The Lesson Plan – Energy Efficiency and Conservation
Science – 3-5-ETS1-2
Generate and compare multiple possible solutions to a problem based on how well each is likely to meet the criteria and constraints of the problem.
Language Arts – LAFS.K12.W.1.1
Write arguments to support claims in an analysis of substantive topics or texts, using valid reasoning and relevant and sufficient evidence.
Mathematics – MAFS.5.NF.1.2
Solve word problems involving addition and subtraction of fractions referring to the same whole, including cases of unlike denominators, e.g., by using visual fraction models or equations to represent the problem. Use benchmark fractions and number sense of fractions to estimate mentally and assess the reasonableness of answers.
Energy conservation is any behavior that results in the use of less energy. Energy efficiency is the use of technology that requires less energy to perform the same function.
- Using what we know about science, what impact does energy efficiency and conservation have on the natural world around us?
People around the world are using more electricity as technology increases. As populations increase, so does the demand for electricity. The importance of energy efficiency and conservation are often overlooked. Losses in generated electricity can occur during conversion and transmission of electricity. We must find ways to minimize this. There are numerous benefits associated with the use of less energy in our homes, schools and within our community. Whether you decide to use energy-efficient equipment or change the type of bulbs you are using in your home, you will find that the reduction of energy consumption is not only good for the environment, it is also good for your wallet.
- What does being more efficient mean?
- Why is it important for us to find ways to maximize efficiency of our energy sources?
- What is fuel efficiency?
- How can energy be lost?
- How can we minimize losses in electricity?
- How can we make homes/buildings more energy efficient?
- What can be done to minimize the need for new power plants?
- What is the difference between energy efficiency and energy conservation?
Wind power involves turning energy from the wind into other forms of useful energy. In some countries such as Denmark and Portugal, wind power contributes around 20% of the total electricity production. What fractional amount of total electricity produced does NOT come from these two countries?
The answer is:
80/100 or 4/5
