in front of the other
25. Pulsars star that releases light and radio waves in pulses may be the neutron star formed in a supernova it looks like it pulses because it is rotating , like a searchlight
30. Life Stages of Stars With Solar Masses less than 8 Solar Masses
31. Main Sequence Star (Our Sun) โ >90% of all stars >The star is stable >Burns Hydrogen gas to Helium in its core through nuclear fusion > The energy released causes the star to shine. >Stars spend about 90% of their active lifetime as main sequence stars. Red Giant โ >The star begins to run out of fuel and the core begins to shrink >Helium turns into Carbon >Rapid burning of helium causes outer layer to puff out, cooling the star >The star turns red
32. Planetary Nebula โ >Outer layers are ejected as core continues to shrink >Shell of hot gas >Core is exposed White Dwarf โ >Low mass core continues to shrink creating a white dwarf >Surrounded by the Planetary Nebula
