Hi Mr. Wood this is Caitlin from period 5! I’m so sorry this is late and all. Here are some of my journals! April 14: Can scientists really study something in nature without changing it? I think scientists can’t study something in nature without changing it because they have to test the nature product they are using with either a chemical or gas or fluid. April 12:What is an Aurora? A natural electrical phenomenon characterized by the appearance of streamers of reddish or greenish light in the sky, usually near the northern or southern magnetic pole. April 9: Do you have any ideas? I think the branch could have been chewed on by an animal that could have climbed or flew up on the tree. April 8:My dog vote is sky! April 7: why is there no tundra in HB? There is no tundra in HB because tundra is farther away from the equator so it’s more colder than HB. April 7: what defines tundra? A vast, flat, treeless Arctic region of Europe, Asia, and North America in which the subsoil is permanently frozen. April 7; why dont we have tundra in other places? We don’t have tundra in other places because they are closer to the equator.
