Classification
Name the smallest group of living things
Species
What is something that is present in every living thing? It is usually named the "barrier".
Cell membrane
Is a melted popsicle an example of a physical or chemical change?
Physical
A shaking of the ground caused by a sudden release of energy in Earth's crust.
earthquake
What would happen if the north ends of two magnets were close together?
They repel
What are the two main groups of animals?
Vertebrae and Invertebrae
Explain the main difference between plant/animals and microorganisms.
Microorganisms are unicellular and plant/animals are multicellular.
Name 2 physical properties of ice.
cold, hard,, solid or transparent
The point underground where an earthquake starts.
focus
A complete path that electricity travels through.
closed circuit
What is the difference between endoskeleton and exoskeleton?
Endoskeletons are internal and found in vertebrates that grow with the body. Exoskeletons are external, nonliving, rigid shells typically in invertebrates that require molting for growth.
Why are animal cells round and fluid and plant cells are square and rigid?

insulator
Name the seven levels of scientific classification.
Kingdom, Phylum, Class, Order, Family, Genus, Species
This organelle acts as storage for food, water, or waste, and is much larger in plant cells.
vacuole
color changes, odor changes, gas production (bubbles), formation of a solid precipitate, and energy changes (temperature changes, light emission)
This landform is created when a river meets an ocean and deposits sediment.
delta
These 4 forms of energy can be produced in a circuit.
light, heat, sound and motion
