Chiral molecules are pairs of molecules with identical chemical composition but mirror-image molecular structures. They are vital in genetics, metabolism, sensory functions, pharmaceuticals, pesticides, biominerals, and the search for life on other planets – in fact, chirality is life! Engaging classroom activities foster students’ visual-spatial thinking, as they investigate chiral molecular structures, model real-world applications of chiral molecules, and explore fascinating techniques for detecting chiral substances.

Standards of Learning: 2010 Chemistry (CH.2, CH.3)

Carbon atoms and hydrocarbon molecules open up the world of the very small to students. Research into carbon nanotubes, buckyballs, and methyl coatings show us some of the amazing properties of this common element. Students will build models and practice with three-dimensional pictures of molecules to develop an understanding of bonding and molecular geometry in nanoparticles.

How does the design of the crumple zone of a car maximize safety and minimize damage during a crash? During this inquiry-based lesson, students will utilize their creativity and knowledge of force, mass, acceleration, impact, and momentum to design and test the crumple zones on remote control cars. Students will use video and measurements taken with probes during car crashes to analyze their designs.

Standards of Learning: 2010 Chemistry (CH.1, CH.3, CH.4); Physics (PH.1, PH.3, PH.4)

Salt water fuel cells provide clean energy transfer, green technology, carbon footprint reduction. Students will investigate MgO fuel cells as a redox reaction using a saltwater electrolytic cell by building and powering a saltwater fuel cell car. Students will need calculators and a basic understanding of chemical reactions; stoichiometric math will be reviewed.

Room Requirement: An open space to run cars is necessary.

Standards of Learning: 2010 Chemistry (CH.2); 2010 Physics (PH.12)

Fireworks, neon signs, and LEDs produce an array of beautiful colored light. Amazingly, the light emitted is due to the movement of excited electrons. In this lesson, students will conduct hands-on, inquiry-based investigations using LED lights, gas discharge tubes, and probeware that will guide them through the structure of atoms, properties of matter, periodic trends, and the fundamentals of Quantum Mechanics. Students will also discover how the knowledge and application of Quantum Mechanics and nanotechnology are used in many of the products we use every day.
