MICROSCOPE MANIA Carolyn Hayden Ceci Maguire St. Martha School Louisville, KY
Objectives • Students will identify the basic parts of the microscope and describe the function of each. • Students will demonstrate the proper procedure for viewing a prepared slide at different powers of magnification. • Students will demonstrate the proper technique for making a wet mount slide and viewing it at different powers of magnification. • Students will contrast low power and high power magnification. • Students will discover the similarities and differences between animal and plant cells.
Essential Questions • How are cells important to the structure and function of living things? • How do microscopes contribute to our knowledge about living things?
PRELIMINARY ACTIVITIES • Parts of a microscope. • General procedures.
Station 1:MYSTERY PICTURES • Identify 24 mystery pictures – close-up, magnified views of common objects.
Station 2:MAKE IT SIMPLE • Create a simple lens to view the letter “e”. Compare how the size of the water drop affects the magnification and compare the magnification to that of a hand lens.
Station 3:SELECT-A-SLIDE • View prepared slides under different powers of magnification and learn how to carefully record observations. Describe the differences between low and high power.
Station 4:ANIMAL CELLS • Make a wet mount slide of human cheek cells and view it under different powers of magnification. Identify the major organelles of animal cells: nucleus, cell membrane, and cytoplasm.
Station 5:PLANT CELLS • Make wet mount slide of Elodea leaves and view it under different powers of magnification. Identify the major organelles of plant cells: nucleus, cytoplasm, cell wall, and chloroplasts. Differentiate between animal and plant cells after completing both stations 4 and 5.
Station 6:SCOPE BASICS • Label the parts of the microscope in the shortest amount of time in Parts and Pieces. Review basic vocabulary by matching all cards correctly in the shortest time in the Vocab Challenge. Play two review games at the SMARTBoard.
