Virtual Laboratory
The simulation program is based on the Nobel Prize winning Hodgkin-Huxley model for excitation of the squid axon. The program simulates an excised squid axon by applying stimuli or clamps after setting the environment of the axon, changing its properties, and/or adding drugs or toxins. By using the program tools, experiments can be developed that explore a variety of nerve properties, ranging from classical phenomena such as threshold, summation, refractory period, and impulse propagation to mo

Vinegar and baking soda
Vinegar is an acid. An acid has a pH less than 7. When baking soda is added to vinegar, bubbles are produced and gas is released. Fizzing, bubbling, and change in smell are all evidence of a chemical reaction. The amount of gas produced using baking soda as an indicator tells you the relative concentration ...

Using Molecular Weight
A previous tutorial shows how to calculate the molecular weight of a substance from the atomic weights given. On this page, we use the molecular weight to convert between the macroscopic scale (grams of a substance) and the microscopic scale (number of molecules of that substance).

Mechanics Mania
Through ten lessons and numerous activities, students explore the natural universal rules engineers and physicists use to understand how things move and stay still. Together, these rules are called "mechanics." The study of mechanics is a way to improve our understanding of everyday movements, such as how gravity pulls things together, how objects balance, spin and twirl, and how things fly and fall. While studying Newton's three laws of motion, students gain hands-on experience with the concept

Understanding Your Water
Over two class periods, you will be guiding your students through the basics of water treatment -- both tap water treatment and sewage (or wastewater) treatment. To prepare for the lessons on the treatment process, the students will be researching where their drinking water comes from and where their wastewater goes once it goes down the drain for homework. After learning about their local water treatment and traditional tap water and sewage treatment processes, students will watch the NewsHour

Macro to Micro Structures
This program deals with the conceptualization of micro processes and environments. It involves teaching chemistry through macro phenomena, which can be observed, and micro processes, which occur on the molecular level, and can only be imagined. Conceptual change must occur in order for students to understand chemical phenomena. Teaching for conceptual change poses a grea

Vehicle Stopping Distance
If you are traveling 20 mph, how far would your car go before stopping? This video adapted from KET's Street Skills explores the two parts of the stopping process: reaction time, how long it takes your brain to respond, and stopping distance, and the distance traveled between putting on the brake and coming to a stop. Run time 03:51.

1.1.4 Genetic testing of adults
This Unit looks at three different uses of genetic testing: pre-natal diagnosis, childhood testing and adult testing. Such tests provide genetic information in the form of a predictive diagnosis, and as such are described as predictive tests. Pre-natal diagnosis uses techniques such as amniocentesis to test fetuses in the womb. For example, it is commonly offered to women over 35 to test for Down's syndrome. Childhood testing involves testing children for genetic diseases that may not become a p
