AP BIOLOGY Mrs. Henry bhenry@myimmaculatehs.org Room 312 AP BIOLOGY SUMMER WORK

WELCOME TO AP BIOLOGY 2017 - 2018!

The two main goals of AP Biology are to help you develop a conceptual framework for modern biology and to gain a deeper appreciation of science as a process (as opposed to an accumulation of facts). Because of the rapid pace of learning in the life sciences our primary emphasis is on developing an understanding of unifying concepts that connect the major topics of biology. The AP Biology Curriculum centers around the four Big Ideas and you will need to not only know these but also understand how they all relate to every aspect of biology: - Big Idea 1: The process of evolution drives the diversity and unity of life. - Big Idea 2: Biological systems utilize free energy and molecular building blocks to grow, to reproduce and to maintain dynamic homeostasis. - Big Idea 3: Living systems store, retrieve, transmit and respond to information essential to life processes. - Big Idea 4: Biological systems interact, and these systems and their interactions possess complex properties. What to do before the first day of school: • AP Biology was designed by a select group of college professors and high school science teachers to be equivalent to an introductory college biology course. Visit the College Board site (below) to explore what an AP Biology course is like: https://apstudent.collegeboard.org/exploreap?affiliateId=apcentral&bannerId=exploreap1

Finish the assignments listed below. The first assignment listed should be typed and printed out. The other assignments can be completed in way that is easiest for you. ALL WORK DUE ON THE FIRST DAY OF CLASS. Expect a test on Ecology within the first few days.

AP Biology Summer Assignment 2016 – Mandatory Assignment #2 Biology Prefixes and Suffixes Because vocabulary in this course can be a stumbling block, you need to take some time to review the scientific Latin/Greek roots that form many of our scientific terms. Print and complete the Biology Prefixes and Suffixes. Some of these should have been learned in your Biology class so hopefully most of them will just be review. It will make life in AP Biology much easier if you KNOW these prefixes and suffixes. The Prefixes and Suffixes can be found below. Due on day 1. AP Biology Summer Assignment 2016 – Mandatory Assignment #3 Review

Complete the review packet attached and have it ready to turn in on DAY ONE of the 2017-2018 year.. The new AP biology curriculum stresses the importance of being able to analyze and graph data. Graphing exercises are located at the end of this packet.

Biology Prefixes and Suffixes-The Language of Science

The main reason students find it difficult to understand science is because of all the hard to write, spell and read words. Actually, scientific vocabulary is a mix of small words that are linked together to have different meanings. If you learn the meanings of the little words, you'll find scientific vocabulary much easier to understand. Find the mean to the following Greek/Latin root words.

Graphing Practice Graphing is an important procedure used by scientists to display the data that is collected during a controlled

experiment. Line graphs must be constructed correctly to accurately portray the data collected. Many times the

wrong construction of a graph detracts from the acceptance of an individual’s hypothesis

A graph contains five major parts:

a. Title

b. The independent variable

c. The dependent variable

d. The scales for each variable

e. A legend

The TITLE: depicts what the graph is about. By reading the title, the reader should get an idea about the graph.

It should be a concise statement placed above the graph.

The INDEPENDENT VARIABLE: is the variable that can be controlled by the experimenter. It usually

includes time (dates, minutes, hours, etc.), depth (feet, meters), and temperature (Celsius). This variable is

placed on the X axis (horizontal axis).

The DEPENDENT VARIABLE: is the variable that is directly affected by the independent variable. It is the

result of what happens because of the independent variable. Example: How many oxygen bubbles are produced

by a plant located five meters below the surface of the water? The oxygen bubbles are dependent on the depth

of the water. This variable is placed on the Y-axis or vertical axis.

The SCALES for each Variable: In constructing a graph one needs to know where to plot the points

representing the data. In order to do this a scale must be employed to include all the data points. This must also

take up a conservative amount of space. It is not suggested to have a run on scale making the graph too hard to

manage. The scales should start with 0 and climb based on intervals such as: multiples of 2, 5, 10, 20, 25, 50, or

100. The scale of numbers will be dictated by your data values.

The LEGEND: is a short descriptive narrative concerning the graph's data. It should be short and concise and

placed under the graph.

The MEAN for a group of variables: To determine the mean for a group of variables, divide the sum of the

variables by the total number of variables to get an average.

The MEDIAN for a group of variables: To determine median or “middle” for an even number of values, put

the values in ascending order and take the average of the two middle values. e.g. 2, 3, 4, 5, 9, 10 Add 4+5

(2 middle values) and divide by 2 to get 4.5

The MODE for a group of variables: The mode for a group of values is the number that occurs most frequently.

e.g. 2, 5, 8, 2, 6, 11 The number 2 is the mode because it occurred most often (twice)

Rules and Tips for Graphing:

1. Always use a pencil to draw your graph. It’s easier to fix mistakes (Or use Excel!).

2. Always draw lines with a ruler. Do not freehand. Use at least half of your paper for the graph.

3. Make sure Independent Variable is on the X-axis and Dependent Variable is on the Yaxis.

4. Include all parts: Title, Axis Labels WITH Units, Legend

5. If you are graphing multiple subjects, use different colored or patterned lines and explain what they are in the

legend.

6. Choose an appropriate graph to explain your data. Examples:

a. LINE: Measuring a change in something over time

b. BAR: Comparing individuals to each other with only one data point.

c. PIE: Show percentages that add up to 100%.

PROCEDURE 1: Using the following data, answer the questions below and then construct a line graph.

Depth in meters Number of Bubbles / minute Plant A Number of Bubbles / minute Plant B

2 29 21

5 36 27

10 45 40

16 32 50

25 20 34

30 10 20

1. What is the dependent variable and why?

2. What is the independent variable and why?

4. What are the mean, median, and mode of all 3 columns of data? a). Depth : Mean____________Median__________Mode________

b). Bubble Plant A.: Mean ____________Median_________Mode________

c). Bubbles Plant B: Mean ____________Median_________Mode________

Title:

5. Come up with an explanation for the data in this graph, including the varying rates in plant A and B.

LEGEND:

PROCEDURE 2:

Diabetes is a disease affecting the insulin producing glands of the pancreas. If there is not enough insulin

being produced by these cells, the amount of glucose in the blood will remain high. A blood glucose level

above 140 for an extended period of time is not considered normal. This disease, if not brought under

control, can lead to severe complications and even death.

Answer the following questions concerning the data below and then graph it.

Time After Eating hours Glucose ml / Liter of Blood Person A Glucose ml / Liter of Blood Person B

0.5 170 180

1 155 195

1.5 140 230

2 135 245

2.5 140 235

3 135 225

4 130 200

1. What is the dependent variable and why?

2. What is the independent variable and why?

4. Which, if any, of the above individuals (A or B) has diabetes?

5. What data do you have to support your hypothesis?

6. If the time period were extended to 6 hours, what would the expected blood glucose level for Person

B?

Title:

LEGEND:

7. What conclusions can be determined from the data in graph 2?

PROCEDURE 3:

The chart to the right is the raw data of the ml of water

expelled by the contractile vacuole of a bacteria in different

types of solutions.

This data was then summarized using averages in the table

below.

Solution Baseline Saline Deionized

Average (in mL) 16.4 7.30 25.87

Standard deviation (error) 6.10 3.43 5.23

1. Construct a bar graph of the amount of water expelled for each

solution type.

2. Each group has an error value or “standard deviation”. Show this

on your graph using lines above and below each bar. Use the

example to the right of “Experiment 1” as a guide.

1. Why are averages used to construct graphs?

2. What does “standard deviation” mean?
