Energy & Waves
This type of energy is the energy an object has because of its motion.
Kinetic Energy
This process allows plants to produce their own food by using carbon dioxide, water, and sunlight.
Photosynthesis
This natural process wears down rocks and carries away small pieces over time.
Erosion
Resources like coal, oil, and natural gas that take millions of years to form and cannot be replaced quickly are called this.
Nonrenewable resources
This important part of the engineering design process allows engineers to identify and fix problems before creating the final version of a product.
Testing/experimenting
A roller coaster has more of this type of energy at the top of a hill compared to at the bottom.
Potential Energy
The role of these organisms is to break down dead matter and return nutrients to the soil.
Decomposers
Name the four layers of the Earth in order from the outermost to the innermost.
The crust, mantle, outer core, and inner core
Removing too many trees from a forest can cause this environmental problem.
Deforestation
Name two examples of how engineers have improved technology to make life easier.
Examples can vary
The distance between two peaks of a wave is called this.
Wavelength
In an ecosystem, when organisms are affected by changes like temperature or food availability, they may use this to help them survive and reproduce. What are these changes called?
Adaptations
The Earth’s spinning on its axis causes this daily cycle.
Day and night
The three Rs that help reduce waste and conserve resources are these.
Reduce, reuse, and recycle
Before creating a final product, engineers build this smaller version to test how something will work.
Model (or prototype)
Name an example of Kinetic and Potential energy.
Answers will vary
In a food chain, this group of organisms is responsible for producing their own food through photosynthesis. Give an example of one in this category.
Producers
Mountains, deep ocean trenches, volcanoes, and earthquakes occur in patterns along these.
Tectonic plate boundaries
What are resources that can be placed in human lifetime?
Renewable resources
Engineers follow this step-by-step process to test and improve their ideas before creating a final product.
The engineering design process
Name the types of energy waves, and give examples of each.
Answers will vary.
These organisms eat both plants and animals and play a role in transferring energy in a food chain. Give an example of an animal in this category.
There are three main types of rocks on Earth. Name them and describe how each one is formed.
Igneous, sedimentary, and metamorphic rocks?
Igneous rocks form when melted rock (magma or lava) cools and hardens.
Sedimentary rocks form when layers of sediment are pressed together over time.
Metamorphic rocks form when existing rocks are changed by heat and pressure.
This is the term for the wise use and protection of natural resources to make sure they last longer.
Conservation
What did our class engineer, to help what problem? What did we have to test to make sure the invention was made well?
Our class made prosthetics to solve the problem individuals losing their ability to use a limb.
