Environmental Challenge!

1/27/2017

For the past three days my class and I have been doing the Environmental Challenge where we try to solve Environmental problems. That is were we think up ideas of ideas that can solve problems. We made things and had some supplies but first we had to make a drawing. Next we got to build the idea or gadget.

I decided to stop air pollution/Depleting atmosphere, it was a wind powered car that doesn't give of a ton of CO2 in the air. It will help global warming to. It will also conserve gas because it runs on air.

My solution is to make a car that helps lots of problems. It can stop the atmosphere depleting because there is no CO2 in the air, that also means it stops global warming which is when the atmosphere is depleted it lets more sun in which creates more heat. It also conserves resources by not depleting gas or using electricity.

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?

The difficult part was making the idea. You had to think creatively.
I learned how to think outside the box. I also learned about some of the main problems on Earth.
The advice I would give is to set mini deadlines within the time frame. It allows you enough time to get stuff done but not so much that your wasting time.

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?

The Sun went the same arc every day because it is a pattern, but it moves a little higher or lower every day. But it looks the same.
The height of the Sun got higher until noon, then got lower because the Sun finished it's arc for the day. The sun moves down because the Earth is spinning.
It was important to use the same landmarks so that the shadow is accurate and it is the same angle each day. The permanent makes it accurate and more precise.
The sun got higher than lower throughout the day. It was higher at noon and lower in the morning and the afternoon.
Almost the same because it is moving up on the arc. It would be almost the same but a little different because the sun moves changes the angle every day because the Earth is always moving.
You would notice a difference because the Sun changed on the angle of the earth.
The sun would look the same because it follows a pattern. That means it follows a 6 month pattern.
I think the sun doesn't move around the earth. I think we are moving not the sun.

Will the height make a difference?
Hypothesis. Higher = Deeper crater.
Answer It didn't make a big difference.

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?

Remember that some questions need at least two sentences!

.The best shape is a sphere so it can rotate and you can't fall of the earth.
Earths gravity pulls things to the center.
.Tennis Ball and Rubber Band because it shows you you can't fall of the earth.
.It is helpful because you can look at it and not have to just imagine what it looks like.
.Yes, Because it orbits so that means it is still affected.
.It stays up because the plane has an engine and a bird has wings that let it glide and it flaps it's wings to generate force to lift it up.
.No, or atleast not until you leave the earth or the solar system.
.Gravity affects the meteorite which changes the crater

I was not here

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!)

The scale of a drawing represents a smaller version of an object. 5
My model of the Earth is 1 quintillionth. (just a guess)
The drawings accurately represent Earth because it is mostly water. It is also the same, because Earth is at a 23 degree angle.
Earth looks different from our perspective and from space's perspective. The Earth looks round from space and flat from our perspective.
