1. Teacher Guide This lesson is designed to teach kids to ask a critical thinking question that you can’t just put into a search box to solve. To do that, we encourage them with smaller questions that search can help them answer. Make sure that you read the notes for each slide: they not only give you teaching tips but also provide answers and hints so you can help the kids if they are having trouble.

3. The western slope of the Olympic Mountains, on Washington state’s Olympic Peninsula, includes the cool, shady environs of the Hoh Rainforest. A temperate rainforest, the Hoh’s canopy features some Sitka spruce and western hemlock trees that reach more than 300 feet above the forest floor. This moss-covered outcropping on the forest floor shows just how quickly any stationary object in the Hoh Rainforest becomes a staging ground for new plant growth. Even the trees that fall in the Hoh become a prominent part of the forest’s lifecycle. A fallen tree can become what’s often called a “nurse log.” A nurse log provides more open real-estate for moss and ferns to grow, and, as it decays, it creates an ecological foundation for young saplings eager to take hold and join the ranks of the massive trees that populate the Hoh.
