General Information Use a composition notebook Have 2 colors of ink or a highlighter Write the question and the answer Include the date and the number for each bellringer Bellringers will be collected each 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

Ch 2 section 1 vocab Day 3 – Sept 10 Variable Experimental group Observation Control group Hypothesis Prediction Data Experiment 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 Risk Model Statistics Conceptual model Mean Mathematical model Distribution Probability Sample

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
