Question

I have a couple of science questions I would like someone to double check for me. Please & thank you in advance :)

1. Sandy was given the following series of observations. Which represents a theory?

A.) Light from the sun is warm.
B.) Light from the sun is bright.
C.) The sun formed from the compression of a cloud of gas and space dust. (I think its this one)
D.) The sun appears orange-yellow in the morning and red-orange in the evening.

Answer 1

2. When a scientific investigation produces evidence that does not support the hypothesis, what can you conclude about the investigation?

A.) A law has been formed.
B.) A theory remains accurate.
C.) A theory has been disproved.
D.) More investigations need to be completed. (I think its this one.)

Answer 2

3. When a local farmer found oil bubbling to the surface in one of his fields, he reported the information to a group of scientists. After 30 years of experimentation, the scientists develop a new theory about how oil formed beneath this location. How do you know that this information is really a theory?

A.) The theory proves a scientific law.
B.) Most of the data were unobservable.
C.) The theory was developed over time.
D.) The data describe a natural phenomenon.

Kinda unsure of this one. Is it B or C?

Answer 3

You are right on the first one

Answer 4

C. the theory goes that ...the sun formed ... (no direct proof, since I wasn't around at the time and had I been, I'd probably have been killed in the "solar storm" etc).

Answer 5

What about the other two, are they correct?

Answer 6

@osprey

Answer 7

Did you still need help with this?

Answer 8

I agree with 1C and 2D

Answer 9

As for the last one, I think it could be either A or D

Answer 10

Conjecture could be developed over time, anything else can. Just because it took to infer, it doesn't validate it as a theory.

Answer 11

As for the data not being observable, it says first the scientists were sent data, then they did experimentation. We can't measure what data, and how much was given to the scientists, or what was available overall, so B seems incorrect

Answer 12

Scientific law is defined as - "a statement based on repeated experimental observations that describes some aspects of the universe." This theory as said by the question, is "about how oil formed beneath this location."

Answer 13

So A seems a good candidate, then there is D.

A "scientific" theory is defined as - valid explanation of a phenomenon

Answer 14

Leading towards D, as...

" he reported the information to a group of scientists. After 30 years of experimentation, the scientists develop a new theory about how oil formed beneath this location."

A 'scientific' theory is defined as - valid explanation of a phenomenon

D.) The data describe a natural phenomenon.

Data, or information, is what makes a theory

Answer 15

Not to say that a theory consists of data, but that information makes or breaks a theory. Theories start from scientists viewing data, forming a hypothesis, then experimenting with that data, get evidence, then bam, theory

Answer 16

If evidence is found that contradicts a theory, it can be proved invalid

Answer 17

No idea if you're here or not, lol. The questions looked interesting and I didn't mind doing some research. Hope this helped in some way.

Answer 18

first one is observation = summer ? so it's not per se a theory.
next one is observation = sunglasses
last one is observation = eyesight/spectrometer.
A theory WOULD TRY to EXPLAIN the observations ...

Answer 19

the modernish day classic theory so far is that of Albert and Mileva-Maric Einstein. AKA special relativity and AE's general rel they are ideas about ways in which certain baffling things to Nobel prize winning physicists can be explained. Professor Frau Lisa Meitner used Einstein's theory to realise that she and her colleagues had fissioned/split the nucleus of an atom

Answer 20

What do you think the answer is?

Answer 21

just seen the other q.
obs is the crude "black gold" "texas tea" oil bubbling up.
q now is "any ideas how it got there ?"
the geophysicists, presumably, did further "tests" and constructed a geo physics model of what they thought was happening, and thus a theory.
although geological oil doesn't bubble up anywhere near me, I'm lead to understand that it's still a "natural phenomenon". Much like hurricanes, few if any of which i've actually experienced.
So, i guess that the "bottom line" of the above verbiage is to wonder which one I'd actually go for.
Sorry about this.

Answer 22

@ShadowLegendX @osprey Thank you guys so much. D wasn't the right answer for the last question so it must've been C? BUT i still got a 98% so I cant complain :)

Answer 23

Last one was more difficult and required more in-depth knowledge, but glad we were able to successfully help you with the others

Answer 24

good ppl

Answer 25

a 98%
That's a good score .... I'm smiling
