In this activity about spectroscopy, learners build a spectroscope, learn about graphing spectra, and then identify elements in gas tubes using their spectra. The activity concludes as learners graph the spectra of different materials. Essential... (View More) materials required for this activity include spectrum light tubes, the power source for spectrum light tubes, and diffraction grating material. (View Less)
This is an activity about seasons. Learners begin by brainstorming a list of activities and events that occur in each season. Next, learners perform an experiment by comparing the temperature on thermometers left under a lamp for different lengths... (View More) of time to illustrate that Earth heats more when the Sun is in the sky longer. (View Less)
This is an activity about the measurement of time. Learners model the rotation of Earth over one day by holding a flashlight for the Sun and a blow up globe, and record their observations. Then, they use those observations to create devices that... (View More) will track time and test their devices outside. This final part of this activity requires access to a sunny outdoor location for an extended period of time so learners can test their time measurement devices. (View Less)
This is an activity about what individuals already know about the Sun. Learners will brainstorm and share with the group their prior knowledge about the Sun. This is Activity 1 of the Sun As a Star afterschool curriculum.
This is an activity about magnetic induction. Learners will induce a flow of electricity in a wire using a moving bar magnet and measure this flow using a galvanometer, or Am meter. Through discussion, this activity can then be related to magnetic... (View More) fields in nature. This activity requires use of a galvanometer, bar or cow magnet, and wire. This is the fifth lesson in the second session of the Exploring Magnetism teacher guide. (View Less)
In this activity, students begin learning about archaeoastronomy much as the first skywatchers began learning about the sky: by observing and wondering. Students observe photographs and drawings of petroglyphs, pictographs, and natural and... (View More) human-made structures believed to be ancient observatories or of relevance to ancient astronomies and astronomers. They discuss and record observations (I notice…) and questions (I wonder…) on chart paper. This activity, which is the first in the Ancient Eyes Look to the Skies curriculum, allows teachers to discover students' prior experience and knowledge, thus helping them personalize the other activities in the curriculum for their classes.
