Observing the Sun for a Day

1/30/2017

Reflection/Synthesis Questions:

What shape (or pattern) did the sun appear to make in the sky over the course of the day? What evidence do you have to support your explanation?
How did the height of the sun change during the day? What evidence do you have to support your explanation?
Why was it important to use the same landmark(s) for each observation and have a permanent spot to record our observations from?
When you look at your data from the day, how did the sun’s position seem to change over time?
If you did the same activity next week, do you think you would see the same pattern of movement of the sun? Why or why not?
What about next month?
What about 6 months from now?
Based on your observations, where do you think the sun goes every evening?

Reflection Answers:

The sun appears to travel in arcs because the earth spins.
The height changes because of the arc it travels in.
It was important because otherwise the sun would move to much or not enough.
It seemed to start long then get short and long again.
It would still travel in an arc but the length would be shorter because the "height" of the sun changes with the seasons.
It would get even shorter because the "height" of the sun changes with the seasons.
It would be much shorter because the "height" of the sun changes with the seasons.
The sun does not move but it appears to move because of the earths spin and tilt.

In this challenge we had to choose an environmental problem and make an attempt to solve it. After that we had the choice to enter it into a contest. The problem that I attempted to stop was air pollution, I attempted to solve it by making a item to but on the exhaust pipe of a car that filters the air.

Reflection/Synthesis Questions:

What was difficult about this challenge?
What did you learn while completing this challenge?
What advice can you give others about becoming better at time management?

Reflection Answers:

The hardest part of this challenge was probably deciding what environmental challenge to solve.
I learned that their are a lot more environmental problems than you would think.
I learned that if you have a lot of things to do make a schedule with priorities first.

Observing Shadow Patterns

Weather didn't permit.

Reflection/Synthesis Questions:

How are shadows made outside in the daytime? Provide some evidence to support your answer.
Can shadows be made inside the classroom? If so, how?
Do outside shadows change during the day? If so, how? Refer to the pole or stick the class observed outside if needed.
Think about the time between observations of the pole’s shadow. What happened?
What does this (the answer to #4) tell you about the sun’s position in the sky?

Answers:

Their are shadows on the ground because all objects block the sun's rays from hitting the ground.
Shadows can be made inside classrooms by blocking the light of the lamps.
Yes, they change when then sun "moves" throughout the sky by always staying in the exact opposite position.
The shadow got shorter until midday and then started to get longer.
It tells me that the higher the sun is in the sky the shorter our shadows will be.

Questions:

Will the height make a difference?

Hypothesis:

Yes because things gain velocity when they fall.

Answers:

No it somehow didn't make a difference

Reflection/Synthesis Questions:

Which of the following best describes Earth’s shape?
A. disk
B. circle
C. sphere
D. plane
Earth’s gravity pulls an object toward its ____________________.
Which model do you find most useful to explain gravity and its effects? Why?
- Tennis ball and rubber band?
- Styrofoam ball and toothpicks?
- Circle on paper with arrows?
Why are models helpful at explaining complex scientific concepts like gravity?
Do you think the moon is affected by Earth’s gravity? If so, why doesn’t it fall “down” toward the Earth?
Why doesn’t a plane or bird fall from the sky?
Does gravity ever stop working? Do any forces ever cancel out gravity or reverse it? Explain.
Why is this lesson on gravity a good time to teach about craters?

Answers:

C.
Core.
Circle on paper with arrows, because it shows that any where you are gravity always pulls downward.
Because it makes it easier for people to grasp a concept.
It is affected by earth's gravity but, is big enough to resist it somewhat.
It doesn't fall from the sky because has enough momentum and force to stay off the ground.
No, gravity never stops working but, if something has enough mass it can cancel it out.
It is a good lesson because craters are caused by meteors which are highly affected by gravity.

Day and Night Notes:

Day and night are caused by the spinning of earth.

Notes from my research:

All the other planets are round so there is no reason earth woudn't be.
If you tried to walk in a square with sides all of 10 km you'll be back were you started on the third angle.
The stars change if you go north or south.
You can see the sunset twice if you lay down and then stand up.

Notes from the videos:

You can see the earths round shadow on the moon during a lunar eclipse.
Things look like they sink if you are far enough away because of earth's curve.
If you wiegh the same everywhere your planet is round.
We can now travel to space and take photos and videos that show earth is round.

Reflection/Synthesis Questions:

What does the scale of a drawing mean?
How does the size of their drawings of Earth compare with the actual size of Earth?
Even though your drawings are different than the actual Earth, in what ways do they accurately represent Earth?
How does the point of view of a drawing affect the way objects look?

Answers: (Remember to have at least two sentences for each answer whenever possible!)

It means that the earth is round and is supposed to be large.
It compares by the continents being much bigger than usual.
It accurately shows that earth bulges a little in the sides because of its rotation.
If you drew it from your point of view it would be very different than an astronaut's point of view.
