High school or college horticulturists will appreciate this PowerPoint on seed-propagation. It walks them through the science behind seed production and germination as well as the requirements for growing plants from this stage....

Diagrams bring barometers to light in this PowerPoint. Several slides explain the structure and function of this apparatus. The relationship of air pressure to the processes of evaporation and boiling are also explained. This would be an...

Steps of the scientific method are summarized, and then an example experiment is presented to allow practice identifying the steps. The graphics and animations are a little blurry, but this otherwise well-formulated presentation will...

A combination of informative text, photos, and graphics comprise this sharp show on electromagnetic radiation. Some slides mention hands-on activities for demonstrating concepts, so if you want to include them you will need to figure out...

When an object is heated or cooled, a change occurs. Learners will work through this presentation and decide whether or not the changes are reversible. They learn about heating and cooling, then assess changes that have taken place. This...

Provide physical science explorers an overview of magnetism with this collection of slides. The third slide posts hyperlinks to websites that cover magnetic fields in detail, so ideally this presentation would be viewed by small groups...

What is gravity and how do you explain it? Use this presentation to guide an inquiry-based lesson centered on understanding gravity through hands-on experience. Each slide provides a definition, example, or activity for students to...

Is the structure of a clam really as simple as it seems? Young scholars explore the anatomy of the clam in an engaging lesson presentation. The lesson highlights the digestive process of the clam as well as how it moves and what it does...

I bet I can cross the room without having the lights come on. Class members set up an experiment in which they try to determine what materials will mask motion detected by a sensor. Groups predict how materials will interact with...

Every knows that opposites attract! Here's a presentation that uses this background knowledge to explain magnetic fields and forces. The resource also explains the shape of magnetic fields and how to determine the direction of forces.

If you are not part of the solution, then you are part of the precipitate. The presentation covers solutions, suspensions, solubility, dissociation, and acid/base reactions. This is the 19th lesson in a series of 26.

To gain insight into the many different types of habitats, individuals must first get to know their own. Here, scholars explore their school environment, draw a map, compare and contrast their surroundings to larger ones. They then...

Bright and attractive graphics are included to explain how an electric motor works. Along the way, there are a few multiple-choice question slides can be used to pause and evaluate student comprehension. This presentation would be useful...
