Lesson Plans
Strand 7.3: STRUCTURE AND FUNCTION OF LIFE
Living things are made of smaller structures, which function to meet the needs of survival. The basic structural unit of all living things is the cell. Parts of a cell work together to function as a system. Cells work together and form tissues, organs, and organ systems. Organ systems interact to meet the needs of the organism.
Standard 7.3.1
Plan and carry out an investigation that provides evidence that the basic
structures of living things are cells. Emphasize that cells can form single-celled or multicellular organisms and that multicellular organisms are made of different types of cells. (LS1.A)
-
Cell Day
Students will collect samples and bring them to school to look at underneath the microscope. They will keep a journal of their observations and drawings and summarize their findings.
-
Observing Single Celled Organisms
Student will observe and describe cellular structures and functions of
pond microorganisms. They will identify cell parts and determine how the organisms
carry out the functions of life such as extracting energy from food, removing
waste, and producing their own food.
-
Osmosis In Cells
Students will read about osmosis and how it affects plant and animal cells and study pictures that show the effects of osmosis on plant and animal cells. Then they will answer questions and label diagrams to show how osmosis will affect plant and animal cells in different salinities.
-
Plant and Animals Cells
This is a commonly done activity to teach microscope skills and the differences between plant and animal cells.
-
