Here are links to materials for particular
labs:
- Lab 1: handout "The Scientific Method"
(the Daphnia lab)
- (Lab manual chapter 1 "Experimental Design"
- use for another presentation of basically the same material)
- Here are some alternate
definitions/explanations for the terms in this lab:
- Dependent Variable - this is what is
being measured or counted in the experiment; the "results" or raw data.
It changes in response to the experimental conditions - the dependent variable
is dependent on the independent variable.
- Independent Variable - this is the one
variable that is changed or manipulated to test the hypothesis. The
experiment is designed to test whether or not the independent variable has an
impact on the dependent variable.
- Controlled Variables - these variables
are kept constant in all of the experimental samples. Basically, all of
the experimental samples are exactly the same except for the
presence/absence/amount of the independent variable. The controlled
variables (or "constants") include EVERYTHING that can be controlled in the
experiment, except for the independent variable.
- Experimental Treatment - the treatment
using the independent variable.
- Control Treatment - the treatment
without the independent variable. You want to know what happens without
the independent variable, so you know that if the independent variable has an
impact on the dependent variables in the experiment, that it was because of
the independent variable and not something else. (This is also why the
independent variable is the only variable that is different from one sample to
the next, and this is why the controlled variables/constants are constant in
ALL samples.)
- Lab 2: Lab manual chapter 14 "Animal
Diversity"
- Lab day 1: movie "Microcosmos"
[Microcosmos:
Le peuple de l'herbe (1996)]
- This video is
available for checking out through the Hennepin
County Library System.
- You will be expected to know the
items on the handouts that go along with this movie on any tests or quizzes.
- Lab day 2: observe animals on display
- Lab 3: Lab manual chapter 13 "Plant
Diversity"
- Lab 4: Lab manual chapter 2
"Biochemistry"
- These links have some material you might find
useful (keep in mind they are sites made for other classes at other schools,
so just use the parts that are relevant to what we did in lab):
- Lab 5: Lab manual chapter 3 "Cells"
- Links to different microscope sites that might
help (careful, though, they aren't all exactly the same as the microscopes we
used in lab).
- This
Santa
Monica College site has a bunch of text at the beginning, but if you
scroll down to the microscope diagram, it's pretty close to one of the ones we
used in lab. A little further down the page are some more good diagrams
and explanations.
- The labeled microscope diagram on this
Edwards-Knox
Central School site is different from the Santa Monica College diagram,
but it also has some good diagrams and explanations (including calculating
magnification and estimating size of specimens).
- Links to pictures of organisms observed in lab
(I am only endorsing the pictures - I haven't had time
to look carefully at these web sites, so I haven't double-checked the facts on
these pages, nor do I endorse any activities that may be found on these pages.)
-
Paramecium:
Paramecium caudatum,
Paramecium,
Paramecium,
Paramecium (has some links that might be interesting
for extra info),
Paramecium
(has some links that might be interesting for extra
pictures of other things, like bacteria),
Paramecium
(with taxonomic classification)
- Saccharomyces cerevisiae:
this is what they look like in lab,
scanning electron
microscope pictures,
yeast and
fermentation,
false color,
Bread
Science 101,
brewing web site,
-
Elodea
- flower petal chromoplasts:
in fruit, , (chromoplasts
and flower color)
-
(Homo sapiens)
human epithelial
cells;
here's another
one (not great, but you should get the general idea)
- bacteria:
gram
stain of E. coli,
E. coli
electron micrographs,
links to various
bacteria, this one
has some interesting extra stuff about classification of bacteria
- This is a link to some
sample math questions
that you might find useful (should help you with calculating magnifications,
sizes, etc.). Here are the answers (I'll activate this link in a
day or two).
- We didn't look at these in lab, and
you don't need to know them for the lab exam, but I thought you might find
them interesting anyways.
(I am only endorsing the pictures - I haven't had time
to look carefully at these web sites, so I haven't double-checked the facts on
these pages.)
Lab Exam 1: covers labs 1-5 (chapters 1,
14, 13, 2, and 3)
- Lab 6: Lab manual chapter 4 "Osmosis and
Diffusion"
- Here is a link to some
sample questions
you might find helpful for this topic. Here's a link to the
answers.
- You should be able to answer these questions in
the lab manual: 1-13 (pages 53-56).
- Lab 7: Lab manual chapter 6
"Respiration" (see the general links on
my NHCC Home Page)
- You should be able to answer these questions in
the lab manual: 1-6 (pages 81-82), and 18-21 (page 84).
- Lab 8: Lab manual chapter 7 "Photosynthesis"
(see the general links on my NHCC Home Page)
- You should be able to answer these questions in
the lab manual: 1-6 (pages 95-96), 27-29 (page 101), and 33-36 (page
102).
- Lab 9: Lab manual chapter 8 "Mitosis and
Meiosis" (see the general links on my NHCC Home
Page)
- You should be able to answer these questions in
the lab manual: 1-21 (pages 113-118; just change "leek" to "onion" in
questions 3 & 4).
- Lab 9: Lab manual chapter 10 "DNA"
for the DNA extraction exercise (except we used wheat germ instead of onion;
"DNA spooling")
- You should be able to answer these questions in
the lab manual: 14-16 (page 143).
