General Science/Biology Files for the Mac/PC

 

The programs are FREE for distribution and the author welcomes suggestions for repairs and improvements.
These two exercises make use of the applet version of ImageJ. This version should shortly be running in a separate "ImageJ" window. The download will take a few seconds with an Ethernet connection or about two minutes using a 28.8 modem. Quit ImageJ by clicking on the "ImageJ" window's close button. When you go to the Windows version of one of the exercises below the ImageJ application will remain running in the background.

(NOTE: ImageJ opens up without any problems using either Netscape of Internet Explorer on Windows. Internet Explorer 4.5 and above works fine on the Macintosh, but there is no Netscape support at this time on the Macintosh. For further information on this go to Pepsan and Associates Link) - Java on the Macintosh. If you wish to download a version of ImageJ to your computer's hard drive so you can evaluate your own images a download can be obtained at the following site.

Problems and Comments on ImageJ's performance. An Adobe file that you might want to look at and/or print out.

Modifying ImageJ This link will take you to a WEB page with instructions on how to modify ImageJ to present your own files. There is NO programming involved.

In the exercises categories that are described below you will have three windows open at a time (the WEB page, ImageJ and at least one image) so you may want to go to your control panel on your computer and change the monitor size so that you can readily move between the different windows.

You may want to printout the two exercises shown below so that students can enter the information in the Results Sheet.


CELLULAR

These exercises are designed to serve as an introduction to measurement in microscopy and cellular structure. This is followed by plant and animal cellular structure and physiology. Comparisons are made between cellular light microscopic views and those taken with the scanning electron microscope. Teacher/students are encouraged to take their own light microscope images and compare them with the results from these exercises.

 

ENVIRONMENTAL

An example of the plight of the Aral Sea using an ImageJ application technique known as density slicing. This technique and others shown in EcoAnalysis can be used on Landsat images that can be found on the WEB. It is also possible to use the graphing technique employed in EcoAnalysis to evaluate the results of student environmental projects.

 

BIOLOGY

In this general category we focus on Lyme Disease and its transmission using light microscopy and scanning electron microscopy images. Other exercises look at insect structure and the various measurement techniques that are available to make comparisons. An introductory exercise called Animal Hands makes also makes its WEB debut. Lastly, there are a couple of exercises on Biotechnology.

 

HUMAN PHYSIOLOGY

A bone density exercise takes a look at the problem of osteoporosis. Normal and abnormal bone structure is compared and the results can be graphed. The skin cancer exercise focuses on the recognition of a skin melanoma as well as examining tissue samples of the skin cancer under the microscope.

 

IMAGE PROCESSING SKILLS

A series of introductory exercises involving the mathematical analysis of some common objects. The skills acquired by student s here can be used to investigate the flora and fauna in the world around them.
