Biology Name _Kylie MJC Scientific Investigation Introduction: Science is a natural process of investigating living and non-living things leading to organized knowledge. This means that science is an activity and one in which we use our senses to participate in. We use our senses of seeing, hearing, tasting, touching and smelling to collect information (data) from our environment. Science involves the collection of data and then conclusions are made based on that data. These conclusions often generate further questions for investigation. As new questions are generated, scientists make hypotheses that can then be tested in an organized and methodical unbiased way; data collected is then used to make further conclusions. Scientists then report their results and conclusions to other scientists and citizens. Steps in the scientific method: Observations à Questions à Hypothesis à Experiment à Results (Data Collection) à Conclusions à New Questions and reporting findings to others. You will do some of these activities at home and some in lab when we return to class next week. Materials Needed at home: Metric Ruler (measures in meter, centimeter, or millimeter units), products in your kitchen and bathroom. Metric System and Measurement: Measurement of Distance (length) - The meter 1 meter (M) = 100 Centimeters (cm) or 1000 millimeters (1000mm) or 1,000,000 micrometers (µm) 1cm = 0.01m or 10mm or 10,000 µm 1 µm = 1 x 10 -6 or 0.0001cm or 0.001mm Measurement of Volume: 1 liter (L) = 1000 milliliters (mL) 1mL = 0.001L Measurement of Mass: 1 gram (g) = 1000 milligrams (mg) 1 kilogram (kg) = 1000 grams (g) Measurement of Temperature: 100°C = Boiling point for water 37°C = Normal body temperature for humans 0°C = Freezing point for water
Making Measurements: Make measurements labeled at home before coming to class. Using a metric ruler, meter stick, Celsius thermometer, graduated cylinders, beakers or triple beam balance make the following measurements. Make your measurements using the unit of measurement in the first column. Then make conversions to the other units listed. Use the tool on the last page to help you with the conversions. Temperature San Francisco today 16.1°C __ Temperature where you are in _Modesto (list town you are in) 17°C __ Metric Mass of dry good you have at home (sugar, flour, beans, pasta, etc.) 0.01 kg 10 g Mass of 1ml of Water (ask Google, Siri or Alexa) 1 g 1000 mg Diameter of penny 19.05 mm 1.90 cm Length of your index finger 88.9 mm 8.89 cm Your height 177.55 cm 1.78 m 12oz. aluminum can of soda 354.88 mL 0.35 L List the name of a cereal and its mass in grams Chex 43 g 43,000 mg List the name or a cleaning product and its volume in mL Windex 680.19 mL 0.68 L Raw Data and Calculations: Post your height in the discussion, “Student Height and Finger Length” and then gather data from the posts of 7 other students. Using raw data obtained by yourself and 7 other students fill in the following table and make the calculations required. Student Height (cm) Length of Student Index Finger (cm) Student 1 165 cm 8.5 cm Student 2 154.94 cm 8.2 cm Student 3 172 cm 8.6 cm Student 4 175 cm 10.2 cm Student 5 178 cm 8.1 cm Student 6 190.5 cm 9.2cm Student 7 165 cm 8.2 cm Student 8 167 cm 9 cm
Average 170.93 cm 8.75 cm 1. Raw data obtained from 8 different individuals is listed in the table above. This raw data was used to make a calculation (the average). What is the difference between “raw data” and a “calculation”? Raw data is better to use and is more accurate because it isn't processed or rounded. 2. Would you expect all students’ averages to be the same in this class? Explain your answer. No, because they could have used 8 different people than the 8 people I used. Construction of a Line Graph: Using the raw data from the table, plot each of the 8 students’ height and finger length. One point on the graph will consist of both height and finger length for one student. There should be a total of 8 points on your graph when you are finished. Blue diamonds are an example.
