Physical Change
Changes appearance only
No new substance is formed
Example: Ice melting
300

The "N" in Mrs. Gren. Explain how it is in plants, in humans, and in animals.
Nutrition - Plants make their own food. Humans and animals eat plants or other organims.
400
Bacteria do not have nucleus, they have loops of DNA found in which part of the cell.
What is cytoplasm?
400
Explain chemical change.
Chemical Change
Changes the substance itself
New substance is formed
Example: Wood burning
400
DOUBLE!
Valence electrons of Calcium
What is 2?
500
Give 2 elements with complete valence electrons.
What are He, Ne, Ar, Kr?
500
Seven characteristics of living things
MRS GREN - Movement, respiration, sensitivity, growth, reproduction, excretion, nutrition
500
Compare and contrast: Plant cell and animal cell
Animal Cells: Contains various cell organelles
Plant cell: Presence of cell wall, chloroplast, central vacuole
Both: Types of eukaryotic cells
500
Compare physical and chemical change
Physical Change
Changes appearance only
No new substance is formed
Example: Ice melting
Chemical Change
Changes the substance itself
New substance is formed
Example: Wood burning
Key Difference:
Physical = reversible, no new substance
Chemical = often irreversible, new substance formed
500
