Students explain how telescopes work and how they can contribute to our knowledge of the universe.

Students discuss their perceptions of magnetism and explore the background ideas of magnetism.

Students describe a problem and propose alternative strategies for the solution. They use a model or drawing to visualize the solution to a problem. Students identify alternative factors to be considered when examining possible...

Fourth graders use circles to "home in" on particular spots, showing the ability of scientists to locate unseen objects in space. This activity shows how scientists know certain objects exist in space due to the forces exerted by...

Students investigate the Transit of Venus and create and produce a public service commercial promoting the Transit of Venus and providing information about its safe viewing.

Students investigate the uses and purpose of the Hubble telescope. They create a model of the telescope and conduct research about the history behind the invention of it. Students use the information in order to create a context for the...

Students using a slide made out of aluminum foil and pin holes observe visible light.

Students using experiments try to demonstrate how observations can be affected by the cycles of night and day.

Students using different experiments and activities explore electromagnetic radiation and the effect on the Earth.

Students, in groups, explore how astronomical spacecraft and computers create images of objects in space.

Students investigate vision and the anatomy of the human eye. They complete a Webquest, watch a video about the structure of the eye, take an online quiz, answer discussion questions, and read newspaper articles about activities that...

Students conduct an experiment to control the breeding of Japanese Medaka fish. They collect the fertilized eggs and view and record the fish's embryological development daily to compare the stages to human development.

Introduce your class to nanotechnology applications with three demonstrations that showcase scientific principles related to ferrofluids, quantum dots, and gold nanoparticles. Groups will work more closely with these applications in the...

Students experiment with reflections of two plane mirrors placed at a 90 degree angle to see what will be reflected.

Can you beat the odds of cancer? In the first installment of a seven-part series, future biomedical engineers consider how to detect and diagnose cancer. An article on biosensors provides useful information toward this goal.

Take a real close look at your phone screen. What do you see? Here's an activity that provides guidance on how to look at a smart phone screen in order to see the pixels and to see how the phone creates colors and motion on the...

Give your class a chance to show what they know. In the last installment of a seven-part series, pupils summarize and review what they have learned in the series. They present their solutions for creating a biosensor to detect cancer...

You can create a camera with even the most unassuming materials. Learners view photographs and talk about the art. Some background information is included about the camera obscura for you to present before individuals make their own...

Cover one-point perspective through observation and practice. Class members examine several works of art that use one-point perspective, look at magazine images to find the vanishing points and horizon lines, and draw their own city...

In the last portion of the six-part unit, teams perform an experiment with gold nanoparticles to determine which sport drink has the most electrolytes. The nanoparticles are used as chemical sensors and fluoresce in different wavelengths...

Students explore the concepts of rhythm, movement, contrast and texture. They practice using new vocabulary and work on creating a college after designing the arrangement. They self-evaluate their collage and critique their classmates...

Young scholars construct a simple refracting telescope. They calculate the magnification.

Students discuss feelings and explore how to recognize how they are feeling.  For this exploratory lesson students discuss conflict and ways to resolve problems. 

"If you can't explain it simply, you don't understand it well enough" - Albert Einstein. The sixth installment of a seven-part series teaches young scientists about the importance of being able to communicate scientific research and...
