3rd Pollution/Conservation Study Guide S3L2 Students will recognize the effects of pollution and humans on the environment Key Vocabulary: natural resource-a material that is found in nature and that is used by living things. renewable resource –a resource that can be replaced during a human lifetime. nonrenewable resource –a resource that, when it is used up, cannot be replaced in a human lifetime. EQ: What are some natural resources? Examples of natural resources: salt oil rocks/ minerals water tree cow Examples of renewable resources: creek tree rain plant Examples of non-renewable resources: animals gasoline natural gas soil coal EQ: What is the difference between renewable and non-renewable resources? A renewable resource is a resource that can be replaced during a human lifetime. Plants and animals are renewable resources. People use animals for food and clothing. Water is our most important renewable resources. A non-renewable resource cannot be replaced during a human lifetime. Oil is a non-renewable resource. Key Vocabulary: pollution – harmful material in the environment air pollution – harmful material in the air water pollution – harmful material in the water 3rd Pollution/Conservation Study Guide S3L2 Students will recognize the effects of pollution and humans on the environment land pollution – harmful material on land habitat – the place where a person or an animal lives Smog is a mix of smoke and fog and it harmful to our environment. Pollution in the air makes it difficult for us to breathe and it can also change the weather. Smoke traps heat from sunlight and this can make the earth warmer. EQ: How do people affect the environment? People effect the environment in three ways: air pollution, water pollution, and land pollution. AIR POLLUTION Driving cars pollutes the air and if we can walk, we are cutting down on air pollution. Some factories also release smoke into the air which leads to air pollution. WATER POLLUTION Pollution can harm water too. When trash and oil is dumped into the water, the water becomes polluted. It can then make animals sick. Some water treatment plants can clean the water, but other times, the water cannot be cleaned up. LAND POLLUTION When people use the land, they change it. Sometimes we change it in good ways and sometimes we change it in bad ways. When we litter, we pollute the land which is harmful to the land. Other times we change the land in good ways, such as planting trees and flowers. Land pollution can also pollute the water making it unsafe for us to use. Key Vocabulary: conservation – saving resources by using them wisely reduce – to use less of a resource reuse – to use something again and again recycle – to break down a product and use its material again EQ: How can our natural resources be used wisely? We can use our natural resources (oil, water, trees, animals, etc.) wisely by reducing the amount of trash we accumulate. We can also reuse items, or use them more than once, instead of throwing them away. Additionally, we can recycle all materials that are recyclable, therefore cutting down on the amount of trash we put in landfills. Humans can plant trees in order to conserve our natural resources. We can also be careful how much water we waste by not filling the bathtub all the way up or not running the water while we brush our teeth. 3rd Pollution/Conservation Study Guide S3L2 Students will recognize the effects of pollution and humans on the environment
