Outcomes: 1 Students will identify and describe examples of energy changes in everyday situations. 2 Students will classify materials as thermal conductors or insulators based on their ability to transfer heat. 3 Students will classify natural resources as renewable or nonrenewable based on their characteristics. 4 Students will identify and describe the type of energy produced by friction, specifically the generation of heat energy when rubbing hands together. 5 Students will identify and categorize different types of energy sources. 6 Students will identify and name renewable energy sources. 7 Students will describe and identify the energy change shown in a picture, recognizing how energy is transferred or transformed in different situations. 8 Students will identify fossil fuels and recognize which energy sources are not fossil fuels. 9 Students will explain chemical energy and identify examples of it in reallife situations, using a given image to support their understanding 10 Students will explain how human activities can change or affect the habitats of animals and plants. 11 Students will identify sound energy as a type of energy produced by vibrations. 12 Students will identify materials that are poor thermal conductors and understand how different materials transfer heat. 13 Students will identify and understand how energy can transform from one type to another. 14 Students will identify and describe different types of electric circuits.

15 Students will identify the percentage of energy outputs from incandescent and LED lightbulbs.

16 Students will describe how energy is transferred, including the conversion of energy from one type to another, and explain what happens when the circuit is broken.

17 Students will classify energy sources as renewable or nonrenewable and correctly identify whether statements about energy sources are true or false.

18 Students will identify and name types of thermal energy transfer, and describe the energy transformations in everyday examples.

19 Students will identify natural resources, explain their properties such as heat conductivity, describe the environmental impacts and also understand recycling materials

20 Students will identify and describe alternative energy sources, such as biomass, and explain their advantages. They will also learn how to interpret images to understand the percentage of each source of energy production.
