WEEKLY EXPLORATIONS...

QUESTIONS: 

What are some factors that make some stars brighter than others?

What are some factors that make some stars appear brighter than others?

What effect does DISTANCE from earth have on the APPEARED BRIGHTNESS of stars?

What causes some STARS to BE BRIGHTER? What causes some STARS to APPEAR BRIGHTER (even if they are not actually as bright as another?

What are some characteristics of our sun? How does our sun compare to other stars?

Discuss: Why is it important to study the sun?

In-Class:

 Monday

QUESTION:
We went over the unit 3 science test on Matter - returned and went over questions

What effect does DISTANCE from earth have on the APPEARED BRIGHTNESS of stars?
1. Research Vocabulary terms - define "apparent magnitude" and "absolute magnitude" on green cards

Assignment(s): 

1. Science Test corrections due Wednesday (if you choose to do them)

2. TYPE your paragraph you wrote for today about how stars are SIMILAR & DIFFERENT into Google Classroom (due WED)

Tuesday

QUESTION:

What effect does DISTANCE from earth have on the APPEARED BRIGHTNESS of stars?
1. Go Over Vocabulary terms - define "apparent magnitude" and "absolute magnitude" on green cards
2. Brainstorm, Share, Establish our Driving Questions for this lesson...

3. STUDENT ACTIVITY: Collecting a STAR Sample and making a frequency diagram and a bar graph comparing (appeared) STAR SIZE 

Assignment(s): 

1. Science Test corrections due Wednesday (if you choose to do them)

2. TYPE your paragraph you wrote for today about how stars are SIMILAR & DIFFERENT into Google Classroom (due WED)

Wednesday.

QUESTIONS:

What effect does DISTANCE from earth have on the APPEARED BRIGHTNESS of stars?

Turned in science test corrections...

1. FINISH STUDENT ACTIVITY from yesterday: Collecting a STAR Sample and making a frequency diagram and a bar graph comparing (appeared) STAR SIZE 

2. CLASS INVESTIGATION #1: We will use flashlights to model two IDENTICAL stars (same absolute magnitude) and see if/how distance affects the "apparent magnitude" of stars.

3. Sketch a model of our investigation & take notes on our conclusion/findings... the CLOSER a star is to Earth the BRIGHTER it will appear, which is why our SUN looks SO BRIGHT, since it is the only star within our solar system, so it is the closest to us. 

4. Discuss the DIFFERENCES students had researched about stars from last week... size, temperature, color and age were all characteristics identified by the class...

5. Video to show how much the SIZE differs amongst stars....

6. Slideshow to show how small we truly are...

NO Assignment

Thursday

QUESTION:

What causes some STARS to BE BRIGHTER?

What causes some STARS to APPEAR BRIGHTER (even if they are not actually as bright) as another?

Finished Slideshow from yesterday...

1. Opener: What do you notice/wonder about FIRE??? Video of a campfire - how is a FIRE similar to stars?  

2. Take notes on the Hertzsprung-Russell Diagram (a diagram that classifies stars based on their temperature/brightness)... we Colored the 4 columns... we labeled the axes....and talked about how stars are placed on the diagram...When, we identified WHERE our sun falls within the diagram - ****copy notes from a friend... we still have to finish this next week Tuesday, so you can get caught up Tuesday on this

Friday

NO CLASS DUE TO SCHOOL PEP RALLY

Planning Ahead:

Several writing assignments in the coming weeks.

No major tests/projects this week
