Real Life Environmental Science Applications

This kit teaches the student how to determine the evolutionary closeness of organisms based on antigen-antibody blood analysis.
Immunological comparisions (homology) are perhaps the most fascinating of the five methods by which organisms are classified.

Apply Multiple Senses In The Observation Process

Students Examine Their Own Blood To Identify Components

This activity encourages students to use deductive reasoning when analyzing unknowns.

Explore the role Of respiratory system in regulation of blood gases.

Ideal Size For Student Demos

Help your students gain an awareness of the significance water pollution plays in the environment. These simple qualitative tests of natural and treated water produce reliable results through vivid color changes.

Eliminate the need for glassware and provide a semi-micro environment for conducting many experiments with this clear tray about the size of an index card. You can use Chemplates instead of test tubes, as a demonstration vessel for your overhead projector, for individual student experiments, or even as a gas generator or water reservoir. Twelve large numbered cavities are molded into the high-impact plastic. In addition, each plate has a jumbo-sized cavity and a snap-off measuring spatula. Gas collecting tubes, available separately, fit the Chemplate caps. Package of ten.

Two Activities Introduce Your Students to the Periodic Table of Elements

Investigate all five senses in one kit.

Model The Effects Of Antibiotics On Disease Causing Bacteria During Infection

Demonstrate the Costs and Benefits of Biofuels

This kit provides a series of “hands-on” activities that allow students to use key Earth Science concepts by conducting a mineral exploration that simulates real-life economic, societal, and issue oriented problems.

A basic introduction to DNA.

Nine level conductivity meter shows the relative conductivity/resistance of liquids and solids. As the conductivity of the tested material increases, the number of glowing red LEDs will increase to a maximum of 8, which indicates a very good conductor. There will be zero glowing red LEDs if the material has a very low electrical conductivity (is a good insulator).
