What is the importance of the 7 environmental principles?
- Guide for lawmakers, judges, and decision-makers in formulating policies
- Environmental principles work together to ensure high environmental standards by directing lawmakers and other decision-makers to interpret the law.
Enumerate the 7 environmental principles
- Everything is connected to everything else
- Everything must go somewhere
- Nature knows best
- Everything changes
- All forms of life are important
- Ours if a finite earth
- We are the stewards of the environment
What is the systematic process, steps/procedures to answer or solve a specific problem or phenomena?
Scientific Method
Enumerate the steps of the scientific method
- Problem (Observation)
- Research (Related studies about the problem
- Make hypothesis (Predict possible results
- Conduct the Experiment (Prove your Hypothesis)
- Draw Conclusions (Analyze Results)
- Share results (Publication)
What step of the scientific method is being perceived by the five senses, directly or indirectly?
Problem (Observation)
Process of gathering and analyzing information to increase our understanding of a topic or problem you want to study.
Research (Related studies about the problem)
Reliable sources of research/ related studies about the problem:
Scientific Journals, Online sources that are credible
Eliminates possible duplication of the topic you want to study or give you more background about the problem, see if there are really relationships or none.
Research (Related studies about the problem)
A tentative answer or a “wise guess” about an observed phenomena or research problem being solved.
Make Hypothesis (Predict possible results)
It is often an if-then statement and very specific
Hypothesis
Data that includes descriptions, historical facts and events, perception (survey, interview)
Qualitative Data
Data that includes numbers, everything that can be represented or measured in quantity of number.
Quantitative Data
Identify the type of variable: thing that you changed
Independent variable
Identify the type of variable: the thing that you measure
Dependent variable
Identify the type of variable: variable to be manipulated
Experimental group
Identify the type of variable: normal state of what is being studied
Control group
A statement based on the results and analysis of the experiment, measurements, and observations. It can either conclude or negate your hypothesis and possible future research that may improve results.
Draw Conclusions (Analyze Results)
Can be a good material for others who will be doing the same study in the future.
Share Results (Publication)
What is the etymology of the word environment?
French word “environer” meaning to surround or encircle
What is the definition of environment?
Encompasses everything “totality of the surroundings”
A specific community of living organisms interacting with each other and their environment within a defined boundary.
Ecosystem
What are the two types of environment?
Natural
Man-made
What are the two components of an environment?
Abiotic Factor (nonliving components)
Biotic Factor (living components)
What are included in the abiotic factor?
lithosphere (solid)

Population
Community
Ecosystem
Biosphere
The basic unit of life.
Cell
A group of the same cells that have common function and structure
Tissue
A group of tissues of the same structure to perform specific functions
Organ
A group of organs that work together in the body to perform a complex function
Organ System
An individual form of life
Organism
A group of the same organisms of the same species that live together in an area at the same time and are capable of reproduction
Population
Are associations of different populations of different species living and interacting at the same place at the same time
Community
A community of living organisms from different kinds of species interacting with the nonliving components in a defined boundary
Ecosystem
Where all forms of life exists
Biosphere
A model that illustrates how energy (sun) is transferred to one organism to the other.
Energy Flow
The study that deals into this energy transfer
Energetics
Biotic organisms that create their own food
Autotrophs/ Producers
Process by which plants use sunlight, water, and carbon dioxide to create their own food
Photosynthesis
Process by which food (glucose) is made by bacteria using chemicals as energy source
Chemosynthesis
Organisms that cannot make their own food, hence, they must ingest other living organisms
Heterotrophs/ Consumers
A linear view of who eats whom in an ecosystem
Food Chain
The feeding relationships in organisms
Food Chain
A network of interconnected food chains within an ecosystem, wherein it shows energy and nutrients are transferred from one organism to another
