Nondestructive Evaluation (NDE) is the process of evaluating materials to detect and measure the presence of defects without causing damage to the material being tested. In this lesson, middle and high school students are introduced to NDE,... (View More)

Learners design and build an airbag system that can safely land an egg dropped from a height of 3' onto the floor. This resource includes a challenge video, leader notes, and handouts. Two supplemental videos are included: 1) An airbag landing... (View More)

Learners design and build a device that can take a core sample from a potato. This resource includes a challenge video, leader notes, and handouts. Two supplemental videos are included: 1) NASA's Curiosity rover drilling into a rock on Mars and... (View More)

In this hands-on engineering challenge, learners design, build, and improve a model that allows a moving object to change direction using an invisible force. Mimicking the gravity-assisted travel of the New Horizons spacecraft, learners roll a steel... (View More)

Learners design and build a device that can pass above a surface and detect magnetic fields. This resource includes a challenge video, leader notes, and handouts. Two supplemental videos are included: 1) Measuring Magnetic Fields and 2) NASA flight... (View More)

Learners design and build a robotic arm that can lift a cup off a table. This resource includes a challenge video, leader notes, and handouts. Two supplemental videos are also included: 1) NASA's Curiosity rover using its robotic arm to probe the... (View More)

Students will test various materials to determine if any can shield their "magnetometer" (compass) from an external magnetic field using their own experimental design. If no suitable material is available, they will devise another method to protect... (View More)

Using water to represent the atmosphere and milk droplets to represent aerosols, students make predictions and conduct investigations to discover how different aerosol concentrations affect atmospheric color and visibility. This lesson is one of... (View More)

Through the use of prisms and glue sticks, this activity introduces students to a fundamental property of light: white light is made up of colors representing different wavelengths. Students use the results of the activity to explain the variation... (View More)

This afterschool curriculum includes six lessons plus supplementary materials (e.g., videos, PowerPoint presentations, and images) that explore how light from the electromagnetic spectrum is used as a tool for learning about the Sun. The curriculum... (View More)
