Separating and  Controlling Variables. September 26/17 * when carrying out and experiment the scientists have very in mind: controls, dependent variables and independent variables. *  What is a variable? in an experiment a variable indicates an amount or a condition that can change. * Dependent variable: it is a variable that we observe and measure. * Independent variable: it is a variable that we can control. * Control: provides a basis of comparison in the experiment. 1.procedure page 844  point 1-6 *The salt is independent variable. *Temperature of water is the dependent variable. *The volumen of water is control. 2.Ten grams of sugar dissolves more quickly in a liter of pure, hot, tap water than in a liter of  pure, cold, tap water.  List the controls, the indepent variable an the dependent variable. *the velocity of dissolves sugar in the water is the dependent variable. *the temperature and sugar is the independent variable. *the control is the volumen o

COMPARING AND CONTRASTING. We find different states of matter:  Solid  Liquid  Gaseous  And these can be transformed back in the  others states.  Example:  Liquid - Solid  Solid - Liquid  Liquid - Gaseous  Gaseous - Liquid  If we compare Helium- Neon laser, bronze,  cloudy ice cube, and ginger ale, we can  observe different types of solutions with  different states of matter. Of these  elements we can obtain:  Helium/ gaseous - neon laser/ liquid  Bronze/ solid - Cloudy  ice cube/ solid  Ginger ale/ liquid.

the nuclear atom

Imagen
  THE NUCLEAR ATOM ATOMIC MODEL  is a representation of a atom ALPHA PARTICLE Consist of two protons and two neutrons bound together into a particle identical to a helium nucleus. ELECTRON Is a negatively charged. NUCLEUS Is the small dense región consisting of proton and neutrón at the center of an atom. PROTON A positively charged, elementary particle that is a fundamental constituent of all atomic nucleus. NEUTRON An elemetary particle having no charge, mass slightly greater than that of a proton and spin of ½ : a constituent of the nucleus of all atoms except those of hydrogen. Symbol N.
