In this demo, a polyethylene strip is charged by rubbing with wool. The strip is then used to test what happens to the flow of charge when the strip is placed in contact with a conductor (iron nail) and the materials are then moved towards a neutral object. An... read moreCategories: Teacher Demonstration
Turning water into wine and then into beer and finally milk is an extremely versatile chemistry demonstration. It can be used to introduce or reinforce several important concepts in chemistry including evidence for chemical change and types of chemical reactions... read moreCategories: Lab/Student Activity
In this demo, two circuits are constructed to enable comparison of the brightness of a light bulb placed in a circuit with one cell and the brightness of the same light bulb in a circuit with three cells connected in series. In Next Steps the potential differences of... read moreCategories: Teacher Demonstration
This demo illustrates the presence of atmospheric air pressure and shows how the force that it exerts is greater than the force of gravity in some situations. read moreCategories: Lab/Student Activity
In this demo, two circuits are constructed to enable comparison of the brightness of a light bulb placed in a circuit with one cell and the brightness of the same light bulb in a circuit with three cells connected in parallel. In Next Steps the potential differences... read moreCategories: Lab/Student Activity, Teacher Demonstration
In this demo, a polyethylene strip is charged by rubbing with wool. The charged strip is then used to charge a neutral object, a pith ball, by contact. This demo can be done as a student activity. read moreCategories: Lab/Student Activity
Since the distances to the stars cannot be measured directly, astronomers use a variety of techniques including triangulation and parallax, comparison of absolute and apparent magnitude, and Cepheid variables. Triangulation is an indirect method of measuring the... read moreCategories: Lab/Student Activity, Teacher Demonstration
Cells require a constant supply of glucose and oxygen to produce energy. Cellular respiration occurs in the mitochondria of a cell. As a result of this process, large quantities of waste carbon dioxide must be expelled from the cell. All materials involved in this... read moreCategories: Teacher Demonstration
This demonstration is a great way for students to model the stages of mitosis. Images of the different stages in textbooks are static snapshots and many students have difficulty grasping the idea that mitosis happens as part of a continuous cycle. read moreCategories: Teacher Demonstration
This is a simple, yet extremely effective model of human lungs. Students are able visualize how the lungs, thoracic cavity and diaphragm work together to facilitate inhalation and exhalation. This model can be prepared before class to be used as a demonstration and... read more
