This is a lesson about using light to identify the composition of an object. Learners will use a spectrograph to gather data about light sources. Using the data they’ve collected, students are able to make comparisons between different light... (View More) sources and make conjectures about the composition of a mystery light source. 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. (View Less)
This is a lesson about emission spectra. Learners will look at various light sources (including glow sticks and christmas lights) and make conjectures about their composition. The activity is part of Project Spectra, a science and engineering... (View More) program for middle-high school students, focusing on how light is used to explore the Solar System. (View Less)
In this activity, student teams design and conduct a scientific investigation in which they explore the conditions necessary for life. They conduct observations of environmental conditions both indoor and outdoor, and determine the range of... (View More) variation they see. They compare these data with published temperature data for Earth, Mars, Pluto and Venus. The activity supports inquiry into the real world challenge of searching for life in extreme environments. The resource includes several student data sheets, data table and images, and a teacher's guide. Materials needed for this activity include weather instruments (e.g., thermometers, barometers, anemometers). This is Activity A of two activities in the first module, titled "Temperature variations and habitability," of the resource, "Earth Climate Course: What Determines a Planet's Climate?" The course aims to help students to develop an understanding of our environment as a system of human and natural processes that result in changes that occur over various space and time scales.

This lesson is about data collection. Learners will investigate different methods of sampling in a simulated cleanroom environment. Includes a teacher's guide and students handouts. This lesson 7 of 10 from the Dynamic Design: The Cleanroom module.
This is a lesson about describing meteorites. Learners will observe and describe physical characteristics of an edible sample in preparation for describing rock or meteorite samples. They will work cooperatively in a team setting and use both oral... (View More) and written communication skills. Objectives, activities, vocabulary words, and experimental extensions are included. This is lesson 8 of 19 in Exploring Meteorite Mysteries. (View Less)
