Particle Theory Summative

One of the state is the solid to liquid. For example, in this case if the solid is the ice we can heat the ice to turn it into liquid. When we heat the water particle vibrate and it rolls so it makes the ice to melt.
the second state is the liquid to solid. if we want to turn liquid to solid  we can put the water in to a freezer to turn it to solid and in that case the liquid particles can only vibrate cause it is cold and they are now turning to solid again.


The air particles and the pizza particke bump into each other.

speed report

Speed Report
In science our classes have been working on speed. We had to do a project about speed which is running 30 meters in the field.
Instaneous speed is the speed of an object at a particular moment in time. Instaneous speed is measured by meters per second(m/s). Instaneous speed Is used in
