The article on Elodea appeared in the NSTA publication of The Science Teacher. The article on Microscopy was in the publication Microscopy Today.
MOS A Link to a workshop conducted at the Museum of Science on Imaging and its use in Biotechnology.
Boning-Up A Various exercises using skeletal bones for sex/height identification or for specific species identification.
SEM Images A collection of scanning
electron images and possible exercises produced using the school's SEM.
Virtual SEM A series of pages where you are able to vary the
magnification of a number of SEM images that have been taken over the last few
years.
Access Excellence A Microscopy Resources. Featuring Light and SEM images that can be used for instructional purposes. This page is linked to the Resource Center of Academic Excellence.
GeoSEM A collection of volcanic images produced from samples
collected on different school field trips or dusty shelves in the Science Building.
Internet
Imaging: This link connects
you to a page that automatically brings up ImageJ.
ImageJ is a JAVA image processing program that is based on NIH Image. There
are a number of student exercises that can be run using ImageJ. ImageJ as a
download application or an online applet can be obtained at http://rsb.info.nih.gov/ij/
The author, Wayne Rasband (wayne@codon.nih.gov), is at the Research Services
Branch, National Institute of Mental Health, Bethesda, Maryland, USA. This is
a "work in progress".
Get those Images A collection of inexpensive
ways in which to obtain images for biology and general science.
The Honeybee An introduction
to the structure and physiology of this insect using light and scanning electron
microscopy. These pages are complete with links to other information sites.
Colorize
- A number of SEM images have been falsely colored to - show detail better,
look pretty?? - you decide. They are all in three compressed JPEG forms. The
original image with its micron bar, colorized image and then colorized with
micron bar.
Ugly Bug Contest
A contest that is open to all New Hampshire elementary schools. Further information
and rules can be found at this site.
Center
for Image Processing for Educators
The following two biology exercises are provided by CIPE.
The exercises can be done online using ImageJ.
Animal Hands: (Students use image
processing to examine x-rays of hands, wings, hooves and flippers to compare
their structures and functions. Image processing allows them to change the way
the information contained in the x-rays is displayed. They use a variety of
techniques to study the detail in the images. ) Brain's
Blood Supply: (t introduces students to basic image enhancement tools such
as false colorization, inversion of pixel values and digital filters to sharpen,
shadow and find edges. In the second part of the lesson, students measure the
diameter of the aorta and arteries in the neck, then calculate the radius, cross-sectional
area and resistance for each vessel. After analyzing the data, they infer relationships
between vessel size and relative blood flow. )
Teach
A series of training exercises for Teachers in Image Processing as well as instructions on how to modify ImageJ for your own needs. Includes WEB based exercises that can be used in Middle School/High School General
Science/Biology
Angles A Link page that was developed by elementary school teachers to instruct their students on angles. Includes many local images of buildings.
Loggerhead
Sea Turtle Examination
of a Loggerhead Sea Turtle skull that was donated to the school back in the
19th. century.
Image Listing A PDF file of Light Microscope and SEM images compiled over the last few years. (Free for educational use.)
Snowflakes Snowflakes are captured on a cold glass slide and then coated with a clear acrylic spray. The snowflake melts leaving the acrylic impression. These impressions are then examined under reflectance light microscopy and SEM.
QTVR (Quicktime Virtual Memory) A method of stitching together images into a panorama and then manipulating your way through the image and interconnecting with other sites/images on the WEB. The first example of this is a combination of Light microscope and SEM images of diatoms.
A combination of SEM images with additional panoramic images of the Academy Building and acquarium in the Science Building.
WOWBugs:(Melittobia digitata) Various SEM QTVR panoramas of this parasitic wasp
Tour A panoramic tour of one of the biology classroom/laboratories in the new Science Building. (Also includes a general layout of that wing of the building.)
