Biology: The study of Life 1.1

• How living things interact

• Helps us solve problems

• Helps us appreciate diversity of living things and their interactions.– Biosphere: ______________– Biodiversity: ____________

• Species: _________________

Characteristics of living thingsSection 1.1

• Cells• Need for energy

– Metabolism: all the chemical reactions in a body

• Response to Environment• Reproduction and development

– Genetic material: DNA/RNA

Brainstorm Activity

• Fire vs. Goldfish.

• Proof of life.

Themes in Biology 1.2• All levels of life have related parts: systems

– From circulatory systems to ecosystems

• Structure and function are related• Evolution leads to Unity and diversity

through Adaptation• Homeostasis

1.3 Scientific Thinking and Processes

• Observation

• Hypothesis

• Testing/ Experiment– Independent variable ___– Dependent variable ___– Control– Trials– Data: quantitative/ qualitative

• Theory: explains a wide range of observations

Parts of a compound/light microscope

• Eyepiece (ocular)• Body Tube• Course and Fine Adjustment• Arm• Base• Nose Piece• Objective• Stage and Stage Clips• Diaphragm• Light Source

How do you prepare a microscope slide?• 1) Carry the microscope to your station, with one

hand supporting the arm and the other the base• 2) Clean glass slide and cover slip as well as the

lenses with lens paper• 3) Place specimen in the middle of the slide• 4) Lower the cover slip and remove excess liquid• 5) Add stain if called for

Types of Microscopes

• Compound Light Microscope

• Dissecting Microscope

• Electron Microscope (SEM/TEM)
