GREAT JOB LAST WEEK EVERYONE.
CONTINUING WITH ENERGY,
WE WILL START TALKING ABOUT ELECTRICITY.
Start thinking about our good old friends the small electrons.

and are present anywhere we find matter.
SCIENCE 6th GRADE.

THERE WILL BE A QUIZ EVERY WEEK ON WEDNESDAYS.
IT WILL COVER THE MATERIAL THAT WE SAW DURING THE WEEK.
We will continue talking about waves and other forms of radiant energy.
Waves move away from the source of origin. They have speed, amplitude and frequency.
Waves display diFferent behaviour when they interact with matter.
Waves bounce off.
Waves are absorbed.
Waves pass through.
We will discuss WAVES. Light and sound.
We will observe how light is reflected and talk about some other properties of waves.
