They may not look like it, but sponges are living, breathing creatures! A PowerPoint presentation explains the important characteristics of the invertebrate Phylum Porifera, or more commonly known as the sponges. From their body...

Not going into depth on any one topic, this Earth science presentation skims the crust. It touches on the materials that construct the crust and then moves into plate tectonics. This is a useful and colorful note-taking guide for your...

What do physicists and musicians have in common? A lot more than you might think. After first viewing a slide show presentation and completing a series of skills practice worksheets on the physics of light, sound, and...

Take young biologists back to the beginning of life on Earth with this presentation on bacteria. Examining the different classifications of bacteria, this presentation introduces young scientists to the concepts of autotrophs and...

A fifteen-slide presentation helps you teach your young chemists about monomers and polymers. You will find many graphics, some of them colorful, and bullet-point style notes on each slide. Although the presentation is informative,...

Get an in-depth look into erosion and deposition with a 23-slide presentation that details how gravity, water, waves, wind, and glaciers cause changes to the Earth's surface. Each slide consists of detailed images equipped with labels,...

Learn about conduction, convection, and radiation with an illustrative presentation. It includes slides about atmospheric movement and how it affects the climate, solar radiation, and how latent heat can form storms. 

Every region has a renewable resource that can be used to make hydrogen. But, what is hydrogen and why can it be used as an energy source? Find out with a presentation that answers these questions and then discusses where hydrogen is...

After viewing this presentation, students create a complete set of notes to support their learning of DNA replication. Each slide has information on a step in DNA synthesis process. The slides focus primarily on the processes rather than...

A few definitions related to waves open this slide show. Note that the information only covers light waves even though the title mentions sound. Correct the title before using this resource. Another mention is a set of photos of a class...

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...

With this collection of slides, future biologists get to view photographs of protozoans from different phyla. Interspersed with the photos are bullet-style notes listing characteristics of each group. Unfortunately, most of the pictures...

Class members learn how to estimate the total costs involved to design and build a bridge by including design, material, equipment, and labor costs. The activity includes a discussion about the trade-off between cost and aesthetics.

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...

Comparing aluminum and titanium, this PowerPoint gives the physical and chemical properties of each. Illustrations are used to assist in understanding. The notes are succinct, making this information a great model for chemistry or earth...

Introduction your class to famous astronomers with a presentation that also covers Newton's Laws of Gravitation, Kepler's Laws of Planetary Motion, both uniform and nonuniform gravitational fields, and how to calculate the gravitational...

Here's a lesson that just might make your class squirm! Learn about segmented worms in a detailed PowerPoint presentation including the wriggly earthworms young scientists dig up in their backyards. Although seemingly simple creatures,...

Are outer planets just like inner planets? Nope! The outer planets are much more spread apart than the inner planets. An informative PowerPoint presentation shows why this is true as well as facts about the individual planets in the...

Here is a simple PowerPoint to support your lesson on the behavior of light. As you go through the slides, use real examples of dull and shiney materials for your elementary learners to view. Use the torch, sun, lamp, candle, and bulb...

Introduce your class to storage tank failures caused by major storms with an activity that looks at how the concepts of Archimedes' Principle and Pascal's Law affect the storage tanks along the Houston Ship Channel. The background...

"Self-guided Computer Activity" simply means that young chemists read through the slides and take notes about atoms along the way. There is an abundance of text on each slide, making this a comprehensive introduction to atomic structure....

Each of these slides has notes for a teacher to support the activities that are planned for the students. The slides give details and facts about sound waves. Although this slide show delivers useful information about the sound waves,...
