Students use an on line simulation to produce ammonia using Haber's process. In this Haber's process lesson plan, students use a spreadsheet to manipulate the pressure, temperature and catalysts used in the production of ammonia. Their...

Students simulate radioactive decay and nuclear power using an on line interactive web site. In this on line lesson plan, students monitor radioactive isotopes and record the activity of a particular element as the decay progresses. They...

How does electricity travel through power lines? The simulation demonstrates the how changes in voltage and resistance are related to the distance between power polls and the thickness of the cable. Scholars control three variables in...

Why can we see our reflection in a window but not a brick wall? Young physicists learn the Law of Reflection and various light properties that help them answer this and other questions about reflection. Use the PowerPoint to introduce...

Teams of six to eight players imagine that they are driving in a vehicle and collect balls that represent carbon dioxide emissions based on their different activities. "Greenhouse Gas Guzzler" cards tell teams how many balls to collect...

Not just a simple globe of the moon, this interactive version allows you to choose lighting according to the location of the sun, views from different positions on Earth, and more! Satellite images and topographic data have been combined...

Star light, star bright, first star I see ... wait a minute, where did the star go? Scholars complete a simulation that measures the brightness of a distant star as another object passes in front of it. Learners move the passing...

The earth has a giant magnetic field caused by the liquid iron that constantly moves in the outer core. Scholars explore the magnetic fields of four different planets. The strength and alignment of the poles relates to the implications...

Where did the pH scale come from? Take a deeper look at a most important measure of ion concentration using a simulated physical determination. Young chemists prepare a series of dilutions after determining a dilution factor for the...

When a child lets go of a helium balloon, what happens to it? Does it float all the way to space? The simulator allows pupils to experiment on party balloons and weather balloons under different conditions to see what happens to them in...

Students use an on line website to simulate the effects of light intensity and wavelength on photosynthesis. In this photosynthesis lesson plan, students determine how wavelength of light and intensity of light affect the rate at which...

Earthquakes are really no one's fault. A thorough lesson explains the different types of earthquakes how they happen. Learners interact with the online lesson to simulate earthquakes and examine their results. The lesson is appropriate...

Using a magnifier, mini marine biologists examine the barbules of a bird feather. They swirl the it into a mixture of oil and water and then re-examine the feather. After the activity, discuss how the oily feathers pose a problem to...

The pre-lab portion of the lesson introduces emerging geologists to the various layers that make up Earth. After completing a sheet on the identification of the layers, class members simulate plate boundaries and their...

Dramatize the stars and planets as they become a visual representation of the solar system in this activity. Young astronomers track and simulate various constellations as they orbit the Earth to learn the position and motion of...

You'll feel strongly about this weak acid and base virtual lab! Scholars experiment with the wonders of dissociation constants in a simulated lab environment. The accompanying written work includes buffer preparation, titration curves,...

Who knew that mountain formation could be so entertaining? Leanr how mountains form with a resource on Mount Everest. Activities to guide learning include a simulation, project, videos, coloring activities, and worksheets.

Students examine scientific evidence of changes in the Arctic ice cover. They participate in a simulation of an international conference and debate the relationship between global warming and changes in the arctic ice cover.

High voltage power lines deliver electricity to homes, but each home requires low voltage. How does the energy get converted so it can be used safely? Pupils explore alternating current and transformers through a simulation. They control...

Are the people on the other side of the world standing upside down? Pupils discuss the relationship between movement and position words. The unit explores the concept of reference points through animation, modeling, photography, and...

A truly hands-on and inquiry based learning activity bridges all the lessons in the series together. Beginning with a discussion on average global temperatures, young meteorologists use real-world data to analyze climate trends in order...

Middle schoolers model a watershed and delineate one using topographic maps. In this hydrology lesson, students use aluminum foil to model a landscape and observe how water moves on it. They also observe the features of a topographic map...

Students read from a NASA Web-based textbook, then students demonstrate an understanding of the text by answering questions about the forces on an airplane and their resulting motions.

Get three planes to line up safely. Individuals work through a set of problems to eliminate spacing conflicts between three airplanes in flight. The pupils use their knowledge to change the airplanes' speed or route to meet a...
