Week 6 Science Methods

 What did you do in lab today?

1. How the phases of the moon occur?

I am not extremely knowledgeable about the phases of the moon other than knowing that there are phases and that in the different phases the moon looks different because parts of it are shaded.

2. What causes the seasons?

From my understanding, the different seasons are because of where the Earth is at in location to the sun and how the Earth is tilted.

3. What causes a lunar eclipse?

A lunar eclipse is when the moon is perfectly in the Earth’s shadow so the moon is hidden/you can’t see it. 

What was the big question?

Geocentric: that the earth was in the center and that everything went around it. 

Heliocentric: how the sun is in the middle and everything goes around the sun. 

Copernicus: wrote a book about the sun being in the middle.

Galileo: thrown in prison for believing that the sun was in the middle.

Plane of the Ecliptic: all of the planets are on the same plane.

Equinox: fall- September- 12 hours of daylight, 12 hours of darkness for every place on the planet (2 a year)

Solstice: spring-march ^ 

Equator and the tropic lines: winter- tilted away from the sun.

Tropic of Capricorn: southern hemisphere that has the most sunlight around December 21st. 

Tropic of Cancer: 6 months later the sunlight hits the Tropic of Cancer the most 

New moon: when the moon is being reflected away from the earth, so we don’t get as much sunlight from the moon.

Full moon: all of the light is reflecting it back onto the earth from the moon.

Red mooon: when the sun is set at night, the moon is in the east, the sunlight is going through the atmosphere, the red light wave becomes dominant. 

If the sun is rising in the eat at 7 am while the moon is setting in the west, what phase of the moon is it and how do you know? Full moon or a lunar eclipse

New moon can only give a solar eclipse- not a lunar eclipse

What did you learn in Thursday’s discussion?

Some things I learned in Thursday’s lecture:

- the moon’s phases have nothing to do with the calendar. 

- Perihelion: when the Earth is closest to the sun ~ January 4

- Aphelion: When the Earth is farthest from the sun ~ July 5 

Read the online textbook, chapter 5: https://pressbooks.uiowa.edu/methodsii/chapter/earth/

What did you learn?

Heliocentrism: the fact that the sun is in the center

Geocentrism: theory that the Earth is in the center of the solar system.

Phases of the moon:

• New: The Moon’s face is not visible from Earth
• Crescent: Between a new moon and a quarter moon
• Quarter: From Earth, we can see half of the moon’s face which is a quarter of the entire moon
• Gibbous: Between a quarter moon and a full moon
• Full: All of the Moon’s face is visible from Earth

What was most helpful?

The moon phases image was really helpful in putting the moon’s phases into perspective.

Also I didn’t realize that equinox and solstice both happen twice a year, so that was helpful to learn/realize. 

What do you need more information on?

I still feel like I need more information about the equinox and solstice.

What questions, concerns, and/or comments do you have?

None right now
