5 active lessons about sustainability

How much water does it take to make a pair of jeans? Where do the parts in your phone come from? And what effect does greening your garden or balcony have? With the ImpactProject from the foundation Think Big Act Now, pupils discover the surprising and often invisible impact of daily choices. In 5 lessons, they work on current topics such as food, travel, and electronics. Through research, creative assignments, and discussion, they learn about sustainability in an active way.
