Fourth graders, while working in the classroom and the computer lab, utilizing supporting facts from previous lessons, write a creative story that imagines a world without forests. They write, type and print their stories and turn them...

Fourth graders write a composition on what they think the world would be like without trees. They brainstorm ideas of what they think the world would be like treeless, and creative a story. A rubric is distributed to the students which...

Students investigate the symmetry that is found in nature. They view shapes and patterns in nature while looking at images. Students look for tessellations while obtaining photographs with a digital camera. The information is used for...

Students perform a simulation of the workings of an electron microscope to discover that the resolution will need to improved to detect objects in the nano-scale. They use wooden dowels as detectors to determine the shape of objects in...

Students share what they know about plants and discuss what else they would like to know. The teacher evaluates students' prior knowledge of plants to inform future instruction. Students practice observation and prediction skills.

Pupils identify and analyze the concept of integrated resource management. Then they identify the importance of computers in manufacturing management. Students also identify and define the meaning of acronyms such as CAD, CAM, CIM,...

Students explore the ways in which satellite images provide details of the Earth's surface and how they are capable of taking digital images of the Earth from space they vary in resolution and breadth. They view how cameras and lenses...

In this biology worksheet, 9th graders identify and locate various vocabulary terms found in the study of living things. There are 31 biology terms located in the word search.

Students discover how palaeontologists conduct a dig for fossils and how they interpret the age of the fossils. In small groups, they prepare a "dig site" consisting of bones, rocks and soil layered in a cardboard box. They switch boxes...

The invention of magnifiers that allow us to see things that are otherwise invisible to us has revolutionized science. In this lesson, students use several types of magnifiers to investigate magnification, and record their observations....

Explore the effect of increasing the magnification on a microscope when viewing various samples such as onion root mitosis.

Biological magnification is the term used to described the increasing accumulation of substances in organisms as one looks at higher trophic levels in a food chain. When that substance is a toxin, such as a heavy metal or a pesticide,...

Learn how to calculate the total magnification of a microscope on this concise site. Links to making a slide, questions on the use of the microscope, and other related microscope topics are included on this site.

Have you ever looked through a magnifying lens? Why do things look bigger when you look at them through the magnifying lens? Even though the object appears to get larger, it really stays the same size. Each lens has its own unique power...

Student groups rotate through four stations to examine light energy behavior: refraction, magnification, prisms and polarization. They see how a beam of light is refracted (bent) through various transparent mediums. While learning how a...

A collection of intermediate experiments, for students aged ten and up, for exploring the magnification, reflection, and refraction of light.

This site from Georgia State University Physics Department provides a discussion of how light refracts through the lenses of a microscope. Demonstrates the parts of a microscope and includes an interactive form in which the magnifying...

The premier web site on the physics of microscopy. Includes several pages and numerous Java applets about microscopes and refraction. Thorough, well-illustrated, interactive, fun, and educational. What more can one ask for?

Complete illustrated discussion of energy flow within ecosystems, including discussions of trophic levels, ecological pyramids, food chains and webs, biological magnification, and cycles.

Using the Lens Equation and the Magnification Equations, students determine numerical information about image distance and image size.

While a ray diagram may help one determine the approximate location and size of the image, it will not provide numerical information about image distance and image size. To obtain this, students are introduced to the Mirror Equation and...

These interactive tutorials allow you to adjust the magnification and focus of the object. Requires Java.

This simple lesson plan outlines how to build refracting telescopes and calculate their magnification. Use the follow up lab questions to check for student understanding and view links to other NASA lesson plans.

A full listing of all Edison's battery patents. Not just titles and numbers, but Adobe Acrobat copies of the entire set of drawings and text from each patent application. This is heirloom stuff. With the available magnification, you can...
