Science Stage 5 Review Flashcards

Flashcards covering various science topics from the provided text, including flower anatomy, water properties, solutions, the water cycle, pollution, forces, seed germination, magnets, space objects, sound, and animal adaptations.

Anther

The part of the flower where pollen is produced.

Filament

Supports the anther.

Ovary

Contains the ovules; develops into fruit.

Sepal

Protects the flower bud.

Stigma

The receptive surface for pollen.

Style

Connects the stigma to the ovary.

Pollination

The process where pollen is transferred to the stigma.

Fertilization

The stage after pollination where the sperm cell fuses with the egg cell.

Fruit Production

The development of the ovary after fertilization.

Germination

The process where a seed sprouts and begins to grow.

Seed Production

The formation of seeds after fertilization.

Boiling Point

The temperature at which a liquid turns into a gas.

Freezing Point

The temperature at which a liquid turns into a solid.

Water Vapor

The gaseous state of water.

Control Variable

A variable that is kept constant during an experiment.

Dissolve

The process where a solid mixes completely with a liquid.

Solution

A homogenous mixture of a solute dissolved in a solvent.

Solute

A substance that dissolves in a solvent.

Water Cycle

The continuous movement of water on, above, and below the surface of the Earth.

Pollution

Harmful substances introduced into the environment.

Friction

A force that resists motion when two surfaces rub together.

Air Resistance

A force exerted by the air.

Water Resistance

A force exerted by water.

Dependent Variable

The variable being measured or tested in an experiment.

Fair Test

A test where only one variable is changed at a time to ensure accurate results.

Magnetic Material

A material that is attracted to a magnet.

Man-made Object (in orbit)

An object made by humans that orbits the Earth.

Natural Object (in orbit)

A natural object that orbits a planet; Earth's is the Moon.

Volume

The loudness of a sound.

Pitch

The highness or lowness of a sound.

Adaptations

Characteristics that enable an organism to survive in its environment.
