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...

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...

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...

If you don't get along with someone, it's said that the two of you are like oil and water. Why is this? Explore the phenomenon and explain the phrase in one resource! Science superstars first observe samples of oil and water together....

What does it look like when two atoms bond? Mol-e-COOL! Aspiring chemists observe the interaction between two atoms forming a bond in an easy-to-use interactive. Individuals move atoms closer together and observe changes in attraction...

Is your stoichiometry lesson plan just not adding up? Incorporate an exciting interactive to balance things out! Chemistry scholars manipulate the number of molecules added to the reaction vessel, then observe as bonds form and break as...

Ahh, the rules of attraction...intermolecular attraction! Introduce your chemistry crew to the other forces that influence the behavior of atoms and molecules alike with a simple interactive. Pupils push and pull polar and non-polar...

Why does like dissolve like? While in many cases opposites attract, the same cannot be said for chemistry! Solution scholars take an up-close look at the dissolving process with a customizable interactive. The resource allows users to...

What happens to substances when they dissolve in water? Young scientists investigate the dissolving process with a colorful interactive. The resource illustrates changes in potential energy as solute particles interact with water...

Breaking up is hard, especially with a third part involved! Watch as molecules of hydrogen, oxygen, and nitrogen try to keep it together as a neutral third atom bombards them. Users control the reactive molecules and the velocity of the...

Have you reached your breaking point in looking for great resources that illustrate bond energy? Demonstrate the potential energy changes that occur when polar and non-polar bonds are broken with a stimulating simulation. Pupils pull on...

So how does the carbon cycle work? Kids participate in a hands-on activity that allows them to understand the chemistry behind climate change and global warming. They act out the process of photosynthesis by labeling themselves as...

Aquapores allow water to travel through cell membranes while keeping other molecules out. The animation offers an up-close look at these parts of the cell membrane. It explores multiple vantage points and shows the importance of these...

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...

Students explore liquids and solids by conducting in class experiments. In this matter lesson, students define the properties of matter and how heat can change those properties. Students experiment with heating objects such as butter and...

Pupils explore matter by conducting an in-class experiment. They experiment with water's various forms by melting and freezing water, identifying its new shape. These observations are recorded to supplement later discussion. They also...

Young scientists explore Earth elements by conducting an experiment. They define water vocabulary terms such as condensation and precipitation. In addition, they conduct a water experiment in which they build a terrarium, so they can...

Students demonstrate the components of methane molecules to discover their effects on the atmosphere. Students role-play as four hydrogen atoms and one carbon atom linked together to make a methane molecule. Students act as the molecule...

Students pretend they are water droplets traveling through the water cycle. Using their text, they discover the steps in the cycle and the different paths water can take. They write a report about their journey through the water cycle...

Students act out the cycling of nitrogen through the environment. In this nutrient cycle lesson, students role play as nitrogen atoms traveling through the nitrogen cycle. They travel to stations and roll dice to determine the...

Ninth graders explain how a scanning tunneling microscope works. In this chemistry lesson, 9th graders construct atomic models and simulate how their images appear under the STM. They discuss the limitations of their atomic model.

Students explore online tutorial on polymers. In this chemistry lesson, they create two polymers in the lab and compare their properties. They write a sales letter about their new and improved polymer product.

Learners explore the energy changes from a liquid to a solid. They model the arrangement of a solid and the change in states due to changes in energy using desks and chairs. Assessment questions are provided in lesson plan.

Students explore physics by conducting a class experiment. In this gravitational force lesson, students define several scientific terms associated with force. Students utilize a styrofoam cup and marbles to simulate a satellite crashing...
