Copy the list of words Look for a relationship among the words in each list. Cross out the word in each list that does not belong with the others. Circle the word in each list that is a category that includes the others. Explain how the word you circled relates to the other words in the list, and how the word you crossed out does not fit in the list.

What are a few examples of the second word sort where energy is absorbed or released during an interaction? Share your thoughts with the class.

Read the introduction and look for key ideas

Can you follow the transforming energy? Most of the energy found here on Earth can be traced all the way back to the Sun.

Which cards are relevant to home energy efficiency? How does the Law of Conservation of Energy relate to the home? How does energy transformation relate to the home? Discuss your thoughts with the class.

Analysis question 1 Copy the lists of words. Look for a relationship among the words in each list. Cross out the word in each list that does not belong with the others.

Analysis question 1 Copy the lists of words. Circle the word in each list that is a category that includes the others. Explain how the word you circled relates to the other words in the list, and how the word you crossed out does not fit in the list.

Analysis question 2 The diagram below shows the transfer of energy from the Sun all the way to a student using a computer. Using the table on the previous page, decide on the type of energy at each of the situations. There may be more than one energy type at each place.

Key vocabulary definitions Chemical energy – A type of potential energy where the energy is stored in the bonds of atoms. Elastic energy – Potential energy that is stored by stretching or compressing.

Key vocabulary definitions Electrical energy – Electrical energy stored by the buildup of charge (electrons or ions). Gravitational potential energy – Energy stored due to an object’s mass and height. Heat – The movement of thermal energy from hot to cold.

Key vocabulary definitions Kinetic energy – Energy of motion. Light - A type of kinetic energy that is transferred by the rapid movement of electromagnetic fields. Nuclear energy - A type of potential energy that is stored in the nucleus of an atom.

Key vocabulary definitions Potential energy – Energy of position or stored energy. Sound - A form of energy that is transferred through air, water, and many solid materials by the vibration of an object.

Key vocabulary definitions Thermal energy – Energy that is transferred from a warm object to a cooler object.
