quarter and at the end of the year

Day 1 – Aug 21

What is the environment?

List several ways that environment influences the economy.

Day 2 – Aug 22 Define the following:

› Biodiversity› Ecological footprint› Natural resource› Sustainability› Law of supply and demand

Day 2 Define the following:

› Biodiversity – the variety of organisms in a given area, the genetic variation within a population, the variety of species in a community, or the variety of communities in an ecosystem

› Ecological footprint – a calculation that shows the productive area of Earth needed to support one person in a particular country

Day 2› Natural resource – any natural material that

is used by humans, such as water, petroleum, minerals, forests, animals

› Sustainability – the condition in which human needs are met in such a way that a human population can survive indefinitely

› Law of supply and demand – a law of economics that states that as the demand for a good or service increases, the value of the good or service also increases

Day 3 – Sept 10

Ch 2 section 1 vocab › Observation › Hypothesis› Prediction › Experiment› Variable

› Experimental group

› Control group

› Data› Correlation

Day 3 Ch 2 section 1 vocab

› Observation – process of obtaining information by using the senses

› Hypothesis – a theory or explanation that is based on observation and can be tested

› Prediction – a statement made in advance that expresses the result will be obtained from testing a hypothesis, if the hypothesis is supported; the expected outcome

› Experiment – procedure designed to test the hypothesis under controlled conditions

› Variable – a factor that changes in the experiment› Experimental group – a group that is identical to the control

group except for one factor› Control group – a group that is identical to the experimental

group but nothing is changed› Data – the information gathered through an experiment› Correlation – the linear dependence between to variables

Day 4 – Sept 16 Ch 2 section

2 vocab › Statistics› Mean › Distribution › Probability› Sample› Risk

› Model › Conceptual model

› Mathematical model

Day 4› Statistics – collection and classification of data into

numbers (%)› Mean – average value for a set of numbers› Distribution – relative arrangements of numbers of

a statistical population› Probability – chance that something will happen› Sample – selected to represent a population› Risk – probability of an unwanted outcome› Model – pattern, plan or representation designed to

show structure or working of an object, system, or concept

› Conceptual model – verbal or graphical representation

› Mathematical model – one or more equations that represent the way a system or process works

Day 5 – Sept 17

Ch 2 section 3 vocab ›Value›Decision-making model

Day 5

› Value – principle or standard that an individual considers to be important

› Decision-making model – a conceptual model that provide a systematic process for making decisions

Day 6 – Sept 19

Explain the statement “a good scientists is one who asks the right questions”.

How are statistics helpful for evaluating information about the environment?

How does making a table help you evaluate the values and concerns you have when making a decision?

Day 6 Explain the statement “a good scientist is one

who asks the right questions”. When an observation warrants further examination, a good scientist knows what questions to investigate to fully understand the observation

How are statistics helpful for evaluating information about the environment? Statistics help people quantify and analyze different kinds of information, including information about the environment.

How does making a table help you evaluate the values and concerns you have when making a decision? Making a table can help in decision-making situations by organizing all the + and – consequences of a decision for comparison
