Battling for Oxygen

Working in groups, learners model the continuous destruction and creation of ozone (O3) molecules, which occur in the ozone layer. Some learners act as ultraviolet (UV) light and break apart gumdrop and toothpick models of ozone molecules into oxygen molecules and atoms. Meanwhile, other learners assemble ozone molecules from the oxygen molecules and atoms. In a second round, learners model the situation when pollutants such as chlorofluorocarbons (CFCs) are present. In subsequent rounds, the amount of CFCs changes according to historical data, and learners can see what happens to the proportion of ozone and oxygen in the ozone layer over time. Resource contains vocabulary definitions and suggestions for assessment, extensions, and scaling for different levels of learners. (less)

This site from SERC's Starting Point presents sample Gallery Walk questions about the composition of the atmosphere. These questions encourage students to examine atmospheric and greenhouse gases, human influences on climate change, proposed new products to minimize UV exposure, and ways people currently protect themselves from UV exposure. The questions are organized according to the cognitive level at which students are engaged, using Bloom's Taxonomy. (less)

This NASA-created web site introduces electromagnetic waves and their behaviors to secondary learners. Each region of the spectrum is described, illustrated, and accompanied by video clips. Within each section, the authors explore the relationship between wavelength and wave type and provide information about how scientists detect the various waves and collect images of their emissions. Don't miss the link to NASA's <i>Tour of the Electromagnetic Spectrum</i>, a free set of 24 posters, which can be viewed online or printed for the classroom. This tutorial is part of NASA's <i>Mission: Science</i> website. (less)

Melts in Your Bag, Not in Your Hand

In this activity, learners use chocolate to explore how the Sun transfers heat to the Earth through radiation. Learners compare the melting rate between chocolate left in the sunshine and chocolate left in the shade outside for twenty minutes on a hot sunny day. Use this demonstration to introduce learners to solar radiation as well as the importance of summer safety and sun protection. Although this works best on a hot sunny day, this activity can be adapted for indoor use. (less)

Students design and build prototypes for protective eyewear. They choose different activities or sports that require protective eyewear and design a device for that particular use. Students learn about the many ways in which the eyes can be damaged and how engineers incorporate different features and materials into eyewear designs to best protect the eyes. (less)
