200

What is an "element?"  

Substance that consists on only one type of atom

Name one type of biodiversity and provide one advantage.

Genetic engineering

Cloning

Artificial selection

400

Punnett Square: Ff x Ff

50%

500

Part 1: Prokaryotic cell example

Part 2: Explain one difference between a prokaryotic cell and a eukaryotic cell

Bacteria

No cell nucleus

Flagella 

Genetic material scattered throughout the cell

Lacks organelles

Science!

100

Define "hypothesis." 

Educated guess

200

Define "Science."  

Making observations about the natural world

300

Define or describe a scientific theory.

Attempts to explain "how or why"

Does not go on to become a scientific law

400

Explain "scientific law" and provide an example.

Observation about the natural world that holds true under certain conditions

Universal gravitation

Conservation of mass

Conservation of energy

500

Explain two advantages of a formal scientific experiment using the scientific method.

Cause/effect relationships

Support ( or non-support) of a hypothesis

Easily replicated/repeated

Variables more easily controlled

Forces

100

Name two "non-contact" forces.

Gravity, Magnetism, Electricity

200

Name two contact forces.

Normal, Applied, Friction

300

Inertia

400

Explain Newton's 3rd Law of Motion and provide an example.

Action/Reaction: Answers will vary.

500

Part 1: Explain the difference between mass and weight. Part 2: If an object weighs 60 lbs on Earth, what would its approximate weight be on the Moon? 

Weight differs as it's affected by the force of gravity.

Magnetism and Electricity

100

400

Explain how auroras are created.

Charged particles from solar flares interact with Earth's magnetic field.

500

How are series and parallel circuits different?  

Series: All portions of the circuit turn turn on/off at the same time.

Parallel: Parts of the circuit can be activated separately.
