1. Chapter 1 Biology:Investigating the Cycles of Life Lab Biology Mrs. Campbell

2. Lesson 1 What is Biology? Biology – the study of life Organism – a living thing; one of many different forms of life Biologist – a person who studies life or biology Cycle – a course or series of events or operations that repeats

3. Lesson 2 Energy and Growth Cycles Energy Cycles Energy – the ability to do work. Energy is found in many different forms. Transform – to change form. Law of Conservation of Energy states that energy can not be created or destroyed. Heat – a form of energy resulting from the motion of particles in matter.

4. Lesson 2, Energy and Growth Cycles con’t Growth Cycles Reproduction – the process of making new life. DNA – Deoxyribonucleic acid is a chemical in an organism that contains the instructions for life. Cell – the basic unit of life. Proteins – a chemical used by cells to grow and work.

5. Lesson 3 Evolutionary and Ecology Cycles Evolution – the changes in a population over time. Species – a group of organisms that can reproduce with each other. Speciation – the process of making a new species. Extinct – when no members of a species are alive.

6. Lesson 3, con’t Evolutionary and Ecology Cycles Adaptation – an adjustment to environmental conditions. Environment – an organism’s natural and man-made surroundings. Ecology – the study of interactions among living things and the nonliving things found in any particular area.

7. Lesson 3, con’t Evolutionary and Ecology Cycles Ecologist – a person who studies ecology. Ecosystem – all of the living and nonliving things found in a particular area. Stimulus – anything to which an organism reacts.

8. Lesson 4 The Scientific Method Specimen – a sample; an individual item or part considered typical of a group or whole. Scientific Method – a series of steps used to test possible answers to scientific questions. Observation – Looking at the world around us, watching life.

9. Lesson 4, con’t The Scientific Method Question – When scientists see something they don’t understand, they ask a question and try to find an answer. Hypothesis – an educated guess. Experiment – the procedure used to test whether a hypothesis is correct or not. Control Group - the set-up in the experiment that has no factor or variable to be tested.

10. Lesson 4, con’t The Scientific Method Experimental Group – the same group as the control group, except for one factor, or variable, to be tested. Variable – the factor that is being tested in an experiment. Data – information collected from experiments.

11. Lesson 4, con’t The Scientific Method Analysis – making sense of the results of an experiment. Communication – After checking results, scientists share the results with others. Theory – a well-tested explanation that makes sense of a great variety of scientific observations.
