Description

In this activity, students learn about the relationship between greenhouse gases and global warming through a simple teacher demo or hands-on lab activity. Everyday materials are used: beakers, baking soda, vinegar, candle, thermometers, heat source such as a goose-necked lamp, etc. Students shine a light onto three thermometers: a control, an upside down beaker w/ a thermometer and air, and a beaker in which CO2 had been poured.

MS-ESS3-5 Ask questions to clarify evidence of the factors that have caused the rise in global temperatures over the past century.

Analyze and interpret data to provide evidence for phenomena.

Ask questions to clarify and/or refine a model, an explanation, or an engineering problem.

Construct an explanation using models or representations.

Construct, use, and/or present an oral and written argument supported by empirical evidence and scientific reasoning to support or refute an explanation or a model for a phenomenon or a solution to a problem.

Develop or modify a model—based on evidence – to match what happens if a variable or component of a system is changed.

Develop and/or revise a model to show the relationships among variables, including those that are not observable but predict observable phenomena.

Communicate scientific and/or technical information (e.g. about a proposed object, tool, process, system) in writing and/or through oral presentations.

Conduct an investigation and/or evaluate and/or revise the experimental design to produce data to serve as the basis for evidence that meet the goals of the investigation.

Weather and climate are influenced by interactions involving sunlight, the ocean, the atmosphere, ice, landforms, and living things. These interactions vary with latitude, altitude, and local and regional geography, all of which can affect oceanic and atmospheric flow patterns.

Human activities, such as the release of greenhouse gases from burning fossil fuels, are major factors in the current rise in Earth’s mean surface temperature (global warming). Reducing the level of climate change and reducing human vulnerability to whatever climate changes do occur depend on the understanding of climate science, engineering capabilities, and other kinds of knowledge, such as understanding of human behavior and on applying that knowledge wisely in decisions and activities.

Cause and effect relationships may be used to predict phenomena in natural or designed systems.

Time, space, and energy phenomena can be observed at various scales using models to study systems that are too large or too small.

Models can be used to represent systems and their interactions—such as inputs, processes and outputs—and energy and matter flows within systems.

Energy may take different forms (e.g. energy in fields, thermal energy, energy of motion).

Patterns can be used to identify cause-and-effect relationships.

Explanations of stability and change in natural or designed systems can be constructed by examining the changes over time and processes at different scales, including the atomic scale.
