Background: Scientific inquiry in biology starts by observing the living species around us. Science is a way of knowing. It is not the only way, but it is a good way. Other ways of knowing include mathematics, logic, history, philosophy, and theology.What separates science from the other methods of seeking truth is that it is testable (i.e. one can devise experiments to test the validity of an idea); it is falsifiable (i.e. an experiment can reveal if an idea is false); and, it involves natural causality (i.e. the method involves and depends upon the natural laws of the universe which cause things to happen in a predictable and repeatable manner.)
Observation: Scientific inquiry begins when something interesting gets your attention.
Question: Following an observation, a question arises in your mind. It may be something like: “I wonder what…? Or “I wonder how …? Or, “I wonder why…?
Assignment details:
In this assignment, we will take a look at science and the scientific method. Then, you will design a (pretend) scientific study to answer a specific question based upon an observation.
First, choose ONE of the following Observations /Questions:
Option A:
Observation: During the winter, you spread salt daily on your driveway to melt the snow. In the springtime, when the lawn begins to grow, you notice that there is no grass growing for about 3 inches from the driveway. Furthermore, the grass seems to be growing more slowly up to about 1 foot from the driveway.
Question: Might grass growth be inhibited by salt?

The Cardiovascular System
The cardiovascular system (also known as the circulatory system) is composed of the organs and tissues involved in circulating blood and lymph through the body. The heart, blood, and blood vessels make up the cardiovascular system, which services all of the cells in the body. Wastes are taken away and exchanged with oxygen and food nutrients. Common problems of the cardiovascular system include aneurysms, atherosclerosis, heart disease, high blood pressure, and varicose veins.
In this lab, you will address the following:
Identify the major endocrine glands and tissues
Demonstrate an understanding of the cardiovascular and the circulatory system
Apply background knowledge to the major respiratory structures as well as describe the functions of each
You are to write a 1-page Lab Report using the Scientific Method sections below. Your Pearson report is your data to support your report. Attach the Pearson report as part of your lab report results. The Pearson questions are to help you understand the topic and may be used in your report to support your findings.
Complete the steps of the scientific method for your lab option choice. Use these headings in your paper, please.
Purpose:
State the purpose of the lab.
Introduction:
This is an investigation of what is currently known about the question being asked. Use background information from credible references to write a short summary about concepts in the lab. List and cite references in APA style.
Hypothesis / Predicted Outcome:
An hypothesis is an “educated guess.” Based on what you have learned and written about in the Introduction, state what you expect to be…
