ANNOUNCEMENTS If you are on the waitlist, do not worry about it - you will get into the class. LECTURE Last week, you should have made observations on Strawberry Creek. Today, you should go and note differences in water - the color, and the rate of water flow from last week. You should ask yourself “why is the water different this week than it was last week?” This is what science is - asking questions about your observations. Today, I will explain to some extent why changes in the creek are occurring. This comes under the topic of climate. Climate is an area’s average weather. Two things important to weather are temperature and precipitation. These predictions are made day-to- day. However, weather is simply averaged out and climate is the long term average of weather. The climate of a region is determined by many factors such as the sun coming in, water movement, air movement, gases in the atmosphere…etc. The climate affects plants and human activities that remove or alter vegetation. A biome is a cluster of plants. One of the most interesting aspects of our area is a biome, the Redwoods. Our climate in the Bay Area is made up of two main elements. One is the very short, fairly cool interval. The other is the very long very warm interval. The plants in the area are equipped to survive in both the long dry seasons and the short cool intervals. The Redwoods, as I mentioned last time, need moisture year round, which they get from the fog. The Redwoods that you see on campus, are part of the mission of landscapers to make the campus pretty. Right now, we are in the short wet period. You will notice that the rainfall that occurred the week of school starting is our cool short interval. Today when you go to Strawberry Creek, you don’t see the same turbulence and volume of water that you saw last week. The gravity does not change, but the
