The carbon dioxide in our atmosphere and its effect on how heat is contained is summarized here. The flow of heat is explained with details about insulation and conduction. There are diagrams of heat circulation on a global level and...

The majority of this presentation is a collection of diagrams and graphs that back your lecture on biogeochemical cycles. The last few slides define ecosystems and the Gaia hypothesis. You may find these slides valuable, but will...

The feedback mechanisms of metabolism of a variety of substances in the human body. Carbohydrates, lipids, amino acids, and their derivatives are explained. The biochemistry required to explain the metabolic balance and feedback controls...

A review of a full unit on energy and matter, this slide show starts with basic definitions of states of matter and their mass. It then develops the ideas of the forces that that matter can exert. Details about bonding within matter and...

The principles of pollution control on a molecular level are summarised here. The reasoning and study behind the principles are described, and your class will undestand how some techniques are developed to be more efficient.

The eight slides here progress through the stages of the extraction of iron from its ore. They include the reasons for the process, method overview, and reactions. A slide show produced by students, it is a good example of correct...

Every living thing requires a food source, thus the interconnections in ecosystems become complex. Scholars learn about these interconnections in a presentation on energy flow. It starts with the sun and moves through many different...

This plant structure and function PowerPoint addresses the main organs and the factors that affect its development as well as going into detail about the specializations at a cellular level.   The cell functions and system...

This presentation begins with the many problems multicellular organisms which rely on diffusion encounter. There are many diagrams of mammalian organ structures, and they are labelled with their relevant functions. This an excellent...

Earth's atmosphere is full of different energies, from thermal to wind to electromagnetic radiation. Through the presentation, class members discover these energies and how they determine weather patterns.

If you need a comprehensive review of the development of Earth's atmosphere through the ages, then this is for you! The presentation starts with a introduction to theories of planet formation and initial distribution of isotopes in the...

Here is a suitable set of slides to use when teaching about the layers of the atmosphere, climate, global winds, and types of clouds. These slides will support a few different lectures. You will probably want to replace the diagrams with...

Take a trip in a "time machine" to see a series of pictures that show the how the climate of Earth has been changing. The indicators shown are: sea ice, sea level, carbon dioxide, and global temperature.
