The Nature of Science & the Origin of the Ocean (Topic 2B)
1. Is the following statement an example of a scientific observation?
Why or why not? (Choose the “best” answer.)
“A penny sinks in water because a penny has a density that is higher than the density of water.”
● yes, because it is an educated guess
● yes, because it is the commonly understood scientific explanation
● yes, because you can observe whether or not a penny sinks in water
● no, because an observation is something that you see, hear, etc.
● no, because there are other possible reasons that an object might sink (e.g., lack of surface tension)
● no, because you cannot see the density of an object
2. Which of the following are observations? (Circle all that apply.)
● “I heard her say that she was going to the mall.”
● “He has a lot of dandruff in his hair.”
● “This cake tastes like strawberries.”
● “Telling someone a lie is always wrong.”
● “I prefer green tea to coffee.”
● “Yesterday morning I drank a lot of coffee and later in the day I felt pain in my stomach.”
3. Why is observational evidence the only kind of evidence that can be used in science to support
an idea about the world? (Choose the “best” answer to this question.)
● because it is used as evidence in a court of law (e.g., a jury trial)
● because every time that you do an experiment, the observations are the same
● because scientists do not believe in the existence of things that they cannot see
● because you can always “check” whether or not what other people tell you is true
4. What word do scientists use to indicate
that an idea is an “educated guess?”
____________________________________
5. Is the following statement a scientific hypothesis? Why or why not?
“Häagen-Dazs makes the best ice cream.”
Yes, it is a scientific hypothesis, because:
● the idea can be tested
● the idea is an educated guess
● the idea is true
● there is a lot of evidence supporting the idea
No, it is not a scientific hypothesis, because:
● the idea cannot be tested
● the idea is wrong
● there is little (or no) evidence supporting the idea
● this is a statement, and hypotheses are questions
Practice Exam #2 (Topics 2B, 3A, & 4A) – page 3
6. Can a theory change? Why or why not?
7. If a science textbook uses the word “theory” to describe an idea, does that mean that scientists are
confident that the idea is correct or does it mean that they are not very confident that the idea is correct?
Why are they confident or not very confident that the idea is correct?
8. Identify which element of the scientific method each of the following statements represents.
In other words, which ones are hypotheses? Which ones are tests? Which ones are observations?
The egg floated is salty water, but not in fresh water.
Life began on land, not in the ocean.
A scientist weighed a container full of a liquid a scale and looked at
the markings on the side of a beaker to determine the volume of the
liquid.
Students placed 4 pennies into a small film canister and placed it into
water to see if it would float.
There is more life near the coast, because the concentration of
nutrients is higher in coastal water.
The waves in the harbor were smaller than the waves breaking on the
sandy beach along the open coast.
Practice Exam #2 (Topics 2B, 3A, & 4A) – page 4
9. Consider the following two ideas. Is either one scientific hypothesis?
In other words, can its “correctness” be tested by gathering observational evidence?
Idea #1: “Baby dolphins swim next to their mothers, because it helps them swim faster and keep up.”
Idea #2: “Killing dolphins is wrong. It should be illegal to kill dolphins.”
If you answered “yes,” how could you test this idea? In other words, how could you gather observational
evidence that would allow you to determine if the idea is true or not?
If you answered “no,” why can’t this idea be tested? To answer this question, give an example of
observational evidence that you could gather to try to test this idea, and explain why this evidence would
not be sufficient for conclusively determining whether the idea is true or not.

bonds formed by alcohol molecules? Explain your reasoning.
In a drop of water, the molecules of the liquid are constantly resisting
the force of (A)______________________ which is trying to pull them downwards and apart.

The drop of (B)____________________ spread out more than the drop of (B)____________________.
The molecules of (B) ____________________ were better able to remain together
than molecules of (B) ____________________,
because the (C)____________________ bonds that exist between them are harder to “break.”
Possible Answers:
A: give the name of the force
B: alcohol, water

45. Consider the experiment in which we observed how liquids like alcohol and water naturally climb up

bonds formed by alcohol molecules? Explain your reasoning.
We can see that the molecules of liquids in the thin tubes were attracted to
the molecules of the (A)_____________________,
because the liquids rose upwards against the force of (B)___________________________.
Since the molecules of (C)_________________________ were better able to overcome this force
and rose up higher than the molecules of (C)_________________________,
molecules of water must form (D)___________________________ bonds than molecules of alcohol.

A: air, tube
B: give the name of the force
C: alcohol, water
D: stronger, weaker

46. Is water an excellent solvent or a poor solvent?
Can water dissolve all substances?
Excellent / Poor
Water dissolves All / Most / Few Substances
47. Which bonds are stronger, the bonds between salt atoms or the bonds formed by water molecules?
How is water able to dissolve salt?
● bonds formed between salt atoms:
water molecules’ sharp, triangular shape helps them separate salt atoms
● bonds formed between salt atoms:
only a group of water molecules pulling together are strong enough to pull salt atoms apart
● bonds formed between water molecules:
water molecules have very strong bonds that can easily pull salt atoms apart
● bonds formed between water molecules:
because water molecules are dipolar, so both positive and negative salt atoms are attracted to them
48. Why is fresh water able to dissolve more salt than salt water?
● fresh-water molecules are dipolar
● fresh-water molecules can form more bonds in more directions than salt-water molecules
● fresh-water molecules form stronger bonds than salt-water molecules
● in fresh water, there are more water molecules which have not bonded with salt atoms (yet)
● in fresh water, there are many more water molecules (10 times more) than in salty water
● in fresh water, there is more room for atoms and molecules to move around
● in fresh water, it is easier for a group of water molecules to surround salt atoms (less salt in the way)
49. Which dissolves more salt, alcohol or fresh water? (Lab)
Why is one able to dissolve more salt?
● Alcohol: alcohol molecules can form more bonds in more directions than water molecules
● Alcohol: alcohol molecules form stronger bonds than water molecules
● Alcohol: alcohol molecules are smaller, allowing more of them to surround and pull on the salt atoms
● Water: water molecules can form more bonds in more directions than alcohol molecules
● Water: water molecules form stronger bonds than alcohol molecules
● Water: water molecules’ sharp, triangular shape helps them separate salt atoms
50. Do salts and nutrients dissolved in ocean water slowly sink towards the bottom of the ocean? (Class)
Why or why not?
● sink: the surface area of salt atoms and nutrient molecules is too large
● sink: salt atoms and nutrient molecules More / Less dense that water molecules
● do not sink: salt atoms and nutrient molecules are bonded to the water molecules
● do not sink: salt atoms and nutrient molecules are More / Less dense than water molecules
