Biology I UNIT 1 NATURE OF SCIENCE
Science An organized way of using evidence to learn about the natural world. It is both a body of knowledge and a process.
Biology Biology is the study of life (organisms)
Characteristics of life Orderly structure or organization cells→tissues→organs→organ systems→organism 2. Reproduction species 3. Growth and Development 4. Respond to stimuli
Stimulus Response Adaptation Internal environment
Nature of Science Equipment, Procedures, and Safety
1.1 Handling, Measuring, and Storing Liquids Accuracy-a correct measurement; how close you are to the target.
Precision- reproducibility of the measurement. It also be thought of as how many decimal places are in a measurement.
Do accuracy and precision go hand in hand?
Measuring and Dispensing Liquids Graduated cylinder - accurately measures volumes of liquids, usually in mL. Read the bottom of the meniscus.
Pipettes, Syringes, Burettes Syringe
Handling and Storing Liquids Test tubes-used for mixing and handling.
Beakers and Erlenmeyer Flasks
1.2 Scientific Measurements Measuring Mass and Weight
Mass A measurement of how much matter is in an object. Is constant Unit of measure-gram Instrument of measure-balance
Triple Beam Balance
Reading a triple beam balance
Weight A measurement of the force of gravity on an object. Changes in relationship to force of gravity. Unit of measure - Newtons (N) Instrument of measure - spring scale
Measuring Length Metric rulers or meter sticks are used to determine length in meters, centimeters, or millimeters.
Determining Temperature Temperature is a measure of the average kinetic energy of particles in an object. Thermometers measure temperature in degrees Celsius ( o C)
Section 1.4 Equipment Used for Heating
Bunsen Burner Hottest part of flame
Proper Way to Hold a Test Tube Over a Bunsen Burner
Other Biological Tools
Cell Culture using Petri Dishes
Microscopes Compound light microscope Electron microscope
Equipment Used in Handling Hot Glassware
Section 1.5 Safety and Protective Equipment
Know the location of the following: Emergency eyewash station. Safety Shower Absorbent materials Biohazards container Fire Extinguisher
Common Safety Equipment
Section 1.6 Safety Procedures and Common Safety Symbols
Making Measurements in Science
Warm –up: What is the density of the block?
Lab Equipment 1. Beakers Proper Use Used for many purposes Can be heated Not used for accurate measuring.
TEKS 2(E) plan and implement (carry out) investigative procedures, including asking questions, formulating testable hypotheses, and selecting equipment.
This tool is used to measure the VOLUME of a liquid. The proper way to read this tool is at EYE LEVEL at the bottom of the MENISCUS, which is the curved.
Test Tube Used to hold dry or liquid substances.To compare experimental results.
Reason 1: helps scientists share and compare their data/ results
Equipment for Labs. Flask (Erlenmeyer Flask) Used to measure volume Good for mixing chemicals (swirling by hand)
Measuring: Using the Metric System in Science. graduated cyclinder.
LAB EQUIPMENT. Beaker used for storing and mixing liquids.
Laboratory Equipment. Erlenmeyer Flasks Beakers.
Science Lab Tools Mrs. Eddlemon 6 th Grade. Beaker a glass or plastic tool used to measure liquids. a glass or plastic tool used to measure liquids.
Scientific Equipment. Thermometer Used to measure temp. UOM will be either Fahrenheit or Celsius degrees.
