What is the Engineering Design Process?
Steps engineers take when solving or fixing a problem

Explain a planets relationship to the universe
Planets make up solar systems which are found within the galaxies which then make up the universe
Planet --> Solar System --> Galaxy --> Universe

5 things ALL organisms need to be considered alive
Made of cells
Uses energy
Responds to the surroundings
Grows and develops
Ability to Reproduce
100
Describe how a cell makes up a human organism
Cells -->Tissues --> Organs --> Organ Systems --> Organism (Human)

What is density?
How heavy and tightly packed the molecules are in an object
200
When thinking of a design solution, engineers must think about the criteria and constraints of their idea.
What are criteria and constraints?
Criteria: Requirements of design
Constraints: Limitations placed on design
200
What is gravity?
Force of attraction between objects
200
What does the Law of Superposition tell us about the ages of the rock layers and fossils in sedimentary rocks?
Older rocks and fossils are found in lower layers while younger rocks and fossils are found in higher layers
Layers on top are more recent than layers below
200
What are the 3 differences between plant and animal cells?
Plant cells need a cell wall for structure and support, a large vacuole to hold water and chloroplasts to capture sunlight so they can perform photosynthesis in order to make their own food.

What two body systems are working together when your lungs take in oxygen and transport it to parts of your body?
Respiratory and Circulatory

Describe the relative density of these liquids
The blue liquid is the LEAST dense
The red liquid is the MOST dense
The yellow liquid is MORE dense than the blue but LESS dense than the red
200
Define amplitude; frequency and wavelength
Amplitude: Height of wave; measures energy of wave
Frequency: Number of waves/number of times wave cycles
Wavelength: Distance between waves

List and describe 1 material that could be used to make this lamp.
Include what part of the lamp and why.
Glass: Lightbulb: Transparent
Metal: Plug: Conductor
Rubber: Cord: Insulator
Plastic: Base/Switch: Flexible; strong; Insulator

How does mass and distance impact gravitational force?
More mass = more gravity/stronger
Less Mass = less gravity/weaker
Closer together/less distance = stronger gravity
Further apart/more distance = weaker gravity
300
What is the continental drift theory?
Identify one piece of evidence that scientists have that support this theory.
The continental drift theory suggests that the continents were once joined together and have moved apart over time.
Evidence:
1 – The continents look like they would fit together like a puzzle
2 – Fossils of the same ancient organisms have been found on different continents
3. Rock patterns are the same across continents
300
What is the difference between a multicellular and unicellular organism?
A unicellular organism - an organism that has just ONE cell. That cell performs ALL functions necessary for that organism.
A multicellular organism has many specialized cells that perform specific functions for the organism.

Your body systems work together to maintain a stable internal environment known as...
Homeostasis
300
How do we calculate the density of an object?
What would the density be of an object that has a mass of 40g and a volume of 4cm3?
Mass divided by volume
10g/cm3
300
Why can astronauts not hear anything on the Moon?
Sound is a mechanical wave; nothing in space to carry sound energy
400
What happens during the research stage of the engineering design process? How is it related to design?
Research: Gather information to develop ideas
Design: Take those ideas and make a drawing
400
Explain how moon phases occur
When the moon revolves around the Earth and the Earth revolves around the sun; different amounts of sunlight are being reflected - the amount of light being reflected off the moon represents the moon phases
400
Remains/traces of past organisms that give evidence of existence and diversity of organisms throughout the history of Earth.
Fossils
400
Cells have organelles that allow them to carry out functions of life. Identify and describe the function of the 4 key organelles.
Nucleus: Controls the cell
Cell Membrane: Protects the cell f
Mitochondria: Creates energy
Vacuole: Stores important substances
400
What is a pure substance?
Substance that cannot be separated into simpler substances
500
Why is providing feedback and important step of the Engineering Design Process?
Allows for improvements
500
What is the difference between a solar and a lunar eclipse?
Solar Eclipse: Moon moves between Sun and Earth blocking sunlight from reaching Earth
Lunar Eclipse: Earth moves between Moon and Sun; blocking sunlight from the moon
500
These are body parts of very different species/organisms that are SIMILAR in structure and/or location but DIFFERENT in function.
Homologous Structures
500
What is a mixture?
A mixture is something that can be separated into simpler substances
