Eureka! Module - Lesson 4: Invention & the Economy
Objectives: In this lesson, students will differentiate between invention and entrepreneurship. Students will explain that an inventor develops a new good or service to help solve problems and/or increase productivity (i.e. more goods or money in less time). Students will explain that an entrepreneur is someone who risks money to bring a new or improved product (invention) or service to market. An entrepreneur may or not be the inventor.
Vocabulary: entrepreneur, income, profit, productivity, revenue, employee, employer Description: The purpose of this lesson is to teach students how inventions impact the economy by bringing jobs or other resources to a community.

Lesson can take 45-60 minutes to complete.
Introduce the lesson by asking students if they ever had a lemonade stand or in the example highlighted within the activity sheet, a blueberry pie stand (the blueberry is New Jersey’s state fruit!). Ask: Why did you or why would someone have a blueberry pie stand? (To make money). Ask them to turn and talk to a classmate about all the things they would need to buy in order to have a blueberry pie stand.
Have the students share all the things they need to buy (flour, sugar, eggs,). Explain that they would need to buy all of these things before making any money. So the money they spent is their start – up cost. Ask students if they know what profit means. Explain that profit is the money left over from the sale, after the entrepreneur pays all of the cost. (Use activity sheet, “A Blueberry Pie Stand”.)
Explain that when more work can be done in the same period of time, it is called an increase in productivity. (Use activity sheet, “A Horse Grooming Business”.) Explain that by grooming more than one horse at a time, the entrepreneur was able to increase their profit, making more money.
Ask students to think about the inventions they are learning about. Work in a small group to choose an invention to explain how it has impacted the economy. (Use the worksheet, “5 W’s of inventing” to help students organize their thoughts).
To close the lesson, have students complete an Exit Slip showing what they learned from the lesson. Or, you can make a list of inventors and their inventions. Have students decide if the inventor is simply an inventor or an entrepreneur.
