Earth and Space
How long does it take Earth to rotate on it's axis?
24 hours
2 Part Question:
What is a force?
When labeling forces in a model, this symbol can used to represent forces.
A force is a push or pull on an object.
Arrows can be used to label forces in a model.
Name the 7 steps of the Engineering Design Process.
1. Investigate 2. Brainstorm 3. Design 4. Build
5. Test 6. Modify 7. Reflect
Name the 3 basic states of matter.
Name one word to define how one state of matter changes into another. For example, what is it called when a solid turns to liquid or liquid turns to gas.
Solid, Liquid, and Gas
Condensation, Evaporation, Vapor, Melting, Freezing, etc.
What word is added to a cloud to identify it as a storm cloud?
What percentage of the water on Earth is available, fresh drinking water?
1%
Balanced forces are equal and opposite of each other and create stability. Give an example of how an unbalanced force can create change in a motion. Explain where the change from balanced to unbalanced happens in this action/example.
For example: A board is laying across a stream as a bridge. When a person walks on it, it dips down in the middle, applying a force that makes the bridge unbalanced and move from a straight board to a bent board.
An unbalanced force creates a change in motion/movement. Examples can be but are not limited to: tug of war, seesaw, breaks on a car, kicking a ball, etc.
Oh, No! You just bought a home in Slide City. What practical, scientific solution can you design to help protect your home? Think about what you've seen, when traveling along rocky hillsides.
Rock Net
Human Pick Up
Retaining walls
Define Property. We've used this word in many situations. Properties of clouds, magnets, rocks, acids, foods, etc.
A property is a characteristic that describes an object. Objects have multiple properties.
What is a natural disaster? List 3 examples of natural disasters.
Natural disasters are natural processes in the Earth's atmosphere that cause extreme weather conditions.
Examples: Hurricanes, floods, landslides, tornados, wild fires, etc.
Draw a diagram of the sun in the horizon of the sky at Winter and Summer at noon (midday).
Winter sun is low in the horizon, Summer sun is high in the horizon
What word is use when an object hits another object, a force is applied and movement is created from the collision.
Energy Transfer
Why is it important for engineers to "reflect" after a project is finished?
It's important to discuss what went right and what could use improvement, in any project. This is how scientists and engineers learn from each other and share important knowledge to the world population.
Everything is made of matter, sometimes in tiny pieces too small to be seen. What do we call these tiny pieces?
Particles
(Half credit for Molecules)
What is climate?
Climate is the year to year patterns in the earth's atmosphere over a large area.
Name the 4 spheres and what each one consists of.
Hydrosphere=water on earth and water cycle
Biosphere=all living things, plants and animals
Atmosphere=the air we breathe and our protection
Geosphere=the land, dirt, rocks, mountains, etc.
Draw a model of an electrical circuit using these materials:
Battery
Light Bulb
Alligator clips or wire

What is a constraint or limitation in an Engineering Challenge?
These are the rules we need to follow. Things that limit our build. Examples may be size, weight, budget, materials, etc.
Define a chemical reaction.
When two or more different substances are mixed, a new substance with different properties is formed
Give an example of a type of weather.
Give an example of a type of climate.
Weather: rain, clouds, snow, heat, wind
Climate: temperate, desert, mild, polar, tropical
What do we call the big sheets of crust that we live on? These large areas of crust can sometimes move, creating earthquakes and volcanoes. What do we call the pattern of volcano locations on our globe?
Plates
Ring of Fire
Why is gravity so important to human life on Earth?
100 Bonus
What type of energy is being used with the hills in a roller coaster?
So many examples of things floating
The crust would not be solid enough to grow food or build on
Water cycle
Bonus: Height or Gravitational Energy
What is a prototype?
Model, something you're building
Name 2 properties of an acid.
Sour, Reactive, Burns, Preserves
What is the name of a scientist who studies weather?
Meteorologist
