1.7 - Weather and Seasonal Changes

The student will investigate and understand weather and seasonal changes. Key concepts include

a)  changes in temperature, light, and precipitation affect plants and animals, including humans;

  •  identify types of precipitation as rain, snow, and ice and the temperature conditions that result in each one. Bloom's Level:  Knowledge / Understand
  • compare and contrast the activities of some common animals (e.g., squirrels, chipmunks, butterflies, bees, ants, bats, frogs, and humans) during summer and winter by describing changes in their behaviors and body covering. Bloom's Level:  Analyze
  • compare and contrast how some common plants (e.g., oak trees, pine trees, and lawn grass) appear during summer and winter.Bloom's Level:  Analyze
  • comprehend at an introductory level that some animals respond to seasonal changes by hibernating (e.g., frogs, bats) or migrating (e.g., some birds and butterflies). (It may be useful to recognize common Virginia animals that hibernate and migrate, but the specific names of animals are not the focus of student learning here.) Bloom's Level:  Understanding
  • infer what the season is from people’s dress, recreational activities, and work activities. Bloom's Level:  Analyze

b)  there are relationships between daily and seasonal changes; and

  • predict how an outdoor plant would change through the seasons.  Bloom's Level: Analyze / Apply
  • compare and contrast the four seasons of spring, summer, fall (autumn) and winter in terms of temperature, light, and precipitation.  Bloom's Level: Analyze

c)  changes in temperature, light, and precipitation can be observed and recorded over time.

  • relate a temperature, light, and precipitation chart to the corresponding season (daily or weekly).  Bloom's Level: Understand

BIG IDEAS

Weather and seasonal changes affect plants, animals, and people.


UNDERSTANDING THE STANDARD

  • Seasonal changes bring about changes in plants, animals, and people.
  • With seasonal changes come changes in weather, including temperature, light, and precipitation.
  • Precipitation includes rain, snow, and ice.
  • Changes in plants include budding, growth, and losing leaves.
  • Some animals hibernate and some animals migrate as a result of seasonal changes, resulting in changes in habitat. Students do not need to know the terms migration, hibernation, and habitat. The focus should be on the concepts, not the terminology.
  • Hibernation is a state of greatly reduced metabolic activity and lowered body temperature adopted by certain mammals as an adaptation to adverse winter conditions. Most animals are not “true hibernators” but rely on a combination of reserve body fat, stored food supplies (in rodents only), and a protected den to enable it to survive the winter. At intervals of several weeks the animal elevates its body temperature, awakens, moves about, feeds, and then returns to its state of torpor.
  • Migration is the regular, usually seasonal, movement of all or part of an animal population to and from a given area. The distance traveled may be a few miles or several thousands of miles. Animals migrate for many different reasons. Some animals migrate to find better sources of food, water, or shelter. Other animals migrate to visit particular breeding grounds, rear their young, or find warmer climates. The frequency of animals’ migrations also differs.
  • An animal's living place is called its habitat. Most animals are only adapted to live in one or two habitats.Earth has many different environments, varying in temperature, moisture, light, and many other factors. Each of these habitats has distinct life forms living in it, forming complex communities of interdependent organisms. A habitat must include a source of food for the animal, a source of water for the animal, access to some sort of shelter for the animal, and an adequate amount of space so that enough habitat components are available to the animal. Some animals’ habitats are very small, but some animals require a large amount of space.
  • The body coverings of some animals change with the seasons. This includes thickness of fur and coloration.
  • Changes made by people include their dress, recreation, and work.


ESSENTIALS

Essential Questions:

·  What happens to plants when weather and seasons change?

·  How do animals adjust to weather and seasonal changes?

·  How do people adjust to weather and seasonal changes?

·  How can weather be observed and recorded over time?

In order to meet this standard, it is expected that students will

  • identify types of precipitation as rain, snow, and ice and the temperature conditions that result in each one.
  • relate a temperature, light, and precipitation chart to the corresponding season (daily or weekly).
  • observe and chart changes in plants, including budding, growth, and losing leaves. Recognize in what season budding and losing leaves will most likely occur.
  • predict how an outdoor plant would change through the seasons.
  • compare and contrast the four seasons of spring, summer, fall (autumn) and winter in terms of temperature, light, and precipitation.
  • compare and contrast the activities of some common animals (e.g., squirrels, chipmunks, butterflies, bees, ants, bats, frogs, and humans) during summer and winter by describing changes in their behaviors and body covering.
  • compare and contrast how some common plants (e.g., oak trees, pine trees, and lawn grass) appear during summer and winter.
  • comprehend at an introductory level that some animals respond to seasonal changes by hibernating (e.g., frogs, bats) or migrating (e.g., some birds and butterflies). (It may be useful to recognize common Virginia animals that hibernate and migrate, but the specific names of animals are not the focus of student learning here.)
  • infer what the season is from people’s dress, recreational activities, and work activities.
