Goes through the different structural and optical parts of a compound microscope and how a compound microscope functions.

Learn the ins and the outs of microscopy with this reference page. Page explains the various controls that operate a microscope. Also investigates how to make a wet mount.

Zebrafish are used to study heart abnormalities. This lesson plan helps students understand how and why they are important scientific models. Includes handouts.

Using model organisms is very important in scientific research. This lesson plan will help students see why the zebrafish, sea urchin, and fruit fly are commonly used.

An introduction to the world of the microscope. Includes information about the instrument and the subjects you can study through the microscope.

A drawing and measuring activity to give students an appreciation of magnitude in powers of ten, and of microscopes. Students draw themselves and an object life-size, and then examine smaller and smaller pieces of their picture.

Use this series of images depicting the process of mitosis in the early embryo of the fruit fly, Drosophila melanogaster to make a mitosis flipbook. In this stage of Drosophila development, nuclei divide very rapidly without cell...

How do you recognize life on another planet? What tests do scientists use to determine if something is a life form when they are many light years away from being able to observe it directly? Try your hand at interactives to create a...

This is an informative site from Georgia State University. It gives a discussion of the thin lens equation and an illustration of its use in determining the image distance based upon the object distance and the focal length.

This site has numerous pictures of microscopic images. It also has a search engine so you can find specific objects. Images were captured with light microscopes, as well as electron microscopes.

All living things are made of cells. In the human body, these highly efficient units are protected by layer upon layer of defense against icky invaders like the cold virus. This learning module takes a journey into the cell, introducing...

In this advanced simulation, students experiment with changing the ion ratios in solutions and thus the pH. The experiment can be viewed on a macroscopic or microscopic level, or customized.

General information about the ascaris lumbricoides, including: etiology, pathogenesis, epidemiology, general gross description, general microscopic description, and clinical correlation.

"Dr. Murphy is considered one of the world authorities on viruses. He was the first one to look at the Ebola virus 'face-to-face' in the electron microscope." You will get his perspective on this terrible virus in a question and answer...

In this lesson students learn about the circulatory system and how it relates to engineering. Then in a hands-on activity they create a model of blood. Students also act out cholesterol in a blocked artery and look at blood cell in a...

Lenses are precisely shaped pieces of glass that have been developed and used in corrective glasses, telescopes, microscopes, binoculars, and magnifying glasses. They can be convex or concave. Links are provided to a video an a test.

The elephant is a creature of epic proportions- and yet, it owes its enormity to more than 1,000 trillion microscopic cells. And on the epically small end of things, there are likely millions of unicellular species, yet there are very...

This article discusses the life and contributions of Marcello Malpighi.

Introduction to neuron structure, function, and classification. Provides simple diagrams of neurons conducting an impulse and microscope images of nerve cells.
