PHYSICS AND PHYSICISTS

 

 

  Science and engineering fairs, hosted by schools worldwide, offer students the opportunity to experience the practices of science and engineering for themselves

 

  Incorporate physics games and activities into your science curriculum with this collection of classroom supplements. The chapter includes fun and engaging games/activities that explore a variety of fundamental physics concepts, including: Centripetal force Mechanical advantage Momentum Thermal conductivity Inertia Air pressure Energy conservation Gravity Bernoulli's and Pascal's principles Parallax and stellar parallax Prisms Electricity, conductors and insulators

  1. Saturn can float on water like ice Saturn is a huge planet, the second largest among the eight planets in the solar system. Saturn has a density of less than that of water, around 0.7 g/cc, whereas the density of water is 1 g/cc. According to the theories of flotation, a substance which is less density than liquid floats in that liquid. So, Saturn might literally float on water. 2. Water can boil and freeze at the same temperature Water may boil or freeze at the same temperature. The temperature and the value of the pressure correspond to a point known as a triple point. At this point, the three phases, liquid, ice and water vapor coexist which means that the water can boil and freeze at the same temperature. 3. The sun doesn’t change color during sunset The sun doesn’t change color during sunset, this is because the wavelengths of the sun react with the difference in the atmosphere.
