Note: This activity is for kids ages 9+. It can bring up issues not suitable to young children.
Before starting this project introduce kids to world issues through books about global issues. Three of my favorites are Little Things make Big Differences; A Story About Malaria about illness and medical resources, One Plastic Bag about the effects of litter and pollution and Maddi's Fridge about homelessness and hunger. All of these books are made for children and approach global issues in a way kids can understand.
After you read a few books to the kids and they have exposure to global issues ask them to pick a world issue they feel strongly about.
Have the children research those issues.
Have them put together a 10 photo about this issue. They can use pictures they find in newspaper, magazines and websites dedicated to the cause. Make it clear to the kids you are not asking them to solve anything or come up with a solution to a world problem, but to bring awareness to world issues.
Give the children an opportunity to present their project to other students, adults, or parents. They can do this through a power point, a display board or a speech. You can host a quick global awareness night where children can present these issues to parents and fellow students.
