WHAT'S THE BEST TEMPERATURE? The water in some hot springs is too hot and too acid for most living things to survive. But not for the algae Cyanidium caldarium! Can you find the best conditions for this algae?

SAVE THE FOREST! Spruce Budworms can kill lots of trees in a forest. In 1950, scientists wanted to spray Spruce Budworms with a poison called DDT. They would save trees, but kill other insects and bigger animals too. What should they do?

FOREST FIRE! Forest fires burn old trees and make room for new ones. Heat from the fire opens Lodgepole pine cones so new seeds can sprout. What makes a forest fire big? How are forest fires different in younger and older forests?
