2. REMEMBRING LEVEL What was the most common source of heat energy in ancient times? It is a hot day, what should you wear? Why? List out the properties of a good source of energy? What was the main source of energy during the industrial revolution? Give few examples for how our ancestors used the energy possessed by the wind and water. Name the Raw material used in Thermal plants. “ Where does the energy we use come from? ” What is renewable energy? What are fossil fuels?

3. UNDERSTANDING LEVEL Explain two ways we use solar energy, coal, petroleum, hydropower, geothermal energy, wind energy, biomass, natural gas. Explain how the sun makes wind. Explain how the sun powers in the water cycle. Explain how hydro and wind energies are the indirect sources of solar energy? Explain the working of a solar cooker. What is the Indian name of bio-gas and why is it called so? Define solar energy. Define biomass.

4. APLICATION LEVEL Renewable Nonrenewable Which thermometer would have a higher temperature reading.
