Protocol for measuring ground level ozone - Guided Research Protocol
After you have gather background information and made preliminary observations it is time to formulate a hypothesis. A hypothesis is merely a tentative explanation proposed to account for the observed phenomena. You are speculating on how natural events will turn out, based on what you know. "Science is systematic in method because it seeks a system of prediction." That prediction is the hypothesis. Any hypothesis selected or formulated must be testable. Experiments generally test hypotheses by testing the validity of the predictions or conclusions derived from them. The primary purpose of designing scientific experiments is to test the proposed hypotheses.
It is important to know that hypotheses are never proven - they are either supported or not supported by the data from the experimental results. Borrowing from statistics, two types of hypotheses are used simultaneously: null (H0) and alternative (H1) . H0 states that events will not change, not differ and H1 states that events will change, differ, from some baseline standard or control conditions. This change (dependent variable) predicted by H1 will be due to the occurrence of an experimentally controlled variable (independent variable).
Hypothesis for this Guided Research
H0: There is no measurable relationship between the high temperature of the day and the level of ground-level ozone.
The experiment to test these hypothesis uses the Vistanomics, Ecobadge Ozone Monitoring Kits, distributed by Wards Natural Science (1-800-962-2660).
The test cards contained in this package react when exposed to air. Using specially treated papers that react at different rates, the Eco Badge provides readings for peak short term (one hour) and average long term (eight hour) periods. After eight hours, the long term reading gives the average level of exposure for that period. It does not provide minute-by minute readings of increase or decreases in ozone levels.
To use the Eco Badge for KanCRN data collection:
