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...

Heat, Temperature, and Conduction
How does heat move from one item to another, even when the items are in different states of matter? Pupils experiment with adding washers to hot water and adding hot washers to room temperature water to observe the heat transfer.

Biological Oceanographic Investigations – Call to Arms
How many simple machines does it take to make a robotic arm? An inquiry-based lesson explores that topic and challenges pupils to build a robotic arm that can stretch, turn, and more. A few questions help guide them in the right...

Importance of Deep-Sea Ecosystems – What Killed the Seeds?
Most drugs used today come from nature, so the discovery of new ecosystems in the deep sea is exciting from a medical perspective. Scholars develop their own bioassay to test germination rates in seeds.

Using Paper Chromatography
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.

Ebola Outbreak
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 research,...

Simplified MRI
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...
PhET
Sugar and Salt Solutions
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...
PhET
States of Matter
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...
PhET
Reactants, Products and Leftovers
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,...

Radioactive Dating Game
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...

Molecule Shapes
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...
PhET
Isotopes and Atomic Mass
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....

Energy Levels, Electrons, and Ionic Boding
Learners see how electrons are transferred in the bonding of NaCl. They then create models of NaCl using styrofoam balls and toothpicks to assist them in explaining the formation of ions and ionic bonding.
American Chemical Society
The Periodic Table and Energy-Level Models
Teach your class to think of electrons as tiny packets of energy that travel in waves. Through a short video and diagram, participants see how electrons are located around the nucleus of an atom. They then get into groups and try to...

Temperature Changes in Dissolving
Alia-Seltzer tablets cause a very obvious chemical change, but do they also cause a temperature change? Each class member explores hot/cold packs, discussing how these temperature changes occur. Groups then design and carry out their own...

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.

Surface Tension
A drop of dew holds a sphere shape even when sitting on a seat thanks to the surface tension of water. Learners observe the phenomena of surface tension in water. Through demonstrations, hands-on activities, and discussions they explore...

How Journalists Minimize Bias
Class members are challenged to write a neutral news story about the events they observe in a short video. After sharing their stories in groups and discussing the different perceptions, the class concludes with a video of journalists...

Confirmation and Other Biases
As the investigation into the reporting of the events in Ferguson, Missouri, continues, class members consider how bias influences perception, how the tendency is to collect evidence that supports preconceived notions. The big idea...

The Impact of Identity
How does identity influence the way people respond to events? That is the central question class members grapple with as they examine a political cartoon, read a vignette by Sandra Cisneros, watch of video of police officers discussing...

Preparing Students for Difficult Converstaitons
Many of the issues facing 21st Century learners are challenging and even discussing these issues can be a challenge. So how do teachers prepare learners for these difficult conversations? How do instructors create a safe classroom where...

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...
