Answer the following on lined paper…
Which mystery disk inference or prediction are you the most certain about? Are you 100% certain or just almost certain? Explain why.
Which mystery disk inference or prediction are you the least certain about? Are you 0% uncertain or just a little uncertain? Explain why.

Do NOT change yours!

6. Training in the Art of Hearing, in order to Predict or infer
A smooth rolling sound likely means it is traveling on the side of the disk.
A tap sound likely means it has hit a wall.
A slide likely means it is on a flat surface.
A drop means it has fallen from one place to another.
Your objective is to make a prediction or inference about the layout of the walls inside the disks without looking!

15. How do scientists explore inside Earth?
Reading Strategies
Reason for reading:
How do scientists explore inside Earth?
Before:
Skim.
Look at headings.
Ask questions.
During:
Highlight, circle, mark-up, annotate, underline.
Pictures in your head.
After:
Summary in LNB. A few (four or five?) sentences.
Did you answer your questions?
What did you find out about the reason for reading?

18. Comparing Predicting the Mystery Disk to Predicting the Inside of Earth.
Come up with at least 5 ways that exploring the disks is similar to exploring the inside of the Earth.
Come up with at least 5 ways that exploring the disks is different from exploring the inside of the Earth.
Quote the reading if you can! (Line number)
“The surface of Earth is constantly changing” (line 2) while the surface of the unknown disks stay the same.
Write in full sentences.
Might be collecting in. If not today then… soon!

21. The disks don’t have Earthquakes and Seismic waves.
Earthquakes are similar to shaking the disk.
Sesimic waves are similar to sound waves.
You listening is like the ‘fancy tools’ scientists use to measure the seismic waves. Seismographs.
At first we didn’t know what was inside the disk, just like we have a minimal understanding of the inside of Earth.
Earth gives clues to geologists about the structure, the disk gives clues about the layout.
Scientists infer Earth’s inner structure by recording and studying. We also infer about the inside of the disk by infering and studying.
Both the Earth and the disk rely on methods of indirict observation?
We couldn’t open up either or look inside.
We can take samples from the Earth but we can’t take samples from the disk (Line 28)
Eventually we got the answers for the disk but we are never going to get the answers handed to us for the Earth.
The Earth is constantly changing while the disks stay the same (line 2).
The disks don’t have Earthquakes and Seismic waves.
The Earth is millions of years old while the disks are a few years old (at least 6)!
You have to travel over 6,000 km to get to Earth’s center but you don’t have to travel for the disks.
The Earth is spherical and the disk is flat.
Geologists use their fancy tools to found out what is inside the Earth. We used our ears.

22. Both Earth and disks have solid, metal spheres.
You can’t open up either.
You can’t get into the Earth because of the extreme conditions. Disks (tape).
We can assume/predict/infer what is inside based on on observations.
There are negative consequences to opening to either (assuming you could)
You can’t see into either.
You can only use indirect evidence?
You can poke a hole in either.
There is less inside the disk than there is inside the Earth (Earth more complex).
You can tilt the disk but not the Earth.
The surface of the Earth is constantly change but the disk really doesn’t much.
The disks are hollow but the Earth isn’t.
The metal sphere inside the Earth does not roll around... or does it?
The disks don’t have rocks but the Earth does.

23. …You can break and bend the disk (you just aren’t allowed to) and the Earth breaks and bends.
Human’s try and find what is inside both.
Scientists use common sense to figure out the inside of both.
You can’t see what’s inside the disk and you can’t see what’s inside the Earth.
Both were unknown (at one point).
Both have a circle shape in some form or fashion (disk vs. sphere)
You’re able to figure out what’s inside of both with observations from the outside (hopefully)
We can collect data for both (studying the Earth and the disk)
…You don’t shake and turn the Earth but you do shake and turn the disks.
The disks are smaller than us and the Earth is much bigger.
The disk is plastic and the Earth is made of ?.
While there are sometimes volcanoes on Earth that gives us samples but we get no samples from the disk.
Earth’s surface is constantly changing while the disk’s surface doesn’t.
Geologists have drilled holes into the Earth (12 km) but we weren’t allowed to drill into disk.

24. Earth gives clues to geologists about the structure, the disk gives clues about the layout.
Earthquakes on the surface of Earth are similar to us shaking the disk.
Sesimic waves that travel through Earth are similar to sound waves traveling to our ear.
Us listening with our ear is like scientists using ‘fancy tools’ scientists use to measure the seismic waves (seisomgraphs)
Scientists infer Earth’s inner structure by recording and studying. We also infer about the inside of the disk by infering and studying.
We can take samples from the Earth but we can’t take samples from the disk (Line 28)
Eventually we got the answers for the disk but we are never going to get the answers handed to us for the Earth.
The Earth is constantly changing while the disks stay the same (line 2).
The Earth is millions (billions?) of years old while the disks are a few years old (at least 6)!
Geologists use their fancy tools to found out what is inside the Earth. We used our ears and hands.
Geologists have drilled holes into the Earth (12 km) but we weren’t allowed to drill into disk.

25. …You can break and bend the disk (you just aren’t allowed to) and the Earth breaks and bends.
Human’s try and find what is inside both.
Both Geologists rely on indirect observations?
Scientists use common sense to figure out the inside of both.
…You don’t shake and turn the Earth but you do shake and turn the disks.
The disks are smaller than us and the Earth is much bigger.
The disk is plastic and the Earth is made of ?.
While there are sometimes volacnoes on Earth that gives us samples but we get no samples from the disk.
Earth’s surface is constantly changing while the disk’s surface doesn’t.
Geologists have drilled holes into the Earth (12 km) but we weren’t allowed to drill into disk.

26. Statements to discuss
They both (Earth and disks) use indirect observations.
The disk doesn’t have Earthquakes or seismic waves.
