Unit One - What is Life?
Science - an organized way of collecting and analyzing evidence about the natural world.
Science provides explanations for events in the natural world, an understanding of patterns in nature, and
predictions about natural events.
Whale Research
Uncertainty in Science
Why are hypotheses so important to controlled experiments?
Inference or observation?
Amin has a grey microscope with three objective lenses.
Morgan does not like her microscope.
Nathan used a dropper to make a wet mount slide.
Two protozoans, of the same size, converge and bump into each other and then swim away.
The two protozoans were fighting.
The two protozoans were after the same food.
The long, snakelike creature that Zaki saw must be a worm of some type.
Controlled Experiment
Living things are based on a universal genetic code
Living things grow and develop
Living things respond to their environment
Living things reproduce
Living things maintain a stable internal environment
Living things obtain and use material and energy
Living things are made up of cells.
Living things evolve

Characteristics of Kingdoms
The unusual Protists:This group does not have a common ancestor
so quotations are used to show that this is not a true clade
