Name ___________________________________________ Date ________________ Period __________
Directions: This test is designed to let your teacher know how much information you have learned
over the past few weeks, and to allow you to gauge this as well. Remember to think about your notes, and
all the examples and demonstrations that we’ve done in class. Read each question carefully and completely
before making your response, and make sure that whatever you write answers every part of the question. Do
not leave any blank questions or naked numbers. Relax, good luck, and enjoy!

5. With what other atoms might hydrogen form a hydrogen bond?
6. If Sir Henry Florence-St. Claire’s microscope has an eyepiece with 10x magnification, and a high power
objective of 43x, what is the total magnification of his ‘scope under high power? Show how you got your
answer in the space below.
7. An ionic bond is the strongest chemical bond. What does it involve?
A. Sharing electrons between three atoms to increase the strength.
B. Swapping electrons with other atoms
C. Completely transferring electrons from one atom to another.
D. Moving protons to create a positive charge.
_________
8. Boron is element number five on the periodic table, so it’s atomic number is five. How many protons
does boron have?
9. How many electrons does boron have in its first shell? How many does it have in its second?
10. How many more electrons does boron need to have a full valence shell of electrons?
For questions 11 through 16, place a check under “GS” if the item is good science, and put one under “BS”
if the item is bad science.

_________
_________
27. Describe how a polymer can be formed from monomers. You may write, draw, or both.
28. Sally measured the pH of the water from her faucet, and finds that it is 3. Why should this worry her?
29. Sally brings a small sample of the water into her bio class for some tests. What could her teacher add to
the water to make sure that the pH of the sample does not change during the tests?
30. In plants, monosaccharides are least likely to be

_________
31. In the space below, using one or more complete and well-structured paragraphs, explain why oil and
water will not readily combine. Also explain why the addition of a detergent such as soap will allow the two
to mix. Because you know that cell membranes are made out of lipids and are surrounded by water, make a
hypothesis about what would happen if soap was added to a cell membrane. You may wish to include some
of the following terms in your response:
Polar
Amphipathic
Non-polar
Soap
