Humans are creative. They try to solve problems in original ways. For example, some scientists are thinking of ways to decrease the amount of greenhouse gases in the air. Other scientists are thinking of ways to limit the amount of sun that reaches Earth so that the Earth won’t get so warm. Like most ideas, there are pros (good
Textbooks say that carbon dioxide is a greenhouse gas and can make earth's climate hotter. Try this lab to see if carbon dioxide gas can really act like a greenhouse.
Objectives
Students should be able to make a hypothesis, perform an experiment, analyze data and write a conclusion based on the evidence from their experiment.
Given sets of graphable data students will show that various viewpoints can be supported depending on how data is presented and interpreted. These may or may not be accurate or relevant representations of data results over time. This lesson contains basic graphing components, interpretation of information and communication to others of findings depicted in graphs. Teachers may choose
The journal assignment involves students in current science research. Through the teacher’s journals, they will learn about how the research teams work together, design their research, tools that are needed and how they live and work in an extreme environment.
Objective
Students will be able to:
1. Understand how scientific research is conducted in an extreme environment
Working in groups, students will use common materials to create layers of snow and ice representing thousands of years of stratification. Groups will exchange their ice layers and extract core samples to analyze them.
Objective
Notice the phenomenon of stratification.
Notice that layers can tell a story of change over time.
Case studies provide a brief overview or examination of events that impact or alter the way people function and live day to day within the human and physical environment. They help by providing students with “real world” examples that relate to the theoretical content they are studying.
Objective
Students will prepare a case study illustrating the impact
