           Chemical Reactions can be Classified

                 1. Synthesis (less complex to more complex)

                 2. Decomposition (more complex to less complex)

                 3. Combustion (form carbon dioxide and water)

           Rates of chemical reactions can vary

                 2. Using Coefficients to balance chemical equations

                 3. Using conservation of mass

Chapter 3.3 Chemical reactions involve energy changes

           Chemical reactions release or absorb energy

                 1. Exothermic (release energy)

                 2. Endothermic (absorb energy)

                 3. Exothermic and endothermic reactions work together to supply energy

Chapter 3.4 Life and industry depend on chemical reactions

            Living things require chemical reactions

                 1. Respiration

                 2. Photosynthesis

            Chemical reactions are used in technology

            Industry uses chemical reactions to make useful products

The Cell

Objectives;
-Stadents will be aware that prior to our knowledge of cells, people adhered to the idea of spontaneous generation. This widely accepted idea was rejected because of new scientific knowledge.

-Students will be familiar with the scientists who led to the development of the cell theory.

-Students will know and understand the three parts of the cell theory.

-Students will understand the basic structure and functions of the eukaryotic and prokaryotic cell. 

-Students will be able to identify and describe the functions of the organelles inside of a eukaryotic cell.

-Students will differentiate between eukaryoic and a prokaryotic cell.

-Students will explain the differences between a typical animal cell and a typical plant cell.

-Students will understand that multicellular organisms are made up of different types of cells with specialized functions.

-Students will gain practice using the microscope: 1)They will be able to identify its parts and understand the functions of those parts. 2)They will be able to find and focus the specimens present on prepared slides. 3)They will be able to create their own wet-mount slide and focus on the specimen.
