1. Remind students of the different substances they have worked with and explain that these substances are all made of atoms and molecules. Remind students that the different materials they have ...
A team of physicists and engineers at the University of Colorado Boulder has discovered a new way to measure the orientation ...
Bohr turned to Planck's quantum theory to explain the stability of most atoms. He found that the ratio of energy in electrons and the frequency of their orbits around the nucleus was equal to ...
Space-time may hide a bizarre new kind of black hole that causes Einstein’s theory of gravity to fail – and could solve the ...
Students will be able to explain that the parts of an object can be rearranged to create a new object. Students will also get a sense of the number of different objects that can be created from a ...
Phase transitions, shifts between different states of matter, are widely explored physical phenomena. So far, these ...
Half-life describes the interval of time during which half of the original atoms decay. Give each group a shoe box and one set (80) of either pennies, dice, or sugar cubes. Explain that the ...
Two presenters use animations to show how protons, neutrons and electrons make up atoms. They explain the relative masses, sizes, locations and charges of these subatomic particles. Introduce ...
