Data can travel on light waves ... who knew!?! Pupils explore the idea of using light waves to transmit data through space. They then build their own boards that detect a specific wavelength of light.

Class members discover how mathematics can quantify the behavior of light waves with the fourth installment of a seven-part series that teaches future engineers about equations related to refraction, including the equation to...

After investigating visible light and the electromagnetic spectrum students explain the concept that light can be considered an electromagnetic wave. They give two examples of how engineers use electromagnetic waves, and describe how...

How does the color of the sky change from blue to reds and oranges to black? An illuminating lesson explains how light travels through different mediums using the sun's light as an example. By examining diagrams and illustrations, pupils...

Many types of cancer treatments now depend on nanotechnology—a big "little" discovery. Scholars begin by removing "malignant" tissue from simulated brains, one using fluorescent markers thanks to nanotechnology and one without. This...

What do physicists and musicians have in common? A lot more than you might think. After first viewing a slide show presentation and completing a series of skills practice worksheets on the physics of light, sound, and...

Make sound visible with an activity that provides directions for how to build a vocal visualizer meant to create light patterns. Making noise into the visualizer causes a mirror to vibrate, reflecting a laser beam, and creating...

Zero in on an interesting resource involving radar technology. Groups construct a radar sensing unit and learn to calibrate the system. Using the radar system and the Pythagorean Theorem, they calculate distances between objects.

With a little light and a lot of time, you can create some amazing images. This NASA-related task instructs pupils to build a pinhole camera. The lesson provides suggestions for different pictures to try with the pinhole camera...

Take the class over the rainbow. Pairs or small groups follow directions to create a spectrograph. The pupils measure the angles formed by the different colors of the spectrum along with calculating the lengths formed by the spectrum and...

How can nanoparticles be used in the battle against skin cancer. Class members take on the question as they gather information about electromagnetic radiation, specifically ultraviolet radiation. Pupils learn about the mathematical...

I bet I can cross the room without having the lights come on. Class members set up an experiment in which they try to determine what materials will mask motion detected by a sensor. Groups predict how materials will interact with...

Introduce teams to quantum dot solutions with an activity that has them expose solutions to a blacklight, observe the colors, and take measurements. Groups graph the data and analyze the dependence between particle size and...

In this space science worksheet, students read an informative passage about radio waves and the possibility of sending messages in space. The passage describes a "Sounds of Earth" record on the Voyager satellite which contains messages...

A bit optional. How do computers transmit in the real world? Pupils research a device that is used in transmitting bits, then individuals create a poster that presents the information they have learned about their device. 

STEM scholars investigate sound attenuation by conducting an experiment in which they compare the farthest distance that they can hear a sound with and without ear protection.

Investigate the procedure for developing computer chips! Learners use solar print paper to create both positive and negative images. They observe the effects of single and multiple exposures and compare results.

Introducing ... the aerogel. The first of a two-installment series teaches young engineers about the properties and uses of aerogels. A PowerPoint presentation provides information about this unique material to help solidify the concept.

Youngsters examine resource maps to find out which states are using solar and wind power and discuss as a class various other renewable energy sources. They use a provided data table to record pros and cons to each technology, build and...

Students examine how a community works together to protect them from fire. They work together to design a functional tool that could be helpful in fighting fires. They share their tool with the class.

Young scholars participate in a role play in which they use simple machines to do the work of retrieving their sibling from a tree which lost its ladder. They investigate how work is accomplished when an object moves in the direction of...

Students examine the concepts of forces and motion. They work together to design protective devices for their egg rovers as they are dropped from a specific height. They record their observations and discuss.

In this comprehension worksheet, students read a story and answer the six multiple choice questions that follow. They identify the longest bridge in the world, what happened during construction, and what possible dangers to the bridge...

Students identify the challenges encountered by astronauts in operating a planetary rover. In this space science lesson, students create a rover using their team members. They follow a command sequence from the driver and navigate...
