Description

Module 1: 1. Explain the process of science. List of processes and methods used by scientists globally when conducting an experiment/research. It starts off with an observation-question-hypothesis-,prediction(if and then)-experiment-results. 2. What’s the “hypothesis”? Describe the criteria of a good "hypothesis". A hypothesis is a suggested explanation for an event, it must be falsifiable and testable 3. Describe the process of scientific method and develop one example to explain (a) how scientists make observations, (b) develop the hypothesis, (c) design the experiment, (d) collect the data and accept or reject the hypothesis based on the collected evidence. 4. Define and be able identify the independent variable, the dependent variable, and control vs. experimental groups in a controlled experiment. Explain the importance of a controlled experiment. Independent variable= manipulated throughout the experiment dependent variable= measured

An experimental group, also known as a treatment group, receives the treatment whose effect researchers wish to study, whereas a control group does not. They should be identical in all other ways 5. What is considered as a scientific theory? Explain the differences between hypothesis, everyday's theory and a scientific theory. 6. Describe how cells form the basic unit of all life and provide one example to explain "emergent properties" in biological sciences An emergent property is a property which a collection or complex system has, but which the individual members do not have. Ant and bee colonies cannot function with just individual workers. Brain.

7. List the basic, common characteristics shared by all living things. Made of cells, response to stimuli: plants bending towards sunlight Reproduction: babies growth and development: growing and developing by genes Regulation: Nutrient transport and gene expression Homeostasis: Maintaining constant internal conditions energy processing: food and the sun 8. Levels of organization

atom(oxygen) - molecule(water)- macromolecules(phospholipids)- cell- tissue(epithelial tissue)- organ(lung)- organ system(respiratory system)- organism(lion)- population(lion pride) - community(lions and zebras)- ecosystem(lions, zebras, trees)- biosphere(life on earth)...
