In the Planet Protectors eBook, three friends notice that changes have occurred in their local park over the past five years. These friends want to figure out what has happened to the park and why these changes have occurred. In order to do this, they explore how humans have contributed to the air, land, and water pollution of the park. One way in which they investigate these changes is by conducting tests for environmental pollutants. They also learn how deforestation impacts the environment and adds to the effects of pollution. As the characters, along with the learner, progress through this eBook, they explore actions they can take to reduce pollution in their homes, schools, parks, and neighborhoods. Some of these actions include reducing wastes, reusing materials, recycling products, and composting. These actions are all aimed at teaching them what it means to take responsibility for the quality of the environment. In the Peeking Inside Plants eBook, learners explore plant structures (stems, leaves, flowers, roots, and fruit) in order to build an argument about how these internal and external structures are responsible for the growth, survival, and reproduction of plants. Learners are joined by Abe, a junior wildlife expert at a nature preserve. Abe guides the learners as they explore, through the interactive elements of the eBook, how these structures are integral to plants as well as how different plants have specific types of structures depending on the environment in which they live.
