Learning through Art: Nutrient Cycling and Energy Flow in Ecosystems
Can you label this diagram showing how nutrients and energy flow in an ecosystem?

inquiry
Using a type of logic known as ___ , a generalized conclusion can often be drawn from a large number of

A(n) ___ is a proposed explanation for a set of observations. It leads to predictions that can be tested by
additional observations or by experiments. - hypothesis
___ uses ''if . . . then'' logic to proceed from a general hypothesis to specific predictions of results that
can be expected if the general premise is true. - Deductive reasoning
A hypothesis must be testable and ___ --there must be some observation or experiment that could
show that it is not true. - falsifiable
A(n) ___ involves both an experimental group and a control group, which are alike except for the one
variable that the experiment is designed to test. - controlled experiment

Scientific Thinking: What Role Does Peer Review Play in the Process of Science?
Imagine that you are a scientist hard at work in a cancer research lab. You and many of your colleagues
are hoping to discover new powerful drugs that could prevent deaths from cancer.
Your research team has observed that cancer cells have a lower survival rate when exposed to samples
of a certain species of fungus. To study this further, your team isolated several chemicals from the
fungus, including one known to affect cell metabolism. You hypothesize that it is that chemical that
lowers the survival rate of cancer cells.
Part A - Interpreting graphs
, Based on your hypothesis, you predict that the chemical isolated from the fungus will successfully kill
cancer cells. To test this prediction, you design the following experiment.
You isolate cancerous cells from the colon of a patient from North Carolina and culture (grow) the cells -
Statement(s) supported by the data:
--------------------------
1) Cancer cells treated with the chemical have a lower survival rate than cells that are not treated.
2) After 5 days of chemical treatment, less than 50% of the cancer cells are alive.
Statement(s) NOT supported by the data:
--------------------------
1) Cancer cells treated with the chemical have a higher survival rate than cells that are not treated.
2) This chemical will be useful for treating all types of cancers.
3) This chemical will be useful for treating colon cancer, but not necessarily for other types of cancers.
4) After 10 days without chemical treatment, more than 90% of the cancer cells are alive.
