Water pollution is everywhere, and pollutants range from oil to fertilizers. Bring the concept to life by demonstrating the difficulties in getting particular pollutants out of water.

A dozen years after a great plague wipes out the majority of Earth's civilization, a group of scientists joins together to fight infectious diseases. Scholars join the training mission and learn about viruses, bacteria, pathogens and...

Students explain the difficulty that paleontologists have in assembling fossil bones. Hard cookies are used to simulate dinosaur bones/fossils. They research the Apatosaurus and discuss paleontology.

Many people know about chemical pollution, but are all chemicals bad? The third unit in a series of six addresses chemicals common in everyday life. Scholars learn about the chemicals found in their own homes, chemical safety, and...

Getting a ship into orbit isn't rocket science. Oh, wait...that's exactly what it is! Learn the basics of the concepts of thrust, launch angle, and gravitational pull in this fun and progressively challenging game.

Check out a resource that's erupting with engaging material! Earth science scholars discover how igneous rocks form in a well-rounded interactive. They manipulate the cooling time of lava to watch crystals form, learn visual...

Sex-linked traits indicate a gene's location on a specific chromosome. Scholars learn about sex-linked traits and the specifics behind color blindness in the videos. Then they complete the online interactive to apply their knowledge...

An outbreak of malaria requires your help to stop its spread. To discover the pathogen that causes malaria and multiple ways to fight the illness scholars play games, answer short quizzes, and learn scientific concepts with the fourth...

Interactive emphasizes understanding magnitude of momentum vectors depends upon mass and velocity, while the direction of the vector only relates to the direction of movement. As part of the larger series on momentum and collision, three...

Learners use podcasting and iPods to take tests rather than reading. In this podcasting lesson plan, students learn how to use a podcast rather than have a test read to them.

Learn about wastewater and recycled water with a science reading activity. After learners finish a two-page passage about conserving the water supply, they answer six comprehension questions about what they have read.

General chemistry class members engage in a mini-unit on mole conversions. Through nine lab activites with varying degrees of difficulty, they practice measuring mass and volume, molar calculations, and stoichiometry. Terrific...

What do we do when a dive is too dangerous for humans to accomplish? Send in the robots! Middle school scientists get acquainted with several different models of submersible robots in the second activity of six from NOAA. Lab groups then...

How much negative feedback does a body get daily? The interactive walks through one negative feedback loop, increasing body temperature. Then it challenges scholars to relate this to mechanical feedback loops and disorders that prevent...

Ethanol, a grain alcohol, reduces emissions and conserves petroleum when mixed into gasoline. Four puzzles challenge pupils to match alcohols to their structural formulas, types of alcohol, and full oxidation products. Each puzzle...

Scientists call ions with a negative charge anions. Scholars work through one matching puzzle and four logic puzzles reviewing the chemical formulas for anion ions. Each level increases in difficulty and solidifies the concept in pupils'...

Scientists call a molecule that contains a nitrogen atom that behaves as a base an amine. Four puzzles, related to amines and similar compounds, challenge scholars to prove their knowledge. After passing each puzzle, the next increases...

With Earth Day quickly approaching, as well as many science fairs, why not challenge your class to investigate geothermal energy or other renewable energy resources? There are five driving questions explored in depth here, as well as...

Ninth graders set up a scale model of the solar system using the same scale for distance and diameter. They calculate scale distances and sizes for modeling the solar system and relate actual distances to difficulties in discovering and...

Explore the harsh climate of Antarctica and its wildlife. Participate in experiments to determine how humans survive in the continent's climate, and address the difficulties faced by scientists.

What are characteristics of a planet? With this plan, learners investigate the characteristics of the planets in our solar system. They gather research of the nine planets by using the Internet and other research tools. Then they create...

Learners explore atomic measurement in the first activity in a series of 36. Through readings, activities, and questions, classes review standard SI units, learn about Avogadro's constant, and use it to help them calculate moles. They...
