Population Biology
The carrying capacity of an environment varies based on the organisms that live there. Using a virtual lab simulation, scholars test two protists living in their own environments and a third environment where both protists live. They...

Electrolysis of Water
Young scientists know that water is H2O, but can they prove it? Through a simple electrolysis of water demonstration, scholars see the two gases produced as a result of a chemical reaction. Because this reaction doesn't happen...

Preparation and Combustion of Biodiesel
The United States is the world's largest producer of biofuel. During an in-class investigation, young scientists produce their own biodiesel. They burn a sample of it to determine the heat of combustion. Then they discuss the results...

Mud is Mud...or is it?
We know that the type of soil varies by location, but does the seafloor sediment also vary, or is it all the same? Scholars compare photos of the seafloor from two different locations: the Savannah Scarp and the Charleston Bump. Through...

Lost City Chemistry Detectives
In 1977, scientists discovered hot springs in the middle of deep, cold ocean waters near the Galapagos Islands. Scholars research the chemical reactions that explain what scientists found at the Lost City. A discussion connects many...

I Can't Breathe!
The Gulf of Mexico dead zone, an area of low oxygen that kills marine life, costs the United States $82 million every year. Young scientists research anoxic ocean environments then come up with a hypothesis for the cause of the Gulf of...

The Intertropical Convergence Zone
Young scientists know it is hotter along the equator, but why is it also rainier? Through the process of completing two experiments and a worksheet, scholars discover the answer is the intertropical convergence zone. First, they...

Energy Content of Foods
Why do athletes load up on carbohydrates the evening before a competition? The lesson plan helps answer this question as it relates the type of food to the amount of energy it contains. After a discussion, scholars perform an experiment...

What's So Special about Bottled Drinking Water?
Is artesian water designed to be better, or is it just from wells similar to those in the city of Artesium? This experiment looks at many different types of bottled waters, including artesian. Using a soap mixture, scholars test to see...

Fibers, Dyes, and the Environment
Nanofibers can be made through electrospinning or force spinning in order to reduce the negative impact on the environment. Pupils study the role of fibers and dye on the environment through a series of five hands-on activities. Then,...
LABScI
Harmonic Motion: Pendulum Lab
Several times throughout history, groups of soldiers marching in rhythm across a suspension bridge have caused it to collapse. Scholars experiment with pendulums, resonance, and force to determine why this would happen. First, pupils...

Shedding a "Little" Light on Cancer Surgery
Many types of cancer treatments now depend on nanotechnology—a big "little" discovery. Scholars begin by removing "malignant" tissue from simulated brains, one using fluorescent markers thanks to nanotechnology and one without. This...

The Tide is High, but I’m Holding On… Using ICESat Data to Investigate Sea Level Rise
Based on the rate of melting observed from 2003-2007 in Greenland, it would take less than 10 minutes to fill the Dallas Cowboys' Stadium. The 17th lesson in a series of 21 has scholars use the ICESat data to understand the ice mass...

Virtual Fetal Pig Dissection
Pigs and humans have the same metabolism level and similar organs and systems, which is why they are often used in scientific laboratories. This worthy virtual dissection of a fetal pig divides into eight chapters: anatomical references,...

Projectile Motion
Have you ever wanted to shoot someone out of a canon? This simulation gives you that chance! In addition to a human, you can shoot a car, a piano, a cannon ball, and many other items. Scholars set the angle, initial speed, mass, air...

Ohm's Law
Why did Mr. Ohm marry Mrs. Ohm? He couldn't resistor. An electrifying simulation allows scholars to control both voltage and resistance in order to see the current change. The formula is displayed and as you increase one variable, it...
PHET
My Solar System
Orbit diagrams appear to be a work of mathematical art. The simulation helps scholars build their own systems of planets, stars, moons, etc., to observe their orbits. By altering their positions, velocities, and masses, a variety of...

Hooke's Law
Everything from pens to cars use springs — some are just on a larger scale! An interactive simulation encourages pupils to stretch and compress springs while observing the changes to force, displacement, and potential energy. Then they...

Is It Getting Hot in Here, or Is It Just Me?
Currently, only 2.1% of global warming is felt on continents, while over 93% is felt in the oceans. The fourth lesson in the series of 21 on global warming is composed of three activities that build off one another. In the first...
PHET
Masses and Springs
Have you ever stretched out a Slinkie so much it wouldn't go back to its original shape? Slinkies, like all springs, follow Hooke's Law. A simulation uses springs and masses to demonstrate kinetic, potential, and thermal energy. It...
PHET
Gravity And Orbits
Have you ever wanted to turn off gravity? This simulation allows learners to do just that in addition to altering other variables. Scholars can move the sun, Earth, moon, and space station to see how distance affects gravitational pull....

It's A Bird...It's A Plane...It's...CARBON!
An interesting lesson takes pupils on a trip through the carbon cycle. A reading passage allows scholars to take notes and make choices about what happens to the carbon on its journey. This third lesson in a series of 21 discusses...

Forces and Motion: Basics
How is tug of war related to pushing a refrigerator? Here's a simulation connects these two activities with Newton's First Law of Motion. Four different simulations allow scholars to explore net force with tug of war, motion with pushing...

Conceptualizing Module III
Many researchers focus on one impact of climate change in isolation, but researchers gain a global perspective when they come together. A timely lesson teaches scholars about the projected impacts of global temperature increases. Then...
