Unit 1: PACKET CHEMISTRY OF LIFE
This packet is designed to help you understand several concepts about THE CHEMISTRY OF LIFE.
As you practice the exercises on each handout, you will be able to:
CHEMISTRY OF LIFE: Develop and use a model to illustrate the hierarchical organization of interacting systems that provide specific functions within multicellular organisms.
HS10-LS1-2.1 Describe the characteristics that all living things must demonstrate in order to be
considered alive: made of cells, use energy, reproduce, respond to change, maintain internal
balance, display organization, evolve, grow & develop.
HS10-LS1-2.2 Identify the parts of an atom & all subatomic particles (name, charge & purpose).
HS10-LS1-2.3 List common elements found in living things (CHNOPS). HS10-LS1-2.4 Explain the properties of water that make life on Earth possible.
Record this packet in the Table of Contents for Unit 1. This will be the first “HANDOUT.”
Contained in this Packet:
1. Graphing & Analyzing Data Practice 2. Can You Answer These Questions About the Atom? 3. What Makes Water a Polar Molecule? 4. Sticky Water Essay Practice
UNIT 1: Graphing and Analyzing Data Practice
Scientific investigations often gather both qualitative and quantitative data. This data is useless unless it can be interpreted in a meaningful way. Constructing a graph is one way to interpret gathered data and look for trends or patterns. In this packet, there are several scientific investigations with already collected data. You will be asked to:
1. Apply the scientific method to a real world problem. (HS10-PS1-5.2) 2. Identify the following items in an experimental investigation: independent variable,
dependent variable, constants, experimental group, control group. (HS10-PS1-5.5) 3. Construct graphs with appropriate identifying labels. (HS10-ESS2-5.2)
As you work on this packet, make sure to:
Read the information in each scenario carefully and highlight important information (this is SIDE NOTES).
List the independent and dependent variables for all except #8. DESCRIBE the experimental group and control group for #1, #3, #4 Using the guidelines in Graphing Tips, draw the appropriate graph (line or bar) to
represent the data accurately.
GRAPHING TIPS
The graph should contain 5 major parts: title, independent variable, dependent variable, scales for each variable, and a legend.
1.) TITLE: placed directly above the graph short and sweet includes both independent and dependent variables describes the represented information
2.) INDEPENDENT VARIABLE:
variable that the experimenter changes x-axis
3.) DEPENDENT VARIABLE: variable directly affected by the independent variable y-axis
4.) SCALES for each Variable:
must include all data points each block should have a consistent amount or increment & be easy to count (ex: 2,4,6 or 5,10,15) allow as much of the graph to be taken up as possible
5.) LEGEND:
placed directly below or to the side of the graph short, but descriptive
used to distinguish between different types of data in the same graph/

UNIT 1: Can You Answer These Questions About THE ATOM?
The questions below will assist in mastery of the following Standard and Learning Target:
CHEMISTRY OF LIFE: Develop and use a model to illustrate the hierarchical organization of interacting systems that provide specific functions within multicellular organisms.
HS10-LS1-2.2 Identify the parts of an atom & all subatomic particles (name, charge and purpose)
1. USE YOUR NOTES: What is an atom?
2. IN YOUR OWN WORDS: What is an atom?
3. The composition of an atom is important. The particles that make up an atom are called subatomic particles.
In the table below: Name of each subatomic particle Charge for each subatomic particle
Function of each subatomic particle Location of each subatomic particle
Name Charge Location Function
3. Identify the 2 different regions found in an atom AND the particles found in each area with charges. 4. In each of the pictures below, identify the following items:
# of valence electrons Circle/box all valence electrons
region name: _____________________ particle(s) name(s) & charge(s):
region name: ________________________ particle(s) name(s) & charge(s):
A.
B..
# of valence electrons: _______ Did you circle/box all the valence electrons?
# of valence electrons: _______ Did you circle/box all the valence electrons?
UNIT 1: What Makes Water a POLAR Molecule?
CHEMISTRY OF LIFE:
Develop and use a model to illustrate the hierarchical organization of interacting systems that provide specific functions within multicellular organisms. HS10-LS1-2.4 Explain the properties of water that make life on Earth possible.
