This resources identifies best practices for giving presentations or talks in elementary classrooms and was developed to help scientists and engineers who have been asked to visit an elementary classroom. It provides helpful suggestions before, during, and after the presentation, as well questions for the teacher (e.g., what content do you want me to cover, what have students already learned about this content?).

This is a lesson about planetary atmospheres. Learners will interpret real spectral graphs from missions to determine what some of Earth, Venus, and Mars’ atmosphere is composed of and then mathematically compare the amount of the greenhouse gas, CO2, on the planets Venus, Earth, and Mars in order to determine which has the most. Students brainstorm to figure out what things, along with greenhouse gases, can affect a planet’s temperature. The activity is part of Project Spectra, a science and engineering program for middle-high school students, focusing on how light is used to explore the Solar System.

In this activity, students examine a photo and map of Manhattan, New York, to determine the date the photo was taken. The activity provides opportunities for discussing seasons, equinoxes, and the apparent position of the Sun throughout the year. Links to additional information are embedded in the text.

In this activity, students work in groups to create a presentation that illustrates the meaning of the statement "To make an apple pie from scratch you must first invent the universe." Students pick an element that can be found in apple pie and trace its evolutionary history back to the birth of the universe itself. They also share their vision of the environment in which that element may find itself 5 or so billion years from now after the Earth is long gone. Presentations are intended to demonstrate student understanding of the origins and life cycle of matter, so this activity is appropriate as a conclusion to a unit. This activity is part of the "What is Your Cosmic Connection to the Elements" information and activity booklet. The booklet includes teacher notes, grading guide and student handouts.

This is a lesson about visual spectra. Learners will explore different ways of displaying visual spectra, including colored "barcode" spectra, like those produced by a diffraction grating, and line plots displaying intensity versus color, or wavelength. Students learn that a diffraction grating acts like a prism, bending light into its component colors. The activity is part of Project Spectra, a science and engineering program for middle-high school students, focusing on how light is used to explore the Solar System.

In this video segment adapted from NOVA, watch residents of the Peruvian Andes build a suspension bridge made entirely of grass. The ancient Inca were a textile society and thus skilled in working with natural fibers including alpaca and cotton. Still, it might surprise people today that their solution to crossing the canyons and gorges of their mountainous empire featured another fibrous material: grass. When you consider how they built a simple suspension bridge, you'll realize that not only was this a practical solution, it was also a safe one. In this video segment adapted from NOVA, watch residents of the Peruvian Andes as they build a traditional and functioning grass bridge the likes of which enabled the ancient Inca people to flourish for several hundred years. Grades 3-12.
