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...

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...

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...

Take a look with another perspective. Pupils read to find out what portion of the electromagnetic spectrum a space telescope sees and the difficulties of viewing infrared radiation from other objects in space. Individuals discover how...

Students explore different parts of the eye and functions of each part through a video and a dissection of a cow's eye. They discover different causes of blindness.

Students discover the relationship between lens shape and the formation of images in an experiment. They use three different size converging lenses and a diverging lens to calculate and compare the focal length of each. They graph and...

Get your scholars working at "light speed" with this instructional activity on how different wave frequencies have been discovered and used. The assignment has 20 short-answer questions, set up in a table. Consider re-doing the table or...

Students research the Hubble Space Telescope. In this Hubble Space Telescope instructional activity, students complete a webquest about the Hubble Space Telescope.

Students describe how the sun's rays produce colors. They describe how water causes the sun's rays of light to bend, producing a rainbow.

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. 

The second installment of a seven-part series focuses on the refraction of light and how it affects the colors we see. Learners consider how this concept connects to biosensors for cancer detection.

Bubbles aren't just for children. In the third installment of a seven-part series, teenagers use bubble solution to create bubbles and observe patterns of refraction on the bubble surfaces. Application of this concept to thin films in...

Students examine the properties of lasers and research their types and uses.  In this laser lesson students view several demonstrations.

Middle schoolers develop an invisible security system to protect a mummified troll.  In this security system activity students view a portion of Mythbusters and begin their challenge.

This page consists of a list of the cranial nerves in triplicate. The diagram of the brain that tops each copy of the list is too small for identifying each nerve. Consider giving your avid anatomists one of these lists with a large...

In this chemistry worksheet, students write how many chiral C's are in each of the compounds listed. Then they draw the Fischer projections for all stereo isomers in 5 and in 6. Students also match the correct Fischer projection to each...

Learners study different inventors and inventions.  For this invention introduction lesson students pretend that they are an inventor and come up with their own invention.  

Middle schoolers explore light and color, including how colors are mixed to produce new colors, how light is filtered, and how light is reflected off of surfaces. They read materials provided, complete worksheets, and complete hands-on...

Middle schoolers explore light and color, including how colors are mixed to produce new colors, how light is filtered, and how light is reflected off of surfaces.

These slides give sets of facts and trivia about gamma rays. Your physicists will learn the dynamics of scattering photons and energy involved in gamma ray bursters. The concepts are quite involved making this PowerPoint a nice addition...

In this chemistry worksheet, pupils complete the reactions by drawing structures of major products, indicating important minor products. They also write the structure of the product and describe the stereo chemistry of the product.

Students use NASA satellite data of optical depth as a tool to determine volcanic activity on Reunion Island during 2000-2001. They access the data and utilize Excel to create a graph that has optical depth as a function of time for the...

Students explore the modern applications of robots and create one of the five parts of a robot that could solve a hypothetical public works problem. They study about the use of robots for laying fiber-optics cable in New Mexico by...

Pupils view six optical illusions and explain why the visual system might interpret them the way it does. They explore how illusions distort our sense of perspective, because they deceive us into seeing what we expect to see. Students...
