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 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. Activities include constructing capacitors from common materials, comparing the energy storage characteristics of capacitors and batteries, and modeling regenerative braking. 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.
Soaking Up Some Rays: New Developments in Solar Energy (Science 6, Physical Science)
Standards of Learning: 2010 Science (6.1, 6.4); 2010 Physical Science (PS.1, PS. 2, PS.6, PS.9)
New materials and technologies are revitalizing the Solar Energy industry, which utilizes the physical and chemical properties of matter and behavior of light to transfer light energy into usable electrical energy. Students will design and conduct a hands-on evaluation of conventional and new technology solar cells, focusing on the efficiency of the energy transformations that make practical the capture of the limitless energy of the sun as a source of alternate energy.
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.
