More than 4,000 Houston Independent School District elementary and middle school students will set up shop this weekend with creative lemonade stands to learn more about how to start, own and operate their own business.

Lemonade Day, officially scheduled for Sunday, is a citywide hands-on learning program sponsored by Prepared 4 Life, a nonprofit organization dedicated to the empowerment of middle-school-age children. The organization aims to teach students how to become successful entrepreneurs with a strategic 14-step process, which encompasses the ideas of spending, saving, and sharing with the community. HISD students will participate in Lemonade Day activities on Friday and Sunday.

Students from Neff Elementary School will serve lemonade and a lemonade-iced tea mix, donating some of their profits to Houston’s flood-relief efforts.

Sixth-grade students from the Young Women’s College Preparatory Academy have concocted raspberry lemonade in honor of late musician Prince. The students will use their profits from Lemonade Day to raise funds to travel to Miami for a national STEM (Science, Technology, Engineering and Math) competition.

Students participating in Lemonade Day at Blue Triangle will be judged on their lemonade stands and will receive awards for the best-tasting lemonade, best lemonade stand, and best lemonade presentation.
