4th grade physical science unit focusing on waves and transference of energy.
Students learn how the greenhouse effect is related to global warming and how global warming impacts our planet, including global climate change. Extreme weather events, rising sea levels, and how we react to these changes are the main points of focus of this lesson.
This video segment adapted from NOVA/FRONTLINE examines the greenhouse effect, its role in keeping Earth habitable, and the industrial changes that have led to an increase in the planet's average temperature.
This is the first of three lessons in greenhouse operation and management. This lesson introduces learners to components of greenhouses and the ways greenhouses benefit growing conditions. The presentation covers types of greenhouses, covering materials, and benefits and downfalls to these characteristics.
Students observe demonstrations, and build and evaluate simple models to understand the greenhouse effect and the role of increased greenhouse gas concentration in global warming.
This resource is a video abstract of a research paper created by Research Square on behalf of its authors. It provides a synopsis that's easy to understand, and can be used to introduce the topics it covers to students, researchers, and the general public. The video's transcript is also provided in full, with a portion provided below for preview:
"Long-term mono-cropping often suppresses plant growth, but the mechanisms behind this are poorly understood. The key may lie in the soil surrounding the plants’ roots. This region, the rhizosphere, is filled with important microbes and the carbon-containing photosynthesis products, rhizodeposits, that plants exude from their roots. Rhizodeposits are part of the link between plants and their rhizosphere microbes. So, a team of researchers examined the interactions among rhizodeposits, rhizosphere microbes, and mono-cropping long-term. They found that years of mono-cropping led to a gradual decrease in carbon deposition and the chemical diversity of the rhizodeposits. These decreases were strongly correlated with decreases in the rhizosphere microbial diversity and metabolic functioning. Mono-cropping long-term also slowly led to a decrease in the abundance of plant-beneficial microbial groups..."
The rest of the transcript, along with a link to the research itself, is available on the resource itself.
Students learn about the advantages and disadvantages of the greenhouse effect. They construct their own miniature greenhouses and explore how their designs take advantage of heat transfer processes to create controlled environments. They record and graph measurements, comparing the greenhouse indoor and outdoor temperatures over time. Students are also introduced to global issues such as greenhouse gas emissions and their relationship to global warming.
