Laboratory Equipment And Experiments For Determinations Of Density, L. Begeman
Laboratory Equipment And Experiments For Determinations Of Density, L. Begeman
Science Bulletin
Laboratory experiments in Density require the following apparatus: beam balances, meter sticks, graduates, calipers, tumblers, test tubes, and hydrometers. There should be as many of each as possible· in order to reduce the amount of group work. The objects for study should include pieces of lead, zinc, marble, paraffin, beeswax, glass stoppers, shot, gasoline and solutions of salts such as blue vitriol.
Hydrostatics, L. Begeman
Hydrostatics, L. Begeman
Science Bulletin
The teacher may introduce this subject to the class by reference to the meaning of "pressure" as used in mechanics. Explain to them that the gauge pressure in a steam boiler or auto tire refers to the number of pounds pressure on each square inch of inner surface. Sometimes a problem will make it clear.
Something From Nothing, W. H. Kadesch
Something From Nothing, W. H. Kadesch
Science Bulletin
Matter made while you wait-hydrogen, helium, oxygen, iron or what will you have? No, it has not quite come to this! But the time-honored law of conservation which states that matter is neither destructible nor creatable is no longer accepted as unquestionably and universally true.
The Beginning Course In High School Physics, L. Begeman
The Beginning Course In High School Physics, L. Begeman
Science Bulletin
All authorities on the teaching of physics are agreed that the beginning work of a class in high school physics should be distinctly concrete in nature. It should consist of such subject matter as will readily connect up with the acquired concepts of the student. It is best not to begin with the unfamiliar, abstruse concepts of force, motion and acceleration usually placed first in the high school text.
