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

In this chemistry worksheet, students determine the order of reactivity toward displacement in each of the series listed. Then they respond to several multiple choice questions as they relate to compounds and solutions. Students also...

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...

Written for an introductory organic and biochemistry course, this exam will challenge your class. They label functional groups and stereocenters on drawings of molecules, draw structures given the name, complete drawings of chemical...

In this substitution and elimination reactions worksheet, students complete 11 reactions by writing the structural formulas for the products. If no reaction occurs, they write N.R. They also write structures of the products for 3...

All aspects of the path of light are included in a great summary. Internal reflection and the angles of paths in different materials are explained and the behavior of visible light through lenses and the effect on focal points are...

See the changes, controversy, and innovations that define postwar American art. The onset of the modern art era in American history is well-defined in this slide-show. You'll see how Abstract Expressionism shifted into conceptual, pop,...

Concave mirrors and the images they produce are traditional topics in the physics classroom. This resource explains how to set up an investigation of them, and it provides you with the explanation of concepts.

Viewers use a small, dimmed flashlight to identify the blind spot for both the right and left eye. It is a simple activity to incorporate into your activities during a lesson on vision and the structure and function of the eyeball.

Not only does a concave mirror focus light waves, it can also concentrate infrared radiation into a hot spot. If you have a small electric heater and such a mirror, demonstrate this for your physical science class.

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...

Explore color through an examination of pointillism and light. Class members view Georges Seraut's famous painting on a computer, zooming in and out to see the details and effects of the technique. They then cover how light and color are...

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...

What occurs when a hydrate is heated? Lead your class in exploring the answer to this question as they investigate the properties of a hydrated compound. They heat copper(II) sulfate pentahydrate and evaporate the water...

Astronomy is literally over your head, but this lesson will explain how we study it. Young scientists make telescopes, calculate and compare the light gathering power of lenses, and simulate detection of infared radiation....

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...

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...

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.

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...

The Deepwater Horizon oil spill directly impacted an area of the Gulf of Mexico the size of Oklahoma. A marine biology lesson looks at the impact of an oil spill on the deeper parts of the ocean. Scholars download actual data collected...

How much astronomy can you study with the naked eye? Learn more about the ways scientists explore the galaxy with a short reading passage and set of short-answer questions.

Gaia Squarci's photo essay, Broken Screen, turns viewers attention to the challenges faced by those with visual impairments. After viewing the images, class members discuss why they believe the photographer structured the album as she did.

Does the size of a sample change the physical properties of that substance? It turns out it can! Young scientists combine physics and chemistry to synthesize CdSe quantum dots and record their color properties. Learners should...

Ride the wave to an understanding of refraction! The first in a series of two inquiry-based lessons challenges learners to create transverse waves with two different types of springs. As their wave hits an object, they observe the change...
