Water Molecules in Drama
The state of molecules is changing. Young actors and actresses perform the process of phase change in front of the class. They assume the roles of water molecules and, as a group, show how the behavior of the molecules in the solid,...

Water Molecules Can
On its own, this is not an exciting presentation on the properties of the water. It consists only of two slides: the title slide, which informs the viewer that water molecules have hydrogen bonds, and another slide, which lists four...

The Water Cycle
Your class sets up a mini water cycle model to examine the process. Then they watch an animation, following a water molecule through the cycle. A well-developed lab sheet guides learners through the lesson and a PowerPoint presentation...

Drops on a Penny
A helpful worksheet describes an interesting demonstration on the surface tension of water. Learners guess how many drops of water the heads side of a penny will hold. This resource does a great job of describing just how a penny can...

The Marvels of the Molecule
Students experiment with common substances to observe molecular behavior. In this molecular properties lesson, students move through four stations as they try to inflate a balloon inside a bottle, pour water from a jar, and observe how...

Reaction Between Hydrogen and Oxygen Molecules
When molecules of hydrogen and oxygen are combined, how does water form? Science scholars observe changes in kinetic and potential energy during a chemical reaction in an interactive. The resource features easy controls that allow users...

Changing State: Evaporation
Why do experiments require a control? Guide scholars through designing an experiment to see what they can do to evaporate water faster with a lesson that stresses the importance of controlling all variables. The second activity allows...

Molecule Shapes: Basics
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...

Chemical Formulas for Molecules
Newcomers to chemistry compare hydrogen peroxide to water, realizing that the difference of one oxygen atom significantly affects the chemical properties. Other pairs of compounds and their formulas are also examined. A few chemical...

Why Does Water Dissolve Salt?
Individuals explore solubility by modeling how water dissolves salts. They then view a video and compare how well water and alcohol dissolve salts, relating their comparisons to the structure of each molecule.

Why Does Water Dissolve Sugar?
Did you know that if you wait long enough, the M on the outside of an M and M will float to the surface when submerged in water? Learners observe the sugar coating of an M and M while it is dissolving in water. They explain how this...

Molecules in Motion
I heard that oxygen and magnesium were going out and I was like "O Mg." Pupils experiment with adding food coloring to water of various temperatures in order to determine how temperature impacts molecular movement. This is the...
Concord Consortium
Unshared Electrons and the "Bent" Shape
Why is water always so bent out of shape? Scholars investigate the molecular geometry of the water molecule using a 3-D resource. The interactive features options such as rotation and the ability to view electron pairs.

Splitting Water with Electricity
Explore how electricity splits water molecules into hydrogen and oxygen. Learners begin by calculating the voltage necessary to separate the water. They then perform the experiment and measure the ratio of hydrogen and oxygen bubbles.

The Water Cycle
Explore the water cycle with a hands-on earth science activity that prompts pupils to measure the amount of water normally transpired by plants. After they describe the flow of the water cycle and provide examples of how human activities...

Using Modeling to Demonstrate Self-Assembly in Nanotechnology
Do polar opposites attract? After an introduction on the polarity of molecules, pupils are asked to design a self-assembling model using materials with different polarity. The challenge should motivate learners to develop a workable...

Seashore Explorers
There are three separate lessons within this resource that can be used together, or that can each stand alone. In the first, five simple activities allow junior scientists to examine the amazing properties of water. In the second, they...

Mighty Molecules
Students examine a PowerPoint production on molecules. Then they construct their own molecule and define what an atom, molecule, and matter is. They make a H2, HCI, and an H2O molecule. Finally, a drawing to accompany the actual model is...

Investigation: Chemical Models
Science teams make models of four different hydrocarbon compounds that we commonly use for fuel. Then they demonstrate chemical reactions that result when energy is produced. This can be used as an enrichment when your class is studying...
