- 1Protecting Natural ResourcesConservation efforts protect natural resources and biodiversity. Reducing waste, recycling, protecting habitats, and using renewable energy all help preserve Earth's resources.Experiment
- 2Why Biodiversity MattersBiodiversity—the variety of life in an ecosystem—makes ecosystems more resilient. Loss of biodiversity from human activities threatens ecosystem stability worldwide.Lesson
- 3Where Our Materials Come FromEvery manufactured object begins as a mined, farmed or drilled raw material. Tracing a phone or a jumper back to its sources shows the real cost of a product, and it is the first step in deciding what to reuse rather than replace.Lesson
- 4Reduce, Reuse, Recycle — in That OrderThe three are ranked, not equal. Reducing avoids the material entirely, reusing avoids reprocessing, and recycling still costs energy and loses quality each cycle. Treating recycling as the first answer misses the two larger savings.Experiment
- 5Saving Energy at HomeThe biggest household energy savings are usually not the ones people think of. Heating and hot water typically dwarf lighting, so insulating a loft saves far more than switching off a lamp — even though the lamp is easier to notice.Experiment
- 6Where Drinking Water Comes FromWater is collected from rivers, reservoirs or underground, then screened, settled, filtered and disinfected before it reaches a tap. Each stage removes something different, and skipping any one of them makes the water unsafe.Experiment
