HR-diagrams
What does the x-axis on the HR-diagram tell you about a star?
Stellar class or temperature.
Is oil, biotic or abiotic?
Abiotic.
What is the first stage in a main sequence star's life cycle? Like how does it begin (Think of it as a toddler)
Protoplanetary nebula
What are two types of diffuse nebulae?
Emission nebulae and reflection nebulae.
Pick a number between one and four.
You each get 500 points, but then you give all your points to the number you chose:
1= Blue
2= Pink
3= Orange
4 = Green
:) everyone wins!
What does the y-axis tell you about a star on the HR-diagram?
Magnitude or luminosity / absolute magnitude or apparent magnitude.
List three abiotic factors that may affect an ecosystem.
water, wind, space, light, temperature, earthquakes, volcanoes etc...
What is a red giant or a red super giant fusing together?
Helium atoms into heavier elements.
Which two nebulae appear most in the life of stars? They play a role.
Protoplanetary nebulae and planetary nebulae. Double points if you included supernovas.
¿Qué le dice un pato a otro pato?
Vamos empatados
Where are white dwarfs found on the HR-diagram?
Bottom left corner
List two biotic factors that may affect plants.
How are massive stars and main sequence stars different AFTER they stop fusing elements?
Main sequence stars produce a planteray nebula and massive stars produce a supernova.
Diagram the evolution of galaxies (use your notes). 1 minute.
Must include irregular to spirals (both bared and regular) then to elliptical galaxies.
¿A dónde van las pulgas cuando se mueren?
Al pulgatorio.
Where is our sun located on the HR-diagram (draw it)
... needs to be close enough.
Giraffes are believed to have adapted to growing plants and they developed longer necks. Is this an example of an abiotic or biotic factor?
Biotic.
What is a white dwarf fusing?
Nothing. It is cooling off.
Double points!!!
which wavelengths have the highest frequency?
Gamma rays.
Diagram this joke. Best ones win. 1 minute.
¿Sabes qué le dice un jaguar a otro?
¿Jaguar you?
Triple points!!!
Luminosity, stellar class/temperature, Main sequence stars, white dwarfs, red giants, super giants.
you have one minute.
TRIPLE POINTS!!!
What is biodiversity?
Double points!!!
What type of star is our sun? How does it compare to other stars (size and temperature), and what number represents it on the luminosity side of the HR-diagram?
500 pts - Main sequence star
1k pts - main sequence plus average size and average temperature.
1.5k - main sequence plus average size and average temperature plus 1 on the luminosity side of the HR-diagram... and double points!!! (3k technically)
Which wavelengths have the lowest frequency?
Radio waves.
Dice game.
Blue vs green winner gets 500 pts, loser gets to spin for the win.
pink vs orange winner gers 500 pts, loser gets to spin for the win.
Losing teams may choose to swap scores with whichever color the spin landed on.
