From the light reaction to the Calvin cycle, this presentation contains information about the various stages of photosynthesis.  This is a great supplement to some of the biochemistry-heavy presentations about the specific...

Diagrams with annotations are shown on each of these eighteen slides, which summarize the processes of respiration. The focus is on the 3-step oxidation process and the Krebs cycle.  Students should be able to follow these slides...

Interested Earth enthusiasts are introduced to ice ages. The 26,000-year cycle is charted and the eras named. Several slides are dedicated to the carbon cycle and how it contributes to the changes. The reasons for the cooling of the...

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...

Three lab guides are given here that detail experiments to illustrate the oxidation of glucose for the production of ATP. The first will compare photosynthesis and respiratio and show theimporatnce of both to plants. The next will show...

Both aerobic and anerobic respiration are introduced in this succinct PowerPoint. The chemical equations for both are included. The last slides give instructions for a lab activity in which pupils use a gas sensor to measure the...

This slide show progresses through a comprehensive review of the grounding principles of earth science. Get down and dirty with the details of fossil fuels! Help your geologists to have a rock solid understanding of the rock cycle. The...

Eight slides of information related to shifts in the climate make up this presentation. The vocabulary and concepts displayed are geared toward high school meteorology learners. Content is not cohesive from slide to slide, but the...

Excellent diagrams, labels and summaries make this resource be valuable to your students throughout the topic of circulation. All types of circulation vessels are explained, their structure and function is detailed, and the overall...

Ginkgo trees existed for more than 350 million years, and, at this time, only one species still remains. While plant diversity generally increases over geologic time, some interesting exceptions occur. Young scientists learn about plant...

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.

An extensive investigation of the Earth's climate changes awaits your environmental science classes. This top-notch presentation begins by looking at the history of Earth's climate and then predicts the impact on each major terrestrial...

The need for a respiratory system in humans versus being reliant on gas exchange structures is demonstrated. There are many details about the advantages and disadvantages of each mechanism.  Students are able to learn about the...

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 complete overview of oxidation, reduction, and how electrons are moved in respiration. You could use this slide show to elaborate on the concept of harvesting stored energy, and to summarize the stages of aerobic and anaerobic metabolism.

If you need summary notes for independent study, or a Powerpoint to review as a class, then these slides will fit your need. There are really great, quite detailed, diagrams and some slides to summarize the 2 stages of reactions in...

Quite a detailed and advanced look at the transport mechanisms of a plant. The absorption and control of sugar and water concentration are explained and will help an understanding of homeostasis concepts and organ specialization.

All aspects of the photosynthesis process, and the way that plants have adapted with specializations are detailed here.  The diagrams and info-graphics will be useful to your AP biology class. It could also be used as a review...

From types of rocks to types of weathering, learners gain knowledge on minerals, composition of soil, and the effects of weathering on Earth.

Leaf structure and its specializations for photo-respiration are detailed here.  Slides provide information about Photo-respiration biochemistry and its impact.  A class learning about classic respiration will appreciate the...
