BIOLOGICAL SCIENCES: 9. THE STUDY OF LIFE BY USING THE SCIENTIFIC METHOD. THE SCIENTIFIC METHOD a. OBSERVATION – Bacteriophages are virus that attack and kill bacteria. b. QUESTION - Could it also be used to kill bacteria that are living inside an organism’s body, instead of using antibiotics? c.1. HYPOTHESIS (of interest) – Bacteriophage will kill E.coli injected in mice c. PREDICTION: if bacteriophage viruses are able to kill E.coli , MICE WILL SURVIVE. c.2. HYPOTHESIS (NULL) – Bacteriophage will NOT kill E.coli injected in mice PREDICTION: bacteriophage will NOT kill E. coli and MICE WILL DIE of infection by E. coli. Null Hypothesis – the bacteriophage Hypothesis of Interest – the Will NOT kill E. coli. bacteriophage WILL kill E. coli Prediction: THE MICE WILL DIE Prediction: THE MICE WILL SURVIVE d. If Statistical Analyses of the data shows that there was an effect, MICE SURVIVED, then one has to reject the NULL hypothesis and ACCEPT the hypothesis of interest. (THERE is always an acceptable margin of error in these analyses, ranging from 5% to 10% depending on the statistical analysis used). e. CONCLUSION - HYPOTHESIS (Alternative) ACCEPTED Bacteriophage will kill E.coli injected in mice. Prediction: mice survive the E.coli infection. 10. SCIENCE, TECHNOLOGY AND SOCIETY

MATTER a. Matter is anything that takes up space and has mass. b. Mass is the amount of matter in an object c. Weight is the force that gravity exerts on the mass of an object 3. CHEMICAL ELEMENTS a.
