 Standard 2: Structure and Function in Living Systems – Living systems at all levels of organization demonstrated the
complementary nature of structure and function. The student will engage in investigations that integrate the process standards and lead
to the discovery of the following objectives:
2.1 Living systems are organized by levels of complexity (i.e., cells, tissues, organs, and/or systems).
2.2 Specialized structures perform specific functions at all levels of complexity (e.g., leaves on trees and wings on birds).

 Standard 3: Reproduction and Heredity – Reproduction is the process by which organisms give rise to offspring.
Heredity is the passing on of traits to offspring. All organisms must be able to grow, reproduce, and maintain stable internal conditions
while living in a constantly changing eternal environment. The student will engage in investigations that integrate the process standards and
lead to the discovery of the following objectives:
3.1 Characteristics of an organism result from inheritance and from interactions with the environment.
3.2 Reproduction is essential for species survival. Individual organisms with certain traits are more likely to survive and produce offspring.

 Standard 4: Behavior and Regulations – All organisms must be able to grow, reproduce, and maintain stable internal conditions
while living in a constantly changing external environment. Behavioral response is a set of actions determined in part by heredity and in
part by experience. The student will engage in investigations that integrate the process standards and lead to the discovery of the following objectives:
4.1 Living organisms strive to maintain a constant internal environment (i.e., temperature regulation).
4.2 Living organisms have physical and/or behavioral responses to external stimuli (e.g., hibernation, migration, plant growth).

   Process Standard 1: Observe and measure – Observing is the first action taken by the learner to acquire new information about an
object, organism, or event. Opportunities for observation are developed through the use of a variety of scientific tools.
Measurement allows observations to be quantified. The student will accomplish these objectives to meet this process standard.
PS1.1 Identify qualitative and/or quantitative changes given conditions (e.g., temperature, mass, volume, time, position, length)
before, during, and after an event.
PS1.2 Use appropriate tools (e.g., metric rulers, graduated cylinders, thermometers, balances, spring scales, stopwatches)
to measure objects, organisms, and/or events.
PS1.3 Use appropriate System International (SI) units (i.e., grams, meters, liters, degrees Celsius, and seconds);
and SI prefixes (i.e., micro- milli-, centi-, and kilo-) when measuring objects, organisms, and/or events.

  Process Standard 2: Classify – Classifying establishes order. Objects, organisms, and events are classified based on
similarities, differences, and interrelationships. The student will accomplish these objectives to meet this process standard.
PS2.1 Using observable properties, place an object, organism, and/or event into a classification system (e.g., dichotomous keys).
PS2.2 Identify properties by which a set of objects, organisms, or events could be ordered.

  Process Standard 3: Experiment – Experimenting is a method of discovering information. It requires making observations and
measurements to test ideas. The student will accomplish these objectives to meet this process standard.
PS3.1 Ask questions about the world and design investigations that lead to scientific inquiry.
PS3.2 Evaluate the design of a scientific investigation.
PS3.3 Identify variables and/or controls in an experimental setup (i.e., tested, experimental, and measured variables.
PS3.4 Identify a testable hypothesis for an experiment.
PS3.4 Design and conduct experiments.
PS3.5 Recognize potential hazards and practice safety procedures in all science activities.

  Process Standard 4: Interpret and Communicate – Interpreting is the process of recognizing patterns in collected data
by making inferences, predictions, or conclusions. Communicating is the process of describing, recording, and reporting
experimental procedures and results to others. Communication may be oral, written, or mathematical and includes organizing ideas,
using appropriate vocabulary, graphs, other visual representations, and mathematical equations.
The student will accomplish these objectives to meet this process standard.
PS4.1 Report data in an appropriate method when given an experimental procedure or data.
PS4.2 Interpret data tables, line, bar, trend, and/or circle graphs.
PS4.3 Evaluate data to develop reasonable explanation, and/or predictions.
PS4.4 Accept or reject hypotheses when given results of an investigation.
PS4.5 Communicate scientific procedures and explanations.

  Process Standard 5: Inquiry – Inquiry can be defined as the skills necessary to carry out the process of scientific or systemic thinking.
In order for inquiry to occur, students must have the opportunity to ask a question, formulate a procedure, and observe phenomena.
The student will accomplish these objectives to meet this process standard.
PS5.1 Use systematic observations, make accurate measurements, and identify and control variables.
PS5.2 Use technology to gather data and analyze results of investigations.
PS5.3 Review data, summarize data, and form logical conclusions.
PS5.4 Formulate and evaluate explanations proposed by examining and comparing evidence, pointing out statements that go beyond evidence,
and suggesting alternative explanations.
