Mastery Quest- Eclipses, Seasons & Tides

Question 7:  The Earth is tilted __ degrees.

Right Answer: 23.5

Explanation: 23.5 is the correct answer because the Earth's axis is tilted at 23.5 degrees.


Question 15: What type of tide would this arrangement of earth-moon-sun create?

Right Answer: Spring tide

Explanation: The correct answer is spring tide because when the Moon, Sun, and Earth are in line the Sun and Moons gravitational pulls work together to create spring tides. (Spring tides have really high high tides and really low low tides).


Question 17: Why do we experience the changing of the season on the earth?

Right Answer: the tilt of the Earth's axis

Explanation: The correct answer is the tilt of the Earth's axis because as the Earth revolves around the Sun, the tilt of the axis affects the position of the Earth in relation to the Sun which causes a change in seasons throughout the year. 


Question 21: Which solar system event can only occur during a full moon phase?

Right Answer: lunar eclipse

Explanation: A lunar eclipse is the correct answer because a lunar eclipse occurs when a full moon is in the umbra, a location shadowed by the Earth.


Question 33: What causes the angle of the sun’s rays to change during the year on Earth?

Right Answer: the tilt of the Earth's axis

Explanation: The correct answer is the tilt of the Earth's axis because, without the tilt of the axis, the hemispheres wouldn't lean towards or away from the Sun. This means that different parts f the Earth wouldn't receive different amounts of sunlight. Also, when at angles, places absorb different amounts of sunlight.


Question 36: There are places in the world that experience 24 hours of day of daylight. Where do you expect this to happen?

Right Answer: the poles

Explanation: The correct answer is the poles because those are the places on Earth that roughly remain in the same general area when the Earth rotates.

Cladograms, cladograms, cladograms 10/22/17

Image: Pierre Kleinhouse Summary:  When we think of evolution we see monkeys magically turning into humans, but what is missing from that picture is the portion below it that makes it a cladogram. What is a cladogram? A cladogram is a diagram that shows the common characteristics of certain animals, as well as how closely related they may be. The top of the cladogram includes the organisms name and sometimes a picture. On the side of the cladogram, you will usually see different characteristics. Since a cladogram is drawn at a downward angle, the characteristic applies to everything above that point on the diagram. As you go up the cladogram, the animal at the top has all the characteristics listed throughout the cladogram. Along with this, the points in which two animals meet is not when they evolved from one another, but their common ancestor. Lastly, the diagonal line of a cladogram represents time.

Image: www.flickr.com Summary: Throughout this week, the main topic of discussion was food waste and food systems. To understand the food system and how it works, we went through the system of apples and how they can be wasted in each step. The apples are produced and they can be wasted when they are eaten by insects. Due to this, they can't sell, so the farmers throw the apples away. Next, the apples are harvested. If apples have fallen on the ground or are not up to standard the farmers throw them away, even though they are perfectly fine. After that, the apples are washed and waxed to look appealing to customers. During this step, apples are wasted if the they are ruined while waxing. Some apples are then processed into different food items, such as pie filling, apple sauce and more. If people mess up during this conversion, the apple product gets thrown away. Then, the apples are packaged.If packaged incorrectly, the apples get thrown away. After this step, the apples ge...
