Engineering design Process
What are good designs able to do when it comes to constraints?
Overcome the constraints.
The ability of a liquid to flow through a substance.
permeability
How are natural resources distributed across the Earth?
Unequally distributed.
Explain how land could affect the way natural resources are distributed across the Earth.
Different soil can be more fertile than others.
Which scientist is credited for the discovery of natural selection?
Charles Darwin.
Is it possible for the Engineering Design Process to come up with a solution to the problem after the first attempt?
Yes
When a rock has pore space water can enter through.
Porosity
An underground layer of permeable rock that can hold groundwater or allow it to flow through.
Aquifer
Explain how altitude could affect natural resources that are distributed across the Earth.
Mountains cause changes in oxygen levels.
The idea that creatures will pass along traits to help them survive because those that don't have the traits will die off sooner.
Natural selection
How many solutions to a problem are possible when using the Engineering Design Process?
Many possible solutions.
Are fossil fuels considered renewable or nonrenewable resources and why?
Nonrenewable because it takes over a lifetime to reproduce.
why would gravel be the best material to use when building an aquifer?
It allows water to enter into the pores and allows the water to flow between the pores.
Give three reasons why freshwater is considered a limited resource.
1) only 3% of Earth is freshwater.
2) 2% of freshwater is frozen.
3) Only found in lakes, rivers, ponds, wetlands, and streams.
Humans pick/choose and are allowed to determine the offspring wanted as a result.
Selective breeding.
What are the four main types of bridges?
Suspension, Arch, Beam, Cable.
What are the three types of fossil fuels?
Coal, Oil, Natural Gases.
Explain how climate could affect the way natural resources are distributed across the Earth.
If it's very hot and dry, there may be less vegetation which could affect the growth of plants and animals.
Water that collects or flows beneath the Earth's surface in the soil or the pores and cracks of rocks.
Groundwater
The differences among species such as different beaks found on birds.
Variations in genetics.
What is the list of the Engineering Design Process in the correct order?
Ask, Imagine/brainstorm, plan, create, test, improve, and share.
Which fossil fuels come from living organisms that died millions of years ago?
Coal and Oil.
What are two explanations for why not every area in the United States has copper?
1) The distribution of natural resources depends largely on the geology of an area.
2) Different geologic process occurs in different places in the world which allows for different natural resources to form.
Water which is found above the Earth's surface.
Surface water.
A random and permanent change within a gene.
Mutation.
