Big Idea 4:
Biological systems interact, and these systems and their interactions possess
complex properties.
Enduring Understandings:
• 2D1: All biological systems from cells and organisms to populations,
communities, and ecosystems are affected by complex biotic and abiotic
interactions involving the exchange of matter and free energy.
• 2E3: Timing and coordination of behavior are regulated by various
mechanisms and are important to natural selection.
• 4A6: Interactions among living systems and with their environment result
in the movement of matter and energy.
• 4B3: Interactions between and within populations influence patterns of
species distribution and abundance.
Learning Objectives:
• 2.22 The student is able to refine scientific models and questions about
the effect of complex biotic and abiotic interactions on all biological
systems, from cells and organisms to populations, communities and
ecosystems. (2D1 &SP 1.3, 3.2).
• 2.23 The student is able to design a plan for collecting data to show that
all biological systems (cells, organisms, populations, communities and
ecosystems) are affected by complex biotic and abiotic interactions (2D1
& SP 4.2, 7.2).
• 2.34 The student is able to analyze data to identify possible patterns and
relationships between a biotic or an abiotic factor and a biological system
(cells, organisms, populations, communities, or ecosystems) (2D1 & SP
5.1).
• 2.38 The student is able to analyze data to support the claim that
response to information and communication of information affect natural
selection (2E3 & SP 5.1).

•
2.39 The student is able to justify claims, using evidence, to describe how
timing and coordination of behavioral events in organisms are regulated
by several mechanisms (2E3 & SP 6.1).
2.40 The student is able to connect concepts in and across domain(s) to
predict how environmental factors affect response to information and
change behavior (2E3 & SP 7.2).
4.14 The student is able to apply mathematical routines to quantities that
describe interactions among living systems and their environment that
4.15 The student is able to use visual representation to analyze situations
or solve problems qualitatively to illustrate how interactions among living
systems and with their environment result in the movement of matter and
energy (4A6 & SP 1.4).
4.16 The student is able to predict the effects of a change of matter or
energy availability on communities (4A6 & SP 6.4).
4.19 The student is able to use data analysis to refine observations and
measurements regarding the effect of population interactions on patterns
of species distribution and development (4B3 & SP 5.2).

General Safety Precautions:
(Copy the headings in your lab notebook, then follow the instructions answering
the questions in your notebook along the way)
The Investigations:
Getting Started:
o Copy the procedure heading in your lab notebook then read and list the
various types of taxis in your lab notebook.
o Record each step with any corresponding answers to questions in your lab
notebook.
o Step 6 requires a prediction of what the flies will prefer based on your
knowledge of fruit flies. Write your hypothesis in an if …(independent
variable)…then…(dependent variable)…because…(reason)format.
o Step 12 requires a chi-squared analysis of your results. Show your work
for this calculation within your lab notebook.
o Step 12 also requires you to construct a class preference table within your
lab notebook.
(Copy the Designing and Conducting Your Investigation heading in your lab
notebook. Choose a question listed to investigate or one of your own to test)
Designing and Conducting Your Investigation:
(Read this section of your lab packet, then design and conduct your own
experiment. Make sure you document the following in your lab notebook:
o Problem (in the form of a question)
o Identification of variables (independent, dependent, and constants)
o Hypothesis, if (independent variable) then (dependent variable) …
because (reason)
o Materials (list)
o Procedure (numbered sequence of steps)
o Results (data tables/graphs)
o Analysis of results (paragraph form, full sentences that makes sense to
you and the reader)
o Refer back to the initial question (problem)
o Perform a chi squared analysis
o Was your hypothesis supported or refuted by your data? Couple
your answer with data and discussion.
o What are some possible sources of error that might affect the
validity of the data? Make recommendations to eliminate these
errors.
o What specific question(s) do you have for future experimentation?
(Copy the following headings in your notebook)
Analyzing Results:
(Discuss and record the answers to the questions as a class, each group will then
share their experiments/results.)
Evaluating Results:
