Discuss the following questions with your group and write down

your answers using complete sentences. Think carefully and try to remember what you have learned in other science classes. We will discuss your answers in class and this sheet will be collected from each student once we have completed our discussion. This activity will help you make the most out of watching the video about how Einstein came up with his famous equation: E = mc².

Energy

1. What is energy?
2. What kinds of energy are there?
3. What are the primary sources of energy in our everyday lives?
4. Contrast stored energy (like the energy found in the food you eat) with useful energy like light. Give at least three examples of stored energy besides food and three examples of useful energy besides light.
5. What do all kinds of stored energy have in common?
6. What do all kinds of useful energy have in common?
7. What is the difference between stored and useful energy in general?

Matter

8. Consider the following things: air, water, living organisms, the sun, jewelry. Are these items made of matter? Identify the elements that each of these things are made of using a periodic table and what you have learned in other science classes.
   air            water            living organisms            the sun            jewelry
9. Do elements in the periodic table have mass? Write the symbol and the mass of one atom of each element you named above.
10. What is weight?
11. What is mass?

12. What is the difference between weight and mass?
13. List at least five things from your everyday life that you would like to find out what they are made of.

While you Watch

Science is a human endeavor undertaken by many different individuals of various social and ethnic backgrounds who carry out their science in the society in which they live. Organize yourselves into seven teams. The teams will have the following names:

Each team is responsible for taking notes about the topic covered by your team’s name. Students should record the name of the scientist(s) who worked on that topic, the scientists’ nationality, whether the scientist worked alone or with others, and the society and times in which each scientist lived. Take notes on the blank space below and on the back of the attached handout. Write as legibly as possible, please! These will be collected along with your answers to the questions. See the attached handout for precise directions about what to do while you watch. Your team will be responsible for presenting the information you learned about your scientist(s) to the rest of the class.
