THANK YOU! I am very pleased with the quiz grades today. We had several 100's. Today we started reviewing for Conduction, Convection, and Radiation; some students are still getting confused.

Conduction- the transfer of heat by touch
Convection- the transfer of heat by currents (through liquid or gas)
Radiation- the transfer of heat by waves (like fire or the sun)

There will be a worksheet Wednesday night for homework to review. 

Physical and Chemical change were major topics missed on the practice EOG.

A Chemical change is when you change the substance completely. Something new is formed after the chemical reaction. Examples: Apple rotting, wood burning, nail rusting. You can see that the substance looks different, there may be a new color or bad smell.

A Physical Change is still the same substance but it has been altered a little. Example: slicing an apple, cutting wood, or painting over a nail.

I have asked to students to remember the key words in a chemical reaction that may be on the EOG answer choices. Words like rotting, rusting, burning...those are key indicators the answer is a chemical reaction.
