Climate Change
What is global warming and name one type of human activity that causes it
The long term increase in the Earth's temperature by human activities such as burning fossil fuels, industrial processes and deforestation
What is the material inside solar panels that absorbs the sun's energy and get excited?
Silicon.
What is Engineering?
the applications of maths and science to solve societal problems.
Name 5 types of natural resources
water, wind, coal, natural gas, forests
Describe how the greenhouse effect occurs to keep the planet warm and livable.
1. Solar radiation, 2. Heat emitted form Earth, 3. Greenhouse gases trap heat, 4. Earth is warmed up.
What is renewable energy.
Renewable energy does not run out and are replenished faster than they are used up.
Name 5 types of engineers
Mechanical, Electrical, Chemical, Industrial, Civil
Name 2 Caribbean Islands with wind farms
Jamaica, Curacao, Aruba, Bonaire, Puerto Rico.
What are greenhouse gases and give 3 examples:
Greenhouse gases trap heat from the sun contributing to the greenhouse effect. 3 examples are methane, water vapour and CO2
Name 5 types of renewable energy.
Solar power, Wind power, Hydroelectric power, Biomass energy and Geothermal energy
What do electrical engineers do?
they create electric-powered technology including devices, electrical components and systems.
Name 3 types of non-renewable energy.
Coal, oil, natural gas, nuclear energy
Name 4 things we can do to reduce our carbon footprint?
recycle, save water, eat organic, reduce waster, renewable energy etc.
Describe how Hydroelectric power is generated
dams force water in a river or stream through a narrow pipe containing a turbine which spins as the water flows to power a generator creating electrical energy.
Outline the steps in the Engineering Design Process.
Define the problem, Do your research, Develop possible solutions, Design your solution, Build a prototype, Test it, Evaluate your solutions.
What is the name of the strong winds in Trinidad that can be used to power wind turbines?
North-East Trade Winds.
Name 3 impacts of climate change
melting of polar ice caps, rising sea levels leading to flooding, drought, more powerful storms, forest fires.
Give 2 advantages and 3 disadvantages of wind turbines.
Adv. More power on a windy day, does not pollute, no greenhouse gas emissions, job creation, cheap energy source. Disadv: Unpredictable, Threat to wildlife, Noise, Looks
Name 5 things which Civil Engineers build
Roads, buildings, dams, tunnels, bridges
Define sustainability.
Meeting our present needs without compromising the ability of future generations to meet their own needs.
