Building Green in the 21st Century (Science 6, Physical Science)
Standards of Learning: 2010 Science (6.1, 6.2); 2010 Physical Science (PS.1, PS.6, PS.7, PS.9)
The key to saving precious energy resources and reducing carbon emissions is efficiency in energy transfer. In this lesson, students will work in groups to explore concepts of energy transfer and efficiency. Additionally, students will examine new building materials that promise to save significant energy resources while producing less waste and less carbon dioxide for global warming.
Crunch This! (Physical Science)
Standards of Learning: 2010 Physical Science (PS.1, PS.5, PS.6)
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 as they develop knowledge of force, mass, acceleration, impact, and momentum to as they design and test crumple zones on cars. Students will use video and measurements taken with probes during car crashes to analyze their designs.
I'm Stuffed: Ultracapacitors and Energy Storage (Science 6, Physical Science)
Standards of Learning: 2010 Science (6.1, 6.2, 6.9); 2010 Physical Science (PS.1, PS.6, PS.10)
Unlike the fossil fuel resources they replace, many alternate energy sources, like wind power and solar, are not always available. To make them practical, they require some way to store energy for use when the power is needed but is not being generated. Ultracapacitors offer a new alternative to rechargeable batteries and utilize nanotechnology to increase the overall efficiency of the systems. Students will construct capacitors from common materials and compare the energy storage characteristics of capacitors and batteries. Students will discover how nanotechnology allows small devices to pack a big punch!
Let’s Get Trendy: Exploring the Periodic Table (Physical Science)
Standards of Learning: 2010 Physical Science: PS.3, PS.4
The periodic table was designed for predictability utilizing the trends of the atomic structure of the elements. During this lesson students will participate in an activity that will enhance their understanding of the design of the periodic table. They will use this knowledge to construct atoms as well as illustrate the bonding that occurs during chemical reactions.
Music Makers (Physical Science)
Standards of Learning: 2010 Physical Science: PS.8
Music is perhaps the most basic and universal form of communication and expression. In this lesson, students will explore many aspects of what it takes to make music with one of the most popular instruments, the guitar. The lesson addresses the science behind stringed instruments, using various experiments and engineering activities to challenge students to become active participants, rather than passive listeners.
Waste Not, Want Not: Energy Transformations in the Classroom (Physical Science)
Standards of Learning: 2010 Physical Science: PS.5, PS.6, PS.7
Our technological society uses vast amounts of energy for transportation, manufacturing, and controlling the environment in our buildings, among other things. As energy is converted from one form to another, much of it is wasted as heat, vibration, sound, or in other ways. During this lesson, students will work with partners at multiple stations to investigate energy harvesting, ways that wasted energy can be captured and put to use.
