With stiff 'arms' radiating in all directions, these microscopic organisms look like sea urchins

Mixed genera. Also known as scuds, amphipods are freshwater crustaceans.

Drosophila melanogaster, the common fruit fly, is widely used in genetic studies. They express a number of mutations such as eye, wing, and body mutations.

A Rate Law Experiment

Smear of isolated cells from buccal cavity of a normal human male. Barr bodies are absent.

Learn about the nutrients in food including proteins, carbohydrates, and lipids.

What Does A Buffer Do?

This is the most widely studied Turbellarian, a free-living flatworm commonly used in science fair projects.

Simulate ocean acidification by introducing carbon dioxide into water and measuring pH over time.

Ideal for Teaching the Value of Fresh Water

Use Raoult's Law to Determine the Effect of Temperature on Vapor Pressure

Stoichiometry for AP Chemistry

Characterized by a lack of rigid cellulosic walls, instead these organisms have pellicles made of protein. They store paramylon instead of starch.

Determine the Unknown!

Distinguish between endospores and the vegetative structures of bacterial cells. The endospores will stain green against a pink background. Includes spore staining solution, safranin O solution, and instructions.
Shelf life is 3 years.
