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
