Final answer:
Two examples of educational activities for increasing intake of calcium-rich foods among teenage girls are hands-on cooking classes and nutrition workshops or seminars.
Step-by-step explanation:
One example of an educational activity for increasing intake of calcium-rich foods among teenage girls is to include hands-on cooking classes that focus on creating meals that are high in calcium. This can help educate the girls about the importance of calcium and provide them with practical skills to incorporate calcium-rich foods into their diet. Another example is to organize nutrition workshops or seminars that specifically address the benefits of calcium and provide information on calcium-rich food sources. These workshops can be interactive, with games, quizzes, and discussions to engage the students and increase their motivation to consume more calcium-rich foods.
