Jimmy traveled to a national park to explore the landscape and observe the

animals that live there. He noticed that several trees were knocked over onto the

road, and several power lines were damaged. Jimmy took a picture of the

damage to study later and then he went home. Jimmy’s friend visited the same

national park two days earlier, so Jimmy asked his friend to come over and look at

the picture he took. His friend is surprised by what he sees and shows Jimmy a

picture he took on his trip. Study the two pictures and the chart to decide what

happened. Thinking like a scientist, explain which event most likely caused the changes to

the national park.
