I'm so cool! No, you're exothermic. This thermodynamics lab unit includes an introduction, teacher demonstrations, six labs that students rotate through each class day, homework assignments, application of knowledge, and...

Though the walrus spends roughly one third of its time on land, it eats organisms that live on the bottom of the ocean. The first in a series of five, the lesson uses a variety of plant and animal cards to have scholars build an arctic...

The first golf balls were made of wood and would only last for a few games. Modern golf balls last a lot longer but they don't float. The presentation provides the directions for a lab to determine the minimum amount of salt needed to...

How do greenhouse gases impact temperature? Have your classes use the interactive software to explore different concentrations of greenhouse gases and their effect on climate. Learners can recreate different atmospheric concentrations...

Climate change isn't just about a warming planet; it will affect humans' health, spread of disease, changes in heat waves and droughts, and changes in storms and wildfires. Participants explore global climate change through discussions...

The sound waves of thunder are made when lightning very quickly heats the air surrounding it, expanding faster than the speed of sound. Learners explore waves through their own movement of string or set waves to constantly oscillate....

Beer's Law can be used to measure the concentration of certain compounds in samples of food. In the concentration simulation, particpants change and measure the concentration of different solutions by manipulating various types of...

Just like the old saying goes, "What goes in must come out." This simulation allows pupils to balance chemical equations. The introduction gives three examples before scholars switch to game mode, pick their level, and continue to...

Through the analysis of paper chromatography to separate ink from the pen found at the crime scene, learners analyze the different stains and through calculations determine the thief. 

As of April, 2016, more than 28,000 suspected cases of Ebola were recorded in Western Africa with over 11,000 human deaths. Classes discuss the Ebola virus outbreak in 2014 and then groups develop an action plan based on...

Cancerous tissues contain more water than normal tissue, which causes the cancerous tissue to resonate longer on the screen and be seen. High school learners can see how MRIs detect tumors in someone's head. Radio transmitters emit their...

Ionic bonds form from electrostatic energy, allowing for higher conductivity than those seen in covalent bonds. In the simulation, learners add sugar and salt to water and see the effects on concentration and conductivity of their...

Water is the only molecule on Earth that can naturally exist in all three states of matter. The interactive simulation shows different molecules changing states of matter with the addition or removal of heat. Learners then see how...

Did you know when you mix the reactants sulfur, tungsten, and silver, you get the products SWAg? The simulation begins with making sandwiches, to show pupils reactants and products of something familiar. They then can make water,...

Uranium 235 has a half-life of over 700 million years and is the fuel used in the atomic bomb dropped on Hiroshima, Japan. Pupils see the half-lives and decay rates of Carbon-14 and Uranium-238. They also take measurements of these two...

The shape of a molecule is determined by the arrangement of atoms around the central atom and lone pairs of electrons. Scholars build models of molecules using single, double, and triple bonds. They can then see real molecules bond...

Some isotopes are unstable, or radioactive, meaning they will decay over time and turn into another isotope or stable element. In the interactive simulation, participants manipulate elements to create isotopes and gather information....

In molecules, bonds rotate about the nucleus due to the repulsion of subatomic particles. In a simulation, learners manipulate the bonds of a molecule to meet the atoms' needs. They can then see the specific molecular shapes of five...

How many different molecules can you build? In a simulation, learners make molecules from given atoms. There are numerous collections from which to build three to five molecules from given kits of atoms. Scholars can also view their...

Learners, through watching a simulation, can manipulate various characteristics of different solutions focusing on acid-base solutions where pH, strength of solution, and concentration may be changed. Views may be at the molecular...

Have you ever tried to light ice on fire? With methane hydrate, you can do exactly that. The ice forms with methane inside so it looks like ice, but is able to burn. The lesson uses group research and a hands-on activity to help scholars...

The U.S. produced enough wind energy in 2015 to power all of the homes in Alaska, California, Delaware, the District of Columbia, Hawaii, Idaho, Maine, Montana, Nebraska, New Hampshire, North Dakota, Rhode Island, South Dakota, and...

After a discussion of chemical reactions and electricity, scholars break into groups and follow a scripted activity to discover if fruit can power a clock. After a concluding discussion, the class a presented with a challenge.

Warm up to the idea of solar energy. A lesson includes three activities that challenge scholars to apply knowledge in new ways. First, they learn to run an alarm clock without a battery by using solar energy. Next, they complete an...
