What is weather?
the physical conditions of the atmosphere at a specific time and place
Who is teaching us now?

What are atoms made of? What are the charges?
Protons = positively charged
Neutrons = no charge
Electrons = negative charge
What is displacement?

What is the difference from a Cation and a Anion?
Cation - positive charge, fewer electrons than protons (lose electrons)
Anions - negative charge, more electrons than protons (gain electrons)
What is a scalar quantity? What is a vector quantity?
Scalar quantity - describes the size of a measurement or the amount being counted (doesn't include direction).
Vector quantity - has both magnitude and direction.
What are invasive species also considered?
Alien species - a species that can take over the habitat of a native species
What is climate change?
a long-term shift in the average weather conditions of a region, typically over decades or longer.
Who made a guest appearance?
Mrs.Vance or Mr.Marshall
