Content Objective
I can apply my knowledge of the parts and the proper use of microscopes by completing my microscope drawings.
S.IP.07.13 Use tools and equipment (spring scales, stop watches, meter sticks and tapes, models, hand lens, thermometer, models, sieves, microscopes, hot plates, pH meters) appropriate to scientific investigations.
L.OL.07.21 Recognize that all organisms are composed of cells (single cells organisms, multi-cellular organisms).
L.OL.07.22 Explain how cells make up different body tissues, organs, and organ systems.
Language Objective
I can write to present what I learned while looking through microscopes by completing sentence frames.
1.To focus a microscope you first use the ____ then you use the ____.
2.To increase the magnification while using the microscope you first use the ____, then the ____ and sometimes (with the teachers approval) you use the____.
3.If you cannot get enough light through the scope you should check the ___, the ___ or the ___
4.One thing you should never do with the microscope is _______________________.
5.While observing the lower cased letter “e” through the eyepiece of my microscope the “e” appeared to be ________________________________________________________.
6.While observing any object through the eyepiece of my microscope and moving the slide on the stage I observed _____________________________________________.
7.While observing onion cells through a microscope I observed the cells were ______ shaped. I noticed that there were not any _____ because the bulb of the onion grows ____________.
While observing lettuce cells through a microscope I observed the cells were _________________ shaped.
8.I was able to see _________cells and tiny holes called ____ which were surrounded by ___________cells.
9.While observing human cheek cells through a microscope I observed the cells were _____________ shaped. I noticed that there were not any _____ or _____ those can only be found in plant cells.
10.Inside of the cells I was able to see dark spots which were probably ____, which are the _____________________ of the cell and contain the ________ of the cell.
1.To focus a microscope you first use the coarse focus knob then you use the fine focus knob.
2.To increase the magnification while using the microscope you first use the low power objective lens, then the medium power objective lens and sometimes (with the teachers approval) you use the high power objective lens.
3.If you cannot get enough light through the scope you should check the light switch, the diaphragm or the revolving nose piece.
4.One thing you should never do with the microscope is (many different answers).
5.While observing the lower cased letter “e” through the eyepiece of my microscope the “e” appeared to be inverted (upside down and backwards).
6.While observing any object through the eyepiece of my microscope and moving the slide on the stage I observed it appears to move in the opposite direction.
7.While observing onion cells through a microscope I observed the cells were rectangular shaped. I noticed that there were not any chloroplasts because the bulb of the onion grows underground.
8.While observing lettuce cells through a microscope I observed the cells were puzzle piece shaped. I was able to see epidermal cells and tiny holes called stoma (stomate) which were surrounded by guard cells.
9.While observing human cheek cells through a microscope I observed the cells were oval shaped. I noticed that there were not any cell walls or chloroplasts those can only be found in plant cells.
10.Inside of the cells I was able to see dark spots which were probably nuclei (nucleus), which are the control center of the cell and contain the DNA (genetic material) of the cell.
