Scientific Method

Throughout this unit you will learn the steps of the scientific method.  You will also learn how to follow these steps during labs.

The Scientific Method
1.  Identify the Problem
2.  Form a Hypothesis
3.  Create and Experiment
4.  Perform an Experiment
5.  Analyze the Data
6.  Communicate the Results

Independent Variable:  the condition that is being changed
Dependent Variable:  the part of the experiment that is affected by the independent variable
Control:  the part of the experiment that is not tested and is used for comparison 
Variable:  the part of the experiment that can vary or change
Data:  information gained from completing and experiment
Conclusion:  summary of the results from the experiment 

We will be using a new piece of technology to practice measuring. Gizmos is a web based opportunity for students to explore hands on lab experiences. My goal is to do 1 virtual lab per Unit.

Throughout the Chemistry Unit, you will learn about how atoms behave in solids, liquids, and gasses as well as the changing states of matter.  You will also learn the symbols of the 30 most common elements and how to locate these elements on the Period Table.  During this unit, you will perform the Chemical Reactions Lab, the Conductivity Lab, and the Phases of Matter Lab.

   Throughout the Ecology Unit, students will learn about societal issues such as global warming, and ozone depletion as well as the effects of water and air pollution on the environment.  We will explore renewable and nonrenewable energy sources, our carbon footprint, and acid precipitation. Relationships among organisms within ecosystems, such as mutualism, commensalism, and parasitism, will also be learned.

Throughout the Astronomy Unit, students will learn about the organization of our universe, the different types of galaxies within the universe, the classification of stars on the H-R Diagram, and the many constellations in our night sky, focusing on the circumpolar constellations.  Students will also learn about the Sun and be able to recognize how the Sun's intense magnetic field causes prominences, flares, sunspots, and CME's.  The study of the planet compositions as well as their satellites will be studied as well.  Students will also learn about the history of space missions, beginning with the launch of Sputnik I by the Soviet Union.
