Titration, and the lab skills that are needed to support it, is detailed here, with the reasoning behind standard solutions, concentration and volumetric analysis covered. Your young lab assistants will learn the skills of determining...

The question of the structure and function of DNA being the same in almost all organisms is raised here. You will find this PowerPoint a great summary of the building blocks and replication of DNA. The differences between...

You can use these slides to explain the many complicated steps of the Polymerase Chain Reaction. The diagnostic and forensic uses of gel electrophoresis are detailed. This PowerPoint could be used to communicate facts, or to prompt...

You matter—unless you multiply yourself by the speed of light squared, then you energy! Scholars learn about matter, energy, the elements and so much more using an informative presentation. Completing the included worksheet creates a...

Wow! This comprehensive collection of slides will walk your chemistry class through the foundation of chemical reactions, teach them to balance equations, differentiate types of reactions, and calculate stoichiometry problems. This...

A great review of the structure and function of carbon-based molecules important to life, especially with relevance to humans. The chemistry behind the combination of polymers and the breakdown of bonds is covered. Valuable content...

The basics of mutation types and some potential effects of those are described and diagrammed here. Each detail is very clear and includes the labels and translation change exhibited. A great slideshow to expand on DNA replication issues.

After studying DNA replication and the genetics of inheritance, this slide show is useful for explaining specific mutations that can happen and result in an illness. Sickle cell anemia, and cystic fibrosis are explained on a genetic...

Covering the molecular interactions involved with DNA packing and the control of gene activity in depth, this slideshow is useful for higher-level biology students. The biochemical components of protein translation are diagrammed and...

Several slides compare different temperature scales. Thermal expansion, heat transfer, and Maxwell speed distribution are also explored. The last two slides seem unrelated to the topic of heat, but are easily left out of this otherwise...

In a neat and straightforward manner, this PowerPoint delivers basic introductory information on the properties of matter, physical and chemical changes, and pure substances vs. mixtures. It also defines the states of matter. For some...

Explore the causes of ozone depletion and the effect on plankton, algae, plants, amphibians, and humans. Learn how the Montreal Protocol has possibly helped reverse the decline of the ozone layer. Warning: photos of skin and eye...

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...

Show your chemistry class a graphic organizer classifying the types of chemical reactions. A few additional slides are included on the formation of magnesium chloride, the production of methanol, and a diagram of a mixture of molecules....

Listen and learn as you discover definitions for acid, base, and acid-base reaction. View example formulas of Arrhenius and Bronsted-Lowry acid and bases.

Acting as an overview from the General Chemistry Virtual Textbook, this site acts as one in a series of slides on acid-base systems. This particular slide deals with a diprotic acid, oxalic acid.

This lesson will explain what an acid is, what the pH of an acid is, and give an overview of the general properties of acids. It is 4 of 4 in the series titled "What is an acid?"

This lesson will show the difference in structure between deoxyribonucleic acid and ribonucleic acid. It is 3 of 4 in the series titled "DNA vs RNA."
