In this lesson, learners will discover how certain snakes (pit-vipers) can find prey using a natural infrared sensor and will extend their understandings by exploring infrared technology applications. The lesson features background information for... (View More)

In this multi-day activity, students use infrared and visible images of animals and sort them into broad categories based upon the learner's own reasoning and observations of the images. Further explorations reveal that warm and cold-blooded animals... (View More)

In this introductory activity, learners investigate and discuss infrared images of various everyday objects, such as toasters, hairdryers, and running water, to learn about infrared imaging. Student questions about the false-color images help guide... (View More)

In this experiment, students create a "lava lamp" - a beaker on a hotplate, and investigate buoyancy, convection and other fluid and thermodynamic properties using ink, water, vegetable oil and Alka-Seltzer tablets. The activity is from PUMAS -... (View More)

In this activity, students devise ways to demonstrate that energy can change from one form to another in accord with the law of conservation of energy. Small appliances, toys, marbles, vinegar and baking soda, simple electrical supplies available... (View More)

In this activity, students are introduced to the concept of remote sensing. In the course of this experiment, students will investigate heat conduction on two surfaces and understand the application of these techniques to spacecraft investigations... (View More)

In this lesson, students are introduced to the electromagnetic spectrum. They observe a demonstration of the visible light spectrum created by a flashlight and a prism, complete an activity sheet where they identify the wavelength that is involved... (View More)

Students are introduced to classification through progressive activities. Initially, the teacher models the task by classifying buttons. Students then devise a classification scheme for paper clips. Subsequent activities use objects brought from... (View More)
