<p> Unit 1 Physical Science</p><p>Unit 1 – Physical Science NOTES - Page 1 of 9 NOTE Packet</p><p>Name ______period _____</p><p>Unit 1 – Physical Science NOTES - Page 2 of 9 SCIENCE 9 – Unit 1 I) Outcome 2 --- Scientific Method All disciplines of Science (Biology, Chemistry, Physics, Geology, etc ….) are based upon: “______” O______& E______</p><p>Because solid science relies upon “O & E”, science must have a consistent process to make ______and collect ______.</p><p>This process is called the ______</p><p>Unit 1 – Physical Science NOTES - Page 3 of 9 SCIENTIFIC METHOD … steps of the Scientific Method A) Determine the ______(or ______) to be tested. The purpose is written with BOTH the ______and ______variables in it.</p><p>Example: How does ______(independent variable) affect ______(dependent variable)? Become educated about your topic (do research or perform experiments) Example: Research the data that already has been collected about the affects of sunlight on plant growth.</p><p>B) Form a ______that answers the question stated in the Purpose. Hypothesis =______. Example: I think the plant that is exposed to sunlight will grow faster than the one that doesn’t receive sunlight. My research suggests that sunlight is necessary for plant growth.</p><p>C) EXPERIMENT … Preparing and Performing the Experiment(s) <><>TEST GROUPS (two types of test groups) 1) ______TEST = Part of the experiment with the ______taken out or changed so the control-test’s results can be compared to the results from the experimental test(s). 2) ______TEST(S) = Part(s) of the experiment that has both the independent and dependent variables in it.</p><p>Unit 1 – Physical Science NOTES - Page 4 of 9 Outcome 2 NOTES continued . . . A) INDEPENDENT VARIABLE - The ______of the experiment. B) DEPENDENT VARIABLE = The ______of the experiment. Example: Control TEST: Plant B – Gets no sunlight for 12 days. Experimental TEST: Plant A is allowed sunlight everyday for 12 days. - Independent variable of this example (cause): ______. - Dependent variable of this example (effect): ______.</p><p>D) DATA COLLECTION AND ANALYSIS. - Data = ______. - ANALYSIS: Analyzing data often includes creating data tables and graphs to help make sense of the data… looking for patterns. - WRITING THE ANALYSIS: When you write an analysis you explain the patterns your data shows … in ______… without ______.</p><p>Example Analysis: Plant A grew 6 cm in 12 days (from 6cm to 12 cm). Plant B grew 2 cm in 12 days (from 6 cm to 8cm).</p><p>E) Make a CONCLUDING STATEMENT that has TWO parts: PART 1 . . . - ______. PART 2 . . . ______OR specific references to the data.</p><p>Example: (PART 1) The data suggests that ______. Unit 1 – Physical Science NOTES - Page 5 of 9 (PART 2) Plant A was given sunlight for ______in that time. Plant B was not allowed sunlight and grew only ______.</p><p>Unit 1 – Physical Science NOTES - Page 6 of 9 II) Outcome 3 - Metric Measurement Basic Unit Symbol Tools Used length ______mass ______</p><p> liquid volume ______solid ______volume ______1 cc = ______</p><p>Temperature ______</p><p> o Freezing of H2O = ______C o Boiling of H2O = ______C</p><p>Density ______</p><p>Density = ______/ ______</p><p>Unit 1 – Physical Science NOTES - Page 7 of 9 III) OUTCOME 4- Metric Converting</p><p> basic kilo hecto deka unit deci centi milli ______meter ______liter ______gram To be able to convert in the metric system you must know the order of the prefixes above.</p><p>PREFIX ORDER Use this silly saying to help remember the metric order:</p><p>“kick” “her” “duck” “under” “daddy’s” “cement” “mixer” (kilo) (hecto) (deka) (basic unit) (deci) (centi) (milli)</p><p>Unit 1 – Physical Science NOTES - Page 8 of 9 Outcome 4 NOTES continued . . . STEPS TO CONVERTING:</p><p>>> Let’s use the example problem: 25.0 meters is how many centimeters? OR 25 m = ______cm</p><p>1) Find what number and unit you are given. This is the starting point. - In the example, we are given 25.0 (m) meters Starting point kilo hecto deka unit deci centi milli meter</p><p>2) Find what unit you need to convert to. This is the ending point. - In the example, we need to convert to cm (centimeter)</p><p>Ending point kilo hecto deka unit deci centi milli</p><p>3) Determine the direction you need to move AND count how many places you need to move. Starting point Ending point kilo hecto deka unit deci centi milli meter</p><p>- In the example, we move two places to the right, from meter to centi</p><p>4) Move the decimal point two places to the right.</p><p>25.__ __m = 2500. cm Unit 1 – Physical Science NOTES - Page 9 of 9</p>
