This activity introduces learners to the visible portion of electromagnetic spectrum. A visible spectrum is projected in the classroom using a diffraction grating and learners reproduce it using colored pencils. Filters are also used to block... (View More)

In this activity, students build an obstacle course for a flashlight beam using file cards, hole punch, clay, and observe that light travels in a straight line and demonstrate the concept of light extinction. The resource is part of the teacher's... (View More)

In this problem-based learning activity, students explore the economic advantages and tradeoffs associated with grazing on public lands. Students calculate the fees paid by a rancher to graze cattle on Bureau of Land Management (BLM) property, and... (View More)

Slinky toys are used to demonstrate how primary (P) and secondary (S) waves travel in earthquakes. The resource is part of the teacher's guide accompanying the video, NASA SCI Files: The Case of the Shaky Quake. Lesson objectives supported by the... (View More)

In this activity, students examine everyday objects with a flashlight and determine if they are transparent, translucent, or opaque. Common household materials such as wax paper, plastic wrap, aluminum foil, tissue, and food coloring are required.... (View More)

In this activity, learners will explore the properties of color filters and filter bandpass by observing light sources using diffraction grating and color filters and create a graph of percent transmission versus wavelength to characterize the... (View More)

In this kinesthetic game, student learn about light reflection. Teams line up with a series of mirrors and race to as they transfer a beam of light from one mirror to another as quickly as they can. A flashlight and 4 or 5 handheld mirrors are... (View More)

Students use a variety of utensil "beaks" to represent the feeding adaptations of different kinds of finches. Foraging on a lawn environment, students search for different kinds of food (yarn, beans and pasta) each having three color variants. Over... (View More)

Materials Cost: $1 - $5 per group of students

In this demonstration, students learn about the physical process of liquification and how it causes the ground to become unstable during an earthquake. Required materials include a plastic tub, sand, water, a brick and a rubber mallet. The resource... (View More)

This is an activity about auroras. Learners will use images from the IMAGE (Imager for Magnetopause-to-Aurora Global Exploration) satellite and measure the diameter of aurora ovals to identify if there is a correlation between severe magnetic storms... (View More)
