How do you show things that you have to proof ,that are microscopic?
• We can provide a model that shows the magnification of the actual thing.

when temperature rises in water, the molecules are activated and energy is pass to one particle to another therefore it moves faster. liquid's molecules are wide apart but not as much as in gases. The more energy they'll gain the more it will start changing into gases. This is how the process of evaporation is. The water would then change into Gas state-Water Vapour

Movement of Particle...

Fill a petri dish with BB's. Tape the cover on. Place on top of a overhead and shake bacand forth. There will be little motion of the particles. this shows the motion of particles in a solid. For young children have them slowly move their fingers back and forth. This will give them the idea of the motion of solid particles









Fill a petri dis about half full with BB's. Tape the cover on and place on top of a overhead. shake the container back and forth. The particle willl move much faster than the solid as they are farther apart. For young children have them wave their hands quickly back and forth. This will give them the idea of the motion of liquid particles







place a few BB's in a petri dish Tape the cover on and place on top of a overhead. shake the container back and forth as fast as you can. The particle willl move much faster than the solid or liquid as they are farther apart. For young children have them wave their hands quickly back and forth as fast as they can move them. This will give them the idea of the motion of gas particles

    • We can provide a model that shows the magnification of the actual thing.As a model it is useful because it appears to explain many phenomena but it has limitations.'
    this was copywrited -.-

  2. Good progress! Now what your are describing is correct, but it is only a MODEL the reproduces the phenomenon, but it does not PROVE the theory. In order to prove it, you will need to provide DIRECT EVIDENCE. Your model will come in handy to explain it at your project presentation.

  3. Comment to what Amy and gang said...
    There are a range of sizes of particles - atoms and molecules are sub-microscopic (too small to be seen by microscope), but microscopic particles are visible under the optical microscope!
